Disease-resistant and pest-resistant culture substrate based on agricultural wastes and preparation method thereof

Abstract

The invention discloses a disease-resistant and pest-resistant culture substrate based on agricultural wastes and a preparation method thereof, and relates to the technical field of soilless culture.The disease-resistant and pest-resistant culture substrate comprises the following components in parts by weight: 800 to 1000 parts of crop straw, 5 to 200 parts of edible-fungus chaff, 200 to 400 parts of livestock and poultry manure, 0.2 to 0.5 part of a straw decomposing agent, 50 to 100 parts of ash from a biomass power plant, 50 to 100 parts of coal slag, and 0.5 to 1 part of a microbial pesticide. The disease-resistant and pest-resistant culture substrate provided by the invention has the advantages of scientific proportion, comprehensive nutrition, sufficient nutrients, moderate bulk density, good ventilation and water permeability, and capability of being used as a seedling raising substrate of a plant in a seedling stage, and a culture substrate and a soil improvement conditionerfor a crop in a whole growth period. The disease-resistant and pest-resistant culture substrate provided by the invention comprises a large number of beneficial microorganisms, so the growth of the crop is promoted, and the occurrence of diseases and pests is effectively prevented and controlled.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation, and in particular relates to a pest-resistant cultivation substrate based on agricultural waste and a preparation method thereof. Background technique [0002] As a new technology of crop cultivation, soilless cultivation has been familiar and recognized by the majority of producers for its characteristics and advantages. Compared with traditional soil cultivation, it is water-saving, fertilizer-saving, labor-saving, easy to manage, and can increase crop yield. and quality, avoid the occurrence of continuous cropping obstacles, make full use of space, and are not subject to geographical restrictions. Soilless cultivation frees agricultural production from the limitation of soil, and can automatically control the growing environment of crops, which is conducive to the realization of agricultural modernization. [0003] At present, the main form of soilless cultivation is substrate cu...

AI Technical Summary

Problems solved by technology

However, some raw materials of this type of matrix have the following disadvantages: firstly, the sources of raw materials are not extensive, unevenly distributed, and have certain geographical limitations.

Although processed coconut peat, pine bark, and dried moss are suitable for cultivating plants, the sources of raw materials are not widely distributed, and some still rely heavily on imports

Secondly, due to the residues of diseases and insect pests in the substrate raw materials, serious pests and diseases occur during the growth of crops. It is often necessary to add a large amount of insecticides and fungicides in the process of preparing substrates, which significantly affects the quality of crops.

Third, the raw material formula or production process is relatively complicated and the cost is high

Affected by farming patterns and lifestyles, these resources are completely in a state of high consumption, high pollution, and low output. A considerable part of crop straw, fungus chaff, and livestock and poultry manure are discarded or burned, and have not been rationally developed and utilized. , not only waste a lot of resources, but also cause continuous pollution pressure on the agricultural ecological environment, not only pollute the air, block the river, but also seriously pollute the surface water body and groundwater, restrict the sustainable development of agriculture, and destroy the green environment of the countryside. Therefore, the use of agricultural waste Preparation of soilless pest-resistant cultivation substrate not only saves resources, reduces pollution, protects the environment, but also recycles waste
