A kind of mineral soil conditioner and its preparation and application

Abstract

The invention relates to a soil improvement agent, and particularly relates to a mineral soil improvement agent and preparation and application thereof. The mineral soil improvement agent suitable for sandy land comprises the following components in percentage by weight: 30%-50% of limestone, 10%-20% of humic acid, 10%-20% of kaolin, 10%-20% of zeolite, 1%-3% of mastix, 1%-3% of chingma abutilon seeds, 1%-5% of fiveleaf akebia, 5%-10% of radix curcumae and 1%-5% of fructus toosendan, or the mineral soil improvement agent suitable for saline-alkali land comprises the following components in percentage by weight: 40%-50% of limestone, 10%-20% of diatomite, 10%-30% of humic acid, 1%-3% of mastix, 1%-5% of chingma abutilon seeds, 1%-5% of fiveleaf akebia, 1%-5% of semen plantaginis and 1%-5% of herba lycopi. The soil improvement agent disclosed by the invention is mainly used for improving the sandy land and the saline-alkali land, thereby solving the problem of land desertification. The soil improvement agent disclosed by the invention is capable of changing the soil structure by organically synthesizing mineral substances and Chinese herbal medicines and reacting through mutual activation under certain condition according to soil property by taking ecological equilibrium as a rule.
