Field management technology of snow vegetable

Snow vegetable, also known as Xuelihong, is a common vegetable with excellent taste and good nutrition. It is deeply loved by urban and rural people. As its market demand expands, the planting area becomes wider and wider. But if you want to grow it well, field management is extremely important, so let's take a look at the details.

1. The seedlings are fixed

When the seedlings grow the first true leaf, the first seedling can be carried out, and this time the seedlings can be densely planted; when 2-3 true leaves are grown, the second seedling will be carried out, and this time the long seedlings, thin seedlings and disease and insect hairs will be cut, and the distance between the seedlings should be controlled at 3-5 cm. When the seedlings grow out of 3-4 true leaves to fix the seedlings, then the seedlings basically grow neatly, without other operations, the distance between the seedlings can be expanded to 10 cm.

2. Transplanting and planting

Transplanting can be carried out when the seedlings grow to about 15 cm and have 5-6 true leaves. It is generally carried out in late September in winter and November in spring. First of all, the seedlings should be raised when transplanting, and enough water should be sprayed on the seedling bed to soften the soil, and at the same time, be careful not to harm the roots of the seedlings, so as not to affect the survival rate of transplanting, and then transplant according to the size of the seedlings. Generally transplanting 4000-5000 plants per mu in spring, but it can be increased to 5000-6400 plants per mu in winter. The soil is dry when transplanting, and the fixed root water can be irrigated once to improve the survival rate.

3. Topdressing in time

Before transplanting, it is generally necessary to apply base fertilizer, mature and high-quality organic fertilizer per mu of 1500-120kg per mu to ensure the rapid growth of the plant, or it can be replaced by compound fertilizer. After transplanting, topdressing was carried out for 2-3 times according to the growth situation, and urea was applied 5-6 per mu each time, and it was best to dilute it with water.

4. Pest control

The summer and autumn season is the high temperature season, at this time is the period of high incidence of diseases and insect pests, the main pests are aphids, cabbage moth, earth tiger and so on; the main diseases are virus disease, downy mildew, root swelling disease. The prevention of diseases and insect pests is the main. In the seedling stage and growing period, the mixture of Lesbon, dichlorvos and phoxim can be sprayed every 7-10 days, which can play an excellent preventive role.
