Problems solved by technology

At present, the substrates used in production are mostly inorganic substrates such as peat (peat), vermiculite, fine sand, perlite, and foamed plastics. Natural peat, which is more widely used, is not suitable for large-scale use because of limited resources. After use, rock wool is easy to cause Pollution

Embodiment 1

[0015] Example 1 The composition matrix of this example is made by mixing the following raw materials: 300 parts of cow dung, 600 parts of corn stalks (organic matter content 15wt%), zeolite powder (silicon content 70%, density 1.0g / cm 3 Mordenite) 70 parts, peat 250 parts (potassium content is 3-6wt%, phosphorus content is 1-3%), urea 80 parts; its preparation method is as follows: crush the air-dried corn stalks to obtain 3-5cm Corn stalk powder, mixed evenly with peat, urea, and air-dried cow dung, passed through a 2-3cm sieve; then adjusted the water content of the mixed material to 55wt% for stacking and fermentation, and when the fermentation temperature increased to 50°C, the mixture At the same time, spray water on the surface of the material to moisten the material, and continue to ferment for 7 days. Pay attention to the temperature rise. For every 5°C increase in temperature, the material is turned, stirred, and ventilated; until the temperature Decrease to 40°C, ad...

Abstract

The invention discloses a composition substrate. The composition substrate comprises the following raw materials in parts by weight: 100 to 500 parts of cattle dung, 500 to 1000 parts of corn straw, 50 to 100 parts of zeolite powder, 100 to 500 parts of grass carbon and 10 to 200 parts of urea. The cattle dung which is an organic fertilizer and the grass carbon which is an organic matter are fermented, and then the urea is added, so that rich nutrient elements can be provided; the zeolite powder, which contains major elements and trace elements required by the growth of sprouts, is included in the composition, and meanwhile, the zeolite powder has excellent ion exchange and adsorption effects, is good in stability, biotoxicity resistance, oxidation resistance and the like, and has the benefits of being capable of absorbing heavy metal ions. The composition substrate is used for both seedling culture and cultivation of vegetables in greenhouses, is not harmful to the soil; the organic matter is used instead of a chemical fertilizer, so that a crop is hardly influenced.

Description

technical field [0001] The invention relates to a substrate, especially a composition substrate, and belongs to the technical field of agricultural production. Background technique [0002] The vegetable greenhouse is a frame-covered structure with excellent thermal insulation properties. Its appearance allows people to eat off-season vegetables. Generally, the vegetable greenhouse uses a bamboo structure or a steel structure frame, covered with one or more layers of thermal insulation plastic film, thus forming a greenhouse space. The outer film can well prevent the loss of carbon dioxide produced by the growth of vegetables inside, so that the shed has a good heat preservation effect. In the process of greenhouse cultivation, for a long time, the excessive application of chemical fertilizers and organic fertilizers without harmless treatment has caused serious damage to the greenhouse soil, soil pH imbalance, excessive salt accumulation, aggravation of diseases and insec...
