Example Embodiment

[0020] A method for preparing green pepper soilless organic seedling-raising substrate, comprising the following steps:

[0021] (1) Material preparation: mix cow dung and straw-decomposing bacteria, and place it for a week to make straw-decomposing bacteria spread in the cow dung; chop straw, wheat straw, corn straw and other crop straws into 3-5 cm long segments, And soak it with water for later use, wherein the amount of crop straw and cow dung is straw: cow dung=(0.5~1.5):1 by volume, preferably straw: cow dung=1:1; rice husk charcoal, vermiculite, biogas slurry Ready; dregs dried.

[0022] (2) Straw construction: Lay a layer of crushed straw soaked in water, and then sprinkle a layer of cow dung mixed with straw decomposing bacteria. 45% to 65%, when the straw is held tightly by hand and water is squeezed out between the fingers, stop spraying water; the straw and cow dung mixed with straw decomposing bacteria are superimposed at intervals, and the final construction wid...

Example Embodiment

[0025] Example 1:

[0026] (1) Material preparation: put 20m 3 Cow dung mixed with an appropriate amount of straw-decomposing bacteria, placed for a week; 10m 3 Crop straws are chopped and soaked with water; rice husk charcoal, vermiculite and biogas slurry are prepared; biogas residues are dried in the sun.

[0027] (2) Heaping of straw: put 20m 3 Cow dung and appropriate amount of straw decomposing bacteria, 10m 3 Crush crop stalks and add appropriate amount of water to build a straw pile with a width of 1.6 meters and a height of 1.6 meters.

[0028] (3) The straw is decomposed: first cover the piled straw with plastic film, press it tightly, and place it for 15 days; When water is squeezed out, stop spraying water; after turning over, cover with film and leave to rot for 14 days to make half-decomposed, non-tough straw.

[0029] (4) Substrate preparation: Mix 2000kg of semi-decomposed straw with 3000kg of rice husk charcoal, 500kg of vermiculite, 1500kg of dry biogas ...

Example Embodiment

[0030] Example 2:

[0031] (1) Material preparation: put 20m 3 Mix cow dung with an appropriate amount of straw-decomposing bacteria and place it for a week; put 30m 3 Crop straws are chopped and soaked with water; rice husk charcoal, vermiculite and biogas slurry are prepared; biogas residues are dried in the sun.

[0032] (2) Heaping of straw: put 20m 3 Cow dung and appropriate amount of straw decomposing bacteria, 30m 3 Crush crop stalks and add appropriate amount of water to build a straw pile with a width of 1.7 meters and a height of 1.8 meters.

[0033] (3) The straw is decomposed: first cover the piled straw with plastic film, press it tightly, and place it for 14 days; When water is squeezed out, stop spraying water; after turning over, cover with film and leave to rot for 16 days to make half-decomposed, non-tough straw.

[0034] (4) Substrate preparation: Mix 3000kg of semi-decomposed straw with 1000kg of rice husk charcoal, 1500kg of vermiculite, 500kg of dry ...

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,...
