Foliar fertilizer for maize

Abstract

The invention discloses foliar fertilizer for maize. The foliar fertilizer mainly comprises, by mass, 10-14 parts of urea, 2-5 parts of monopotassium phosphate, 5-8 parts of chelated calcium, 1-3 parts of borax, 4-7 parts of fulvic acid copper, 5-8 parts of growth promoters and deionized water. According to the foliar fertilizer for the maize, ingredient supplement of the foliar fertilizer is reasonable, the nutrient elements are rich, the preparation cost is moderate, sufficient nutrients can be provided for the maize at the outcome stage, growth of the maize is facilitated, and the plump granularity and the yield of maize fruit can be guaranteed.

Description

technical field [0001] The invention relates to a foliar fertilizer for corn, in particular to a foliar fertilizer for corn with the effects of increasing yield and promoting growth, and belongs to the technical field of fertilizers. Background technique [0002] Foliar fertilizer is a fertilizer that directly applies the nutrients required by the crop to the leaf surface for the purpose of leaf absorption. When it is inconvenient to fertilize the roots of crops, such as in the later stage of crop growth, the root vitality declines and the fertilizer absorption capacity decreases; or when the soil environment is unfavorable to crop growth, such as excessive water, drought, soil too acidic, too alkaline, causing crops Root system absorption is blocked, and crops need to resume growth quickly. At this time, in order to meet the growth needs of crops, only foliar spraying measures can be taken to supplement nutrients for crops in time and maintain growth and development of crop...
