Problems solved by technology

However, an important problem in the application of green manure in flue-cured tobacco production at present is that green manure decomposes slowly in the tobacco field after overturning, and the nutrients are concentrated and released in the later stage, which does not match the fertilization requirements of nitrogen control in the later stage of flue-cured tobacco growth to improve the quality of tobacco leaves.
Another method is to use microbial fertilizers to improve the soil in tobacco fields and improve the quality of tobacco leaves, but if the amount of microbial fertilizers is small, the effect will not be obvious, and if the amount is large, the cost will be high
At present, there is no report on the compound application of green manure, decomposing agent and microbial fertilizer to improve soil and improve the yield and quality of flue-cured tobacco

Embodiment 1

[0013] In Fengjie County, Chongqing City, ryegrass was sown after the flue-cured tobacco was harvested in late September and the tobacco stems were pulled out. The ryegrass was harvested in early April of the following year, cut into 10-20cm sections, and spread evenly on the tobacco row, and then used the day before. A water-activated decomposer is sprayed or poured on ryegrass. The decomposing agent used is the "Rui Laite" brand straw rotting agent produced by Chengdu Synthetic Biotechnology Co., Ltd., and the dosage is 5 g / mu. Commercial microbial fertilizer and tobacco-specific compound fertilizer were added to the base fertilizer. The microbial fertilizer used is the "Lazy Dragon Brother" brand compound microbial fertilizer produced by Chongqing Lvhuan Biological Engineering Co., Ltd., with an amount of 30 Kg / mu; the nitrogen, phosphorus, and potassium ratio of the tobacco-specific compound fertilizer is 7:12:25, and the amount is 30 Kg / mu. Then press the green manure a...

Embodiment 2

[0015] In the experimental farm of Southwest University in Beibei District, Chongqing, the flue-cured tobacco was harvested in late September and the tobacco stems were pulled out. Broad beans were sown in early October. The broad bean plants were pulled out in early April of the following year, cut into 10-20cm sections, and spread evenly on the tobacco rows. , and then spray or pour the decomposing agent activated with manure the day before on the broad bean plants. The decomposing agent used is the "Rui Laite" brand straw rotting agent produced by Chengdu Synthetic Biotechnology Co., Ltd., and the dosage is 5 g / mu. Commercial microbial fertilizer and tobacco-specific compound fertilizer were added to the base fertilizer. The microbial fertilizer used is the "Lazy Dragon Brother" brand compound microbial fertilizer produced by Chongqing Lvhuan Biological Engineering Co., Ltd., with an amount of 30 Kg / mu; the nitrogen, phosphorus, and potassium ratio of the tobacco-specific c...

Embodiment 3

[0017] In Pengshui County, Chongqing City, ryegrass is sown after the flue-cured tobacco is harvested in mid-September and the tobacco stems are pulled out. The ryegrass is harvested in early April of the following year, cut into 10-20cm sections, and spread evenly on the tobacco row, and then used the day before. The manure-activated decomposer is sprayed or poured on the ryegrass. The decomposing agent used is the "Rui Laite" brand straw rotting agent produced by Chengdu Synthetic Biotechnology Co., Ltd., and the dosage is 5 g / mu. Commercial microbial fertilizer and tobacco-specific compound fertilizer were added to the base fertilizer. The microbial fertilizer used is the "Lazy Dragon Brother" brand compound microbial fertilizer produced by Chongqing Lvhuan Biological Engineering Co., Ltd., with an amount of 30 Kg / mu; the nitrogen, phosphorus, and potassium ratio of the tobacco-specific compound fertilizer is 7:12:25, and the amount is 30 Kg / mu. Then press the green manur...

Abstract

The invention provides a method for increasing yield and improving quality of continuously cropped flue-cured tobacco. The method combines planting and turning over and pressing green manure with applying decomposing agents and microbial fertilizer. When the green manure is turned over and pressed in spring, the decomposing agents are applied; a base fertilizer includes both special tobacco compound fertilizer and the microbial literalizer, so that green manure can give a full play in improving the soil, increasing yield and improving quality of tobacco. Therefore, the method is a simple, effective and practical method for increasing yield and improving quality of the continuously cropped flue-cured tobacco leaves. The yield of the tobacco leaves is increased by 15.2%-19.8%, both the appearance quality and the internal quality of tobacco leaves are improved, and the high and intermediate-grade tobacco yield is increased by 7.5%-10.5%.

Description

technical field [0001] The invention relates to the technical field of tobacco cultivation, in particular to the field of flue-cured tobacco cultivation, in particular to a method for improving the yield and quality of flue-cured tobacco in continuous cropping. Background technique [0002] Flue-cured tobacco is a non-continuous crop. With the prolongation of flue-cured tobacco continuous cropping years, the physical and chemical properties of tobacco field soil and soil biological environment will often deteriorate to varying degrees, which will have a negative impact on the yield and quality of flue-cured tobacco leaves. In order to avoid continuous cropping obstacles, one of the methods is to rotate flue-cured tobacco with other crops in the tobacco planting area, such as planting flue-cured tobacco for one or two years, then planting corn for one or two years in the same plot, and then planting flue-cured tobacco in the plot . However, since flue-cured tobacco is mostly...
