Zusammenfassung: | The invention discloses a soil property modifying agent for greenhouse planting and a preparation method thereof. The soil property modifying agent comprises the following substances in parts by weight: 50%-69% of animal excrement, 3%-4.5% of biological calcium powder, 10%-15% of potassium nitrate, 3%-5% of unpolished rice particles, 0.5%-1.25% of amino acid, 5%-7% of straw fine particles, 5%-7% of soybean fine particles, 0.5%-5% of biological decayed materials, 2%-5% of diatomite and 0.5-2% of cerium oxide. With the adoption of the modifying agent, the moisture keeping property of soil can be improved and the nutrient reserves of the soil can be increased, so that a hardening problem of the soil is completely improved and the growth of plants is facilitated; the yield of the plants is increased and the use amount of chemical fertilizers is reduced; the environmental protection degree of the plants is improved; almost components in the modifying agent are selected from natural wastes so that the modifying agent is environmentally friendly when being used; and meanwhile, the emission amount of the natural wastes can be reduced. |
