How to grow long kidney beans? Cowpea high-yield planting technology
How to grow long kidney beans? Kidney beans can also be called long beans, beans, carob, rice beans, kidney beans, beans, skirt beans, chopsticks beans, is one of the common vegetables on our table, can be fried, cold, salted, and can Processing kimchi and drying beans, the following small series will simply talk about the high-yield planting techniques of cowpea, I hope to help everyone. First, the growth and development characteristics of cowpea The somatic development of cowpea, in terms of vine species, can be divided into four periods, seed germination, seedling, vine and flowering pods from seeding to pod ripening or seed maturity. 1. Seed germination period Cotyledons are unearthed, no photosynthesis is used, and storage nutrients are decomposed and used during germination. Later, photosynthesis will be carried out and living independently. 2, seedling stage The first pair of true leaves are carried out until 7-8 compound leaves are in the seedling stage; The seedling period is short, the stem is erect, and the root system is gradually developed. 3, the pumping period There are 7-8 compound leaves to the buds of the plants. During this period, the main vines rapidly elongate and the nodules begin to form. 4, flowering pod stage After the plant is budded until the end of harvesting of the pod or the maturity of the seed, it is often 50-60 days, depending on the variety and cultivation season. Second, the cultivation environment of cowpea 1, temperature Germination temperature: 25-35 degrees; Growth and development temperature: 20-25 degrees; Temperature > 35 degrees < less than 15 degrees, growth pods are affected; When it is close to 0 °C, the plants will suffer from freezing damage. 2, lighting Short days can accelerate the growth and development of cowpeas, early maturity, and when the light is insufficient, it will cause the flowers to fall. 3, moisture Excessive soil moisture → decreased germination rate, dead roots, dead flowers and fallen pods; Insufficient soil moisture → inhibit the growth and development of cowpea and reduce yield. 4. Soil Soil with good drainage performance, loose and fertile soil and soil pH of pH 6.2-7. 5, fertilization Appropriate application of nitrogen fertilizer. Third, the cultivation technology of cowpea 1, improved seed selection Commonly used varieties are the 豇 series, Yang 豇 series, Nanjing star series, Yan belt 七, seven inch 豇, eight inch 豇, 豇 豇 beans. 2. Cultivation season and sowing date Early spring cowpea: In the 3-4 months, seedlings can be planted in greenhouses and other facilities. After mid-April, the film can be broadcast live, and the ground can be broadcast live from the end of April to the beginning of May; Spring and summer cowpeas are planted in mid-July; Autumn kidney beans are planted from July to early August. 3, soil preparation and application of base fertilizer Avoid continuous cropping, need to rotate for more than two years; After harvesting, 20-30cm deep ploughing, 3000kg of base fertilizer per acre, 25-30kg of superphosphate, 50-75kg of ash or ash, or 10-20kg of potassium sulphate. 4, reasonable close planting Early spring cowpea should be planted when the first pair of true leaves has not yet been unfolded; Planting should master the principle of planting small plants and planting droughts; Planting two plants per hole when planting; Summer and autumn kidney beans are mostly used for live broadcast, and the seeding rate per hole is 3-4 or 4-5; The seeding density row spacing is 0.8-1m, and the plant spacing is 0.26-0.33m. 4. Field management of cowpea cultivation 1. Field management of cowpea cultivation Mainly include: fertilizer and water management, plant adjustment, establishment of stents, temperature and water management, pruning and topping, harvesting and so on. 2. Pest control Locust: Spray with 40% dimethoate every 7-10 days; Bean wild donkey: 800 times of dichlorvos in the cowpea flowering period, spray once every 6-10 days; Kidney bean coal mold: spray 2-3 with 50% carbendazim 1000 times solution or 50% thiophanate 1000 times solution; Cowpea rust: Spray with 70% methyl thiophanate WP 1000 times or 65% sensitized zinc 500 times solution, spray once every 7-10 days, and spray 2-3 times continuously. Freeze-dried powder is a sterile powder injection obtained by freezing the liquid medicine into a solid state in a sterile environment, and subliming and drying the water in a vacuum. Freeze-dried powder is composed of a bottle of high-purity and high-active biological protein freeze-dried powder and a high-purity liquid essence. When using, it needs to be connected with a patented vacuum to reconstitute the freeze-dried powder and the essence to activate the biological protein activity.
