Seedling raising techniques of edamame bean in early spring

At present, edamame beans can be planted all year round if they are grown in a greenhouse. Therefore, some people began to plant edamame beans in early spring, while the cultivation of edamame beans in early spring is generally based on seedling transplanting. It is very beneficial to the early growth of edamame bean and can effectively increase the yield. So how should we raise seedlings when we plant edamame beans in early spring? Today, the editor has brought you the seedling technology of edamame beans in early spring. Let's take a look at it.

1. Selection of species and sites

In order to improve the commodity value and planting efficiency, the varieties of edamame beans in early spring need to be selected first, and the varieties with large grains, delicious taste and many pods should be selected to ensure the yield and quality of edamame beans. Then the planting plot should be selected, and the planting plot should choose the soil with shelter from the wind, sufficient light, soft soil and normal drainage and irrigation. Do not choose clay loam, otherwise it is easy to stagnant water and other phenomena such as rotten seeds. Then do a good job of soil preparation, turn it deeply and rake it flat. At the same time, seeds and soil should be disinfected to avoid being harmed by germs and cause diseases.

2. Sowing and raising seedlings

Edamame beans can generally be sowed twice in early spring, and can be sown for the first time at the time of stinging and solar terms. Sowing method is mainly sowing, generally 3.5m of the box surface can be sown about 3kg. After sowing, cover a layer of fine soil. If the soil is too dry, water it properly and water the soil thoroughly. Then cover some straw to improve the heat preservation and moisture retention of the soil and prevent the soil from hardening and the phenomenon of rotten seeds and dead seedlings. After covering the seed, we should also use bamboo pole to make the arch frame, and then cover the arch frame with a thin film, which should be pressed with soil around it.

3. Timely transplanting

The field of edamame bean transplanting should choose the sunny place, when half of the seedlings in the seedling bed grow two true leaves, they can be transplanted. It is best to be able to carry out after the rain, before transplanting, planting the field also need to do a good job of soil preparation, turn it deep and fine. Then dig the trench, the width of the ditch is kept at about 15cm, and the line spacing is controlled at about 30cm. Then keep the plant spacing at 25cm and transplant one or two rows of seedlings on both sides of the ditch. When transplanting, we should also apply an appropriate amount of phosphate fertilizer, plant ash or farm manure as base fertilizer.

4. Strengthen the management

After transplanting, it is necessary to strengthen management and do a good job in weeding, fertilizing and pest control. Ploughing and weeding is carried out when the seedlings grow to 25 centimeters, preferably before the rain. When ploughing, an appropriate amount of urea should be applied per mu according to the seedling condition as seedling fertilizer. At the same time, we should also do a good job in the prevention and control of diseases and insect pests according to the actual situation of seedlings, mainly diseases and insect pests. The common ones are aphids, bean pod borer and so on. Drugs should be used uniformly and centrally to avoid drug damage and affect the growth of seedlings.

The above is a brief introduction to the seedling raising technology of edamame bean in early spring. That's all for today's introduction. This article is for reference only. I hope it can help you all.
