Abstract

The invention discloses bioactive enzyme improved phosphogypsum nutrient soil, which is prepared from the following components in parts by weight: 40 to 60 parts of phosphogypsum; 15 to 30 parts of fungus bags; 15 to 35 parts of mountain grass powder; 5 to 10 parts of slaked lime; 15 to 20 parts of oil cake; 5 to 10 parts of potassium dihydrogen phosphate; 8 to 16 parts of sweet wormwood herb; 3-8parts of root of Soulie Barberry; 2 to 5 parts of glucoamylase and 5-9 parts of glass powder; the raw materials are dried, ground into powder, mixed and fermented to obtain the nutrient soil, and thenutrient soil is used according to the amount of 2-3 tons per mu in the manner of covering, and then is turned over for use. According to the invention, biological flora is provided through the fungus bag, inorganic compounds and metal salt in soil are rapidly decomposed, soil properties are effectively improved, the glucoamylase provides bioactive enzymes, biological flora balance is facilitated, meanwhile, the catalytic effect is achieved, decomposition of organic matters is promoted to provide nutrients, the self-repairing capacity of the soil is recovered, a long-term stable state is formed, and cost and engineering investment are reduced.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to bioactive enzyme-improved phosphogypsum nutrient soil and its preparation and use methods. Background technique [0002] Cultivated land is the basic resource and condition that human beings rely on for survival. In the 21st century, the population continues to increase, the scale of cities expands too fast and too large, the industry develops rapidly, and the arable land is gradually decreasing. To maintain sustainable agricultural development, we must first ensure the amount of arable land and quality. [0003] However, 69.27% ​​of China's cultivated land is distributed in mountains, hills and plateaus, and only 30.73% is distributed in plains and basins. Due to drought and water shortage, a large amount of cultivated land and grassland have been barren due to mining, which is difficult to use and uneven distribution of water resources. Equilibrium and oth...
