Planting technology of edamame bean in greenhouse

Before planting, prepare the soil and fertilize, dig ditches to make beds. Then sow the local varieties at the right time, cover the soil after sowing, and spray herbicides to control weeds. Then control the temperature in the shed and pay attention to ventilation. Foliar fertilizer should be applied in the flowering stage of edamame, and urea should be applied in the period of falling flowers and pods. Finally, we can do a good job in pest control.

Planting management of edamame bean in greenhouse

1. Temperature management

In the early stage, it is mainly anti-freezing and warm, and in the later stage, ventilation is strengthened. It is required to buckle the greenhouse one week before the live broadcast, and cover the plastic film or arch greenhouse film immediately after broadcast. After emergence, pay attention to choose sunny days and break the membrane in time to release seedlings. The suitable temperature was 15-25 ℃ in the greenhouse before emergence, 20-25 ℃ in the growing period and 20-28 ℃ in the flowering stage. Therefore, according to the growth characteristics of each period, the shed should be closed for warmth or ventilation in time.

two。 Fertilizer and water management

Generally, it is not suitable to apply fertilizer at seedling stage. if the leaves are wrinkled under the influence of low temperature, you can use 50 grams of yellow leaf enemy micro-fertilizer to 30-45 kilograms of water and spray it at noon on a sunny day. Foliar topdressing with 0.5% potassium dihydrogen phosphate aqueous solution during flowering. Spraying time is before 10:00 or after 4 pm, preferably on a cloudy day. Spray once every 7-10 days, and spray once in case of rain after spraying. In addition, in the period of falling flowers and pods, 10 kg urea per mu was applied to water.

In terms of water management, the seedlings should not be watered before they are unearthed after sowing, and the excessive drought in the seedling stage can be watered appropriately to promote root formation. The principle of "dry flowers and wet pods" should be adopted in water management at the fruiting stage of dried flowers.

3. Pest control

Edamame beans in the greenhouse are easy to cause dead seedlings because of the low temperature and humidity in the greenhouse at the seedling stage and the application of immature farm manure. Therefore, 200 grams of chlorothalonil smoke remover per mu can be selected for chemical control in the seedling shed, and water agents should be used as little as possible. When the edamame bean is in 4 leaves, it can be sprayed with chlorothalonil, carbendazim and other agents. Spray once every other week for a total of two times.

Generally, edamame beans planted in greenhouse enter the harvest period from April to May and can be harvested in batches. Go on the market as soon as possible after harvest in order to obtain higher benefit.
