Plastic plant culture medium and preparation method thereof

Abstract

The invention discloses a plastic plant culture medium, which is prepared from the following raw materials in percentage by mass: 20% to 40% of compost products, 0.1% to 0.5% of microbial agents, 2% to 10% of rice husks, 20% to 30% of turfy soil, 2% to 10% of perlite, 2% to 10% of vermiculite, 5% to 20% of insect excrement, 0.2% to 2% of bacteriostatic agents and 0.2% to 2% of growth regulators. The invention further provides a preparation method of the plastic culture medium. Agricultural waste is effectively utilized, and the resource utilization rate of agricultural energy is increased; the solid waste pollution is reduced; and besides the characteristics of a common culture medium, the medium also has the characteristics of comprehensive nutrition, strong water absorption, strong water permeability, light weight, strong plasticity and the like.

Description

technical field [0001] The invention relates to the field of plant cultivation substrates, in particular to a plastic plant cultivation substrate and a preparation method thereof. Background technique [0002] Most of the existing horticultural cultivation uses solid powdery organic substrates (nutrient soil, peat soil, composite substrates, etc.), which have problems such as high production costs, non-renewable raw materials, short service life, and poor water retention and permeability; and most of the existing substrates are It is difficult to ensure long-term nutrient content, and multiple fertilization is required. The amount of chemical fertilizers is increasing, but the utilization rate of chemical fertilizers is only about 30%, and about 70% of chemical fertilizers are deposited and fixed in the soil or are lost in rivers with rainwater. Without being absorbed and utilized, this has caused soil compaction, environmental pollution, and negative trophication of rivers ...
