Beans are hi fat but not fat, water and fertilizer management mainly includes three aspects: Shizujifei, timely top dressing; increased application of phosphorus and potassium fertilizer, appropriate amount of nitrogen fertilizer; first controlled and promoted to prevent leggy and premature aging.
Bean plant nutrition is the key to increasing inflorescence and pod formation. Excessive basal fertilizer can promote the growth of roots and rhizobia, forming more root nodules, making the early stem vines grow robustly, and differentiate more flower buds, laying the foundation for high yields. Basal fertilizer generally applies 2000-3000 kg of organic fertilizer per mu, 25-30 kg of superphosphate and 50 kg of plant ash.
Before the flowering and scabbing of the bean, the requirement of water and fertilizer is not high, and the management is mainly controlled. The basal fertilizer is adequate, and it is generally no longer top-dressing. When the weather is dry, it can be properly watered. If there are too many water and fertilizers, the stems and leaves will be lengthy, causing the inflorescence to rise and the number to decrease. It is easy to form the middle and lower parts of the sky. When the plant's first inflorescence pods are sitting, the following inflorescences appear to be combined with topdressing to pour water once, applying 10-15 kg of compound fertilizer per acre, and irrigation of 20-30 cubic meters.
After scabs, keep the soil moist and apply topdressing once every 1-2 weeks to keep the plants robust and flowering. Into the harvest period of soybean meal, the need for more water and fertilizer, can be followed by 1 irrigation fertilizer, 10 kg of urea per mu, 20-25 kg of superphosphate, 5 kg of potassium sulfate or 40 kg of plant ash, 20-30 cubic meters of irrigation water Meter. If the supply of water and fertilizers is insufficient, the plants are prone to growth and decline, resulting in falling flowers.
Plant extracts refer to substances extracted or processed from plants (all or a part of plants) using appropriate solvents or methods. They can be used in the pharmaceutical industry, food industry, health industry, beauty industry and other industries.
Plant extracts are based on plants as raw materials. According to the needs of the use of the final product extracted, through physical and chemical extraction and separation processes, one or more effective ingredients in the plant are obtained and concentrated without changing the effective ingredients. The product formed by the structure. According to the different components of the extracted plants, glycosides, acids, polyphenols, polysaccharides, terpenoids, flavonoids, alkaloids, etc. Are formed; according to different properties, they can be divided into vegetable oils, extracts, powders,crystalline powder, etc.
