Zinc fertilizer for rice, disease resistance, high yield and health

In recent years, due to the lack of fertilization technology, one-sided pursuit of nitrogen, phosphorus and potassium nutrients, ignoring the role of trace elements, rice nutrition is not comprehensive, rice physiological diseases occur from time to time. This has become one of the main limiting factors affecting the yield of rice. Zinc is the manager of nutrients, which can coordinate the distribution of nutrient elements in crops, distribute nitrogen, phosphorus and potassium to the parts needed by crops, participate in crop respiration, and enhance crop retrograde resistance, especially freeze resistance, cold resistance and high temperature resistance. promote the formation of pistils. Proper zinc supplementation not only has many benefits to plants, but also plays a very important role in human nutrition and health. By increasing the zinc content of agricultural products, it is helpful to adjust the nutritional balance of zinc in the food chain and promote human health. According to scientific research, zinc is one of the important trace elements necessary for the growth, development, nutrition and biochemical metabolism of organisms. Reasonable intake of zinc has seven benefits: promoting the intellectual development of children, accelerating the growth and development of adolescents, maintaining and promoting the development of eyesight, affecting taste and appetite, promoting the development of sexual organs, preventing Alzheimer's disease and improving immunity. Zinc is not only a mentor to enhance intellectual development, but also a contribution to human bodybuilding. Therefore, it is necessary to supplement zinc and increase zinc for both plants and human beings. Zinc deficiency was obvious in three stages of rice growth, namely, seedling stage, transplanting stage and booting stage. There are many methods of zinc application to rice, and the appropriate method can be selected according to the specific conditions in practical operation. 1. Field bottom application: 200g Hefeng granule zinc or Futawei Wuhe zinc as base fertilizer per mu can improve rice quality and yield. two。 Zinc application in seedling bed: the seedling bed was sprayed with 2000 times of Hefeng zinc or Fenglihui zinc solution the day before transplanting. 3. Rice slow seedling to return to green stage: the combined application of phosphorus and zinc fertilizer can promote the absorption capacity of rice, improve the stress resistance of seedlings, and prevent the phenomenon of rigid seedlings caused by low temperature in early rice fields. Generally, the application of zinc and phosphorus (1:10) mixed fertilizer 18kg per mu can increase the yield, enhance the stress resistance and improve the rice quality 7-8 days after the rice is green. 15ml~30ml/ mu of Hefeng zinc or Fenglihui zinc was sprayed after slow transplanting of rice seedlings. 4. After tillering: foliar spraying Hefeng zinc or Fenglihui zinc 15~30ml/ mu, twice, 4-6 days apart.
