Problems solved by technology

Among them, the first three disinfection methods are easy to cause pollution to the ecological environment due to the high toxicity of the pesticides used and the high residual concentration.
The fourth disinfection method has less pollution to the environment, but the effect is not good, and the disinfection is weak. The simple solar disinfection method can only make the temperature of the 10cm underground soil layer reach 50-60°C, and has no effect on the germs in the deeper soil layer.
The equipment required for the fifth disinfection method is expensive, the application procedure is complicated, and the cost is increased

Embodiment 1

[0017] The preparation of organic cultivation soil is to use the high temperature period of composting and fermentation of waste bio-organic matter to sterilize the soil, remove insect eggs and kill weed seeds, including the pretreatment of raw materials, mixed fermentation and aging. The pretreatment of raw materials Including the treatment of garden soil and the treatment of waste biological organic matter:

[0018] (1) Pretreatment of raw materials

[0019] a. Treatment of garden soil: use linsol as garden soil, take 5m 3 Shade-dried leaching soil with a water content of 30% (w / w), crushed to a particle size of 1mm and sieved for later use;

[0020] b. Treatment of waste bio-organic matter: waste bio-organic matter is selected from livestock and poultry manure, and 5m 3 The moisture content of livestock and poultry manure is adjusted to 40% (w / w), the carbon-to-nitrogen ratio (C / N) is 35, and the piles are piled up, turned over once a day, and water can be added appropria...

Embodiment 2

[0024] Preparation method is with embodiment 1:

[0025] (1) Pretreatment of raw materials

[0026] a. Treatment of garden soil: select alpine soil for garden soil, take 5m 3 Shade-dried alpine soil with a water content of 30% (w / w), crushed to a particle size of 0.8mm and sieved for later use;

[0027] b. Treatment of waste bio-organic matter: waste bio-organic matter is made of straw, and 5m 3The straw moisture is adjusted to 45% (w / w), the carbon-to-nitrogen ratio (C / N) is 45, piled up into piles, turned once a day, and water can be added appropriately when turning the piles, and the moisture content of the piles is 45%. (w / w), the waste bio-organic matter compost when the temperature of the center of the pile reaches 50±2°C, set aside;

[0028] (2) Mixed fermentation: Take 5m of waste bio-organic matter after treatment 3 with 0.1m 3 The sieved garden soil is mixed, the mixing ratio is 1:0.02 (v / v), and the water content of the mixture is adjusted to 50% (w / w), piled i...

Embodiment 3

[0031] Preparation method is with embodiment 1:

[0032] (1) Pretreatment of raw materials

[0033] a. Treatment of garden soil: choose iron-aluminum soil for garden soil, take 5m 3 Shade-dried iron-aluminum clay with a water content of 30% (w / w), crushed to a particle size of 0.8mm and sieved for later use;

[0034] b. Treatment of waste bio-organic matter: waste bio-organic matter is selected from fungus sticks, and 5m 3 The moisture content of the fungus sticks is adjusted to 45% (w / w), the carbon-to-nitrogen ratio (C / N) is 45, and the piles are piled up, and the piles are turned once a day. When turning the piles, water can be added appropriately to make the pile body with a moisture content of 45% (w / w), the waste bio-organic matter compost when the temperature of the center of the pile reaches 50±2°C, set aside;

[0035] (2) Mixed fermentation: Take 5m of waste bio-organic matter after treatment 3 with 0.1m 3 The sieved garden soil is mixed, the mixing ratio is 1:0....

Abstract

The invention discloses an organic cultivating soil and its preparation method. The moisture content of the cultivating soil is 15-30% (w/w), the ratio of carbon to nitrogen (C/N) is 15-25, the removal rate for removing pathogens, eggs and grass seeds is larger than or equal to 99%. The preparation method of the organic cultivating soil is to disinfect the soil and remove eggs and grass seeds during the high fermentation temperature period of waste biological organic compost, and comprises three processes of raw material pretreatment, mixed fermentation and aging, wherein the raw material pretreatment includes the treatment of garden soil and the treatment of waste biological organic matter. The cultivating soil provided by the invention contains multifarious nutriments which are necessary for the growth of plants, has high removal rate of pathogens, grass seeds and eggs; in addition, wastes are reused during the preparation process so as to change waste into valuables and protect environmental health.

Description

technical field [0001] The invention relates to a plant cultivation base material and a preparation method thereof, in particular to an organic cultivation soil prepared from waste biological organic matter and a preparation method thereof. Background technique [0002] At present, more and more people like to grow some green plants indoors. Not only can they beautify the environment, but a certain amount of indoor flowers and plants can also have the following advantages: indoor flowers and plants can adjust the depressed mood; indoor flowers and plants can absorb harmful and toxic substances , Purify indoor air; many plants can absorb or reduce a large amount of electromagnetic radiation produced by household appliances; many anions emitted by plants increase air humidity and enhance human immunity. Cultivation methods are divided into soil cultivation and soilless cultivation. Soilless cultivation is to use nutrient solution instead of soil for cultivation. Although soil...
