Abstract

The invention discloses a special organic/inorganic compound fertilizer for pasture with water/fertilizer retention and soil fixation functions. In order to satisfy the demands for pasture growth in soil erosion regions in Southern China for the fertilizer, the fertilizer is prepared from organic N, inorganic N, P2O5, K2O, a high-water-absorptivity resin and a high-molecular polymer according to the weight ratio of 5:5:5:5:2:2. The special organic/inorganic compound fertilizer for pasture can effectively enhance the water/fertilizer utilization efficiency, reduce the labor intensity, save the labor employment, increase the labor benefits and reduce the soil erosion, is hopeful to enhancing the yield and quality of the pasture, and has important practical meanings for farmer income increase, agricultural synergy, rural development and agricultural ecological environment protection.

Description

technical field [0001] The invention belongs to the technical field of chemical fertilizers, and in particular relates to an organic-inorganic compound special fertilizer for forage grass with the functions of water and fertilizer conservation and soil fixation. Background technique [0002] According to the latest report of the Ministry of Water Resources of my country, the soil erosion area in China has reached 3.5692 million km 2 , the area to be treated urgently is nearly 2 million km 2 . Especially in the red soil area in southern my country, due to the large amount of rainfall and concentration, the low mountains and hills intersect, the terrain is broken, the slope is large, the parent rock has weak corrosion resistance, and the developed red soil is highly erodible. In addition, the population density is large, and the contradiction between man and land is prominent. , is one of the areas with the most severe soil erosion in my country. At present, the harms of soi...
