What kinds of beans are there?

Beans are common vegetables in our life, such as cowpea, sword bean, lentil, pea, etc. Among them, the planting area of long beans ranks first among these varieties.

One: What are the kinds of beans?

Cowpea: Cowpea friends have a lot of things they don't understand, which is what we call long beans. Lentils: Lentils are also very rich in nutritional value and are often eaten in summer and autumn. Kidney beans: tender kidney beans are used for cooking or pickles, which are not only delicious, but also have the effect of warming up; Concanavalin has a good therapeutic effect on hiccups. Peas: Peas. Two: How to grow beans

1. Variety selection: 8 10 Long bean, Ningxiang No.2 and Xiabao No.2. Soil preparation and fertilization. Beans have deep roots and are resistant to poor soil and drought, but not to waterlogging. In order to achieve early maturity and high yield, we should choose soil with deep soil layer, convenient irrigation and drainage, and not extremely dry, and make planting rows with box width 1 m, ditch width 0.4 m and depth 0.3 m, and apply organic fertilizer 1000-2000 kg, calcium superphosphate 40 kg, urea 25 kg or ternary compound fertilizer 40 kg as base fertilizer per mu. 3. sow. Sowing quality directly affects seed germination and seedling quality. Improving sowing quality can ensure vigorous whole seedling and promote early maturity and yield increase. Generally, hole sowing is adopted, with 2-3 capsules per hole. After sowing, cover the seeds with fine fertilizer, the thickness is 1-2cm, the spacing between plants is 0.4 m in spring and 0.35 cm in summer and autumn. Double row planting is adopted. 4, rational fertilization, to prevent the seedling growth, to prevent premature aging. Beans don't need too much fertilizer before flowering and pod setting, so fertilizer and water should be properly controlled in the early stage to inhibit the vegetative growth of plants. If the seedling growth is too weak, biogas slurry and urea can be diluted 1-2 times. Beans consume a lot of nutrients during flowering and pod setting, so they need high water and fertilizer. Therefore, we should give them enough water and apply heavy fertilizer in time. 30 kg of compound fertilizer, 65,438+00 kg of calcium superphosphate and 5 kg of potassium chloride can be topdressing per mu, and potassium dihydrogen phosphate is sprayed 65,438+0-2 times a week, and borax is added to promote the vigorous growth of plants. After the vigorous growth period of pods, more fertilizer should be applied, and phosphate fertilizer 1 time, calcium superphosphate 10 kg, or calcium superphosphate leaching solution should be applied per mu to reduce flower and pod dropping. After the full pod period, if the plant can continue to grow, we should strengthen the management of fertilizer and water, promote the germination of lateral branches, promote flowering, and make the flower buds on the harvested inflorescences continue to bloom and bear pods, thus prolonging the harvest period of cowpea and improving the yield of cowpea. 5. Support the vine. When the seedlings begin to draw vines, they should set up a bracket, insert a bamboo pole into each hole and set up a herringbone frame. The bracket is 2 meters high. When the rattan is 0.3 meters long, the bean rattan should be wrapped around the bamboo pole counterclockwise. Step 6 trim. Pruning is an effective measure to adjust the growth and fruit of beans, reduce nutrient consumption, improve ventilation and light transmission, and promote flowering and pod setting, especially in the case of early maturity and close planting, to prevent the stems and leaves from being too lush, which is conducive to early flowering and pod setting and early harvest. Pruning includes wiping the bottom bud, punching the waist fork, picking the main rattan core and picking the old leaves. When the lateral buds under the inflorescence under the main vine grow to about 3 cm, they should be all removed as soon as possible to make the main vine strong and promote the flowering and pod setting of the main vine. 1-3 leaves remain on the lateral branches below the main vine and above the inflorescence, and the inflorescence on the lateral branches remains to increase the pod setting position. After the first yield peak, the 1-3 nodes of new lateral branches between leaf axils were also reserved for coring, and the number of leaves left depended on the density. When the main vine grows to 15-20 knots and reaches 2-2.3 meters, it is capped to control the plant height. Leave a leaf on the sprouting side branch at the top to pick the core, and the beans will grow to the peak. If the ventilation and light transmission at the bottom are not good, it is easy to cause falling flowers and pods in the later stage. You can cut off the old leaves at the lower part and get rid of the fallen leaves in the field.
