Scallion planting methods: planting time, cultivation soil, watering, fertilizer, planting management.

1, planting time

Planting onion time is generally chosen between early June and early July each year, in fact, onion for the planting period is not so strict, but in order to ensure its survival and growth, it is best to operate in accordance with the standard process. Sowing propagation of green onions, on the other hand, choose in the spring and fall.

2, cultivation soil

The cultivation environment of green onions should be selected from the higher terrain, deep soil, drainage and irrigation is convenient, fertile soil. The soil can be added to a sufficient amount of compound fertilizer, calcium superphosphate, urea and other fertilizers as a base fertilizer, to enhance the fertility of the soil. Ground planting green onions must give the soil deep tilling and raking, open furrow as a ridge.

3, watering

In the growth process of green onions, watering **** divided into four stages. The first stage is in the slow seedling over-summer period, the second stage is in the middle and early August leaf bloom, the third stage is the peak of its growth, the principle of diligent watering heavy watering irrigation, the fourth stage is after late October, slowly reduce the water irrigation.

4, fertilizer

Fertilizer frequency *** counted three times, the first time is in early August after slowing down the seedling to the leaf bloom before the urea fertilizer applied. The second time in the late August leaf development stage, in addition to urea, can also use potassium sulfate follow-up application. The third time is in early September fertilizer, again with urea irrigation.

5, planting management

Pre-planting of large and small seedlings separate, remove diseased seedlings, weak seedlings, too small seedlings and obvious bending of the seedling, plant spacing 35-40 per meter, row spacing of 1 meter, mu planting about 23,000 plants. Planting to avoid onion seedling breakage, planting depth to not bury the onion heart is appropriate, too deep is not suitable for seedling, too shallow to affect the length of the white onion. Planting should be arranged vertically with the leaf surface and planting ditch, which is conducive to dense planting and management.
