Abstract

The invention relates to a novel drought resistant synergistic water fertilizer conditioner and a preparation method thereof. The novel drought resistant synergistic water fertilizer conditioner comprises the following raw materials by weight percent: 0-3% of polymers, 20%-30% of natural minerals and 67%-77% of farmland organic wastes. The preparation method of the water fertilizer conditioner comprises the following steps: 1) preparing polymers respectively, and fermenting farmland organic wastes; 2) pretreating and mixing the fermented farmland organic wastes and natural minerals, and then mixing with the polymers, adding natural minerals twice to reach the required proportion; and 3) using the mixed materials to prepare water fertilizer conditioner particles, and inspecting to obtain the finished product. The invention has the following beneficial effects: by adopting the novel drought resistant synergistic water fertilizer conditioner, the water content and nutrients of the soil can be effectively adjusted, water and nutrient can be preserved, the soil can be improved, the growth microenvironment of seeds or plants can be improved and the crop yield can be increased; and the water fertilizer conditioner has the functions of resisting drought, increasing the production, increasing the efficiency and protecting the environment.

Description

technical field [0001] The invention relates to a water and fertilizer conditioner, in particular to a novel drought-resistant and synergistic water and fertilizer conditioner, a preparation method thereof, and belongs to the technical field of soil and water and fertilizer conditioners. Background technique [0002] The water and fertilizer conditioner originated in the late 1970s, and has gradually developed since then. Today, there are about dozens of species. It is a high-tech product developed on the basis of the application of water-retaining agents. The research on the application effect system of water and fertilizer conditioners in my country started from the "Eighth Five-Year Plan", and then the research has developed rapidly. From many domestic and foreign literature reports, we know that due to the different raw materials of water and fertilizer conditioners (water-retaining agent, fertilizer properties) and the preparation Different methods have different applica...
