Pest-resistant foliage fertilizer additive for vegetables and preparation method of additive

Abstract

The invention discloses a pest-resistant foliage fertilizer additive for vegetables and a preparation method of the additive. The additive is prepared from raw materials in parts by weight as follows: sodium stearate, naphthylacetic acid, soybean residues, diethyl aminoethyl hexanoate, eucalyptus fruits, a tillering accelerator, jasmonic acid, honeysuckle flowers, wild chrysanthemum flowers, tree peony root-bark, orange peels, tobacco leaves, aluminum sulfate, a 65%-75% ethanol solution, a plant additive and a proper amount of water; the tree peony root-bark, the orange peels and the tobacco leaves contain pest-resistant active substances of plants, extraction and concentration are performed with a decoction method, a foliage fertilizer additive component is formed finally, the contact function of foliage fertilizer and vegetable foliage is increased, the duration of the foliage fertilizer on the foliage is prolonged, the foliage is protected against pests for a long time, the foliage fertilizer can be better absorbed by the vegetables, the yield of the vegetables is increased, and ageing resistance is realized.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a vegetable pest-resistant foliar fertilizer additive 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 a...

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
