Hello, i'm the star watcher on the gobi, who brings you up to date every day
September is the critical stage in the development of the autumn beacon, and many of these problems will be encountered by a wide variety of people: the saplings of cabbage grow in green oil, the leaves are spread out large, and look at the glamorous growth, and when it comes to wrapping up, their hearts are loose, their internal shell is empty and they tend to rot. A lot of people think it's not enough fertilizer to hunt for urea, and the longer the leaves grow, the less the dishes are wrapped and the more the disease continues。
In this case, there is a high probability of poor seedling management. Rather than drying up the cabbage to half-life, a water-control fatty field operation before the end of september, forced the root of the cabbage to go down, suppressed part of the ground, adjusted the nutrient distribution and left the nutrients to the late-concertation ball. Both rural and home gardens grow mid- and late-cooked cabbage, which is done in september, so that later cabbage is tightly wrapped and resistant to flooding, and so is the probability of a broken root and a dry heart。
This paper is written in a popularly grown and practiced language, which explains exactly what a sapling is, when a sapling is activated, how to control the water and fattening, how to judge how a sapling is in place, what conditions are not in place, how to tie up the fatting after the saping, and how to comb through the common pedestals and help people avoid the problems of over-saping, rotting roots, and unconcerting。
First, why do cabbage have to get down in september
In september, the temperature was high, rainfall was high, the soil was abundant, and the lichen leaves on the large cabbage fields were prone to crazy lengths. The leaves are large, thin and light, with the bulk of nutrients being consumed in the outer leaves, with roots floating in shallow soils and not laced deep. When it enters the convulsion stage, the roots are weak and the nutrients fail to keep pace with the growth of the vegetable ball, there are loosely packed hearts, small kitchen balls and a high incidence of heart disease。
The principle of scavengeration is to create moderate short-term water coercion and reduce surface moisture in the soil. In order to survive, cabbage actively stretches the roots deep into the earth, lengths the main roots and increases the number of sides. At the same time, the growth rate of the leaves on the ground has slowed, the wall of the leaves has become thicker, the leaf colour has changed from light green to deep green, the strains have become more resistant and are not easily immersed in the rain, and the risk of frosty and morbid disease has decreased. When the seedlings are completed, water is given to fattening, and a strong root system is able to absorb the fatty quickly, and nutrients are passed on to the kitchen balls, so that the heart falls。
There are a few typical problems when you don't have to be a sapling, and you get fat and fat all the way to your heart。
The first is that the outer leaf is long and the leaves are thin and the leaves are long, and the nutrients are consumed in the outer leaf, and it is slow to enter the heart, or it is loose and soft。
Second, it is shallow, with heavy rains in mid-september, and water in the ground, and the shallow roots are prone to a lack of oxygen and to the emergence of rotting gangs。
Thirdly, in poor resistance, high temperatures and humidity, the outbreak of frosty disease and morbid disease is faster, and it is difficult to recover damage even if drugged later。
However, a permutation does not amount to drought, overcrowding and a prolonged severe drought, which inhibits the normal development of cabbage, delays condensation, small-scale planting and a direct decline in production. So it's one degree to see the seedlings, the earth and the weather, not the one-size-fits-all days。
When did the cabbage grow in september? Long
Autumn cabbage, in september, was in the lotus slot, that is, after the horticulture tree, and had not yet begun to be wrapped up, which was the best window period for the sapling。
In the form of a plant, the large cabbage produces 8-10 large leaves, has a congested tree, and has not been condensed with its heart before planting it。
At the point of time, most of the northern part was concentrated in the middle of september; around mid-september in the hwang hwai sea region; and later in the southern part, the time of the scavenger would shift back and forth accordingly。
It can be extended to 10 to 15 days for long periods of sapling, 7 to 10 days for regular plots of land, which are particularly strong, with heavy soil adhesive and heavy rainfall, and less water for sanded land, which ends in seven days and does not last long。
The emphasis here is on different varieties: pre-cooked cabbage is not recommended for incubation, early-cooked varieties are short-lived, which delays growth and affects normal ball-breaking; it is mainly aimed at medium- and late-cooked cabbage, which is the main type of cabbage we store in winter。
In four cases, don't do it
1. The sapling itself is weak, leaves are yellow and small
2. Sand soils with poor water conservation capacity and persistent drought
3. The roots have not yet been fully restored as soon as the plant was installed
4. Beverage varieties with early and short reproductive maturity。
In the case of the above, forced incubation can only lead to the deterioration of the body, the abandonment of the management of the body, normal and small waterwork, and the increase in its weight。
