Disease-resistant and insect-resistant organic vegetable planting medium

Abstract

The invention discloses a disease-resistant and insect-resistant organic vegetable planting medium. The disease-resistant and insect-resistant organic vegetable planting medium comprises, by weight, 40-45% of decaying medium, 4-6% of thermal insulation material, 5-7% of vermiculite, 40-45% of bio-organic fertilizer, 1-2% of sandy soil, 0.1-0.3% of biological bactericide, 0.1-0.3% of biological insecticide and 1-2% of inorganic compound fertilizer. The disease-resistant and insect-resistant organic vegetable planting medium prepared from the materials in proportion is high in drought resistanceand water retention, the organic fertilizer controlled release property is high, the medium contains sufficient organic matter and mineral substances and has no pollution to the environment, and green and healthy vegetables which are good in quality and free of disease can be cultivated.

Description

technical field [0001] The invention relates to the technical field of biological substrates, in particular to a disease-resistant and insect-resistant organic vegetable planting substrate. Background technique [0002] Potted vegetables are a new type of living vegetables, which can be divided into narrow sense and broad sense potted vegetables. In the narrow sense, potted vegetables are planted in plant factories or solar greenhouses in plastic pots with organic substrates. Potted planting in a broad sense is exactly to lay a 10-15cm thick organic substrate on the earth, solar greenhouse or plant factory ground for vegetable planting. [0003] At present, there are the following problems in the planting substrate of potted vegetables: 1. Vegetables are generally eaten while growing at home, requiring that worms and diseases cannot be grown. The environment and vegetables cannot guarantee the quality of green and pollution-free. 2. Potted vegetables grow in the customer's...

AI Technical Summary

Problems solved by technology

[0003] At present, there are the following problems in the planting substrate of potted vegetables: 1. Vegetables are generally eaten while growing at home, requiring that worms and diseases cannot be grown. The environment and vegetables cannot guarantee the quality of green and pollution-free

2. Potted vegetables grow in the customer's family. Once the customer does not water for a long time, the vegetables may wither or die due to lack of water

3. The current organic soilless cultivation vegetable matrix uses chemical fertilizers, and the quality of vegetables cannot be guaranteed. Moreover, due to the quick release of chemical fertilizers when grown at home for a period of time, potted vegetables will suffer from lack of fertility, wither or poor growth, or even die.

4. The current organic soilless vegetable cultivation substrate has a simple ratio, and the grown vegetables will lack mineral elements, especially trace elements

[0005] At present, due to the improper selection of raw materials, the texture of the organic vegetable cultivation substrate is not suitable, the water retention and air permeability are poor, the pH is unstable, and the C / N ratio of the fermentation substrate and the C / N ratio of different organic substrates are different in the cultivation substrate. The amount and fermentation time are also different. For example, pay attention to the amount of N added when pre-treating straw fibers. If the amount of N added is too much, the treated substrate is prone to high electrical conductivity (EC), which will affect the growth of crops; The C / N ratio of similar organic substrate materials has a floating range and will change with time. There are major technical difficulties in the selection and proportioning of cultivation substrates, and once the bacterial environment deteriorates, a large number of plants will be infected and die, or It is to use a large amount of highly toxic pesticides to cure, and the quality of vegetables cannot be guaranteed.
