Zinc fertilizer is becoming a new highlight of the fertilizer industry

At present, zinc deficiency is a concern for us. According to the investigation and certification by the International Zinc Association, 50% of the world's grain-growing land has the potential risk of zinc deficiency. The results of the second national soil survey also showed that zinc deficiency in soil is the second largest nutrient restriction factor in China, and the area of ​​soil zinc deficiency has reached 51%. Zinc deficiency has become a global issue that affects both plants and humans.

The main reason for zinc deficiency in humans is the low zinc content in foods. 75% of the energy comes from rice, wheat and corn, and the zinc content of these crops is only 10-30mg/kg. To meet the nutrient absorption of human zinc, the zinc content in grains should reach 40-60mg/kg. Zinc, as an essential trace element for crop growth, not only affects the yield of crops, reduces the quality and content of agricultural products, causes the crops to be affected by pests and diseases, heavy metals, etc., but also affects human health. Therefore, scientific application of zinc fertilizer is of great significance.

Applying zinc fertilizer can promote crop yield increase

It is understood that 50% of the world's agricultural soil is deficient in zinc, which is the most scarce trace element nutrient in agriculture worldwide. In northwest China, north China and northeast China, the soil in the dry farming areas is seriously deficient in zinc. Drought and water shortage reduce the availability of zinc in the soil and affect the absorption and utilization of water. According to data obtained by the reporter, the application of zinc fertilizer to corn, wheat, cucumber, pepper, sweet potato, and peanut crops this year shows that the increase rate of zinc content in the grain of these crops has been 49.03 compared with last year. %, 5.8%, 45.79%, 20.04%, 50% and 29.98%.

In the "Directive on Scientific Fertilization for Main Crops in Autumn and Winter of 2013" issued by the Ministry of Agriculture last year, zinc fertilizer was included in this program. For rice, corn, wheat, rapeseed, cotton, potato and other major crops, vegetables and fruits in areas with zinc deficiency, etc. It is recommended to apply 1-2 kg of zinc per acre. At present, the expansion of production of zinc-containing fertilizers and its application in agriculture are the top priorities. The important role of zinc in agriculture is gradually recognized by the fertilizer industry and the majority of farmers. Driven by the demonstration and promotion of zinc fertilizers, the production and consumption of zinc-containing fertilizers have grown rapidly in recent years. According to preliminary estimates, the application area of ​​zinc fertilizer in agriculture reached 95 million mu, and the annual consumption of zinc was nearly 40,000 tons. The zinc compound fertilizer and water-soluble fertilizer had a faster growth rate. Many companies have also begun to develop and produce new fertilizers containing zinc.

Expert advice boosts future development

In view of the above development of zinc fertilizer, Du Sen, the water-saving agricultural technology division of the National Agricultural Technology Center of the Ministry of Agriculture, gave several suggestions: First, it strived for policy support. Actively strive for related support policies, strive for financial and development projects and financial support, increase promotion efforts, encourage enterprises to develop and produce zinc-containing fertilizers, and enrich zinc fertilizer varieties. The second is to organize related research. Actively carry out research on the research and development of zinc-containing fertilizers and scientific application of zinc fertilizers, carry out relevant investigations, further clarify the status of agricultural zinc deficiency in China, and study zinc-containing fertilizer varieties, dosage forms, techniques, and scientific application methods. The third is to strengthen international cooperation. Strengthen international cooperation in the research and application of zinc fertilizers, introduce advanced technologies, methods and talents such as the production and application of zinc fertilizers and zinc-containing fertilizers, speed up the introduction and transformation of technologies, and promote the application of zinc fertilizers in China's agriculture. The fourth is to expand the demonstration and promotion. The scientific application of zinc fertilizer was included in the soil testing and formulating fertilization, and the investigation of zinc deficiency in soil and the field trial demonstration of zinc fertilizer application were conducted; a recommended scheme for the scientific application of zinc fertilizer was established; and the production and application of zinc fertilizer and zinc-containing fertilizer were required for the docking enterprises of agricultural enterprises. Statistics and other work. Fifth, do a good job of propaganda and training Strongly publicize the important role of scientific application of zinc fertilizers in increasing crop yields, increasing farmers' income, and improving the quality of agricultural products. Increase awareness of the importance of scientific application of zinc fertilizers by enterprises, farmers, and people from all walks of life; development of zinc fertilizer research and development, zinc fertilizer application , zinc fertilizer scientific application technology training.