Iii. Crawling cores: water control, fat control, co-opting
There are three core jobs: water control, fat control, and weeding in china, which are coordinated only by water control, which is less effective。
1. Water control: not completely dry and dry
A lot of people understand that a scavenger is just a little waterlessness, and it's a mistake to dry up to a leaf. The criteria for moisture: the soil surface is white, there are tiny cracks and the surface is 2-3 cm dry, but the soil below 5-10 cm is still microtide and can be squeezed into clusters and cannot be fully dry-dryed。
Operating process: before the seedlings begin, pour water once, fill up the bottom and then stop pouring. The period was not entirely free of water。
In the event of a continuous high-temperature storm, five centimetres of earth's surface is dry and cabbage is not restored, small amounts of water will have to be poured to make up, water will not be poured, and water will not be extended, otherwise the dowling effect will simply end。
In the event of a rainy weather, it is important to drain the water from the fields in time, draw the pine soil in time for the rain, wet the soil, do not produce a permutation control, and suffocate the roots and induce them to rot。
The simple test is that, at high temperatures at noon, the leaves in the field of cabbage tend to fall slightly, so that they can recover in the evening and at night, which is the proper state of crouching; if, by the next morning, the blade remains in a state of plumbing, indicating that the drought is excessive, the water must be filled immediately, and the seedlings must end。
2. Fertilizer control: stop pursuing nitrogen fertilizer in the sapling phase
Following the start of the cramming, the pursuit of urea, high nitrogen-speed fertilizer is strictly prohibited. Once the nitrogen is on, the blades recover and the seedlings fail。
Fertilizer time nodes are to be distinguished: before a moisture, if the plot is not fertile enough, a fertilizer can be applied one time in advance, and when the fertilization is completed, it can enter the moisture stage. Crawling runs the whole cycle, doesn't chase fat. There's plenty of floors, and no extra fertilizer for the whole time。
It is a high frequency error that many farmers are accustomed to seeing cabbage in poor shape and to pouring a urea during their stay. Nitrous fattening causes the outer leaf to grow, the roots to fail to ligate, the post-concertation and the disease to increase。
3 - a necessary step in the field
After water has been poured before the saplings and the soil is dry, it must be ploughed. Medium-farming is used to break compacted soils, increase soil permeability, cut off small roots on the surface, and force the root to grow downwards, while protecting the larvae and inhibiting weed growth。
China remembers the mouth: the head is shallow, twice deep, and don't touch the root of the cabbage。
For the first time, it was three to four centimetres deep, with the main objective being to break the surface sheeting, remove weeds, and, close to the root of the vegetables, make sure that the main root is not injured。
The second time, mid-crawl, can deepen to 5 to 6 centimetres in rows, deep-dry ditches, shallow sorghum around the root of cabbage, finish the last till before sealing, and then stop digging the ground after the scavenger seal, so as not to scratch the leaf handles, and the wound is susceptible to soft fungus。
The small size of the family garden, the absence of a beech, and the use of a rake to draw the surface between the sides, do not need to be dug deep。
Four, how do you figure that acreage is in place
Many farmers have poor end-of-life control, too short time for incubation, and too long time for incubation, which has resulted in injuries to the plant and delays in conceiting. Three intuitive features of the plant, which are basically met simultaneously, will put an end to seedling management。
First, the colour of the leaves has increased markedly, from light green to deep green, with thicker leaves and thicker leaves。
Secondly, at noon, the leaves of the outer lore are slightly atrophy and can be fully restored after dark。
Thirdly, cabbage leaves are beginning to converge internally and prepare for the condensation phase。
When cabbage is seen all day, it does not recover at night, no matter how long it lasts, it is stopped, water is poured and cannot continue to carry it。
When a seedling is finished, the weight of the water compost is the top priority
It's not like you're doing everything. A lot of people are doing well, managing the rollover later. At the end of the scavenger season, the cabbage enters the heart pump period, which is the highest demand of water for the whole reproductive period. This is an inappropriate step, with a range of problems such as cracking balls, rotten roots and dry heart。
One, water, water, water
The seedlings end and the soil is managed over time to prevent one-off flooding. Water is poured once, the soil slowly recovers, then the soil is stabilized and humid, and water is poured once in 5-7 days in order to be dry and wet. Soils cannot be drier and damp, and suddenly water follows drought, and cabbage balls can break open and damage root systems. Water must be drained in the rainy days, and the fields must not accumulate water, which can easily cause a morbid disease。
It is 7-10 days before harvest that water will be reduced, water will be stopped, cabbage will become more resistant to storage, water will be overdone and storage will be vulnerable to failure。
Two. Get fat. Focus on potassium fat
