Abstract

The invention relates to a saline-alkali soil conditioner and a preparation method thereof. The saline-alkali soil conditioner is constituted by glacial acetic acid, citric acid, oxalic acid and tap water. The preparation method comprises the following steps: weighing the tap water, citric acid and oxalic acid according to weight ratio and placing in a reaction kettle; starting stirring, warming up to 40 DEG C to 60 DEG C for 0.5 hour to 1 hour; weighing the glacial acetic acid according to weight ratio and placing in the reaction kettle; stirring, warming up to 50 DEG C to 60 DEG C for 0.5 hour to 1 hour; cooling down to 25 DEG C to 40 DEG C; carrying out measurement packaging after the samplings pass the inspection to obtain the finished product of saline-alkali soil conditioner. The saline-alkali soil conditioner in the invention is simple in manufacturing process, low in raw materials and production cost, and can realize the improvement of soil physicochemical property, inhibit theascending of saline matter and neutralizing the alkalinity of the soil.

Description

technical field [0001] The invention relates to soil improvement, in particular to a saline-alkali soil improver, and also relates to a preparation method of the saline-alkali soil improver. Background technique [0002] my country is a large agricultural country, but not a strong one. The total area of ​​saline-alkali land in the country is 100 million hectares, of which 37 million hectares are saline soil, 45 million hectares are residual saline soil, and 45 million hectares are potential salinization soil. 18 million hectares, when the salt content of the soil surface exceeds 0.6%, most plants can no longer grow. When the soluble salt content in the soil exceeds 1.0%, only some plants specially adapted to the saline soil can grow. This leads to a large area of ​​saline-alkali soil that cannot meet the growth needs of plants, seriously affects the ecological balance, and is extremely harmful. Therefore, the improvement and utilization of saline-alkali soil, the protection...
