Embodiment 1

[0062] Utilize the method of the present invention, prepare a kind of improved conditioning agent, concrete steps are as follows:

[0063] (1) Stir and mix 55g of desulfurized gypsum and 45g of corn stalks, put them into a fixed reaction vessel, the front of the fixed reaction vessel is connected to a nitrogen tank, and the rear is connected to a sleeve condenser;

[0064] (2) Continuously feed a small amount of nitrogen into the fixed reaction vessel, heat the fixed reaction vessel to 350°C and keep it for 1 hour, and the gas product is passed into the sleeve condenser to condense and recover the liquid product;

[0065] (3) After the reactor is cooled to room temperature, collect the solid product, and after simple crushing and crushing, stir and mix with 15g of organic bacterial fertilizer. The mixture of organic bacterial manure is stirred evenly to obtain an improved conditioning agent, and its ingredients are: 50 g of desulfurized gypsum, 20 g of biomass coke, 15 g of bi...

Abstract

The invention discloses a seriously-saline-alkali soil conditioner as well as a preparation method and application of the seriously-saline-alkali soil conditioner, wherein the soil conditioner comprises the following components in parts by weight: 50-55 parts of calcium salt, 20-25 parts of biomass cokes, 13-16 parts of a biomass water solution and 12-15 parts of an organic fertilizer. The soil conditioner can be used for rapidly and effectively solving various problems such as high soil alkalization degree, low fertility, high soil pH value and soil agglomeration, and is low in price and low in heavy metal content.

Description

technical field [0001] The present invention relates to the field of agriculture, in particular to a soil improvement conditioner and its preparation method and application, more specifically to a soil improvement conditioner, a method for preparing the soil improvement conditioner and a method for improving severely salinized soil. Background technique [0002] There are large areas of saline-alkali land distributed in our country, and the degree of salinization is expanding. The salinization of land not only causes a large amount of agricultural production reduction in our country, but also causes a lot of losses. Due to the increasingly serious degree of salinization, large areas of land have gradually become wasteland. Transforming saline-alkali land and improving the agricultural production of saline-alkali cultivated land is one of the important tasks of agricultural development in my country. [0003] The improvement of saline-alkali land in my country has a long his...
