Problems solved by technology

In my country, foliar fertilizer spraying still uses the traditional human-powered boom sprayer as the main means. Not only does the amount of liquid medicine used is large, but also the pollution of the liquid medicine and the leakage of spraying are serious. The effective utilization rate of foliar fertilizer is only about 30%, which is far lower than that of In developed countries, soil, crops, and water are seriously polluted

Embodiment

[0027] 1 Materials and methods

[0028] 1.1 Overview of the test area

[0029] The winter wheat drone foliar spray zinc fertilizer test was carried out from October 2019 to June 2020 at the Liuyuan Base of the Maifengshou Wheat Planting Professional Cooperative in Matou Town, Dongming County, Heze City, Shandong Province (35°02′N, 115°07′ E, carried out at an altitude of 60m). The test site is located in the mid-latitude zone, the soil type is loam, and it belongs to the warm temperate monsoon climate. Its main climate features are: obvious monsoon, four distinct seasons, cold winter and hot summer, and rain and heat at the same time. The previous crop in this experiment was summer corn, and the growth and harvest were good. The basic physical and chemical properties of the plow layer soil (0-20cm) before wheat sowing are shown in Table 1.

Abstract

The invention relates to an efficient application method of winter wheat trace element fertilizer in a wheat and maize rotation system. The method comprises the following steps of applying zinc fertilizer to soil and applying zinc fertilizer and selenium fertilizer to leaf surfaces by an unmanned aerial vehicle, wherein the zinc fertilizer sprayed by the unmanned aerial vehicle is sprayed to the leaf surfaces by adopting the unmanned aerial vehicle in the wheat filling stage, and the selenium fertilizer sprayed by the unmanned aerial vehicle is sprayed to the leaf surfaces by adopting the unmanned aerial vehicle in the wheat heading and filling stages. The process of applying the zinc fertilizer to the soil and spraying the zinc fertilizer by the unmanned aerial vehicle is a relatively economical mode for increasing the yield of wheat grains on the potential zinc-deficient soil and increasing the content of trace elements such as grain zinc, and a relatively good effect is achieved forimproving the zinc nutrition quality of wheat.

Description

technical field [0001] The disclosure relates to a method for efficiently applying trace element fertilizers of winter wheat and nutritional enhancement of trace elements in grains. Background technique [0002] The information disclosed in this background section is only intended to increase some understanding of the general background of the disclosure, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes prior art that is already known to those skilled in the art. [0003] Zinc deficiency in humans is an important worldwide problem, especially in areas where grains are the staple food. As the main grain crop in my country, wheat accounts for 30% of the per capita daily energy intake, and its nutritional quality directly affects human health. The nutritional target value of zinc in wheat grains that meets the needs of human health is 45 mg / kg, while the average zinc content in Chinese wheat grains is only 23.3 ...
