specific Embodiment approach 1

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

specific Embodiment approach 2

[0009] Specific embodiment two: the difference between this embodiment and specific embodiment one is that: the Chinese herbal medicine plant orange stem is the gentian plant orange stem. Other steps and parameters are the same as in the first embodiment.

specific Embodiment approach 3

[0010] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the medicament is mixed and pulverized by 1 part of Gentiana, 1 part of Cinnabar, 10 parts of Baicao Cream and 1 part of Alum in percentage by weight. Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.

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...
