Example Embodiment

[0008] Specific embodiment 1: The method for improving saline-alkali soil in this embodiment is realized by the following steps: when plowing the land, spray the medicine on the ground at an amount of 4-8 kg / mu, and then crush the Chinese herbal medicine orange stems and press 140-160 kg Sprinkle on the ground at an amount per mu, plow again, then sprinkle oxalic acid on the ground at an amount of 4-8 kg / mu, and plant crops; that is, the improvement of saline-alkali land is realized; wherein the weight percentage of the agent is increased from 0.5 to 2 parts gentian, 0.5-2 parts cinnabar, 8-12 parts Baicao cream and 0.5-2 parts alum are mixed and pulverized.

Example Embodiment

[0009] Specific embodiment two: This embodiment is different from the specific embodiment one in that the Chinese herbal medicine plant orange stalk is a gentian plant orange stalk. The other steps and parameters are the same as in the first embodiment.

Example Embodiment

[0010] Specific embodiment three: This embodiment is different from specific embodiment one or two in that the medicament is made by mixing 1 part of gentian grass, 1 part of cinnabar, 10 parts of Baicao frost and 1 part of alum by weight percentage. The other steps and parameters are the same as in the first or second embodiment.

Abstract

The invention discloses a saline-alkali soil improvement method which belongs to saline-alkali soil improvement field and solves the technical problem that the current saline-alkali soil with a pH value more than 10 is unsuitable for plants to grow. The saline-alkali soil improvement method comprises the steps as follows: during ploughing, medicament is spread in the soil; then Chinese herbal medicine straws are cracked and spread in the soil; then ploughing is implemented again and oxalic acid is spread in the soil; and finally crops are planted; in the way, the saline-alkali soil improvement is realized. The pH value of the saline-alkali soil can be reduced to be lower than 7.5 through the saline-alkali soil improvement method, thus achieving the normal requirements on farmland irrigation water, softening the soil and strengthening the air permeability.

Description

technical field [0001] The invention belongs to the field of soil improvement, in particular to a method for improving saline-alkali land. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. In my country, there are 99.13 million hectares. The formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. [0003] The pH value of saline-alkali soil is above 10, which is not suitable for plant growth. Contents of the invention [0004] The invention solves the technical problem that the pH value of soil in saline-alkali land is above 10 and is not suitable for plant growth; and provides a method for improving saline-alkali land. [0005] The improvement method of saline-alkali land in the...
