Problems solved by technology

At present, the cultivation of tobacco crops in my country mainly relies solely on the large-scale application of chemical fertilizers and pesticides to maintain high yields of tobacco leaves, resulting in serious deterioration of the soil environment, and continuous cropping obstacles have become one of the key factors restricting the tobacco planting industry in Yunnan and even the whole country
Continuous cropping of flue-cured tobacco will lead to increased soil nutrient residues, enriched salt, and decreased soil carbon and nitr

Embodiment 1

[0022] (1) Preparation of organic fertilizer:

[0023] The organic fertilizer is composed of 30% cow dung, 20% oil rot, 20% bacterial bag, 20% straw, and 10% phosphorus element, and add appropriate amount of Bacillus subtilis, Trichoderma, and actinomycetes at a temperature of 65-70°C and a humidity of 60°C Ferment for 20 days under the condition of -65% to get the special organic fertilizer for tobacco;

[0024] (2) Preparation of carbon-based biological enzyme fertilizer:

[0025] Use 45% of the organic fertilizer made above, mix the same amount of 45% biochar and 10% enzyme; after the biochar and organic fertilizer are evenly mixed, spray the enzyme with a spray method, and stir while spraying until uniform Mix and keep the temperature at 65-70°C and the humidity at 60-65% to ferment for 25 days to get the carbon-based bio-enzyme fertilizer.

Embodiment 2

[0027] Control group 1: use common organic fertilizer as fertilizer, carry out continuous cropping flue-cured tobacco on the ground of planting flue-cured tobacco, and carry out corresponding data monitoring, take the average value;

[0028] Control group 2: use ordinary organic fertilizer as fertilizer, spray 10% of environmental protection enzymes, keep the temperature at 65-70°C and humidity at 60-65% for 25 days, and carry out continuous cropping of flue-cured tobacco on the ground where flue-cured tobacco has been planted. Above-mentioned fertilizer, and carry out corresponding data monitoring, take average value;

[0029] Control group 3: use ordinary organic fertilizer as fertilizer, and apply 0.1% of Bacillus subtilis, Trichoderma, and actinomycetes to carry out continuous cropping of flue-cured tobacco on the ground where flue-cured tobacco has been planted, apply the above fertilizer, and carry out corresponding data monitoring, and take the average value ;

Abstract

The invention belongs to the field of agricultural planting, and particularly relates to a carbon-based bio-enzyme fertilizer capable of resisting continuous cropping obstacles of flue-cured tobacco.The carbon-based bio-enzyme fertilizer comprises an organic fertilizer, biochar and enzymes, wherein the organic fertilizer is composed of cow dung, oil cakes, fungus bags, straw, phosphorus and beneficial bacteria. The carbon-based bio-enzyme fertilizer applied to acid red soil and used for resisting the continuous cropping obstacles of flue-cured tobacco in the invention can provide medium and trace elements required by tobacco growth, adsorb toxic and harmful substances in soil, inhibit the activity of harmful flora in the soil, increase the number of beneficial flora, improve soil fertility and enhances the physical and chemical properties of the soil, and enables the soil to become loose and fertile, thereby improving the disease resistance, yield and quality of tobacco.

Description

technical field [0001] The invention belongs to the field of agricultural planting, and in particular relates to a carbon-based bio-enzyme fertilizer resistant to continuous cropping obstacles of flue-cured tobacco. Background technique [0002] Special fertilizer for crops is a fertilizer specially used for crops in this area by scientifically proportioning nutrients such as nitrogen, phosphorus, potassium, and medium and trace elements according to the regional soil conditions and the characteristics of the crops' fertilizer needs. The special fertilizer for crops is developed and produced according to the law of crop growth and development and the absorption of different elements. Through the analysis of the characteristics of soil nutrient content, according to the law of fertilizer demand of different crops, combined with the local customary fertilization level, farming system and natural climate conditions, Develop special compound fertilizers for various crops accordi...
