High-yield Cultivation and Management Techniques of Green Beans in Early Winter
Broad bean is rich in nutrients and has a wide range of uses, suitable for processing a variety of foods. Broad bean has high protein content and complete amino acids. As a source of plant protein, it has received increasing attention. Planting green food broad beans for sale, early and high efficiency, and the green food broad bean skin is thin and fresh, the meat is fine and delicate, the texture is soft, the taste is sweet and crisp, the taste is good, and the nutrition is rich. It is a seasonal dish in the late spring and early summer vegetables. It can be used as a side dish or a famous dish. No matter the habit of eating green beans in both urban and rural areas, it is favored by consumers in large and medium-sized cities. It is a seasoned vegetable. In recent years, the Agricultural Bureau of Gucheng District of Lijiang City has made full use of the local three-dimensional climate resources to vigorously develop winter and early green beans, and has planted broad beans in Jinan Town, Qihe Town, Dadong Township and Jinjiang Township of Gucheng District. The rapid development of the green food broad bean industry has increased farmers' income. Its cultivation management techniques are as follows:
First, choose a good species
The choice of green food broad bean planting varieties should be large and large pods, good commodity, early flowering and fast drums. It takes only about three months from sowing to collecting green bean pods. It has strong disease resistance, strong resistance and good quality. Adapted to the cultivation season, the early-maturing broad bean varieties with good taste are Yundou 147, Yundou 95-34, Yundou 399 and so on.
Second, timely seeding
Broad bean is a deep root crop. Fine soil preparation before sowing can make the soil soft, which is conducive to the expansion of root system and the formation of nodule. The seed amount per mu is 10-15 kg, and seed dressing is carried out with Rhizobium before sowing. Early-season green beans are promoted to ridge seed beans, suitable for sowing, dry land such as flue-cured tobacco and corn can be sown in mid-September. Rice husk stalks can be sown in early and mid-October, adding organic fertilizer and demonstrating application of refined organic Fertilizer new technology, according to one meter to open the ridge, 0.5 m wide, 0.5 m ridge, 1500-2000 kg of organic fertilizer as the base fertilizer when ridges. Demonstrate “Dajiabao†brand refined organic fertilizer, apply 300kg per mus to the ridge once a ridge to reduce the application of inorganic fertilizer.
Third, scientific management
1. Scientific water: Broad beans should be wet and should not be properly drained. Keep the soil moist in the early stage of growth, which is conducive to seed germination and rooting. The soil in the middle growth period is dry, which is good for roots deep, more lateral roots, thick stems and leaves;
2. Promote soil testing and formula fertilization, organic molybdenum seed dressing and spraying new technology, green food broad bean has a short growing period and less branching, so it is necessary to fertilize early, promote branching early fast hair and flower bud differentiation, increase the number of pods, so Focusing on the fertilization technology of broad bean soil testing based on “reducing phosphorus, increasing potassium and filling up the deficiencyâ€, the application of calcium is 30-35 kg per mu and 8-10 kg of potassium sulfate. Before planting, 10 kg of organic molybdenum 50 g was sown, and sprayed with 150 g of organic molybdenum 50-60 kg in the initial flowering period of the broad bean to solve the molybdenum deficiency moth disease. By strengthening the application of potassium fertilizer and supplementing the micro-fertilizer, the knot was improved. The pod rate promotes the fullness of the grain to improve the yield and quality of the product.
3. Intercropping and weeding: When the emergence of broad bean is 5-6 leaves, timely cultivating, improving soil water, fertilizer, gas and heat, promoting root growth and branching, and clearing weeds in the field. The broad bean is in the beginning of the bud, and the sunny day is selected, and the artificial weeding is repeated again to improve the ventilation and light transmission conditions and increase the pod formation rate.
Fourth, pest control
1. Diseases are mainly based on broad bean rust. It is mainly based on prevention and prevention in advance. The soil can be disinfected with carbendazim 200g/mu, and the soil is sown for about 2 days. Preventing from the beginning of the seedling stage can be prevented by spraying the powder rust 300g/mu three times at intervals of 10 days. Budding blight can be controlled by chlorpyrifos, and root rot is generally prevented by agricultural streptomycin.
2. Pest control is mainly done at any time. If it is found that there are pests in the field or in the surrounding fields, it is necessary to spray the drugs in time. Bean flies and mites can be controlled by lesbian, dimethoate and kungfu.
Fifth, timely harvest
Harvest at the right time, harvest green beans and broad beans for vegetables, and after the end of the broad bean granules, harvest them in batches, and harvest a pod with a pod to ensure the commerciality of the pods to ensure their economic benefits.
