Special silicon-magnesium-zinc rice high-yield fertilizer

Abstract

The invention discloses a special silicon-magnesium-zinc rice high-yield fertilizer and relates to the technical field of agricultural fertilizer production. The fertilizer comprises a rice seedling raising fertilizer, a rice base fertilizer, a rice weeding-free additional fertilizer and a rice additional fertilizer. The fertilizer can ensure the nitrogen, phosphorus and potassium nutrient required in the whole process of breeding the rice, has the characteristics of convenience in use and the like and is suitable for the rice planted in provinces of regions south of Yangtze River in China.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizer production, in particular to a high-yield special fertilizer for silicon-magnesium-zinc rice. Background technique [0002] Reasonable fertilization can not only increase yield, improve crop quality, but also keep soil nutrients in balance, which is conducive to fertilizing soil fertility. However, in the prior art, rice fertilization is mostly based on conventional elemental fertilizers such as urea, ammonium bicarbonate, and diammonium phosphate. Long-term application of elemental fertilizers will have adverse effects on the soil and crops: First, it will cause an imbalance in the proportion of various nutrients in the soil. After the elemental fertilizer is applied to the soil, it will break the original nutrient balance of the soil, and long-term excessive application without supplementing organic matter. Excessive consumption of soil organic matter and imbalance of nutrient r...

Problems solved by technology

Long-term application of elemental fertilizers will have adverse effects on the soil and crops: First, it will cause an imbalance in the proportion of various nutrients in the soil. After the elemental fertilizer is applied to the soil, it will break the original nutrient balance of the soil, and long-term excessive application without supplementing organic matter. The excessive consumption of soil organic matter and the imbalance of nutrient ratio will affect the efficiency of chemical fertilizers; secondly, the ecological environment of farmland will be destroyed. Excessive application of chemical fertilizers will cause a large amount of chemical substances to enter the soil, air and water systems through leaching, volatilization and fixation. As a result, the environmental conditions gradually deteriorate, especially the increase of chemical substances in the water system, and eutrophication seriously affects personal safety; third, the physical and chemical properties of the soil will deteriorate, and the long-term application of simple chemical fertilizers will lead to the decline of soil organic matter, the reduction of aggregate structure performance, and the intensification of soil compaction. Fertilizer and water retention capacity is reduced; fourth, the soil microbial flora will be destroyed, excessive application of chemical fertilizers, especially nitrogen fertilizers, has a killing and inhibitory effect on microorganisms, long-term application, a large number of microorganisms die, soil microbial flora changes, many Beneficial microorganisms change from dominant populations to secondary populations, and crops are prone to various diseases; fifth, the quality of agricultural products will decline, and the fertilizer effect of chemical fertilizers will be faster, which has a significant effect on the early growth of crops, but is not good for crop nutrient accumulation. Absorbed by crops and accumulated in plants, affecting product quality