Once the scavengers are over and water is poured, the “cream fat”, which is the key fat for the early stages of the convulsion. At this stage, the urea can't be smothered at all, and the excess of nitrogen fattening continues to cause the outer leaf to grow. Fertilizer mix is dominated by compound fattening, increasing potassium fattening, appropriate nitrogen fattening, and supplementing calcium fatting to prevent cabbage from drying out the heart (breeding)。
Reference amount for daejeon: 15 + 20 kg of compound fertilizer per acre and 8 = 10 kg of potassium sulphate. It is possible to spray potassium dihydrogen phosphate with calcium folate at intervals of 7 to 10 days, with two successive applications, to replenish potassium calcium, to promote condensation and to reduce dry burning。
A small family vegetable garden, with a small amount of potassium sulphate combined with consumable organic fertilizer, uses as little as possible single urea。
Try to get fat and bury it in a ditch, so as not to spread it directly over the root blade of the cabbage, avoid burning leaves, and then water the dissolved fertilizer。
Vi. Common areas of error that can easily be stepped upon during sapling
Zone one: all cabbages have to be down
Pre-maturized varieties, weak seedlings, poor sandy plots and forced seedlings are counterproductive. Crawling is a dynamic medium- and late-lated cabbage, which is not an option for cabbage cultivation and depends on the flexibility of the sapling。
Zone two: crawling is a total drought, no water
The complete loss of water, sustained high temperatures, damaged root systems and, at a later stage, the difficulty of restoring even water, delays in the enzymes and decreases in production. The criteria for moisture are surface drying and microtide in the lower soils, which require water recharge in case of atrophy。
Mistake three: i saw the seedlings yellow while incubation. Su
Saplings are yellow and, in many cases, are forced by drought, not by lack of nitrogen. In the sapling phase, follow up on nitrogen fertilizer, and immediately eliminate the effects. If the seedlings are indeed thin, then it is not suitable in itself to get out of the seedling process and maintain normal water fertilizer。
Zone four: once the sapling is over, it'll be full of fat
After a long period of water control, the soil suffers from a shortage of water, a sudden increase in fattening, a sharp change in the osmosis pressure of the root system, a vulnerability to injury, and a fracture of the leaf ball. A gradual recovery of water fertilization。
Zone five: water only, no plowing
Light-controlled water is inhospitable, the soil sheet is in poor condition, the roots cannot be fixed, even if the water is controlled, it does not have the effect of placing its seedlings on the ground。
Vii. Oda, small vegetable gardens and flower basin cultivation programme
Open field cultivation (north, hwang huaihai autumn)
In september, a fat-watered tree was put in place, a plough was cultivated in the rows, and the sapling was activated between 7 and 12 days. The rain-coated land pays attention to draining water after the rain, and when it rains, it is carried out in time. At midday, the blades recovered slightly in the evening, ending incubation, pouring out water, chasing out the drum fat, then keeping the soil humid and controlling frosty, morbid and green insects。
Home garden gardening
The size of the plots is small, so be careful not to grow too densely. Water was pouring in before the saplings and the little rake ploughed the surface between the lines, stopping the heavy water. The soil of the small vegetable gardens is poor and the soil moisture is observed, and the soil is dryed up quickly to reduce the number of days of scavenger. After the scavengers have ended, they are supplemented by consumable farmers' fats with potassium fat to prevent the drying of the cooking heart。
Flower-pot foam box balcony for cabbage
They have limited soil capacity, poor water retention capacity and do not recommend forced seedlings. Vegetable root is limited in growth space, and water control can easily cause direct drought. The plant is based on dry and wet management and does not copy the daejeon plume operation。
Eight. You're doing well, or you're having a bad heart attack
Some of the cabbage cadets are fully covered, and later cabbage is still loose and other factors need to be checked。
First, the late delivery of nitrogen fertilizers and the lack of calcium phosphorus, even when the seedlings are in place, the outer leaves continue to grow and the tightness of the heart is affected。
Second, the soil lacks calcium, there are dry charries, and the heart rots loosely within the heart, which is to be addressed by the supplementation of calcium fats with the leaves。
Thirdly, the planting time is not right, the planting time is too late, the temperature is rapidly declining at a later stage and the cabbage growth cycle is insufficient to cover it。
Fourth, pest and disease hazards, frost, larvae destruction of functional leaves, insufficient cooperation, insufficient nutrient production, and poor care。
Scavengers are basic management and require a high yield of cabbage, with a combination of fattening, pest control and planting time。
Crawling is a key part of the september management of autumn cabbage. The essence is to control the ground, push it underground, raise a strong root of the cabbage and reserve it for later care. However, seedlings are not a panacea, and can only be grown in a tight and durable stock of cabbage if they are not adapted to soil, sapling, weather and a fixed set of days。
