Problems solved by technology

The application of organic fertilizers is an effective way to improve tobacco fields, but the existing organic fertilizers are slow in fertilizer efficiency, difficult to meet the nutritional needs of tobacco in the current season, and have limited effects on promoting growth and disease resistance of tobacco crops, so they are urgently needed in tobacco cultivation and production. There is a need for a growth-promoting and disease-resistant bio-organic fertilizer that can be used exclusively for tobacco crops

Embodiment 1

[0028] A special growth-promoting and disease-resistant bio-organic fertilizer for tobacco is prepared by the following steps:

[0029] (1) Take cow manure, add crop straw (corn straw with a length of 2 to 3 cm) and humic acid to adjust the livestock and poultry manure to a moisture content of 54 to 56%, and a carbon-to-nitrogen ratio of 27 to 28; because fresh livestock and poultry manure Generally, the water content is high and the carbon-to-nitrogen ratio is low. Adjusting the water content, C / N ratio, and aeration before fermentation can effectively increase the fermentation speed and prevent odor; the livestock and poultry manure, humic acid, and crop straw The weight ratio between them is 7:2:1.

[0030] (2) Evenly mix an appropriate amount of organic fertilizer fermentation bacteria (ZK decomposing agent fermentation bacteria, the addition amount is 200 g / ton of material) into the material obtained in step (1), and carry out composting fermentation to further increase t...

Embodiment 2

[0034] A special growth-promoting and disease-resistant bio-organic fertilizer for tobacco is prepared by the following steps:

[0035] (1) Take cow manure, add crop straw (corn stalks with a length of 2-3cm) and humic acid to adjust the livestock and poultry manure to a moisture content of 50-53% and a carbon-to-nitrogen ratio of 25-27; because fresh livestock and poultry manure Generally, the water content is high and the carbon-to-nitrogen ratio is low. Adjusting the water content, C / N ratio, and aeration before fermentation can effectively increase the fermentation speed and prevent odor; the livestock and poultry manure, humic acid, and crop straw The weight ratio between them is 7:1.8:1.

[0036] (2) Evenly mix an appropriate amount of organic fertilizer fermentation bacteria (ZK decomposing agent fermentation bacteria, the addition amount is 200 g / ton of material) into the material obtained in step (1), and carry out composting fermentation to further increase the ferment...

Embodiment 3

[0040] A special growth-promoting and disease-resistant bio-organic fertilizer for tobacco is prepared by the following steps:

[0041] (1) Take cow manure, add crop straw (wheat straw with a length of 2-3cm) and humic acid to adjust the livestock and poultry manure to a moisture content of 56-60% and a carbon-to-nitrogen ratio of 28-30; because fresh livestock and poultry manure Generally, the water content is high and the carbon-to-nitrogen ratio is low. Adjusting the water content, C / N ratio, and aeration before fermentation can effectively increase the fermentation speed and prevent odor; the livestock and poultry manure, humic acid, and crop straw The weight ratio between them is 8:2:1.

[0042] (2) Evenly mix the organic fertilizer fermentation bacteria (ZK decomposing agent fermentation bacteria, the addition amount is 200 g / ton of material) into the material obtained in step (1), and carry out composting fermentation to further improve the fermentation speed and rapidi...

Abstract

The invention relates to a preparation method for a bio-organic fertilizer special for promoting growth and resisting disease of tobacco. The method comprises the following steps: (1) taking excrements of livestock, adding crop straws and humic acid and adjusting the moisture content of the excrements of livestock to 50-60% and the carbon nitrogen ratio at 25-30; (2) uniformly doping a defined amount of organic fertilizer zymophyte into the acquired materials, performing compost fermentation, measuring the temperature in material stack every day, periodically stirring, increasing the temperature to 55-65 DEG C and maintaining for 5-7 days; (3) uniformly doping a defined amount of compound microbial agent into the acquired material, stacking to the height above 1m, stirring for one time per week, maintaining the moisture content at 35-45% and fermenting for 20-30 days; (4) airing the acquired materials till the moisture content below 30%, and then screening, thereby acquiring the powder, namely, the bio-organic fertilizer special for promoting growth and resisting disease of tobacco. The bio-organic fertilizer can optimize the release of the soil nutrient, can obviously promote the growth and development of tobacco strains, can obviously relieve the happening of tobacco diseases and can improve the tobacco quality.

Description

technical field [0001] The invention relates to a special fertilizer for tobacco, in particular to a preparation method of a special growth-promoting and disease-resistant biological organic fertilizer for tobacco. Background technique [0002] Henan Province is a large province of livestock and poultry breeding, and the annual output of livestock and poultry breeding manure reaches 200 million tons. If a large amount of livestock manure is not disposed of properly, it will pose a serious threat to the environment around the farm. As we all know, livestock and poultry manure is rich in nitrogen, phosphorus, potassium and trace elements and other nutrients. After aerobic fermentation and harmless treatment, it can be turned into high-quality organic fertilizer and returned to the field for utilization. One of the effective ways can not only make full use of the nutrient resources in the livestock and poultry waste, but also solve the problem of environmental pollution in the...
