Planting methods and management of long beans

Long beans , also known as green beans and string beans , are a common vegetable. It is simple to plant , but some key management techniques are required to obtain a good harvest. Let’s take a brief look at the planting and management methods of long beans.

1. Site selection and land preparation

Long beans prefer a warm and humid environment and are not very demanding on the soil, but it is best to choose well-drained and fertile soil for planting. Before planting, the land should be deeply plowed to loosen the soil, remove weeds and stones, and apply an appropriate amount of organic fertilizer , such as farmyard manure or decomposed chicken manure, to improve soil fertility.

2. Planting time

Beans grown in the open field are usually sown around the Qingming Festival. If managed well, they can continue to grow until the Frost Descent when the seedlings can be pulled out. Greenhouse beans can be planted twice, in spring and autumn. In spring, they are sown in March and the seedlings are pulled out in June and July; in autumn, they are sown in August and September and the seedlings are pulled out around the Spring Festival.

3. Sowing and seedling raising

Select healthy and plump carob seeds and pre-process them. Including soaking, disinfection and germination to improve the germination rate. When sowing, you can use direct sowing or seedling transplanting, and the sowing depth is about 3-5 cm.

4. Moisture management

Since long beans are highly drought-resistant, the water content should be properly controlled before the plants bloom and form pods to prevent the early yields from being affected by excessive plant growth. During the flowering and podding period, the soil should be kept moist to meet the growth needs of long beans.

5. Fertilization points

The base fertilizer is mainly organic fertilizer, and topdressing should be carried out according to the growth of the plant and soil fertility, with an emphasis on applying phosphorus and potassium fertilizers during the flowering and podding period.

6. Build the scaffolding at the right time

Generally, it is necessary to build a rack when the bean seedlings begin to grow and vines appear. The method of building the rack is generally to select three bamboo poles and build them in a triangle. The junction of each pole should be tied with a rope. Finally, use a longer bamboo pole at the top of the pole to connect the top of each triangle, so that the rack can hold more long beans and be more firm.

7. Pest and disease control

Check the plants regularly to detect and treat pests and diseases in a timely manner. A combination of biological and chemical control can be used. Common diseases and pests include rust, powdery mildew, and pod borer.

The above is the sharing of planting methods and management content about long beans. However, in actual operations, management measures must be flexibly adjusted according to local climate conditions, soil types and other factors to obtain the best planting results.
