In addition to being a pure natural fertilizer, fish protein organic liquid fertilizer is abundant in organic matter, fish protein, peptides, biological polysaccharides, and other beneficial components. It is also a kind of functional fertilizer, which means that it may be used as a base fertilizer, as a topdressing, and as an irrigated root, drip irrigation, or flushing spray. After plowing the soil, fish protein fertilizer with a high concentration of organic matter, protein, polypeptides, and other components can significantly increase the amount of organic matter in the soil, which can rapidly promote the breeding of soil microbes, greatly activate the soil’s nutrients, increase the soil’s fertility, and improve the soil’s ability to protect itself from fertilizer. It is possible to efficiently solve soil hardening issues and preserve soil fertility through the use of fish protein fertilizer, which has the potential to retain water. By using fish protein, you may encourage the development of roots, enhance photosynthesis, encourage the growth of plants, and be advantageous to the differentiation of flower buds. Additionally, fish protein can mature early and significantly improve the quality of the product. the spraying of fruit trees, the green glow of the leaves, the reduction of illness, the enhancement of the quality and quantity of fruits and vegetables, and the use of fish protein fertilizer, which is an environmentally benign and pollution-free green fertilizer nutrient. Additionally, fish protein fertilizer has a very excellent inhibitory impact on plant diseases and insect pests, and it may be used in the following ways: Growing robust seedlings and fostering the potential of plants are both important. Additional information on fish protein fertilizer a particular use of fish protein in agricultural production When tomatoes are in their early stages, spraying them with fish protein helps to stimulate leaf hypertrophy, grow roots, and enhance seedling adaptability. When the plant is in the bud stage, fish protein may help minimize deformed blooms and boost the fruiting rate. It is possible to lengthen the harvesting period by using fish protein twice, ensuring that the size of the fruit is consistent, increasing the weight of a single fruit, and increasing the intensity of photosynthesis. strawberry after transplanting, with fish protein, moderate seedling pace, and strong root formation and growth. Enhancing the sugar content of the fruit and increasing the production may be accomplished by early blooming and spraying with fish protein. 3. spray grapes before to germination in order to avoid the cold spring from occurring. After the seeds have germinated, spraying fish protein that is at least 1500 times thinner may hasten the development process and increase the plant’s tolerance to adverse weather conditions. Immediately after the fruiting stage, spray fish protein three times to stimulate photosynthesis, enhance the sugar content of the grapes, raise the weight of a single ear, and enhance the plant’s tolerance to stress. In the case of watermelon, the application of fish protein at the seedling stage results in the development of roots, the development of robust stems, the slowing of seedling speed, the reduction of the incidence of viral infections, and the improvement of crop stress tolerance. The melon should be sprayed with fish protein two to three times, at intervals of seven to fourteen days, in order to boost photosynthesis, improve yield, and raise the amount of sugar present. 5.chili after transplanting: spray 1500-2000 times of fish protein, spray 2-3 times, every interval of 7-15 days, enhance disease resistance, prevent dropping flowers and fruits, lengthen the harvest season, mature living culm, raise the quantity of pepper, improve the quality of pepper.
