Abstract

The present invention relates to a soil conditioning agent using oyster shell as main material, and it is characterized by that it is formed from oyster shell powder, polyaspartate, chitosan or its derivative and biological total or partial powder or fermentation material, their weight percentages respectively are 50-70, 2-5, 1-3 and 25-45. The described biological total or partial powder or fermentation material include upland plant total or their root, stem, leaf, flower, fruit and shell powder or fermentation material and total or partial powder of marine biotas of fish, shrimp, shellfish and algae or fermentation material. Said invention can regulate soil microbial population structure, can increase number of beneficial bacteria, raise fertilizer utilization rate, raise yield of crops and improve quality of crops.

Description

technical field [0001] The invention relates to a soil conditioner, in particular to a soil conditioner mainly composed of oyster shells. Background technique [0002] In recent years, my country's greenhouse or greenhouse planting industry has developed rapidly. Vegetable and flower land, especially greenhouse land, due to long-term high-intensity cultivation and the use of a large amount of quick-acting chemical fertilizers, the soil structure of the farmland has deteriorated, the soil trace elements are out of balance, and the soil fertility has declined, resulting in a decline in crop yield and quality. As far as the inventors know, oyster shells are made up of organic matter such as minerals and proteoglycans. The minerals are mainly calcium, and there are also various trace elements such as sodium, barium, copper, iron, magnesium, manganese, nickel and strontium. The oyster shell is composed of cuticle, prismatic layer and nacre, the main part is prismatic layer, whic...
