Abstract

The invention discloses a chelated multi-element foliage fertilizer, relating to the field of agricultural fertilizers. The chelated multi-element foliage fertilizer is prepared by mixing and chelating the following components in parts by weight: 45-55 parts of urea, 20-25 parts of potassium dihydrogen phosphate, 20-25 parts of potassium chloride, 12-18 parts of calcium-magnesium phosphate fertilizer, 8-10 parts of borax, 10-14 parts of zinc sulfate, 0.5-1.5 parts of sodium molybdate, 1.5-2.5 parts of ethylene diamine tetraacetic acid (EDTA) and 65 parts of water. The chelated multi-element foliage fertilizer has the characteristics of full nutrition, high utilization rate, good absorption, quick acting, wide application range and the like, and can be widely used as a foliage fertilizer for fruits, vegetables, grain and other crops.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizer production, in particular to a chelated multi-element foliar fertilizer. Background technique [0002] The normal growth of crops and commercial crops requires various inorganic elements, otherwise cells and tissues cannot grow and develop. Applying foliar fertilizer to crops absorbs nutrients through leaves. Although it cannot replace roots but can only supplement them, leaf absorption can selectively supplement crop nutrients faster. Now it is changing from simple chemical fertilizer to high concentration compound chemical fertilizer, and from solid chemical fertilizer to liquid chemical fertilizer. Liquid chemical fertilizer is a new type of comprehensive fertilizer. Using it is an effective means to speed up crop growth and improve seed setting rate to ensure high and stable yield. At present, there are many types of fertilization on leaves, but the fertilizer effects are diff...
