There are late-maturing varieties and early-maturing varieties of edamame. Early-maturing varieties of edamames are generally sown in early spring each year, but many friends don't know what are the main points of the cultivation of early-maturing edamames. Let ’s learn a few together.

Land preparation

Edamame is suitable for growing on high-quality soils with sufficient fertility, strong permeability, and good drainage. Before planting, we must do a good job of preparing the land, ploughing it for about 25 centimeters deep, finely raking it, and improving the quality of the soil. Try to deepen it before entering winter, and then plough it again in spring, and apply sufficient base fertilizer.

2. Base fertilizer

The amount of base fertilizer should be more, because the nutritional requirements of premature edamame are relatively large, especially for phosphorus and potassium fertilizers. The base fertilizer is generally based on farm manure, with a suitable amount of superphosphate. The specific nutrient ratio of the bottom fertilizer should be determined according to the soil fertility. After the bottom fertilizer is applied, it should be shallowly plowed again and prepared for planting.

3. Timely sowing

Sowing methods of premature edamame are generally based on seeding, because the growth ability of premature edamames is strong. Proper dense planting can effectively increase yield, control row spacing at 40 cm, and plant spacing at about 15 cm. Control the seeding amount according to the soil area. The seeding should not be too deep. Keep it at about 4 cm. Then dig seeding holes, and put about 4 seeds in each seeding hole. If there is a lack of trees, timely replanting is required to ensure Qimiao. After sowing, a layer of mulch should be covered, and when the seedlings are unearthed, do the film breaking work.

4. Temperature management

Temperature is also very important for the growth of premature edamame. After sowing, in order to promote seed germination, the temperature should be controlled at about 25 degrees. Increase the emergence rate, ensure that the seedlings are uniform, and then reduce the temperature to about 22 degrees during the peak growth period of edamame. Early growing soybeans have different temperature requirements during each growth period. For example, 20 degrees is the best when the flower buds are differentiated, and the flowering period should be controlled at about 26-27 degrees. If the temperature is not suitable, the effect on its flowering rate is relatively large. . Therefore, we must also pay attention to ventilation work, control the temperature difference between day and night, and promote the growth of edamame.

5. Thinning seedlings

Thinning seedlings is a key measure to ensure the yield of early-maturing edamame. When the seedlings grow about 7 cm in height and grow a true leaf, the plant spacing should be controlled for seedling setting. Attention should be paid to removing overgrown and weak seedlings and retaining strong seedlings. Early maturing varieties of edamame leaves can be kept dense, and the growth of the seedlings should be observed when thinning. If it is found that there is a lack of seedlings, it is necessary to supplement the seedlings of the same growth in time to prevent the gap from the estimated planting quantity and yield, and to ensure the rate of the whole seedlings.
