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 bio-organic soil for obtaining high-quality tobacco and a preparation method thereof. The invention measures the improvement effect by measuring the physical structure, chemical index and biological index of the bio-organic soil, and at the same time measures the nitrogen fixation efficiency of the plant and reduces the use of chemical fertilizers to a certain extent, and indirectly solves the resources of agriculture, forestry and domestic waste. utilization. Compared with other soil improvement methods, the present invention starts with composting raw materials, fermented materials and action objects at the same time, not only fully collects perishable agricultural and forestry waste organic matter such as dead leaves and old stems, human and animal excrement and urine in the process of agriculture, forestry and animal husbandry for composting and decomposing The treatment has realized the resource utilization of agricultural, forestry and domestic waste, reduced soil pollution to a certain extent, reduced the harm of carcinogens to human beings, and improved the soil for tobacco planting, which is of great significance to the increase of tobacco production. It can not only alleviate the contradiction between the growing demand for environmental protection and sustainable development in my country at the present stage and the limited management methods to a certain extent, but also improve the quality of tobacco plants and reduce labor costs at the same time.

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...
