Rice zinc nutrition biological enhancement technology

Abstract

The invention discloses a rice zinc nutrition biological enhancement technology belonging to the technical field of plant nutrition and food science. Rice is a main source of nutrition and energy of nearly half of populations in the world. More than half of school age populations in China are insufficient in dietary zinc nutrition acceptable daily intake, and women and children widely have zinc deficiency; zinc can be simply, conveniently, widely and continuously replenished through foods, so that the zinc nutrition deficiency of a human body is solved, thus the content of zinc in the rice needs to be remarkably increased so that the common rice becomes zinc-rich rice rich in zinc nutrition, which is the problem to be solved by the invention. The technology is realized as follows: a rice zinc-rich fertilizer is prepared according to a certain component ratio, and is sprayed and applied as required after rice flowers, so that the intensified absorption of the rice to the zinc nutrition is stimulated, and the zinc is enriched into grains; after the rice is processed, the content of the zinc in polished rice can be increased by about 30 percent in comparison with that of a contrast product. By applying the technology, the content of the zinc in the rice can be increased and further the zinc-rich rice rich in zinc nutrition is produced.

Description

technical field [0001] The invention belongs to the technology in the fields of plant nutrition and grain science. Background technique [0002] Increasing the nutritional content of trace elements in staple foods is an effective way to improve the nutritional imbalance of trace elements in the human body. At present, about 40% of the world's population faces micronutrient deficiency, especially women and children in poor areas of developing countries. The lack of zinc in the human body is second only to iron. Zinc deficiency in the human body can cause anorexia and heterophagia. Zinc deficiency in children can induce dermatitis, lead to slow growth and development, short stature, poor mental development, and reduced immune function. Zinc deficiency in pregnant women can affect fetal development. In January 2005, the Office of the Women and Children Working Committee of the State Council and the China Children's Center jointly announced the results of the "Survey on the He...

Problems solved by technology

Li Zhigang, Ye Zhengqian, Yang Xiaoe, etc. from Zhejiang University (The effect of zinc supply level on rice growth and zinc accumulation and distribution, China Rice Science, 2003) studied the effects of five zinc sulfate concentrations on Jasper Zaowa, 26715, Zhejiang through hydroponic experiments. Nong 921 and other three rice varieties have the influence of grain zinc accumulation. Their research shows that the zinc content of polished rice of different varieties increases to va
