Broad bean contains phytohemagglutinin protein, which can adhere to the surface of cancer cells and inhibit the growth of cancer cells. Phospholipids contained in broad beans are a component of nerve tissue. Choline is an indispensable chemical component for nerve cells to transmit information. Broad beans can enhance brain memory and strengthen the brain. Moreover, broad beans are not only nutritious, but also have various eating methods, so they are welcomed by the market. So how to plant it?
1, cultivation period
Broad beans are usually planted in spring or autumn. Spring is from the middle and late March to the beginning of April, and autumn is from1early October to 1 1 early October. Timely planting helps to keep the seedlings together. In early autumn, it is not suitable to cultivate dry broad beans with neat and strong seedlings, so as to prevent the cold injury of broad beans when they bloom.
2. Seed selection
Cultivating high-yield, disease-free and high-quality seeds is conducive to softening the soil in cultivated land before sowing, swelling and germination of rhizomes in a large area to form nodules, and using rhizobia inoculation to improve yield. You can choose the method of soil inoculation, dig about 50 kilometers of soil in the place where broad beans are planted, and scatter it in the ditch when sowing.
3. Planting conditions
The temperature requirement of broad bean varies with the growth period. The suitable temperature for seed germination is16 ~ 25℃, the lowest temperature is 3 ~ 4℃, and the highest temperature is 30 ~ 35℃. The temperature needed in vegetative growth period is relatively low, with the lowest temperature 14~ 16℃ and the temperature needed in flower and fruit period 16~22℃. Under the low temperature of 0 ~4℃, the above-ground parts will suffer from freezing damage. Although Vicia faba can fix nitrogen in the air by rhizobia, its growth still needs to absorb a lot of various elements from the soil. Due to the lack of elements, various physiological diseases often occur.
4, seedling management
After sowing, cover with soil and straw to keep the temperature and humidity. In the process of growth, the diseased plants are treated, and the diseased bodies and weeds are removed and destroyed in a centralized way. Spraying pesticides to control pests and rodents, controlling water, and tidying branches and seedlings. Ensure the normal development of plants. In the later stage, ensure the water demand of plants, control the density, and keep the ground ventilated and light-permeable.
5, fertilization and watering
After sowing, it should be watered in time to maintain the required water and promote the early germination and emergence of seeds. After sowing, the soil should be compacted to prevent the planted plants from lodging. When young leaves grow, appropriate amount of nitrogen fertilizer should be applied, and phosphorus and potassium fertilizer should be applied at different times during the growth period. More trace elements should be applied during pod setting to reduce the loss of flowers and pods and achieve high yield. At the initial stage, drainage and ventilation are mainly ensured to avoid falling flowers, pods and dried beans.
6, intercropping pruning
Check in time after emergence, and replant immediately if missing seedlings are found. At seedling stage, it is necessary to plough and weed frequently, compact and thicken the soil to prevent lodging.
