Problems solved by technology

At present, my country mainly relies solely on the large-scale application of chemical fertilizers and pesticides to maintain high yields of tobacco leaves. However, the use of large amounts of chemical fertilizers and pesticides has caused serious damage to the soil and environment for tobacco planting, resulting in the emergence of high-quality tobacco areas in some long-term tobacco planting areas. The unbalanced enrichment and depletion of soil nutrients, the imbalance of soil nutrient supply, and the deterioration of farmland ecological environment lead to a significant decline in the quality of tobacco leaves and the benefits of tobacco planting, causing losses to tobacco growers and restricting the sustainable development of tobacco production. develop

Embodiment 1

[0029] A method for growing tobacco, specifically comprising the steps of:

[0030] Rapeseed is planted in the tobacco field. After the rapeseed enters the green maturity period, the rapeseed straw and rapeseed are cut and pressed as a whole, that is, all the rapeseed straw and rapeseed are chopped and thrown into the soil of the tobacco field to form a base fertilizer. Then, the cultivated tobacco seedlings are transplanted into the pressed tobacco fields.

[0031] Tobacco field management was carried out according to conventional methods until the tobacco leaves matured.

Embodiment 2

[0033] Rapeseed is grown in tobacco fields.

[0034] After the rapeseed enters the green maturity period, the rapeseed stalks and rapeseeds are cut and pressed, and the whole is pressed green, that is, all the rapeseed stalks and rapeseeds are chopped and thrown into the soil of the tobacco field. This step can be operated with special machinery. While chopping rape stalks and rapeseeds, they are chopped and buried in the soil, so that all rapeseed is evenly mixed with the soil of the tobacco field to form a base fertilizer.

[0035] Then, sprinkle chemical fertilizers and general calcium in the pressed green tobacco field, and then cover with a 15cm thick soil layer. In this way, the rapeseed base fertilizer and chemical fertilizer can be better combined, the decomposition rate of the rapeseed base fertilizer and the release rate of organic matter can be balanced, the retention time of base fertilizer nutrients can be extended, and the purpose of long-term and balanced fertiliz...

Embodiment 3

[0039] Rapeseed is grown in tobacco fields.

[0040] After the rapeseed enters the green maturity period, the rapeseed stalks and rapeseeds are chopped and pressed green as a whole, that is, the rapeseed straws and rapeseeds are all chopped up and poured into the soil of the tobacco field to form a base fertilizer.

[0041] Then, sprinkle chemical fertilizers and general calcium in the pressed green tobacco field, and then cover with a 15cm thick soil layer. In this way, the rapeseed base fertilizer and chemical fertilizer can be better combined, the decomposition rate of the rapeseed base fertilizer and the release rate of organic matter can be balanced, the retention time of base fertilizer nutrients can be extended, and the purpose of long-term and balanced fertilization can be achieved. The mass ratio of nitrogen, phosphorus and potassium in the chemical fertilizers applied is 10:11:25, the amount of chemical fertilizer applied per mu of tobacco field is 32 kg, and the amo...

Abstract

The present invention provides a method for planting tobaccos. The method includes the steps of planting rapes in a tobacco field, when the rapes enter into a green ripe stage, turning over rape stalks and rapeseeds integrally, and transplanting cultivated tobacco seedlings in a green manured field. The organic oil content of rapes is high, the most nutrient and organic matters that the rapes contain can be achieved in the green ripe stage, and base fertilizers obtained by turning over the rapes can evenly supply adequate nutrients for the growth of the tobaccos for a long term, so that chemical fertilizers can be greatly decreased in the process of planting tobaccos, the soil properties can be improved, and the soil environmental destruction and nutrient imbalance of tobaccos caused by single cropping of tobaccos can be avoided. The method also can improve the yield of tobacco leaves, greatly improve the aroma substance content of tobacco leaves, and improve the quality of tobacco leaves. According to the method, the yellowing speed of tobacco leaves and the single leaf mass can be increased, the proportion of superior and medium leaves, and the aroma substance content of tobacco leaves, the per mu yield, and the per mu value can be increased.

Description

technical field [0001] The invention relates to the field of tobacco, in particular to a tobacco planting method. Background technique [0002] Tobacco is one of the important economic crops in my country, and its planting area and total output both rank first in the world. At present, my country mainly relies solely on the large-scale application of chemical fertilizers and pesticides to maintain high yields of tobacco leaves. However, the use of large amounts of chemical fertilizers and pesticides has caused serious damage to the soil and environment for tobacco planting, resulting in the emergence of high-quality tobacco areas in some long-term tobacco planting areas. The unbalanced enrichment and depletion of soil nutrients, the imbalance of soil nutrient supply, and the deterioration of farmland ecological environment lead to a significant decline in the quality of tobacco leaves and the benefits of tobacco planting, causing losses to tobacco growers and restricting the ...
