Abstract

The invention discloses a nano saline alkali soil improvement agent. The nano saline alkali soil improvement agent comprises the following components according to a formula: 48-92wt% of ardealite, 0.001-5wt% of boric acid, 0.01-10wt% of zinc sulphate, 2-30wt% of urea phosphate, 1-35wt% of potassium fulvic acid and 0.001-5wt% of nano photocatalyst. The nano saline alkali soil improvement agent contains the nano photocatalyst, and heavy metal content in ardealite can be reduced by utilizing photochemical characteristics of the nano photocatalyst; soil source microorganisms of disease are killed by utilizing sterilization characteristic of a nano material; besides, surface activation performance of the nano material is utilized for improving ion exchange performance of the improvement agent and improving fertilizer efficiency of the improvement agent; and meanwhile, the problems that a contact area between a calcium preparation and soil particles is small as particles of a calcium preparation are larger and the capacity for replacing Na<+> in soil colloid by virtue of Ca<2+> is poorer in an existing salinity soil improvement agent are solved.

Description

technical field

[0001] The invention relates to a saline-alkali soil improver. Background technique

[0002] According to incomplete statistics from the United Nations, there are about 1 billion hectares of saline soil in the world, and about 1.2×10 5 ha irrigated land loses productivity due to salinization. Therefore, the study of saline-alkali soil amendments is an important guarantee to ensure that the red line of 1.8 billion mu of cultivated land in my country will not be affected.

[0003] At present, there have been a large number of research results and products in the research and production of soil conditioners at home and abroad. There are many single improvers such as zeolite, fly ash, sludge, green manure, and polyacrylamide, which have been studied more in salinized soil improvers, but they have problems such as incomplete improvement effects or negative impacts to varying degrees. In order to further improve the improvement effect of soil amendments and redu...
