Abstract

The invention discloses a coastal clay saline-alkali land soil structure conditioner which comprises the following components in parts by mass: 13-18 parts of fulvic acid, 13-18 parts of biochar, 20-30 parts of polyvinyl alcohol, 0.48-0.93 part of a water retaining agent, 10-15 parts of aluminium sulfate, 0.2-0.9 part of a soil loosening agent, 50-55 parts of chicken manure, 9-15 parts of straw, 8-12 parts of alkali residue, 10-15 parts of purple loosestrife powder, 7-16 parts of vicia villosa powder, 5-10 parts of bacillus basophilus, and 4-8 parts of halobacterium cutirubrum. The coastal clay saline-alkali land soil structure conditioner has the benefits that 12 months after planting of cheiranthus cheiri, the salt content of soil layer of 0-30 cm is 0.31-0.37%, the soil volume weight is 0.91-0.96 g / cm<3>, the water stable aggregate structure of 0.25 mm or above in soil is 55-59%, and the total porosity and aeration porosity of soil are improved.

Description

technical field [0001] The invention provides a soil structure conditioner for coastal clay soil saline-alkali soil and its application in planting sweet-scented osmanthus, belonging to the technical field of soil improvement. Background technique [0002] There are too many soluble salts in the saline-alkali soil, which increases the osmotic pressure of the soil solution and causes plant physiological drought; some salt ions directly poison the plant root system, causing an imbalance in the ratio of nutrients absorbed by the plant; soil colloids in alkaline soil contain a large amount of exchange. Sodium increases the alkalinity of the soil and deteriorates the physical and chemical properties of the soil. When the soil is wet, it swells and becomes muddy, and when it is dry, it shrinks and becomes hard, and its permeability and cultivability are extremely poor. [0003] All kinds of saline-alkali soils are formed under certain natural conditions. The essence of their forma...
