Homes that grow onions should share the same feeling, and every fall, their families are prone to minor problems. Either they grow white, they grow small, they sell badly, they don't sell at all on the market; or they look at their strength, they strip them of empty, soft, they store them for days; and there are lots of large onions of land that tend to fall back and fall away, they waste their energy and kung fu。
Many people think that onions are not well grown because they lack fat and water, but most of the reason is that they have not been able to do their jobs since autumn. I planted onions for more than a decade and helped many farmers in the village manage onions, and found that the vast majority of farmers have stepped on the same fault zone: either weave one-time, weave, or weave all the time, and let the onions grow freely。
Onions of onion whites grow slowly by shade, softening, and not by fertilizing and watering. Autumn is a critical turning point in the nutritional growth of onions, where temperatures slowly recede after autumn, where the temperature varies widely between day and night, and where onions begin to grow wildly white and feed. This is a time when three precision fields are prepared, accompanied by corresponding fertilizer, pest control and water-water management, so that light and light can produce high-quality onions that are white, strong and solid, with a high yield and quality。
First, let's be clear: why is the land of qianqiu at the core of onion production
A lot of farmers grow only wind and wind, but not the reason behind it, so they always make mistakes. First of all, it is important to remember that onions grow blue, old and grow slowly, and only if they continue to cover up, can they grow slowly, thickly and tenderly。
And after the fall, the onion plant was fast raised, its roots were shallow, its straw was high, and it was particularly prone to fallback. Once the onions fall and the leaves fall apart, they breed rots, roots and diseases. Rational culture can both fix onions, prevent inversions, and mask soft onions, avoiding hollowness, weakness and greenness at the root。
It is important to remind you of the need not to do so once and for all. A lot of people managed to save themselves, covering a dozen centimetres at a time and covering their hearts and functions directly. Onion blades are used to save nutrients for photosynthesis, and the leaves are buried in their entirety, with poor light from the air, light from the hollows, stop growing, heavy from strangulation, and the whole field is affected. We grow in the old farm, and it's shallow, hard-brain, sub-brain, which is the most economical and prudent way to improve onions。
Ii. Three quick enough enough enforcements after autumn: time, thickness, steps taken
In combination with many years of experience in field practice, the core of the onion has been made three times since the autumn, corresponding to the three accelerations of the autumn, the summer and the white. The timing, thickness and attention of each operation are different, and you can just do it strictly, without a word。
First earth-breeding: before and after the fall, strong roots, solid foundations
Optimal operational timing: 3-5 days before and after the autumn festival, on a rainy morning. At this time, the onions were almost 25-30 centimetres high and stable, having passed the slow-growing period and entered the early stages of rapid growth. It is important to choose the weather and half-dry soil, which after the rain is too sticky to produce soil and which is easy to root。
Accurate operational steps and thickness: this time, it is light ground and the thickness of the land is controlled at 3-5 cm. It operates with small earth on both sides of the line, leaning towards the base of the onion, burying only the lower side of the leaf, and firmly unable to cover the heart and upper parts of the function. And when the earth is gathered, the hand or a little hoof shall be lightened, and there shall be no gap between them, so as not to spill water at a later stage。
Core focus: this is a land that is not thick and steady. For the first time, many farmers have grown too thick to bury their seedlings directly, leading to a halt in onion growth. In addition, weeds must be removed from the fields, and weeds must be fatter and shaded, which can affect the long-term growth of onions. The earth must be crushed, and the earth must be crushed on the seedlings of the onion, so it is easy to crush the penis and cause infection。
The practical problems to be addressed: to effectively fix the seedling system of onions, to prevent a slight fall in the seeding period, to cover the base onions, to avoid the chrysanction of onions, to stimulate onions to tumble down, and to lay the foundations for a fast and long period。
The practical effects: after the first regulation of earth-breeding onions, they are grown and grown, and they are well developed, with little or no seedlings, little and little onions, and no aging。
Second earth-breeding: before and after the summer, strong and critical quality
