Today, re-entry was launched in action (ii) agro-technology: the time of growing onions and environmental requirements. Let's learn, girls
I. Onion planting conditions
Soils: onions are suitable for soil cultivation at ph6. 5-7. 5, nursery grounds require eutrophication, sufficient bottom lumber, seedling periods prevent soil sheeting, seedlings start to grow rapidly and fatten once, soil moisture is controlled 10-15 days before planting to prevent runoff。
2 fertilizers: onions are popular and require a balanced application of nitrogen, phosphorus and potassium. Nitrogen fertilizer is more demanding in the pre-growth period and more phosphorus and potassium in the later period. Particular attention should be paid to the application of phosphorus fertilizers, as the lack of phosphorus fertilizer can lead to poor growth and lower yields. At the same time, attention should be paid to the presence of onion sulfur in the soil and the lack of sulfur in the soil, which will affect the effects of increased production。
3. Temperature: onions are resistant to both cold and heat. Although temperature does not generally have a significant impact on the growth of onions, appropriate temperature conditions favour high quality production。
4. Humidity: low onion hair and low capacity to absorb water. The roots are mostly distributed on the surface of the soil, wet and require higher soil moisture, but the roots are afraid of flooding, and high temperatures and humidity are highly likely to cause death。
5. Light: onions require moderate light intensity. There is no need for strong light, as onions are still able to obtain good light under densely planted silos. Strong light adversely affects the growth of onions, leading to aging of leaves, increased fibres, reduced quality and even loss of edible value。
Ii. Timing of onions
01
Autumn planting time
In the first year, seedlings were planted in early september, winter with seedlings, mid-may of the second year, pre-winter harvests, cellars or field winters, and in the third year, spring, flowers were drawn and seeds were collected over seasons. Plantation-time seedlings can be put on the market as onions between early may and late june, or can be provided as onions in the early summers, either by flat bushing (breeding onions) or by reducing the range of the strains。
02
Spring planting time
In the early spring, when the soil is unfrozen, seeded, supplied as onions before the onset of the summer, or harvested as onions or onions in the year after planting, may also winterize as onions of sheep or as seed stocks。
03
Summer planting time
Most of the seeding took place in late july and early august, and was also called onions. During the winter, the plant was large enough to complete the springing process, and the next spring was early and quickly flowering. They usually pick up onions and come on the market。
Iii. Onion cultivation methods
1. The pre-plant size and size of seedlings are separated to remove the sick, the weak, the perm and the visible bending of seedlings at a distance of 35-40 units per metre, at a distance of 1 metre, with an acre of approximately 23,000. They are designed in such a way as to avoid a break in the seedlings, so as not to bury their hearts, so as not to grow too deep and so light. Leafing should be arranged vertically with planting ditches in order to facilitate planting and management。
2. A planting tool may be designed with a gardening iron or pole of about 1. 5 cm in diameter, with a shallow hole, vertically to the ground, then a seedling inserted into the ground, then slightly upward, so that the root must be stretched down and the seedling kept straight. If it bends, and it bends at later harvests, it becomes a subtext。
3. Plantation is to be planted on the same side of the onion ditch, thus facilitating drainage after the rain。
4. When planted, the pine soil on both sides will be crushed and water will be poured。
