Crop leaf surface micronutrient fertilizer

Abstract

A crop leaf surface microelement fertilizer is mainly composed of the following parts by weight of components: 3-10 parts of rare earth, 20-40 parts of manganese sulfate, 10-20 parts of zinc sulfate, 2-20 parts of ammonium molybdate, 1-5 parts of titanium dioxide, 20-30 parts of potassium dihydrogen phosphate, 1-3 parts of potassium iodide, 5-15 parts of ferrous sulfate and 0.5-2 parts of copper sulfate. The rare earth can improve the sweetness, enhance the taste and promote the development of roots, the potassium dihydrogen phosphate can promote the grain fullness and improve quality, and the potassium iodide can increase the yield. The titanium dioxide has good dispersion, can be used for fertilizer spraying to make the fertilizer spraying more uniform, and the bonding property of the titanium dioxide is good, so that the fertilizer sprayed onto the leaf surface is not easy to fall off. The titanium dioxide also is a catalyst carrier, has oxidation expediting effect, can promote the oxidation decomposition of effective components in the fertilizer to facilitate the plant absorption. After five years of large field experiments, by spraying according to the general production management level, the yield can be increased by more than 30%, the quality of grains, cotton, fruits and the like is improved obviously, sweetness is increased, the taste and flavor are good, the yield is increased nearly doubled around.

Description

technical field [0001] The invention relates to a crop fertilizer, in particular to a foliar micro-fertilizer for improving crop yield and grain or fruit quality. Background technique [0002] In the crop planting industry, chemical fertilizers and manure are generally used to promote crop production, which can increase crop yields and improve crop varieties to a certain extent. However, the extensive use of chemical fertilizers and farmyard manure will cause damage to the soil, thereby destroying the ecological environment. In addition, this traditional fertilization method will be affected by weather conditions. In recent years, a variety of foliar fertilizers have been developed and applied. As topdressing fertilizers, the time and amount of fertilization can be adjusted according to weather conditions and actual conditions to meet the needs of crops, and it is easy to use. At present, foliar fertilizer has been popularized and applied in a large area, and h...
