Abstract

The invention relates to the field of fertilizers, and concretely relates to a multielement composite foliar fertilizer. The multielement composite foliar fertilizer is composed of the following substances in percent by mass: 10-20% of urea, 5-7% of diammonium phosphate, 3-5% of potassium sulfate, 0.05-0.15% of ferric sulfate, 0.02-0.04% of zinc sulfate, 0.03-0.05% of sodium molybdate, 0.1-0.3% of borax, 0.03-0.05% of magnesium sulfate, 0.07-0.09% of potassium chloride, 0.07-0.09% of iodoacetic acid, and 1-3% of a plant-growth regulator.

Description

[0001] technical field [0002] The invention relates to the field of chemical fertilizers, in particular to a multi-element compound foliar fertilizer. Background technique [0003] At present, chemical fertilizers are widely used in agricultural production in our country. Increased application of chemical fertilizers has undoubtedly played an important role in the development of agricultural production, but with the increase in the amount of chemical fertilizers used, the cost of fertilizer input has increased, soil compaction, and the use of chemical fertilizers have decreased. And chemical fertilizers have changed from simple chemical fertilizers to high-concentration compound fertilizers, and from solid fertilizers to liquid fertilizers. Liquid chemical fertilizer is the most novel comprehensive fertilizer in the world, and it is an effective means to ensure high and stable yield. There are many types of existing liquid chemical fertilizers with different components, ...
