Embodiment 1

[0030] The compost product for improving tobacco planting soil is prepared by the following method:

[0031](1) Preparation of fermented materials: garden wastes (dead branches and leaves) are pulverized. After pulverization, at least 75% of the raw materials have a particle size of <3 cm; the total nitrogen and total carbon contents of cow dung and dead branches and leaves are measured respectively. Cow dung and garden waste are uniformly mixed according to C / N=25:1 to obtain fermented materials, and the moisture content of the fermented materials is controlled at 50%-60%; the sources of raw materials are widely available and the cost is low.

[0032] (2) Aerobic composting fermentation: maintain the water content of the fermentation heap during the composting process to be 50-60%; turn over once every 7 days to ensure that the composting process is aerobic fermentation, and carry out temperature measurement to the composting fermentation regularly every day, and A high tempe...

Embodiment 2

[0044] Different from Example 1, the compost product used to improve tobacco planting soil was prepared by the following method:

[0045] (1) Preparation of fermented materials: uniformly mix chicken manure and garden waste according to C / N=28:1 to obtain fermented materials, and control the water content of fermented materials at 50%-60%.

[0046] (2) Aerobic composting fermentation: During the composting process, the water content of the fermentation heap is maintained at 50-60%; the temperature in the high temperature period is 50°C-70°C.

[0047] (3) One-time inoculation: when the heap body enters the cooling period, carry out one-time inoculation fermentation on the 13th to 15th day of composting, and insert Trametes versicolor; the density of Trametes versicolor is: Trametes versicolor (1.2 × 10 10 CFU) / kg wet material.

[0048] (4) Secondary inoculation: carry out secondary inoculation fermentation on the 25th-30th day of composting, insert Bacillus amyloliquefaciens a...

Embodiment 3

[0052] Different from Example 1, the compost product used to improve tobacco planting soil was prepared by the following method:

[0053] (1) Preparation of fermented materials: uniformly mix pig manure and garden waste according to C / N=30:1 to obtain fermented materials, and control the water content of fermented materials at 50%-60%.

[0054] (2) Aerobic composting fermentation: During the composting process, the water content of the fermentation heap is maintained at 50-60%; the temperature in the high temperature period is 50°C-70°C.

[0055] (3) One-time inoculation: when the heap body enters the cooling period, carry out one-time inoculation fermentation on the 13th to 15th day of composting, and insert Trametes versicolor; the density of Trametes versicolor is: Trametes versicolor (1.3 × 10 10 CFU) / kg wet material.

[0056] (4) Secondary inoculation: carry out secondary inoculation fermentation on the 25th-30th day of composting, insert Bacillus amyloliquefaciens and B...

Abstract

The invention provides a composting product for improving tobacco planting soil aiming at the problem that the tobacco planting soil is worsened, and a method for improving the tobacco planting soil by utilizing the composting product so as to improve the quality of the tobacco planting soil. According to the composting product provided by the invention, cow manure, chicken manure, pig manure andgarden wastes (crushed dry branches and fallen leaves) are mixed according to a certain initial carbon-nitrogen ratio; then humus formed by composting fermentation and ageing and the tobacco plantingsoil are mixed; in a composting process, a strain with a lignocellulose and tobacco root secretion degradation capability is inoculated and the tobacco planting soil is improved, so that the quality of the tobacco planting soil is improved and the yield of tobaccos is improved. Compared with other soil improvement methods, resource utilization of the garden wastes and livestock and poultry manureis realized; meanwhile, the tobacco planting soil is improved; the composting product has important significance on the increasing of the yield of the tobaccos.

Description

technical field [0001] The invention belongs to the field of agriculture, and specifically relates to the improvement of tobacco soil, in particular to a method for improving the quality of tobacco planting soil by using compost products to improve tobacco planting soil. Background technique [0002] Tobacco is an important economic crop, which plays a huge role in supporting my country's national economy. Continuous cropping is common in tobacco production, and continuous cropping leads to the depletion and uneven enrichment of soil nutrients in tobacco planting, resulting in the imbalance and deterioration of soil nutrients, which in turn affects the absorption of soil nutrients by tobacco. In addition, the transpiration rate of continuous cropping tobacco decreases, photosynthesis weakens, and the potassium content of plants decreases, which has adverse effects on tobacco growth. What's more serious is that continuous cropping will not only inhibit the growth of tobacco,...
