Vegetable-growing substrate and preparation method thereof

Abstract

The invention discloses a vegetable-growing substrate, which consists of the following materials in parts by weight: 20 to 30 parts of animal dung 15 to 25 parts of diatomite, 10 to 20 parts of bran, 8 to 17 parts of vermiculite, 14 to 22 parts of leaf mold, 7 to 14 parts of plant ash, 2 to 3 parts of tobacco leaves, 5 to 10 parts of bark, 2 to 4 parts of bamboo vinegar, 5 to 8 parts of brown sugar, 5 to 13 parts of modified biological charcoal, 3 to 5 parts of Chinese herbal medicine mixture, 1 to 2 parts of maturing agent and 0.2 to 0.4 parts of high-temperature cellulose-decomposing bacterium agent. The vegetable-growing substrate has good air permeability, good pest control effect and the function of moisture and fertilizer retention, and can meet the nutritional requirement of vegetables during growth.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a vegetable planting substrate and a preparation method thereof. Background technique [0002] Substrate cultivation generally chooses materials that are loose, breathable, and have strong water retention capacity as the cultivation substrate. Commonly used cultivation substrates include peat, coconut peat, bark, etc. The traditional substrate is pure bark that is directly crushed and decomposed before use. The pure bark substrate has the problems of perishability, poor air permeability, poor fertility, and poor insect resistance. After using the bark base to mix other ingredients, the above problems can be avoided, but the early use should not be watered with a large amount of water to avoid washing away the functional ingredients. Contents of the invention [0003] The invention provides a vegetable planting substrate and a preparation method thereof, whic...

AI Technical Summary

Problems solved by technology

The traditional substrate is pure bark, which is directly crushed and decomposed before use. The pure bark substrate has the problems of perishability, poor air permeability, poor fertility, and poor insect resistance.

After using the bark matrix to mix other ingredients, the above problems can be avoided, but the early use should not be watered with a lot of water to avoid washing away the functional ingredients
