Cultivation and management techniques of early maturing edamame bean

Edamame beans are divided into early-maturing and late-maturing varieties, and early-maturing varieties generally begin to sow in early spring every year. Early maturing edamame beans are generally planted in small arched sheds and controlled density, and their economic benefits are still relatively high. When planting precocious edamame beans, it is very important to do a good job of cultivation and management. So the editor brings you the key points of cultivation and management techniques of edamame bean today. Let's take a look at it.

1. Soil preparation and fertilization

Edamame is suitable for growing on high-quality soil with sufficient fertility, strong permeability, good drainage and so on. Before planting, we should first do a good job of soil preparation, ploughing about 25 centimeters, fine rake, to improve the quality of the soil. Try to dig it deep before winter, and then plough it again in the spring, and apply sufficient base fertilizer. The amount of base fertilizer should be more, because the nutritional demand of early-maturing edamame beans is relatively large, especially the demand for phosphorus and potassium fertilizer. Base fertilizer is generally based on farm fertilizer, combined with an appropriate amount of calcium superphosphate. The specific nutrient ratio of the base fertilizer should be determined according to the soil fertility. After applying the base fertilizer, the soil should be ploughed once and the bed should be prepared for planting.

2. Sowing seeds at the right time

The sowing method of precocious edamame is generally strip sowing, because the growth ability of precocious edamame is strong. Proper close planting can effectively increase the yield, controlling the row spacing at 40 cm and the plant spacing at about 15 cm. According to the soil area to control the sowing rate, sowing should not be too deep, keep at about 4 cm. Then dig the sowing hole and put about 4 seeds in each hole. If it is found that there is a lack of trees, it is necessary to replant in time to ensure that the seedlings are complete. Cover a layer of plastic film after sowing, and break the film when the seedlings are unearthed.

3. Replenish seedlings with inter-seedlings

Replenishing seedlings is the key measure to ensure the yield of precocious edamame. When the seedlings grow about 7 cm high and grow a true leaf, it is necessary to control the plant distance to fix the seedlings. Attention should be paid to pulling out the weak seedlings that are too dense and keeping the strong seedlings. The seedlings of early-maturing varieties of edamame can be dense, and the growth of seedlings should be observed during the seedlings. If it is found that there is a lack of seedling holes, it is necessary to make up the seedlings with the same growth in time to prevent the gap with the estimated planting quantity and yield, so as to ensure the whole seedling rate.

4. Temperature management

Temperature is also very important for the growth of precocious edamame. After sowing, in order to promote seed germination, the temperature should be controlled at about 25 degrees. Increase the emergence rate, ensure full seedling, and then reduce the temperature to about 22 degrees during the peak growth period of edamame beans. Early maturing edamame beans have different temperature requirements in each growing period, for example, 20 degrees is the best during flower bud differentiation, and the flowering period should be controlled at about 26-27 degrees. If the temperature is uncomfortable, it will have a greater impact on its flowering rate. Therefore, we should also pay attention to ventilation, control the temperature difference between day and night, and promote the growth of edamame beans.

The above is a brief introduction of the cultivation and management techniques of precocious edamame. The cultivation and management of precocious edamame is different from that of common varieties. Therefore, we should try our best to prepare for the planting technology. That's all for today's introduction. This article is for reference only. I hope it can help you all.
