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 65g of desulfurized gypsum and 50g of rice 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 400° 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 10g of organic fertilizer. The mixture of organic bacterial manure is stirred evenly to obtain an improved conditioning agent, and its ingredients are: 60 g of desulfurized gypsum, 20 g of biomass coke, 10 g of biomass aq...

Embodiment 2

[0068] Utilize the method of the present invention, prepare a kind of improved conditioning agent, concrete steps are as follows:

Abstract

The invention discloses a moderate saline-alkali soil improvement conditioner as well as a preparation method and application thereof. The soil improvement conditioner comprises the following components in parts by weight: 55-60 parts of calcium salt, 18-23 parts of biomass coke, 10-15 parts of a biomass aqueous solution and 10-12 parts of an organic fertilizer. The soil improvement conditioner disclosed by the invention can quickly and effectively solves the problems of high soil alkalization degree, low fertility, larger soil pH value, clumpy soil and the like and is low in cost 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 moderately 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 h...
