Abstract

The invention discloses a soil remediation agent and a preparation method thereof. The soil remediation agent comprises the following components in parts by mass: 10-30 parts of diatomite, 10-20 partsof chitosan, 30-50 parts of ardealite, 5-15 parts of a trace element supplement and 20-40 parts of microbial microcapsules. The preparation method of the soil remediation agent comprises the following steps: preparation of the trace element supplement, preparation of a mixture, preparation of a capsule core, preparation of a microbial microcapsule and preparation of the soil remediation agent. The method has the beneficial effects that (1) the problems of soil acidification, trace element deficiency, heavy metal pollution, organic matter deficiency and the like can be solved, and the soil isremediated in multiple directions; (2) the agent has water retention and fertilizer retention effects; (3) coating microorganisms by using a microcapsule technology is adopted so as to prevent the microorganisms from being influenced by environmental factors; and (4) the synergistic effect, mutual complementation, safety, long lasting time and no subsequent pollution are achieved.

Description

technical field [0001] The invention relates to the field of agricultural technology, and more specifically relates to a soil remediation agent and a preparation method thereof. Background technique [0002] Due to long-term unreasonable planting and destruction of ground plants, forestry soil has decreased fertility, poor permeability, and is not suitable for planting. The main manifestations are acidification of forest land soil, lack of trace elements, imbalance of flora, salinization, Many problems such as compaction, heavy metal pollution, lack of organic matter, and continuous cropping obstacles seriously affect crop yield and quality, and some crops even fail to harvest; therefore, changing the current soil condition through soil remediation has become an effective solution to improve soil quality and increase crop yield. [0003] However, there are still some problems with soil remediation agents at present, for example: single-purpose soil remediation agents are mos...
