Abstract

The invention provides a method for performing natural soil greening on slight alkaline land by using a salt-resistant water-retaining agent containing attapulgite. The water-retaining agent comprises attapulgite, acrylic acid, acrylamide, pine needle powder, walnut leaf powder, cassava starch, yam powder, corn stalk powder and bean peel powder. The preparation method comprises leaf powder treatment. The leaf powder treatment comprises a step of monomer solution preparation and a polymerization step. The invention further provides application of the water-retaining agent to trifolium repens plantin in saline-alkali soil. The method has the advantages that the prepared water-retaining agent has high water absorbing capability in distilled water, rainwater, and NaCl solution with a concentration of 0.6%, the capability of water absorption in the distilled water can reach 1030-1300 times the weight of itself, the capability of water absorption in the rainwater can reach 680-820 times the weight of itself, and the capability of water absorption in the NaCl solution with a concentration of 0.6% can reach 390-530 times the weight of itself.

Description

technical field [0001] The invention relates to a method for afforesting original soil of mild saline-alkali land with a salt-tolerant water-retaining agent containing attapulgite, which belongs to the technical field of landscaping. Background technique [0002] Saline-alkali soil is a general term for saline soil and alkaline soil. Saline soil mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate, the pH value is high, the soil is alkaline, the organic matter content of saline-alkali soil is small, the soil fertility is low, the physical and chemical properties are poor, it is not easy to store water, and the anion and cation harmful to crops Many, crops are not easy to promote seedlings. [0003] Attapulgite, also known as Palygorskite or palygorskite, is a hydrous magnesium-rich aluminum silicate clay mineral with a c...
