The Latest Technical Guide to Raising Early-Spring Edamame Seedlings
Nowadays, if greenhouses are used for growing edamame, it can basically be grown all year round. Therefore, in spring, some people begin to plant early-spring edamame, and early-spring edamame is generally grown mainly by raising seedlings and transplanting them. This is very beneficial to the early growth of edamame and can effectively increase yield. So when we grow early-spring edamame, how should we raise the seedlings? Today, the editor brings you the seedling-raising techniques for early-spring edamame. Let's take a look below!
1. Seed and site selection
To grow early-spring edamame, you first need to select good varieties, mainly those with large, plump seeds, good taste and many pods, so as to ensure the yield and quality of edamame and thereby increase its commercial value and growing benefits. Then you need to choose a good planting plot. The planting plot should mainly be soil that is sheltered from the wind, has sufficient sunlight, is loose in texture and has normal drainage and irrigation. Do not choose clay loam, otherwise it is prone to waterlogging and phenomena such as rotten seeds. Then do a good job of land preparation, plowing it deeply, breaking it up finely and raking it level. At the same time, both the seeds and the soil must be disinfected to avoid harm from pathogens and the outbreak of diseases.
2. Sowing and raising seedlings
Early-spring edamame can generally be sown twice, and the first sowing can usually be carried out around the Awakening of Insects solar term. The sowing method is mainly broadcast sowing, and generally about 3 kg can be sown on a bed about 3.5 m wide. After sowing, cover with a layer of fine soil. If the soil is too dry, water it appropriately and soak the soil thoroughly. Then cover with some rice straw to improve the soil's heat and moisture retention and prevent the soil from caking and causing rotten seeds and dead seedlings. After covering the seeds, also use bamboo poles to build arched frames, then cover the arched frames with a layer of plastic film, and press the edges of the film firmly with soil.
3. Timely transplanting
For transplanting edamame to the field, a sunny location should be chosen. When half of the seedlings in the seedbed have grown two true leaves, they can be transplanted. It is best to do this after rain. Before transplanting, the planting field also needs good land preparation, plowing it deeply and breaking it up finely. Then dig furrows, keeping the furrow width at about 15 cm and the row spacing at about 30 cm. Then keep the plant spacing at 25 cm and transplant one or two rows of seedlings on both sides of the furrow. When transplanting, also apply an appropriate amount of phosphate fertilizer, plant ash or farmyard manure as base fertilizer.
4. Strengthen management
After transplanting, management should be strengthened, and work such as cultivating, weeding, fertilizing and pest control should be done well. When the seedlings grow to 25 cm, carry out cultivating and weeding, preferably before rain. During cultivation, an appropriate amount of urea should also be applied per mu according to the condition of the seedlings as a seedling-promoting fertilizer. At the same time, pest and disease control should also be done well according to the actual condition of the seedlings, mainly targeting pests and diseases. Common ones include aphids and bean pod borers. Pesticides should be applied uniformly and used in a concentrated way to avoid pesticide damage that would instead affect seedling growth.
The above is a brief introduction to the seedling-raising techniques for early-spring edamame. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
