Problems solved by technology

Maize is one of the target crops of microelement “biofortification”. Many scholars have conducted extensive research on the effect of genetic improvement of maize varieties on increasing yield, changes in agronomic traits, nutrient use efficiency, stress resistance and maize planting techniques. Not obvious. In addition, researchers have reported the concentration of Zn and Fe in the grains of different genotypes of maize varieties, mainly focusing on the concentrations of Zn and Fe in the grains, but there are few studies on their improvement of bioavailability

Abstract

The invention discloses a regulating fertilizer for improving the medium-trace element content in corn kernels in a Huang-Huai-Hai region and the biological effectiveness of Zn and Fe and an application method and belongs to the technical field of effect improvement of chemical fertilizers. The regulating fertilizer is prepared from, by weight, 50-70 parts of fresh seaweed, 20-30 parts of cotton seed shells, 20-30 parts of peanut shells, 10-20 parts of soybean meal, 2040 parts of corn straws, 20-30 parts of animal waste and 2-4 parts of EM bacteria. A preparation method of the regulating fertilizer comprises the following steps that the fresh seaweed is minced into pulp, cell walls are broken to obtain seaweed liquid; the cotton seed shells, the peanut shells, the soybean meal and the corn straws are mixed with the animal waste and the EM bacteria, and wetting and fermentation are performed to obtain fermentation powder; the seaweed liquid and the fermentation powder are mixed and then are stirred evenly. It is found through contrast that after the regulating fertilizer is applied, the medium-trace element contents in all varieties of corn kernels can be remarkably increased, and the biological effectiveness of Zn and Fe in corns can be improved.

Description

technical field [0001] The invention belongs to the technical field of chemical fertilizer efficiency enhancement, and relates to a fertilizer for improving the content of trace elements in grains of Huanghuaihai corn varieties and the biological availability of Zn and Fe, and an application method thereof, in particular to a fertilizer capable of increasing the content of trace elements in grains of Huanghuaihai corn varieties As well as the regulating fertilizer and application method for improving Zn and Fe bioavailability in corn grains. Background technique [0002] Trace element deficiency has become a common problem. It is speculated that among the 6 billion people in the world, more than 60% of people are deficient in Fe, more than 30% are deficient in Zn and I, and about 15% are deficient in Se. The deficiencies of Ca, Mg and Cu are also relatively high in developing countries. universal. One of the main reasons for zinc and iron deficiency is insufficient intake ...
