When is the double-season 上市 marketed? 茭白别别茭儿,茭笋, 菰实, is a relatively common aquatic vegetable, mainly distributed in China, Heilongjiang, Jilin, Liaoning, Inner Mongolia, Hebei, Gansu and other places. There are two types of cockroach white: single season 茭 (one year old) and double season 茭 (two years a year). Today's Xiaobian focus is on double seasons. The two seasons are listed in April and August. Next, Xiaobian talks about double-season cultivation techniques, as follows.

I. Organizing the fields

Double seasons can be planted in fertile, well-watered land, or in cold soak fields, deep mud fields and shallow lake ponds. The field should be tidyed 15 days before planting in the dry land in winter, once in the land 2 days before planting, and 2-3 days before planting in the winter soaking field. Before the cultivation, the base fertilizer is applied. Generally, 2000 kg of ammonium manure and 50 kg of ammonium bicarbonate + 50 kg of superphosphate and 15 kg of potassium chloride are applied per mu.

Second, reasonable close planting

Double-season planting time is suitable for 3-4 months, preferably in the afternoon. Before planting, the pier is dug, and a small pier can be dug from the bottom with a knife. Each small pier leaves 2-3 seedlings, and the planting distance is planted. It is 70cm, the row spacing is 85cm, and the planting depth is 3-4cm.

Third, strengthen management

After planting white, it is necessary to dip in shallow water, drain in the daytime, and water in the night to make it clear. One week later, 4 kg of urea and 2 kg of potassium chloride were applied, and the same amount of fertilizer was applied after 7-8 days. When the number of white seedlings reaches 30, the amount of field water is controlled within 10cm, and weeding should be carried out in time, which is conducive to field ventilation and promote pregnancy.

Fourth, disease prevention

White rust, rice blast disease prevention and control: the use of conventional drugs such as kesangsan, methyl thiophanate, tricyclazole, chlorpheniramine, diarrhea and other drugs.

Control of white cockroaches, cockroaches, mites, etc.: controlled by insecticidal or pyrethroid pesticides.
