Abstract

The invention discloses a liquid fertilizer for resisting drought and preserving moisture and fertility, belongs to the technical field of fertilizer. Each 1L of the liquid fertilizer comprises the following raw materials: 60-90 g of fulvic acid, 50-80 g of a nitrogenous fertilizer (counted by N), 100-120 g of a phosphatic fertilizer (counted by P2O5), 50-80 g of a potash fertilizer (counted by K2O), 5-8 g of microelement and the balance of water; the corresponding preparation method comprises the following steps: adding the nitrogenous fertilizer, the potash fertilizer, the phosphatic fertilizer and the fulvic acid into water, stirring for dissolving, adding the microelement, stirring for dissolving, diluting with water to 1 L, uniformly stirring, and filling to obtain the liquid fertilizer. According to the liquid fertilizer provided by the invention, fulvic acid, the nitrogenous fertilizer, the phosphatic fertilizer, the potash fertilizer and the microelement in the chelating state are mixed for dissolving to form the chelated liquid fertilizer that is nutritionally balanced, better in fluidity, and stable and uniform; besides, after application of the liquid fertilizer in soil, both the water-holding capacity and the degree of porosity are improved, the growth of roots of crops in soil is promoted, and the yield-increasing effect of crops is good.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a drought-resistant, water- and fertilizer-retaining liquid fertilizer and a preparation method thereof. Background technique [0002] Fertilizer is a compound that promotes plant growth, is an essential material support for increasing crop production, and is also one of the important conditions for the development of agricultural production. China is one of the countries that consume a lot of agricultural fertilizers in the world. At present, the dosage form of fertilizers is mainly granules, and a large part of them is lost to the environment after fertilization. polluted the natural environment. In addition, China is one of the countries in the world that suffers from severe water shortage. How to save water, reduce the amount of chemical fertilizers, and protect the environment are problems that need to be solved urgently in agricultural production. [0003]...
