Many old people grow onions in their homes every year, watering them with grass, and taking care of them. After autumn, they relax and feel that the seedlings have grown into stale shapes. But when the real harvest comes, the onion leaves on the ground are so big, they are so big, they're white, they're small, they're small, they're low, they're low on the market, they're busy all summer, they're not good enough. In fact, the gradual increase in the temperature of the day and night after autumn is the key long-term life of onion nutrients deposited downwards, vertically and vertically stretched to thicker, during which the final production and quality gap is clear。
For years, i found that the vast majority of farming households did not grow onions, not bad seed varieties, but that daily management stepped on a lot of mistakes. Some only know how to follow fat water, and all the nutrients are for the long leaves on the ground, and some for the land
No, once-in-a-lifetime heavy earth overstretchs the onions, suffocating them directly; there are those who leave their fields with water, weeds that grow crazy, roots that grow in poor conditions, and their ability to absorb water fattening is severely compromised. Today, taking into account the experience of field practice, we share three highly ground-based management approaches, which can be operated without spending high-cost agricultural resources, and with a steady increase in the overall quality of the onions。
I. Battery layered plastered trees that guide onion long vertical stretches
To be white and white, earth is the most critical step in the whole management. The earth covers up onions and separates the sunlight from the surface, which does not produce a green layer, and in a light-shielding environment, the strains continue to feed the luminous co-operation of leaves to the subterranean troughs and to grow vertically. It is important to bear in mind that the soil cannot be covered at once too thick and that it is most secure in three stages。
1, 3-phase earth-breeding time and land cover standards
The first field selection, about a week after the fall, gives priority to wet and soft weather operations after the rain, soil is sorely decorated, and it is not easy to break the skin tissue of the large onion base when the soil closes. The earth covers only one third of the onions of the ground, and it is important to leave the freshly breeching leaves in the middle of the earth outside of the earth, once their hearts are sealed by dirt, their aerobics are inadequate, the onions stop growing new leaves, and the whole crop of growth stops。
The second earth cover is carried out at intervals of about 20 days, a period that officially enters a period of rapid development, allowing for the proper lifting of the soil height and the burial of the vast majority of it into the earth. When the soil is covered, the earth is attached to the base of the onion, it is lightened, and no holes are left in the earth, which can cause local onions to turn white, and the hard ground is solid enough to plant onions, and it is not easy to fall when the trees grow. Once the onions bend, the internal nutrient transmission channel is blocked, and the onion grows white and stops。
The last light-breeding soil, which is 20 days away from harvest, will not be required to increase the amount of land so that it will be so easily reinforced as to protect it from the slopes of the plants brought about by the wind and rain, and to protect the later nutrient accumulation, which is already in shape。
2. Practical manoeuvres and high-frequency area evasion
In the process, following a ditch between two rows of onions, the mud on both sides is slowly pressed towards the root of the onion, moving as softly as possible and not pulling the old leaves out of the outer lobe. In the event of damage to surface skins, the high humidity of the field is highly susceptible to the growth of all kinds of harmful pathogens, causing underlying decomposition and soft decay。
Grounds that are low-lying and easy to store in the rain, and earth-breeding operations are carried out with a view to repairing the drains of the cisterns and raising the planting table as appropriate. Rainwater can be quickly drained out of the field along ditches, root systems are not immersed in the water for long periods of time without oxygen and decomposed, root systems are healthy enough to absorb water nutrients and onion growth is fundamental。
Here it is important to remind you of a high-level mistake: do not try to save yourself from the one-time thickness of the earth, which is the easiest way to delay onions. The whole onion is not swollen and wastes the golden period of its development。
3. Practical benefits from the partitioning of land
The earth covers the light, the white skin is clean, the goods are sold better and acquired more advantage; the plant is solid enough to avoid a fall in production in the middle and later stages; artificially restrained horizontal growth, the nutrients are transmitted downwards along the troughs, the skin is stretched down, the internal flesh is sorely full that it is not easy to break free。
Ii. Phased adjustment of the fertilizer ratio, inhibition of leaf-leaved students, and nutrient orientation for onion development
Before autumn, the onions were mainly dominated by leaves on the growing ground, and nitrogen fertilizer could be moderately high, and if it were to be applied on a single scale after autumn, it would only allow onion leaves to grow wildly fat and fat, large leaves to continue to consume nutrients in the soil, underground onions to lack adequate nutrients, and thinner and thinner. Following up on fattening is the principle of hard weight and hard work, the fertilizer ratio is adjusted in stages and nutrients are concentrated on on onions。
One week after the fall: growing a root base fat
Select a balanced ratio of compound fertilizer, digging in shallow ditches between two rows of onions, applying fertilizer at a distance of about 10 centimetres from the root of the onion, rather than pressing the roots of the pile, the local concentration of the fertilizer is too high to burn the roots, and there is what farmers often call burning a dead seed. When it is done, it covers a thin layer of soil, pours water over it, so that the fertilizer slowly dissolves into the depths of the earth and the roots absorb nutrients smoothly。
The core objective of this competition is to preserve the growth of the root system, to promote its rooting deep into and around the earth, to widen the extent of water fertilization, to lay the foundation for the growth of nutrients, to stabilize the efficiency of subsequent absorption and to build up sufficient stocks of nutrients for onions to grow。
Before and after the second pedestal: onion pull long enough to increase key fat
