Problems solved by technology

However, there are certain defects in the above method. Only by decomposing and fermenting a relatively single raw material, the site is limited and the loss of organic matter such as nitrogen fertilizer is large, and it is impossible to fully decompose and fully utilize all perishable organic matter.

Embodiment 1

[0037] The preparation method of the biological organic soil that obtains high-quality tobacco of the present embodiment may further comprise the steps:

[0038] Step (1), preparation of compost raw materials:

[0039] Composting raw materials include main materials and auxiliary materials, in which the main material is agricultural and forestry waste, and the auxiliary material is domestic animal manure or human excrement; before composting, agricultural and forestry waste is crushed;

[0040] Step (2), preparation of fermentation materials:

[0041] The compost raw materials are fully mixed according to the carbon-nitrogen ratio of 22:1 to obtain the fermentation product. At the same time, pay attention to composting straw, peanut shells, plant ash, etc., and human and animal manure separately, because the combination of the two will cause a sharp drop in nitrogen in the manure. Control the water content of the fermentation product at about 65%, keep the bottom dry during c...

Embodiment 2

[0048] The preparation method of the biological organic soil that obtains high-quality tobacco of the present embodiment may further comprise the steps:

[0049] Step (1), preparation of compost raw materials:

[0050] Composting raw materials include main materials and auxiliary materials, in which the main material is agricultural and forestry waste, and the auxiliary material is domestic animal manure or human excrement; before composting, agricultural and forestry waste is crushed;

[0051] Step (2), preparation of fermentation materials:

[0052] The compost raw materials are fully mixed according to the carbon-nitrogen ratio of 30:1 to obtain the fermentation product. At the same time, pay attention to composting straw, peanut shells, plant ash, etc., and human and livestock manure separately, because the combination of the two will cause a sharp drop in nitrogen in the manure. Control the water content of the fermentation product at about 65%, keep the bottom dry durin...

Embodiment 3

[0058] The preparation method of the biological organic soil that obtains high-quality tobacco of the present embodiment may further comprise the steps:

[0059] Step (1), preparation of compost raw materials:

[0060] Composting raw materials include main materials and auxiliary materials, in which the main material is agricultural and forestry waste, and the auxiliary material is domestic animal manure or human excrement; before composting, agricultural and forestry waste is crushed;

[0061] Step (2), preparation of fermentation materials:

[0062] The compost raw materials are fully mixed according to the carbon-nitrogen ratio of 35:1 to obtain the fermentation product. At the same time, pay attention to composting straw, peanut shells, plant ash, etc., and human and livestock manure separately, because the combination of the two will cause a sharp drop in nitrogen in the manure. Control the water content of the fermentation product at about 65%, keep the bottom dry durin...

Abstract

The invention provides a bioorganic soil for obtaining high-quality tobacco, and a preparation method thereof. The improvement effect is measured by measuring the physical structure, chemical indexes,biological indexes and the like of bioorganic soil, and recycling of agriculture, forestry and household garbage is indirectly achieved by detecting the nitrogen fixation efficiency of plants and reducing the use amount of a chemical fertilizer to a certain extent. Compared with other soil improvement methods, the method of the invention starts from two aspects of compost raw materials, fermentation materials and action objects, fully collects and performs compost decomposition of perishable agriculture and forestry waste organic matters such as dead leaves, old stalks, human and animal excrement and urine and the like in the agriculture, forestry and animal husbandry processes, so recycling of agriculture and forestry and household garbage is achieved, soil pollution is reduced to a certain degree, harms of carcinogenic substances to human are reduced, tobacco planting soil is improved, and the method has great significance in increasing the tobacco yield. The contradiction between the increasingly growing requirements of environmental protection sustainable development and limited management methods in China at the present stage can be relieved to a certain extent, the quality of tobacco plants can be improved, and the labor cost is reduced.

Description

technical field [0001] The invention belongs to the engineering technical field of comprehensive utilization of agricultural and forestry waste resources, and relates to a bio-organic soil, especially a bio-organic soil for obtaining high-quality tobacco, and a preparation method thereof. Background technique [0002] As an important economic source crop in my country, tobacco plays a huge role in promoting the national economy. Due to production needs, when planting tobacco in the traditional sense, long-term single partial application of chemical fertilizers leads to low soil organic matter content, easy waterlogging, easy drying in case of drought, and lack of various nutrients. Under the action of external factors such as irrigation or rainfall, the soil structure Destroying and hardening the soil surface makes the soil quality poor and unsuitable for crop growth, resulting in poor plant root growth. [0003] In the prior art, pig manure and garden waste (deciduous litt...
