Planting time and method of long bean

The planting time of long bean is from February to March in spring, from May to August in summer and from August to October in autumn. Planting method of long bean: choose fertile soil to plant, sprinkle appropriate amount of fertilizer during soil preparation, sow seeds by hole sowing and sowing, reasonably water and promote new roots before flowering, set up a frame when seedlings grow to 30cm or so, fertilize in time during flowering, pay attention to control pests such as bean pod borer, cowpea pod borer, and prevent root rot.

1. Long planting time for beans

1. If long beans are planted in the greenhouse, they can be planted all the year round, and the sowing time can be arranged reasonably according to the climate temperature of different areas before planting.

2. Sowing is usually from February to March in spring, from May to August in summer and from August to October in autumn.

2. Planting methods of long beans

1. Land selection and fertilization

The main results are as follows: (1) long bean has a strong ability to adapt to the environment, and any soil can be planted. If you want to have a high yield, you should choose a more fertile soil.

(2) prepare the soil after selecting the planting site and dig deeper as far as possible. In order to ensure soil fertility, appropriate amount of fertilizer can be applied during soil preparation.

2. Sowing method

There are two sowing methods of long bean: hole sowing and sowing.

(1) hole sowing: on the whole land, dig holes according to a certain interval, each hole can sprinkle about 3-5 seeds, and cover the soil after applying fertilizer around. Pay attention to the fertilizer must not touch the seeds during fertilization, so as to avoid burning seeds, so as to reduce the emergence rate.

(2) sowing: choose a piece of seedling land, sow the seeds into the soil, and then cover a layer of film, wait for the seeds to germinate, remove the film, properly water, wait until the seedlings grow to 5-6 cm, you can pull up the seedlings, reasonable planting, if there is no rain after planting, otherwise the seedlings will die.

3. Post-management

The main results are as follows: (1) long beans need to be watered reasonably before flowering, especially the transplanted seedlings, which is beneficial to the growth of new roots.

(2) Bean seedlings are crawling, and generally need to be set up when the seedlings grow to about 30cm, which is not only beneficial to increase the yield, but also convenient for picking in the later stage.

(3) topdressing must be carried out in time during the flowering period of long beans, which is beneficial to increase the pod setting rate of beans and thus increase the yield of beans.

4. Prevention of diseases

The main pests of beans are bean pod borer, cowpea pod borer and so on. The incidence of bean is relatively low, and root rot occurs occasionally. If the disease is found in the process of planting beans, it must be treated in time, and targeted agents can be selected for prevention and treatment.
