Embodiment 1
[0028] A cultivation method for improving the aroma and aroma quality of tobacco leaves, specifically comprising the following steps:
[0029] Rapeseed is planted in the tobacco field. After the rapeseed enters the green maturity period, the rapeseed stalks and rapeseeds are chopped into 10-20 cm uneven short strips, and then covered with a layer of phosphogypsum, covering 0.03-0.04t per mu. Phosphogypsum can Get it directly from the place where the waste in the fertilizer factory is piled up, and then mix the chopped rape stalks and phosphogypsum into the soil of the tobacco field to form a base fertilizer. %, sufficient water can ensure the decay of rapeseed stalks, and this step can be operated manually or by special machinery.
[0030] After 25 days of pressing greening treatment, ridges were formed in the tobacco field, and the distance between the ridges was according to the conventional spacing, and the cultivated tobacco seedlings were transplanted into the pressed gre...
Embodiment 2
[0033] Rapeseed is planted in the tobacco field. After the rapeseed enters the green maturity period, the whole rapeseed is cut into short strips with a length of 10-20 cm by machine; then the cut rapeseed is covered with a layer of phosphogypsum and phosphorus potassium slag (1:2) , Cover 0.03-0.04t per mu. If the soil moisture is insufficient, shallow irrigation should be performed until the relative moisture content is 60%-70%, and then the chopped rape straw, phosphogypsum and phosphorus-potassium slag mixture should be poured into the soil of the tobacco field. Mix with soil to form basal fertilizer.
[0034] Then in the tobacco seedling field after pressing green, the application of compound fertilizer application of pure nitrogen amount is 60% of the total nitrogen application rate, and the N:P of compound fertilizer 2 o 5 :K 2 O=1:2:3, covering 5-10 cm of soil, which can better combine rapeseed base fertilizer and compound fertilizer, balance the decomposition rate o...
Embodiment 3
[0038] Rapeseed is planted in the tobacco field. After the rapeseed enters the green maturity period, the whole rapeseed is cut into short strips with a length of 10-20 cm by machine; then the cut rapeseed is covered with a layer of phosphogypsum and phosphorus potassium residue (2:3) , Cover 0.03-0.04t per mu. If the soil moisture is insufficient, shallow irrigation should be performed until the relative moisture content is 60%-70%, and then the chopped rape straw, phosphogypsum and phosphorus-potassium slag mixture should be poured into the soil of the tobacco field. Mix with soil to form basal fertilizer.
[0039] Then, in the tobacco seedling field after green pressing, the application of compound fertilizer to use pure nitrogen amount is 65% of the total nitrogen application rate, and the N:P of compound fertilizer 2 o 5 :K 2 O=1:2:3, cover the soil of 5-10 centimeters, after 35 days of green pressing treatment, ridges are formed in the field, the width of ridges is 60c...
