Problems solved by technology

[0003] In order to improve the condition of saline-alkali land, prevent the area of ​​saline-alkali land from expanding, and to beautify the landform of saline-alkali land, it is necessary to plant trees on saline-alkali land. However, the traditional tree planting method is used to prevent tree planting on saline-alkali land, and the survival rate is very low.

Embodiment 1

[0037] An improvement agent for tree planting soil in tidal flat saline-alkali land, comprising the following raw materials: 30kg of blocking agent, 0.03kg of acid regulator, 7kg of organic fertilizer, 0.8kg of sedimentation agent and 0.01kg of microbial agent.

[0038] The preparation method of the improver for the tree-planting soil in tidal flat saline-alkali land comprises the following steps:

[0039] (1) mixing and stirring the acid regulator and the organic fertilizer evenly to obtain a mixed material;

[0040] (2) Add blocking agent and settling agent successively to the mixed material, stir and mix for reaction, and compound granulation after the reaction is completed to obtain granules;

[0041] (3) Add microbial inoculum to the granules obtained in step (2), and mix uniformly to obtain the improvement agent for tree-planting soil in tidal flat saline-alkali land. When using the improver, the weight ratio of the improved soil to the improver is 1:3.

Abstract

The invention discloses an amendment for tree planting soil in beach saline-alkali land and a preparation method of the amendment. The amendment for tree planting soil in the beach saline-alkali landcomprises the following raw materials: 30-36 parts of a blocking agent, 0.01-0.03 part of an acid regulator, 7-10 parts of organic fertilizer, 0.2-0.8 parts of a settling agent and 0.01-0.03 parts ofmicrobial agents. The amendment for tree planting soil in the beach saline-alkali land has beneficial effects as follows: the beach saline-alkali land can be amended, free sodium ions are fixed on thesurface of residual refractory cellulose by halophilic bacteria, alkali in the soil is neutralized by the effects of the halophilic bacteria and the blocking agent, so that formation of the soil aggregate structure is promoted, the pore structure of the soil is adjusted, the alkalization degree of the soil is reduced, soil fertility of the saline-alkali land can be obviously improved, the contentof organic matter in the saline-alkali land is increased, the saline-alkali land is amended, and the survival rate of greening trees is increased.

Description

technical field [0001] The invention relates to the technical field of soil improvers, in particular to an improver for tree-planting soil in tidal flat saline-alkali land and a preparation method thereof. Background technique [0002] my country's long-term problems of soil compaction, soil fertility decline, environmental pollution, ecological damage, and quality decline of agricultural and sideline products caused by excessive use of chemical fertilizers have been highly valued by relevant national departments and agricultural science and technology circles. The extensive application of chemical fertilizers has caused Eliminate the disadvantages of soil compaction, decline in fertility and continuous increase in agricultural production costs. 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...
