Abstract

The invention discloses an acid soil improver which is prepared from the following raw materials in parts by weight: 10 to 15 parts of urea, 5 to 8 parts of potassium sulfate, 8 to 10 parts of ammonium nitrate, 6 to 8 parts of potassium chloride, 4 to 6 parts of ammonium dihydrogen phosphate, 10 to 15 parts of silicon earth, 30 to 35 parts of straw, 5 to 8 parts of cellulase, 4 to 6 parts of fishbone meal, 2 to 4 parts of lactic acid bacteria, 10 to 12 parts of waste sorghum and 10 to 15 parts of pearlite. The acid soil improver disclosed by the invention has the advantages that the urea, thepotassium sulfate, the ammonium nitrate, the potassium chloride, the ammonium dihydrogen phosphate and the silicon earth can provide nutritional ingredients of nitrogen, phosphorus, potassium and thelike needed by soil; the straw, the cellulase, the fish bone meal, the waste sorghum and the perlite not only can provide nutritional ingredients, but also can improve soil acidity and adjust soil acid-base balance; furthermore, the straw is fully utilized, acid soil can be well adjusted, soil acid-base balance can be achieved, and planted crops can grow better.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, in particular to an acidic soil improver. Background technique [0002] Soil amendments are materials used to improve the physical, chemical and biological properties of soil to make it more suitable for plant growth, rather than mainly providing plant nutrients. [0003] Now many soils are acidic soils, and it is impossible to grow any crops. Acidic soil will reduce the number of beneficial microorganisms in the soil, thereby affecting the decomposition of organic matter and the cycle of nitrogen, phosphorus, potassium, sulfur and other elements. Moreover, it will also cause the breeding of pathogens and increase of root diseases, such as soil acidification will aggravate the breeding and spread of root nematode diseases of crops. Acidic soil will cause the fixation of nutrient elements. For example, when the pH value of the soil is lower than 6, the fixation rate of phosphorus in the...
