Embodiment Construction

[0022] Below in conjunction with embodiment, further set forth the present invention. In the following detailed description, certain exemplary embodiments of the invention are described by way of illustration only. Needless to say, those skilled in the art would realize that the described embodiments can be modified in various different ways, all without departing from the spirit and scope of the present invention. Accordingly, the description is illustrative in nature and not intended to limit the scope of the claims.

[0023] An organic conditioning agent for transforming saline-alkali land, comprising the following components in parts by mass: 100 parts of desulfurized gypsum, 40-60 parts of plant straw, and 20-40 parts of conditioning auxiliary agent. Preferably, 100 parts of desulfurized gypsum, 50 parts of plant straw, and 30 parts of conditioning auxiliary agent. The conditioning aids include livestock and poultry manure or / and kitchen waste.

Abstract

The invention discloses an organic conditioner for transforming saline-alkali soil and an application method of the organic conditioner. The organic conditioner comprises the following components in parts by mass: 100 parts of desulfurized gypsum, 40-60 parts of plant straws and 20-40 parts of a conditioning auxiliary agent. Through the conditioner, the pH value of the soil can be reduced by about4%, the total salt content is reduced by about 78%, and the dissolution of calcium carbonate can be promoted, so that the concentration of Ca<2+> is increased. An exchange effect is carried out on the Ca<2+> and Na<+> on the soil colloid, so that the adsorption of the soil colloid to the Na<+> is reduced, and the Na<+> is replaced out and enters a soil solution. The soil solution is leached downwards under the action of hydrostatic pressure, so that the physical and chemical properties of the soil are improved, and the agglomeration property of the soil is enhanced.

Description

technical field [0001] The invention relates to the technical field of saline-alkali soil improvement, in particular to an organic conditioner capable of improving the soil condition of saline-alkali land so that it is suitable for the growth of crops and an application method thereof. Background technique [0002] There are a large number of saline-alkali lands in our country. The yield of crops planted on these lands is very low, or even extinct. If no crops are planted on the saline-alkali land and left unattended, the saline-alkali land will slowly erode to the good land, and the area of ​​the saline-alkali land will become larger and larger, so Harnessing and improving saline-alkali land is a national plan and an urgent matter. [0003] The quality of soil physical conditions is closely related to microaggregates. Soil microaggregates are the particle units that constitute the soil structure, and largely influence the quality characteristics of the soil structure. Soi...