Optimal operational timing: 18-20 days before and after the summer break from the first field. At this time, onions are up to 40-45 cm, a fast-growing and long gold period of onion and the most critical node of management throughout the year。
Accurate operational steps and thickness: this is an increase in soil thickness to 8-10 cm, which is a medium-term priority. Following the girdles, the cleavages of the walls are evenly ploughed on both sides of the row of onions, which are just as high as the last layer of ground, and not fresh leaves. The top three-four functional leaves, which are the core of onions ' nutrients, must not be buried。
Core focus: three days before and after the planting of the land, the flood is prohibited. The soil is wide enough to sow water that it is prone to landslides and rooting. If the field is small-sized, small-sized onion seedlings, which are not deliberately removed and are properly covered with soil to protect the base, it can grow slowly. At the same time, it avoids high-temperature periods and the high-temperature earth is prone to burning onions。
The practical problems to be addressed are: fast-spreading, coarse whiteness, solving the problem of small and slow-growing onions, further deepening the photo masking effect, avoiding white fibrosis, stiffness of the mouth, deepening the gutter, improving drainage capacity in the fields and preventing the fall rain。
The effect of the exercise is that the large onions that have been laid in the field during the summer, the growth rate of the onions has increased significantly, the staggers have grown evenly, the size of the mantle has not increased to the point where the hair is thin, the flesh is so tight, and there is no preliminary problem。
Third earth-breeding: around white, locked air defence, steady increase in production
Optimal operational timing: 25-30 days before the harvest is the last chance to grow soil and then no more soil. At this point, onions enter the nutrient accumulation period, focusing on quality protection and lock production。
Accurate operational steps and thickness: this is 10 to 12 cm thick, the thickest of the three. The rest of the earth in the cascading floors is designed to cover the whole of the earth up to 20-25 cm, with maximum light-covered onion white, and a small number of functional leaves remain on the top for light co-operation. The soil is then sorted to ensure smooth and smooth communication。
Core attention: this time, we are determined not to hurt the root and the leaf of the onion, not to cause a large amount of soil to be tumbled, but only to do the dotting. In the near harvest, the absorptive capacity of the roots slows down, and the soil-throwing causes premature onions and leaves to turn yellow. In addition, when the soil is dried, it can be ploughed with small water before it can be bred to avoid the soil falling and the soil falling。
The practical problems to be addressed: solving the problem of emptiness, softness, emptiness and aging, maximizing onions and increasing the length and purity of onions, while the structure of the onion is effective in preventing the root causes and outbreaks of disease in the autumn。
Physical effects: following the completion of the last earthbreeding, onions have steadily accumulated nutrients, full and full, clean, empty and soft, resistant to storage and transport, and the commodity rate has increased significantly after harvest。
Three or three times a soil fertilisation technique, not without the fatty, but with the white and the strong
Light-breeding soil is not fertilizing, and onions are not able to keep up; fertilizing indiscriminately and with more fertilisation can lead to growing, white-coloured, hairy leaves. I've spent three years chasing synchronous fats with pedestals, and it's good for farmers。
The first pedagogic pursuit of fatty: steady and strong
This time, you don't need to fatten up, you focus on rooting, securing. Each acre is covered with 200 kg of manure and 15 kg of complex nitrogen-rich fertilizer, equally distributed within the gutter, in combination with earth cover. Farmers are able to decompose their soil and root their roots, and small amounts of nitrogen fattening contribute to the robust growth of the leaves and avoid the loss of small seedlings from fattening and yellowing。
Be careful not to spread it with urea alone, and excessive pure nitrogen fattening can lead to onions growing small and thin, and can easily fall back and empty. After application, the water is slowly watered, allowing the fertilizer to dissolve and absorb slowly, without burning roots or decomposition。
Second tasting (summer): fattening onions, driving long
It's the most critical fertilizing period for onions, which expands rapidly and requires the largest amount of fat. Each acre is used for 25 kg of balanced compound fat, with 10 kg of potassium sulphate distributed far from the root of 5-7 cm and avoiding the burning of roots。
