Detailed Explanation of the Key Technical Points for Early-Maturing Edamame Cultivation and Management
Edamame is divided into two varieties, early-maturing and late-maturing, and early-maturing varieties generally begin sowing in early spring each year. Early-maturing edamame is generally grown using small arched sheds with well-controlled, reasonable planting density, and its economic returns are relatively high. When growing early-maturing edamame, doing a good job of cultivation and management is very important. So today, the editor brings you the key technical points for edamame cultivation and management; let's take a look below!
1. Land preparation and fertilization
Edamame is suited to growing in high-quality soil with sufficient fertility, strong permeability and good drainage. Before planting, first do a good job of land preparation by deep plowing it about 25 cm, fine-tilling and harrowing it carefully to improve soil quality. Try to carry out deep plowing before winter, then deep plow again in spring, and apply sufficient base fertilizer. The amount of base fertilizer used should be large, because the nutritional needs of early-maturing edamame are relatively great, especially its need for phosphorus and potassium fertilizer. The base fertilizer is generally mainly farmyard manure, combined with an appropriate amount of superphosphate. The specific nutrient ratio of the base fertilizer should be determined according to the soil fertility situation; after applying the base fertilizer, shallow plow once more appropriately, and make beds ready for planting.
2. Timely sowing
The sowing method for early-maturing edamame is generally mainly drilling, because early-maturing edamame has strong growth ability. Appropriate close planting can effectively increase yield; control the row spacing at 40 cm and the plant spacing at about 15 cm. Control the sowing amount well according to the soil area, and sowing should not be too deep, keeping it at about 4 cm. Then dig the sowing holes well, and put about 4 seeds into each sowing hole. If missing plants are found, reseed in time to ensure full stands. After sowing, cover with a layer of plastic film, and when the seedlings emerge, do a good job of breaking the film.
3. Thinning and reseeding
Thinning and reseeding are key measures for ensuring the yield of early-maturing edamame. When the seedlings have grown to about 7 cm tall and produced one true leaf, control the plant spacing well and carry out final thinning. Be careful to pull out the overly dense, weak-growing seedlings and keep the robust seedlings. Early-maturing edamame varieties can be kept at a denser spacing, and when thinning, also observe the growth of the seedlings. If missing-plant gaps are found, promptly fill them in with seedlings of the same growth to prevent gaps from forming in the estimated planting number and yield, and ensure a full stand and complete seedling rate.
4. Temperature management
Temperature is also very important for the growth of early-maturing edamame. After sowing, in order to promote seed germination, the temperature should be controlled at about 25 degrees. Increase the emergence rate and ensure a full stand, then during the vigorous growth period of edamame, lower the temperature appropriately to about 22 degrees. Early-maturing edamame has different temperature requirements at each growth stage; for example, 20 degrees is optimal during flower bud differentiation, while during the flowering period it should be controlled at about 26-27 degrees. If the temperature is unsuitable, the impact on its flowering rate is relatively great. So we should also pay attention to doing a good job of ventilation, controlling the day-night temperature difference well, and promoting edamame growth.
The above is a brief introduction to early-maturing edamame cultivation and management techniques. The cultivation and management of early-maturing edamame differs somewhat from the management of ordinary edamame varieties. So everyone should try their best to prepare well for the planting techniques. That is all for today's introduction; this article is for reference only, and we hope it can help you!
