Abstract

The invention relates to a chemical reagent applied to soil and particularly relates to an improving and conditioning agent for soil of saline-alkali farmlands. The improving and conditioning agent comprises the following raw materials in parts by weight: 30-40 parts of desulfuration waste, 1-2 parts of aluminum sulfate, 0.001-0.01 part of zinc sulfate, 0.001-0.01 part of manganese sulfate, 0.1-0.5 part of urea, 0.1-0.3 part of a microbial fertilizer, 10-20 parts of grass carbon and 4-6 parts of straws. The improving and conditioning agent for the soil of the saline-alkali farmlands is low in cost and convenient to apply and has no toxic or side effect.

Description

technical field [0001] The invention relates to a chemical reagent used on soil, in particular to a saline-alkaline farmland soil improvement conditioner. Background technique [0002] At present, the national saline-alkali farmland soil area accounts for about 60% of the country's land area, and the saline-alkali farmland soil is also composed of different salinity or alkaline or saline-alkaline, while in the Songnen Plain it is Suda saline-alkali soil. It is famous, but the pH (ESP) is extremely high, which is not conducive to the growth of crops, making the saline-alkali soil barren and unusable all the year round, resulting in land waste or reduced production. The existing saline-alkali farmland soil improvement conditioner mainly uses Ming vanadium as the main raw material, but the cost of Ming vanadium is high, and the soil improvement effect is not obvious. Contents of the invention [0003] The purpose of the present invention is to provide a saline-alkali farmlan...
