2. Amaranth

The varieties of round leaf amaranth were selected.

After emergence, quick-acting nitrogen fertilizer was applied many times to make the stems and leaves grow young.

3. Wax gourd

A variety of green wax gourd with high resistance to sunburn and transportation and dense meat was selected. Before cutting, about 50 kg of livestock manure and ternary compound fertilizer were applied per mu. It is recommended to plant 500-600 seedlings per mu.

About 2000 kg of mature organic fertilizer and 50 kg of compound fertilizer are applied per mu of greenhouse. Land preparation for border, border width of 70 cm, according to plant row spacing 35X50 cm planting, it is recommended to plant about 4000 plants per mu. Suitable time seedling, fixed seedling, supplementary seedling. 30 days after sowing, 20 kg of urea was applied per mu.

Lettuce seedlings were transplanted according to the row spacing of 35X40 cm. It is suggested that about 6000 lettuce seedlings should be planted per mu. After transplanting the living plant, loosen the soil in time, cover the greenhouse film in the first ten days of November and keep the shed tears above 15 degrees.
