Additive capable of promoting effect of foliar fertilizer for pine and preparation method thereof

Abstract

The invention discloses an additive capable of promoting the effect of foliar fertilizer for a pine and a preparation method thereof. The additive is prepared from the following raw materials by weight: oligosaccharide, compound sodium nitrophenolate, phosphatidylcholine, attapulgite, Chinese medical stone, plant ash, carboxymethyl cellulose, neem extract, amino acid powder, cobaltous sulfide, aluminum sulfate, an ethanol solution with a concentration of 65 to 75%, a plant additive and a proper amount of water. According to the invention, mineral stone having undergone pyrolysis is subjected to levigation, and trace elements having undergone oxidation in the process of pyrolysis are hydrolyzed during levigation; and then a precipitating agent is added so as to allow particles to settle in the process of levigation, so the clear foliar fertilizer additive is obtained and can prevent non-ideal absorbing and breathing effect caused by blockage of leaf pores by the particles. The plant active protoplasm, phosphatidylcholine, carboxymethyl cellulose and the like included in the additive are capable of promoting adhesion and bonding of liquid drops, so the additive can promote bonding between the foliar fertilizer and pine needles of the pine and improve the absorption effect of the foliar fertilizer.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to an additive for promoting the effect of pine leaf 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...

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
