How to grow edamame? A detailed guide to planting time and methods
Edamame, also called vegetable soybean, is rich in nutrients and is cultivated all over China, but because of the climate differences between north and south, its planting time varies slightly. So when is the right time to plant edamame? And what are the planting methods? Let's take a look at the planting time and methods of edamame with Qinnongwang below.
Planting time
There are many edamame varieties, and different varieties adapt to different environments, so planting times all differ. Early-maturing varieties are planted in spring, when temperatures are lower, so they need to be sown and raised as seedlings; generally they are sown in February-March, can be planted out at the end of March, and can be harvested in June-July. Mid-maturing varieties are planted in summer and can be sown directly in April-May, with harvest in July-August; late-maturing varieties are planted in autumn, direct-sown in June-July, and harvested in September-October. In southern regions, planting can also be delayed, sowing in July-August and harvesting in September-November.
Planting methods
1. Soil selection and land preparation
Choose a fertile, deep soil plot with good drainage. In the winter of the previous year, deep-plow the soil and use sunlight to bleach the soil white, which can eliminate part of the pathogens in the soil. Before sowing, apply sufficient base fertilizer along with land preparation; farmyard manure combined with organic fertilizer can be used.
2. Sowing
Use the hole sowing method, placing 4-5 seeds per hole, with about 6000-7000 holes per mu. When sowing, plant at a reasonable density, neither too sparse nor too dense. After sowing, cover with soil promptly, and be careful not to cover too deep. Edamame seeds are relatively large, and after emergence the seedlings have poor ability to push through the soil, so sow relatively shallowly; the best is to cover with about 2 cm of soil. Two days after covering with soil, spray a herbicide once to prevent diseases from threatening seedling growth.
3. Field management
Phosphorus and potassium fertilizers have an obvious yield-increasing effect on edamame, so more phosphorus and potassium fertilizer should be applied. When fertilizing, base fertilizer should be the main part and topdressing supplementary. If phosphorus and potassium fertilizer is insufficient, the plants grow slowly and the leaves show yellowing symptoms. When edamame has grown to a certain extent, it can be pinched back, which not only prevents excessive vegetative growth but also makes it mature earlier and increases yield; pinching is generally done at the flowering stage.
The above is the edamame planting time and methods brought to you by Qinnongwang. Edamame has good disease resistance and generally only suffers from insect pests, so attention should be paid during the planting process.
