Suspended liquid fertilizer for promoting plant root system growth and preparation process thereof

Abstract

The invention discloses a suspended liquid fertilizer for promoting plant root system growth and a preparation process thereof. The suspended liquid fertilizer is composed of fulvic acid, macroelement raw materials, medium-element raw materials, microelement raw materials, functional matter, a suspension auxiliary, a compound chelator, an antifoaming agent and a solution stabilizer. The preparation process comprises the following preparation steps that 1, water, potassium humate, nitrogenous fertilizer and potash fertilizer are stirred at a high speed to be prepared into a saturated mother solution; 2, water, phosphate fertilizer, the microelement raw materials, a dispersing agent, filler and a part of the antifoaming agent are stirred continuously and ground through an ultramicro grinder to form a solid-liquid mixture; 3, the saturated mother solution and the solid-liquid mixture are sufficiently mixed to be uniform in proportion in a high-speed disperser, a thickening agent, the remaining antifoaming agent and an antifreezing agent are added, and the suspended liquid fertilizer is prepared after emulsification is conducted through a high-speed emulsification pump. The suspended liquid fertilizer has the advantages that drought resistance, cold resistance and other stress resistance of crops are improved, development of crop root systems and formation of blossom buds can be promoted, and the yield and income are increased; the suspended liquid fertilizer is instantly soluble, uniform and suitable for automatic application; a suspended liquid system is good in uniformity.

Description

technical field [0001] The invention relates to the technical field of plant fertilizer production, in particular to a preparation process of suspended liquid fertilizer. Background technique [0002] Suspension liquid fertilizer technology is to suspend nutrient elements as solutes in water to form a suspension. The fertilizer effect is guaranteed by rich organic nutrients + high content of macroelements. However, the research and development and production of liquid fertilizers in my country are still in their infancy. Liquid fertilizers have problems such as low nutrient content and layered agglomeration. Although it is normal for high-concentration liquid water-soluble fertilizer products to have sedimentation and layering, it must be controlled within a certain ratio so as not to affect the use of the product. Otherwise, irrigation When fertilizing, the fertilizer is unevenly distributed or it is difficult to penetrate into the epidermal cells of the root system, which af...
