Problems solved by technology

However, the nutrient solution soilless cultivation method has high technical requirements for managers, and it is difficult to promote it to the public, and the cost of nutrient solution is also high, and the discarded nutrient solution will also cause environmental pollution.
However, in the existing solid substrate cultivation method, the utilization of organic fertilizers is less, and chemical fertilizers need to be added to the substrate to increase the content of nitrogen, phosphorus and potassium elements in the substrate, which reduces the pollution-free degree of agricultural products.

Embodiment

[0012] The ecological organic type soilless culture medium of the embodiment of the present invention includes pig manure, humus soil and perlite, and the pig manure, humus soil and perlite are mixed in a ratio of 2:6:2, wherein 2:6:2 The ratio can make the content of nitrogen, phosphorus and potassium nutrients in the matrix scientific and reasonable, and can provide rich nutrients for crops. The pig manure described in this example is sterilized by aerobic fermentation to ensure that the germs, pests and parasite eggs in the manure are killed, so that the crops are protected from insect damage as much as possible. After the processed pig manure, humus soil and perlite are completely stirred and mixed, drought-resistant water-retaining agent and biological bacterial fertilizer can also be added. The drought-resistant water-retaining agent can absorb excess water and prevent excess water from retting roots. When the water content in the matrix decreases, the drought-resistant ...

Abstract

The embodiment of the invention discloses an eco-organic soilless cultivation substrate. The substrate comprises swine waste, humus soil and perlite which are mixed at a proportion of 2:6:2; the substrate further comprises a drought-resistant and water-retaining agent and a bio-bacteria fertilizer; and the swine waste is sterilized by aerobic fermentation. The eco-organic soilless cultivation substrate containing the components can reduce fertilizer consumption for farm products and improve pollution-free degree of the farm products.

Description

technical field [0001] The invention relates to a cultivation substrate, in particular to an ecological organic soilless cultivation substrate. Background technique [0002] In the current agricultural production, due to the fast growth and high yield of crops grown by soilless cultivation technology, soil pollution is avoided, and clean, pollution-free, pollution-free, high-quality agricultural products can be produced without soil cultivation , greatly improving the working conditions of agricultural production, and has been widely promoted and applied. [0003] Existing soilless cultivation techniques are divided into nutrient solution soilless cultivation method and solid matrix soilless cultivation method. However, the nutrient solution soilless cultivation method has high technical requirements for managers, and it is difficult to popularize it to the public, and the cost of the nutrient solution is also high, and the discarded nutrient solution will also cause enviro...