This phase of increased potassium fertilisation will make the onion's trough stronger and thicker and reduce the problem of hollowness and softness from the root causes. Following fattening is accompanied by a permeation of water, which is filled with small amounts of water throughout the journey, which keeps the soil wet and dry and helps to absorb the fertilizer quickly。
Third tasting fertilizer: fattening, locking up against premature decay
This time, the pursuit of fatty is steady, mainly in terms of integrity, without the application of nitrogen fertilizer, and to avoid later periods of greed. Potassium sulphate is sufficient for 12-15 kg per acre alone, and potassium phosphate can be sprayed on the side of the leaves, evenly on the reverse side after water is diluted。
The central role of this fertilization is to promote the accumulation of onion nutrients backstreams, to make onion whites more compact and taste better, while at the same time prolonging the function of green leaves, preventing early foliage and yellowing and safeguarding later yields and quality。
Iv. Water management on the onions after the fall
The onions were made, fertilized, and the water couldn't keep up. The autumn weather is cold and noon hot, the water is not watered at the right time, the water is not watered at the right amount and leaves are prone to rotting roots, hollows and yellow leaves。
The core principles are watering, dry and wet, and watering before and after the earth. Three times the soil was protected from wet soil after the rain, and the soil was adhesively wet. After two to three days of each pastry, water is poured on the basis of the soil's damp condition, giving the soil a time to settle。
The autumn is characterized by heavy rainfall, which must be followed by the timely clearing of trenches, the complete discharge of water from the fields and the accumulation of water from the onion roots for more than 24 hours. In the event of prolonged drought and no rain, small water can be poured every 7 to 10 days without heavy water, avoiding soil sheeting and oxygen deficiency。
V. Autumn onions, common onions and insects
After autumn, the temperature is appropriate, and the disease has a high incidence, and the pests eat leaves and the disease's roots are directly causing onions to grow, empty hearts and lower yields. I have prepared for you the most common and best treated pests in the field, with simple and safe medicines that farmers can take directly。
Leaffly control
The larvae fly is the fall onions head infestation, where the larvae enter the blades to eat the meat, form white insect tracts, destroy the radiant co-operation of the leaves, have no nutrients, and are naturally empty. When the leaves were found to have little albinism, they were used in a timely manner, using 1. 8 per cent of the avil cream, sprayed on a regular water-to-water scale, focused on the positive and negative side of the leaves, sprayed once at an interval of seven days, and sprayed twice in a series of times, and completely infested。
Onion control
The small size of the horse, its hidden depth, and its special use in onion sap juice lead to white, curly, dry and long. The focus is on early detection, early prevention and treatment, the selection of generic accelerants, the application of flat sprays, the early cleaning of weeds and the reduction of pest caches。
Soft corruption control
Soft decomposition is the result of bacterial diseases, with water accumulated after rain, poor ventilation in the field, and excessive stifling of the soil. After the onset of the disease, the onion had softened its base, rotted, stenched, and a whole system of decay. Prevention is greater than treatment, and water is drained in time after the rain to avoid smothering the fields. In the event of a minor outbreak, the strain is removed in a timely manner and destroyed outside the field in order to avoid cross-infection, while bacterial agents are administered to prevent the spread。
Frosty control
In the autumn, the rains were continuous and damp, with a high risk of frosting, with yellow spots and white drying of the leaves, and in severe cases the whole of the fields were dead. Daily ventilation in the fields, rational planting, timely wetting after rain, selection of routine frosting agent spray for prevention at the beginning of the disease, one weekly interval, and better control。
Vi. Comprehensive comprehensive comprehensive quipment + high-yielding
The whole story's real-life focus, and i'm going to make it easy for you to keep your mouth shut when you're busy: the foundation is solid, the onions are thicker in the summer, and the soil is sealed in white; the soil is unheard and wet, the soil is not dry; the soil is not dry; the soil is warmed up and warmed up before and after the rain; the roots are drained and the disease is protected。
Once again, the core elements of physical exercise are: three high-temperature, high-heavy, non-one-time pyrotechnics; two high-temperatured, pre-slender, medium-term onions, post-salvation; three dry water and wet water before the rain; and four early prevention of pests and insects, which preserve the function of the leaves, with sufficient nutrients to feed them with natural strength。
