Planting method and yield of Screw vegetable

Planting method: snail vegetable should be planted in loose and fertile sandy soil with good drainage and irrigation conditions, and basic fertilizer should be applied after ploughing, and it can be planted by tuber propagation, the sowing depth is about 5-7cm, the plant spacing is about 15cm, the row spacing is about 30-45cm, and about 1-2 seeds can be sowed in each hole, then covered with soil, compacted and watered. Quick-acting nitrogen fertilizer was applied once in May and July, and phosphorus and potassium fertilizer should be increased in August. Yield: the yield per mu is about 1500 kg.

I. the planting prospect of snail vegetables

1. The snail vegetable fruit is white, taste crisp, sweet and delicious, and can be interplanted with spring wheat and winter wheat. Under normal circumstances, the planting yield per mu can reach about 1500 kg, which is sold to Sichuan, Gansu, Shaanxi and other places. The economic income per mu is about 4500 yuan.

2. Snail vegetable is a kind of green health food, which is rich in nutrition and has a special fragrance. Cooked food is softer than cotton. After processing and curing, it can be used as medicine to treat a variety of diseases. At the same time, it can also be used as a new raw material for industrial extraction of threose. Its economic benefits are relatively considerable.

II. Land selection and preparation

1. Snail vegetables are relatively cold-resistant and heat-resistant, like fertilizer and fear of waterlogging, and have a strong ability to adapt to the environment. Generally, the probability of occurrence of diseases and insect pests is relatively small, so they should be planted in sandy soil areas with good drainage and irrigation conditions and loose and fertile soil.

2. After selecting the planting land, ploughing and disinfection can be carried out in autumn, so as to reduce the source of overwintering diseases and insect pests. About 1500 kilograms of farm manure can be applied per mu, and 100kg compound fertilizer can be applied together. Wait until planting time to level it and rake it fine.

Third, reasonable close planting

1. Snail vegetables are generally propagated by tubers, and suitable varieties can be selected according to soil conditions and local climate before planting. About 1-15000 plants can be planted per mu, and the sowing amount is about 100kg.

2. Generally, after thawing, we can sow seeds in trenches, and we should choose tubers that are robust and disease-free, and the sowing depth should not be too deep or too shallow, about 5-7cm, the distance between plants is about 15cm, the distance between rows is about 30-45cm, and about 1-2 seeds can be sowed in each hole, and then covered with soil, compacted and watered.

IV. Rational water and fertilizer

1. Apply sufficient base fertilizer before planting, apply quick-acting nitrogen fertilizer from May to June, apply 10 kg urea per mu, once in July, wait until August tuber expansion period, increase phosphorus and potassium fertilizer, about 30 kg diammonium phosphate per mu, this can promote tuber expansion.

2. Snail vegetables should be watered in time during drought, but should not be excessive, and should be drained in time in rainy season to avoid rotting roots.

V. late-stage management

1, wait until after emergence in order to loosen the soil, need regular ploughing and weeding, so as to promote rhizome growth, so that seedlings can grow normally, generally weeding large area, can adapt to low toxic herbicides, small area is recommended manual weeding.

2. In the process of plant growth, in order to inhibit its growth, it can be pruned properly.
