Cultivation techniques of four-rowed bean

Four-rowed bean is a perennial herb of Rosaceae, and it is also a famous vegetable in China. Its roots and young pods are edible. Four-rowed beans are rich in protein and fat nutrients, which are widely planted in our country, but it is not easy to grow four-rowed beans, so we need to have certain planting techniques. So how to cultivate four-rowed beans? The following editor brings you the cultivation techniques of four-rowed beans, let's have a look!

1. Deep ploughing and land preparation

Before sowing, we should first select the planting plot, the four-rowed bean has little requirement on the soil, as long as the soil is not too barren, hardened and free of diseases and insect pests. After selecting the planting site, the proper soil preparation is to improve soil permeability, strengthen soil fertility and promote the growth of four-rowed beans. When preparing the soil, it should be turned about 30 centimeters deep, remove the weeds on the land, and apply enough base fertilizer. The base fertilizer is mainly agricultural machinery fertilizer and phosphorus and potassium fertilizer, which is disinfected and exposed to the sun after deep turning, so as to eliminate the bacteria and eggs in the soil and prevent harming the growth of four-rowed beans.

2. Sowing seeds at the right time

Four-rowed beans are extremely hardy, so we have to sow them after the temperature gradually picks up in spring, preferably when the ambient temperature is higher than 20 degrees. Set up the nursery bed one week before sowing, then spread the plastic film, raise the temperature of the nursery bed, and water properly, make the field bed and dig the planting hole after the water gradually seeps. When sowing, put 2-3 seeds in the planting hole, cover fine soil and plastic film after sowing, and keep warm. Before emergence, the temperature of the seedling bed should be kept at about 26 degrees to promote seed germination and emergence.

3. Transplanting and planting

After emergence, the permeability of the field should be enhanced, the temperature of the seedling bed should be controlled at about 23 degrees, and the temperature at night should not be lower than 15 degrees. If the soil is too dry, it should be watered in time, and with the temperature rising, the ventilation rate should be gradually increased. When the average temperature is stable above 16 degrees, remove the plastic film. When the seedlings grow out of 3 true leaves, about a month can be appropriate transplanting, in transplanting to avoid rainy days, the temperature should not be lower than 15 degrees. Transplanting the seedlings with soil and controlling the planting density, the main planting method is ridge cultivation, which can not only ensure the healthy growth of four-rowed bean, but also improve the soil temperature.

4. Field management

The growth rate of four-rowed bean is very slow at the seedling stage, so it is necessary to do a good job in ploughing and weeding regularly to improve the ability of soil moisture conservation. The four-rowed bean is sensitive to nitrogen fertilizer, and less nitrogen fertilizer should be applied during the whole growth period, because the root of the four-rowed bean has a strong ability of nitrogen fixation, excessive nitrogen fertilizer will lead to the growth of four-rowed bean and reduce the flowering and pod setting rate. Four-rowed beans prefer water, so they should be watered regularly to ensure that the soil is moist, prevent the lack of soil water content and affect the growth of four-rowed beans. However, water should not be excessive, and drainage should be done well on rainy days.

The spacing of each plant of four-rowed bean is very large, and the utilization rate of land is low, so we in order to avoid wasting land resources. You can make some low-stem vegetables, such as rape, in the middle of the garden. And the four-rowed bean is a trailing plant, after entering the trailing period, we should do a good job of setting up the frame and introduce the vine on the shelf at the right time.
