Insect-damage-prevention foliar fertilizer for potatoes and preparation method of insect-damage-prevention foliar fertilizer

Abstract

The invention relates to an insect-damage-prevention foliar fertilizer for potatoes and a preparation method of the insect-damage-prevention foliar fertilizer. The insect-damage-prevention foliar fertilizer is prepared from the following raw materials in parts by weight: ammonium chloride, xinaomycin, chitosan oligosaccharide, ammonium dihydrogen phosphate, biochemical fulvic acid, urea, zinc sulfate, magnesium sulfate, citric acid, plant source additives and a proper amount of water. According to the foliar fertilizer for the potatoes, the main edible parts of the potatoes are fat roots, so that the protection of the planting soil of the potatoes is particularly important; the foliar fertilizer contains the plant source additive components, so that the continuous flow of a liquid fertilizer on the leaf surfaces is benefited, the adhesion time is relatively long, and the absorption is relatively good; and meanwhile, the additives have an insect damage prevention effect, so that the insect damage can be reduced and prevented, the environmental protection and the sanitation are achieved, and an incredible effect can be achieved without adding any pesticide type preparation.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a potato insect pest foliage fertilizer and a preparation method thereof. Background technique [0002] Fertilizers play an indispensable role in agricultural production. At the same time, a large amount of fertilizers also have a serious impact on the environment. The low utilization rate of fertilizers, the imbalance of fertilizer nutrient ratio and the difference in release frequency lead to waste and pollution of fertilizers. Not only does it have a direct impact on the soil of the planting site, but it also has a terrible impact on the water body when it is lost to the lake due to the flow of water. This also makes foliar fertilizer more and more people's attention. Liquid fertilizer can directly act on the leaves of crops. , stems and other parts are absorbed through the pores on the surface of the leaves and used directly, avoiding long-term and long-distan...

AI Technical Summary

Problems solved by technology

[0003] The use of foliar fertilizers can prevent the fixation of nutrients in the soil, and there is no loss or reduction of effectiveness and utilization due to soil denitrification, leaching, etc., but the way leaves absorb foliar fertilizers is similar to the root system, mainly through leaves The stomata on the surface absorb and enter the mesophyll cells, and then penetrate into the cuticle and cellulose wall of the leaf surface through free diffusion. The absorption speed is slightly slower than the drying speed of the liquid surface fertilizer on the leaf surface. Generally, the nutrient absorption of fruit trees When the speed reaches 50%, it usually takes 1~12 hours, and sometimes it takes several days for vegetable crops. However, the outermost layer of the epidermis of the leaves is waxy, which has a hydrophobic effect, which is not conducive to the attachment of foliar fertilizers. The effect of surface tension makes it difficult to pass through the fine stomata of leaves, so how to improve the adsorption effect of foliar fertilizer on the leaf surface and reduce the surface tension of foliar fertilizer is a key issue
