Special zinc fertilizer for rice and its preparation and method for producing zinc-rich rice

Abstract

The invention discloses a special zinc fertilizer for rice, a preparation method thereof and a method for producing zinc-rich rice with the fertilizer. The zinc fertilizer comprises the following components in parts by weight: 4-200 parts of a zinc source by zinc weight, 50-100 parts of an acid conditioning agent, 500-1000 parts of dry fine soil and 50-200 parts of biomass filler. The zinc fertilizer is applied in the rice planting process. The rice cultivated with the zinc fertilizer and by the method has the maximum zinc content of above 60mg / kg, which is more than 6 times that of common rice. The rice cultivated by the method is natural zinc-rich rice. The rate of absorption and utilization of biological zinc of a human body is high.

Description

Technical field [0001] The invention belongs to the field of crop planting, and specifically relates to a special zinc fertilizer for rice, its preparation and a method for producing zinc-rich rice. Background technique [0002] Zinc is one of the essential trace elements for the human body. It plays an extremely important role in the growth and development of the human body. It is often hailed as the "flower of life" and the "source of intelligence". Scientists have shown that zinc is involved in the metabolism of more than 80 enzymes in the human body, especially DNA and RNA polymerase. It is directly involved in the synthesis of nucleic acid and protein, cell differentiation and proliferation, and many metabolisms. There are also some enzymes in the human body that require zinc. It activates and exerts its active effect. Therefore, zinc is an essential substance in important physiological processes such as human growth and development, reproductive genetics, immune endocrine, ...

Problems solved by technology

Improving and cultivating zinc-rich rice varieties through genetic breeding is a once-and-for-all cause for improving the zinc nutritional value of rice, and it is also a long-term work with broad development prospects; but it is a long-term systematic project, and rice varieties have Certain regional adaptability, as far as the current research progress is concerned, it is still too early to be popularized and applied, and the problem of zinc nutrition deficiency cannot be solved to the greatest extent; Nutritional rice will become a reality

Significant progress has been made in cultivating zinc-rich rice through transgenic technology, but the debate on the safety of genetically modified food seems to be inconclusive, and there are still many obstacles to the promotion and application of genetically modified rice

[0008] As for the improvement of rice zinc nutritional status through rice zinc-enriched cultivation techniques, using the existing popularized common rice varieties, in the process of its growth and development, to improve the nutritional environment, improve the utilization rate of rice zinc nutrition, and increase the zinc content of rice, the subject of this topic At present, there are not many reports on the research. At present, the main research content is mostly the effect of zinc fertilization on rice yield or the research on preventing zinc deficiency in rice. At the same time, there are also some studies on increasing the zinc content of crops by spraying zinc fertilizer on the leaves. The zinc content of rice Intensified studies are rarely found, but it has been found from a few studies that this zinc-enriching pathway in rice is still feasible, but the increase in zinc content in rice is still relatively low, generally not exceeding 25mg / kg, and generally giving The way of supplementing zinc fertilizer for rice is mainly through spreading. The utilization efficiency of zinc fertilizer in this way is also relatively low, which will also cause certain pollution to the environment and require more labor.
