Embodiment 1

[0013] The improvement method of alkaline soil comprises the following implementation steps:

[0014] a. Loosen the soil and grind the soil finely;

[0015] b. Add cooked sheep manure and fungus dregs to the soil, and mix them evenly with the soil. The ratio of the parts by volume of the soil, cooked sheep manure and fungus dregs is 5:3:1.

Embodiment 2

[0017] The improvement method of alkaline soil comprises the following implementation steps:

[0018] c. Loosen the soil and grind the soil finely;

[0019] d. Add cooked sheep manure and fungus dregs to the soil, and mix them evenly with the soil. The ratio of the parts by volume of the soil, cooked sheep manure and fungus dregs is 8:3:1.

[0020] In actual operation, if there are leaching conditions, the soil can be leached after loosening the soil to reduce the salinity in the soil, and then add cooked sheep manure and fungus residue and mix well with the soil to further improve the survival of green plants Rate.

Abstract

The invention discloses a method for improving alkaline soil. The method is characterized by comprising the following steps of: loosening soil and porphyrizing the soil; and adding composted sheep manure and fungus dreg into the soil and mixing uniformly, wherein the volume ratio of the soil to the composted sheep manure to the fungus dreg is (5-10):(3-2):1; the composted sheep manure is sheep manure which is composted and fermented; the organic matter content of the composted sheep manure is more than or equal to 30 percent; the water content of the composted sheep manure is less than or equal to 30 percent; and the fungus dreg is waste after mushroom is planted agriculturally, is abundant in phosphorus and belongs to organic phosphate fertilizer. In the implementation process, raw materials can be obtained from the local resources, so that improvement cost is reduced, waste of husbandry is utilized effectively and the problem of environmental pollution caused by the waste of husbandry is solved. By the method, the pH value of the soil is effectively reduced and the survival rate of green plants is increased. The method is very easy to operate and worthy of popularizing.

Description

technical field [0001] The invention relates to the technical field of soil improvement of saline-alkali land in northern regions such as Xinjiang of my country, in particular to a method for improving alkaline soil. Background technique [0002] In Xinjiang and other northern areas of our country, there is a large amount of alkaline soil, and only a few plants such as red willow can survive in this alkaline soil, which leads to the selection of seedling varieties that can be planted in the process of urban greening and greening along roads in these areas. Single, does not meet the original intention of greening. In order to meet the growth of seedlings, it is not uncommon to learn from the patented technology of alkaline soil improvement. Chinese patent CN1377936A discloses a method of using waste gypsum boards to produce saline-alkali soil improvers and its products and applications. The core is to use Calcium sulfate (gypsum) replaces the exchangeable sodium in the soil,...
