Plant essential oil coated pest-repellent planting substrate and preparation method thereof

Abstract

The invention discloses a plant essential oil coated pest-repellent planting substrate and a preparation method thereof. The plant essential oil coated pest-repellent planting substrate is prepared from the following raw materials in parts by weight: 45-65 parts of satinwood leaves, 20-30 parts of other plant tissue fresh materials, 30-50 parts of an 80-90% petroleum ether water solution, 10-20 parts of beta-cyclodextrin, 60-100 parts of rape stalk, 45-70 parts of peat soil, 20-35 parts of banana peel, 1-2 parts of an EM bactericide, 5-10 parts of plant ash, 40-50 parts of dry cow dung, 5-10 parts of rice hull powder, 20-45 parts of attapulgite powder, 20-30 parts of vermiculite granules, 15-25 parts of ceramsite, 15-30 parts of spent pulping liquor and an appropriate amount of water. The straw is adopted as a planting substrate structural frame, and an organic fermentation material is added to form a loose crop culture body. The plant essential oil coated pest-repellent planting substrate has a very good breathing effect and a very good plant-source pest repellent function, and an essential oil crude extract fixed through coating has better durability.

Description

technical field [0001] The invention belongs to the technical field of planting, and in particular relates to a planting substrate coated with plant essential oil to avoid pests and a preparation method thereof.
