Abstract

The invention discloses a nutritional type saline-alkali soil modifier which can be used for the improvement and fertilization of the new oasis and the secondary salinization soil, and belongs to the technical field of soil improvement. The modifier comprises the following raw materials in percentage by weight: 50%-70% of furfural residue, 20%-40% of matured sheep manure, 1%-2% of urea, 4%-6% of diammomium phosphate, 2%-4% of potassium chloride, 0.3%-0.5% of zinc sulfate and 0.3%-0.5% of manganese sulfate. The preparation method of the modifier comprises the following conventional steps: mixing the raw materials, grinding and sieving to prepare the nutritional type saline-alkali soil modifier provided by the invention. The modifier integrates the functions of improving saline-alkali soil,fertilizing soil and preserving moisture and fertility; and the production cost is low, the improvement effect is good, and the yield of the crop can be increased obviously.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a nutritional saline-alkali soil improver which can be used for improvement and fertilization of new oases and secondary salinized soil. Background technique [0002] Most of the newly built oases are saline-alkali wastelands. The main problems are barren soil, extremely low nitrogen and phosphorus nutrient content, lack of trace elements, high soluble salt content, poor water and fertilizer retention performance, and difficulties in crop emergence and seedling protection. The measure is to improve salinity. In addition, secondary salinization of soil is also a common problem in irrigation areas and protected cultivation. Unreasonable fertilization and irrigation have led to an increase in the salinized area year by year, which has seriously affected crop yields. Therefore, the improvement and utilization of saline-alkali land and the prevention and control of secondary...
