Problems solved by technology

If this kind of soil is not properly developed and utilized, irrigation and cultivation, etc., secondary salinization will easily occur.
[0005] At present, the control technology of saline-alkali soil is mainly to reduce salt and alkali components by leaching, soil cultivation, and application of organic fertilizers to improve soil nutrients. The existing methods of planting plants on saline-alkali soil and carrying out native soil cultivation mainly have the following defects: ( 1) The existing method of planting plants on saline-alkali land for original soil greening has no obvious effect on reducing soil salinity for improving saline-alkali land;
[0006] (2) The existing method of planting plants on saline-alkali land for original soil greening cannot increase the content of total nitrogen, humic acid and available phosphorus in the soil;

Embodiment 1

[0042] Example 1 A method of greening the original soil of secondary salinized saline-alkali land by using water- and fertilizer-preserving nutrient soil

[0043] Include the following steps:

[0044] 1. Base selection and processing

[0045] Select the secondary salinized saline-alkali land with deep soil layer as the planting site. The indicators of the saline-alkali land are: high groundwater level, soil salt content 8-9.2g / kg, total nitrogen content in the soil 0.06-0.07%, humus in the soil The acid content is 12.6-14.6%, the available phosphorus content in the soil is 0.162-0.166%, and the soil water content is 10.2-11.9%. Apply organic fertilizer to the original soil of secondary salinized saline-alkali land, and the fertilization rate is 2.0 tons / mu. After 10 days, apply nutrient soil at an amount of 660-670 kg / mu, and then perform deep plowing with a plowing depth of 25-30cm.

Abstract

The invention provides a method for carrying out original soil greening on secondary salinization saline-alkali soil through moisture and fertilizer preserving nutrient soil. The method comprises the step of base selection and treatment; according to the step of base selection and treatment, the nutrient soil is applied, wherein the nutrient soil is prepared from brick residue kiln soil, red soil, nitrogen-phosphorus-potassium mixed fertilizer, potassium feldspar, echinacea extract, shikimic acid, composted bark powder, white breadcrumbs, sunflower seed meal, muddy chaenomeles speciosa flesh, flour weevil powder, hedgehog hide powder, a water-retaining agent and microelements; the invention further provides a preparation method of the nutrient soil. According to the planting method, the cost for carrying new soil is saved, cost is reduced, the labor cost is reduced by 52%, the functions of increasing the soil total nitrogen content and the content of humic acid and available phosphorus in the soil are achieved, and the leaf superoxide dismutase (SOD) of planted castanea mollissima ranges from 10.5 U/g to 15.4 U/g.

Description

technical field [0001] The invention relates to a method for greening original soil of secondary salinized saline-alkali land by using nutrient soil, in particular to a method for greening original soil of secondary salinized saline-alkali land by using nutrient soil that retains water and fertilizer, and belongs to the original soil of saline-alkali land Green technology field. Background technique [0002] The saline-alkali land area in the world exceeds 900 million hectares, and the saline-alkali land of various types in my country reaches 100 million hectares. The improvement of saline-alkali land is a worldwide problem.
