Dutch beans can be planted all year round in the south. When cultivated in the open air in autumn, it can be planted after the end of August. If it is planted in greenhouse in winter, it can be planted after 5438+ 10 in June, and it can be planted in the open air in February-April in spring. Cultivation can be carried out in May in summer, and the erection time of sunshade net can be postponed.

When planting Dutch beans, you need to master the technical points:

illuminate

Lighting conditions are essential. Dutch beans need a lot of light when they grow. No matter what variety, only long-term exposure to sunlight can lead to early flowering, and if there is no illumination, the flowering time will also be inhibited. In order to improve the yield and quality, it is necessary to provide sufficient light, especially in the late stage of pod setting.

2. Land

Dutch beans have strong adaptability to soil, and both sandy soil and clay soil can grow normally, but if you want to get higher quality, you'd better pay attention to the organic content of soil. Among them, the soil ph value has a great influence on it.

Step 3: Moisture

After the seedlings grow, the demand for water decreases, but when flowering, there is a certain requirement for air humidity. If the pod does not replenish water in time when it grows, it will promote its early maturity.

4. Pests and diseases

Powdery mildew and mildew often occur, so the seeds should be disinfected before sowing and controlled with drugs after sowing. If the virus is found, it should be pulled out immediately and taken out of the site for destruction to prevent infection.

5. Tian Tuan management

Daily management should pay attention to the hygiene and temperature and humidity in the field, and pull out weeds around crops in time. It needs to be harvested in time in the future, because the growing season and planting methods adopted in different places are different, so there is no fixed harvesting time. Sometimes sowing in summer, because of high temperature and fast growth, can be harvested quickly, generally as long as the pods are bulging.
