Method for preparing soil-free organic seedling culture medium for green peppers

Abstract

The invention relates to the technical field of seedling culture media for crops and especially relates to a method for preparing a soil-free organic seedling culture medium for green peppers. The method is specifically characterized in that crop straws, cow dung, rice hull charcoal, vermiculite and biogas residues are taken as main ingredients, and the soil-free organic seedling culture medium for green peppers with good permeability and high fertility is made through the steps such as material preparation, straw heap building, decomposition and medium preparation, wherein in terms of using amount, the volume ratio of the crop straws to the cow dung is (0.5-1.5):1; and weight proportions of the ingredients used in the medium preparation step are 20%-30% for the semi-decomposed straws, 10%-30% for the rice hull charcoal, 5%-15% for the vermiculite, 5%-15% for the dry biogas residues, and 30%-40% for a biogas slurry. The method for preparing the soil-free organic seedling culture medium for the green peppers provided by the invention realizes production of the soil-free organic seedling culture medium, reduces damage to farmland soil resources, realizes utilization of non-renewable resources, is environment-friendly, reduces occurrence of pest and disease damage, increases the content of soil organic matters and can increase a yield.

Description

technical field [0001] The invention relates to a method for preparing a green pepper soilless organic seedling-raising substrate, and belongs to the technical field of crop seedling-raising substrates. technical background [0002] In traditional green pepper seedling cultivation, fertile plow soil or peat is often used as seedling bed soil. The selection of plow soil will cause damage to farmland soil resources, and peat is also a non-renewable resource formed over thousands of years. At present, some domestic studies on using substrates instead of nutrient soil to raise green pepper seedlings have been carried out. The seedling substrates are basically vermiculite and perlite, mixed with nitrogen, phosphorus and potassium elements, trace elements, and bactericides and insecticides. There are also some studies on the common raw materials for seedling cultivation using renewable resources such as straw, human and animal manure, etc., through multiple biochemical treatments,...

At present, some domestic studies on using substrates instead of nutrient soil to raise green pepper seedlings have been carried out. The seedling substrates are basically vermiculite and perlite, mixed with nitrogen, phosphorus and potassium elements, trace elements, and bactericides and insecticides. There are also some studies on the common raw materials for seedling cultivation using renewable resources such as straw, human and animal manure, etc., through multiple biochemical treatments, and then adding binders, water-retaining agents, and slow-release fertilizers to produce rice seedling substrates, but this method is supplemented with auxiliary preparations. Many, cumbersome, high production costs
