Embodiment

[0039] Embodiment: the present invention optimizes fertilization test

[0040] First decomposed farmyard manure 800kg / 667m 2 , oil dry 20kg / 667m 2 Apply evenly into the shallow ditch and form a ridge, and then apply calcium ammonium nitrate 33kg / 667m 2 , Potassium dihydrogen phosphate 15.4kg / 667m 2 , Potassium sulfate 29.7kg / 667m 2 After mixing with all the medium and micro fertilizers, evenly apply it to the tobacco seedlings at 8-10cm as a base fertilizer, and then dissolve 1.5kg of ammonium bicarbonate in clear manure water as root water to irrigate the tobacco seedlings; 15 days after transplanting, add potassium sulfate 4kg / 667m 2 And calcium ammonium nitrate 6kg / 667m 2 Soluble in clear manure water to irrigate tobacco seedlings as fertilizer for pulling out seedlings; 28 days after transplanting, add calcium ammonium nitrate 16kg / 667m 2 And potassium sulfate 17kg / 667m 2 After mixing, apply the ring to the 8-10cm of the tobacco seedlings.

Abstract

The invention discloses a method for applying fertilizers to burley tobaccos. The method is characterized by (1) base fertilizers; (2) rooting fertilizers; (3) seedling picking fertilizers: 10-15 days after transplanting, 3-5kg of potassium sulfate and 5-7kg of calcium ammonium nitrate are taken as the seedling picking fertilizers per mu and the seedling picking fertilizers are dissolved into clear liquid manure to water the tobacco seedlings; and (4) additional fertilizers: 25-30 days after transplanting, 15-19kg of calcium ammonium nitrate and 16-18kg of potassium sulfate are taken as the additional fertilizers per mu, after the calcium ammonium nitrate and the potassium sulfate are uniformly mixed, the mixture is circularly applied 8-10cm away from the two sides of the tobacco plants in combination with membrane uncovering and earth is timely covered. The method has the following beneficial effects: the burley tobaccos look neat and delicate in the fields and grow well and vigorously; the yield is basically stable; the production value is increased by 6.4%; the proportion of the middle and superior tobacco leaves is increased by 12.5%; the appearance quality of the tobacco leaves is improved; and the tobacco leaves have bright color, are lustrous and full and have enough elasticity.

Description

technical field [0001] The invention relates to a method for fertilizing burley tobacco, in particular to a method for fertilizing Dabai No. 1, a variety of burley tobacco. Background technique [0002] Burley tobacco originates in the United States, and as an important raw material for producing blended cigarettes, it has high economic value. Compared with flue-cured tobacco, Burley tobacco has a large nitrogen demand, which is about three times that of flue-cured tobacco. Therefore, in actual production, due to the lack of scientific fertilization guidance, tobacco farmers use a large amount of nitrogen fertilizer in pursuit of high yield, ignoring the combined application of other nutrients, which makes the nitrogen, phosphorus, and potassium nutrient content in the tobacco field unbalanced, which will not only cause chemical composition in the tobacco leaves. , especially the high nicotine content and low nitrogen-alkaline ratio; strong and irritating smoke when smoking...
