Additive of orange leaf fertilizer and preparation method thereof

Abstract

The invention discloses an additive of an orange leaf fertilizer and a preparation method thereof. The additive is prepared from, by weight, coal ash, rice straw, sodium selenite, pyroligneous liquor, blast furnace coal slag, sodium selenite, citric acid, ground phosphate rock, limestone, shells, kaolin, humic acid powder, glycine, aluminum sulfate, a 65-75% ethanol solution, plant additives and an appropriate amount of water. Natural rock flour contains a large amount of various elements and microelements, the addition of nutritive elements is particularly crucial for the leaf fertilizer, the concentration control amount is quite small due to the absorption limitation, and therefore the addition amount of microelements is more difficult to control. High-temperature pyrolysis is carried out on mineral stone, and then, a water solution rich in various complexing agents is utilized for extracting and chelating elements; on one hand, microelements can be successfully obtained; on the other hand, the chelated elements can be more easily absorbed.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to an additive for citrus 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-dist...

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
