Do you know the efficacy and function of fish protein fertilizer?

1. Fish protein fertilizer is a natural functional fertilizer, which can be used as base fertilizer, topdressing, root irrigation, drip irrigation, flushing, and leaf spray. The main function is to increase the content of soil organic matter, promote the reproduction of soil microorganisms, activate soil nutrients, improve the ability of soil to maintain fertilizer and water, and increase soil fertility.
2. Fish protein fertilizer can promote root system development, plant growth, photosynthesis, flower bud differentiation, early maturity and quality improvement. When sprayed on fruit trees, the disease will be reduced, the leaves will be green and shiny, the number of fallen flowers and fruits will be reduced, the yield is high, the taste is good, the color is bright, the fruit type is good, the quality of melons and vegetables is good, the color is bright, and it is a pollution-free green nutrient fertilizer.
3. In the early stage of virus disease in pepper, tomato and other crops, the use of fish protein foliar fertilizer combined with virus killing pesticides can alleviate the symptoms of leaf streak, shrinkage, mosaic and other symptoms caused by virus disease; For greenhouse cucumbers planted over the winter in northern China, fish protein is sprayed once before and after flowering and planting, which can significantly reduce the yield reduction and poor growth caused by cold wave and haze, and improve the fruit quality. In case of fertilizer damage and drug damage to vegetables in the open air, which may cause stiff seedlings, amino acid containing fertilizers such as fish protein can be sprayed and flushed in time to restore the growth of plants as soon as possible and alleviate the poor growth. Spraying fish protein foliar fertilizer once 10 days before flower picking can prolong the flowering period, which is helpful for flower preservation and transportation;
4. Spraying fish protein fertilizer once at the early flowering stage and early fruiting stage of watermelon can significantly increase the yield and sugar content; Spraying fish protein fertilizer on the leaves of cotton once at the boll setting stage, budding stage and before picking can promote the growth of cotton, which is mainly manifested in the increase of boll number per plant, cotton plant, yield and single boll weight. Applying fish protein fertilizer 3 times in time during the growth period of cabbage can promote the growth and development of cabbage and increase the yield;
When choosing fish protein, try to choose fish protein produced by enzymatic hydrolysis process. It is easier to be absorbed by crops with small molecular weight!
