The Latest Cultivation and Management Techniques and Methods Tutorial for Early-Maturing Edamame
Edamame is divided into two varieties, early-maturing and late-maturing, and early-maturing varieties generally begin to be sown in early spring each year. Early-maturing edamame is generally grown using small arch tunnels with well-controlled, reasonable density, and its economic returns are relatively high. When growing early-maturing edamame, doing a good job of cultivation and management work is very important. So today, the editor has brought you the key points of edamame cultivation and management techniques. Let's take a look below!
1. Land preparation and fertilization
Edamame is suitable for growing in high-quality soil with sufficient fertility, strong permeability and good drainage. Before planting, the land preparation work must first be done well, deep plowing it about 25 cm, and finely leveling and harrowing it to improve soil quality. As far as possible, carry out deep plowing before winter sets in, then deep plow once more 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 conditions. After applying the base fertilizer, carry out one more appropriate shallow plowing, and make beds ready for planting.
2. Sowing at the right time
⟦NL>The sowing method for early-maturing edamame is generally mainly drilling, because early-maturing edamame has relatively 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 according to the soil area, and sowing should not be too deep; keeping it at about 4 cm is enough. Then dig the sowing holes well, and put about 4 seeds in each sowing hole. If missing plants are found, replant in time to ensure a full stand of seedlings. After sowing, cover with a layer of plastic film, and when the seedlings emerge, do the work of breaking the film.
3. Thinning and filling in seedlings
Thinning and filling in seedlings are key measures to ensure the yield of early-maturing edamame. When the seedlings grow to about 7 cm tall and have produced one true leaf, control the plant spacing well and carry out the final thinning work. Pay attention to pulling out the weak seedlings that are growing too densely, and keep the robust seedlings. Early-maturing varieties of edamame can keep a denser stand of seedlings, and when thinning, also observe the growth of the seedlings. If missing planting holes are found, promptly fill them with seedlings of the same growth to prevent a gap from arising with the estimated planting number and yield, and ensure the rate of a full and even stand of seedlings.
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 an even stand of seedlings, 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, during flower bud differentiation, 20 degrees is best, 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 good ventilation work and controlling the day-night temperature difference well to promote edamame growth.
The above is a brief introduction to the cultivation and management techniques for early-maturing edamame. The cultivation and management of early-maturing edamame differs somewhat from the management of ordinary varieties of edamame. So everyone should do their best to prepare well for the planting techniques. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