This stage is a peak period of platinum length and flesh abundance, requiring an appropriate reduction in nitrogen fertilizer application and an increase in the supply of potassium fertilizer. Potassium fattens are able to form on the basis of internal cell tissues, which are not easily softened by hollow hearts, and when the onion matures, it is stored and its mouth is soft. It is also applied in the form of shallow ditches, where the application is followed by a small water recharge, and when the fat is fully integrated, the roots are gradually absorbed。
Land parcels, with weak land capacity and years of cultivation of poor soil fields, can be combined with fertilizing leaves in the middle of two rounds of soil fattening, spreading evenly across the onion blades. The application time is preferred for the cooling of the evening temperature, the water evaporation rate is high in high-temperature environments, and the medicine is attached to the leaves for a short period and the absorption effect is significantly reduced. The right amount supplements the various trace elements, slows down the yellow and early decay of the lower leaves, and guarantees normal luminous co-operation of the leaves to produce nutrients, which are constantly transmitted to the white parts。
The point of hiding from the pit that must be kept in mind in the pursuit of fat
First, the elimination of one-time intensive fertilization, the sharp increase in the concentration of nutrients in the soil, the loss of water from the onion cells, and the resulting burning of a stiff seedling that takes a long time to recover slowly; second, the absence of direct soil fattening during extreme drought, the inability of fertilizers to dissolve piles within the earth floor, and the subsequent water recharge that easily produces damaging roots in an instant; and third, the fact that successive rainy weather does not catch up with fattening, the soil is saturated, and the loss of fertilizers as rain washes away, increasing the cost of seeding and breaking the soil's internal nutrient balance。
Scientificly controlled water combines with day-to-day field care to protect the roots from the disease and clean up the obstacles to white growth
Fertilizer management complements each other, water is well managed, roots are not damaged by oxygen in a dry-wet-balanced environment, nutrient absorption efficiency is fully filled, together with simple routine field management, reduced risk of infestation, steady growth of onions and steady growth。
1. Water as required to maintain a dry and wet balance in the field
The temperature remained high during the day after autumn, and the soil surface water was evaporated at a high rate and air humidity was relatively high in the morning and evenings. When the surface layer is seen to be dry, it is then arranged for water-watering operations, with small water being used slowly throughout the course, and it is strictly forbidden to fill the ditch with large water. Water is not available for long periods of time, onions are suffocated with oxygen in the wet soil and decay, and the capacity to absorb water fat is directly and significantly reduced。
The selection of water is carried out early in the morning or evening, the temperature is high in the afternoon, the temperature of the soil is cold and hot, the root system is highly irritated by stress, the absorption function is reduced in a short period of time and the nutrient transfer accumulation is delayed. Following the completion of the two concentrations of soil, the water is duly stretched and the soil is best kept micro-humid. The soil in the field is wet for long periods of time and the onion base is suffocated in a wet environment, which is highly susceptible to bacterial disease and the presence of rotting roots. The first half of the month before the harvest is approaching a gradual reduction in the amount of water being poured down, a slight control of water containing internal onion moisture, a tight storage of onion meat, and a lack of easy decay during harvesting and transport。
2. Timely weed ventilation and pre-disease prevention
It is important that weeds grow early and manually removed, that weeds compete for water and fertilizer resources in the soil, and that they also block ventilating light from the walk, that the fields are closed and humid and that bacteria and eggs are easily breeding. Weeding is removed with the greatest possible hand-to-hand and does not dig deep into the earth floor, and large-scale shaking of the onion root system results in loose roots and a decrease in the ability to absorb water fattening。
In the course of the day, the patrols observe the position of the onion's base and the leaf clips, and if they detect anomalies such as yellow-haired leaves, soft-haired base hairs, first-time ventilation, removal of already ill and dried-up leaves and cutting off the path of the bacteria to continue spreading. As long as the field is well ventilated and the humidity of the environment is naturally regulated, the vast majority of highly wet-induced diseases can be effectively reduced. Priority is given to optimizing the field's growth environment to reduce the probability of disease, using officially registered agricultural medicines for large areas of disease, applying strictly in accordance with the specifications and not increasing the dose。
3. Cleaning of aging leaves at the bottom to reduce inefficient nutrient consumption
The lower half of the onion is attached to the ground with yellow leaves and dried leaves, which no longer produce nutrients and which accumulate moisture on the surface and become hotbeds for disease. These useless leaves are removed from the working environment, which improves the conditions of inter-walk ventilation on the one hand, and plants that no longer provide extra nutrients for the dead leaves on the other hand, all of which concentrates on onion growth, on the other。
In the fall phase, the onions will be fully bred, and the three core agricultural tasks will be captured: sub-spectrums will be used to regulate the cultivation of the soil, and the shades will guide the longitudinal growth of the onion; a phased scientific process will be conducted to adjust the nutrient structure, inhibiting onions and feeding the onions; and precision will be used to control the drying and wetting of the field, along with basic pipes such as weeding, cleaning the leaves, and disease prevention. The whole management package does not require a high level of input, but is based on a much more sophisticated and well-regulated field management on a day-to-day basis, on a well-regulated basis, onions that are grown to be white and hard to eat and sell on a daily basis。
I'll give you a good farming excuse: a long, hard-working onions, a few fats to make up for the earth, running the water so that it doesn't get too bad, and growing a good income. It is a simple and practical set of earth-based practical skills, and it is felt that content can be useful to celebrate the preservation of the collection, which is transmitted to the neighborhoods around which the onions are planted, so that the harvest can grow in a steady and scientific manner。
