Problems solved by technology

[0003] However, the distribution of cinnabar tobacco is sporadic in Yunnan Province, and there is no stable source of cinnabar tobacco leaf raw materials in our province. In addition, there is still a large research gap in the field fertilization management of cinnabar tobacco. When tobacco farmers plant cinnabar tobacco, they often follow conventional tobacco planting methods. Fertilization management in the field has resulted in a low proportion of cinnabar tobacco, large differences in the quality of cinnabar tobacco, and many other problems, which will bring greater difficulties to the future product development and order production of cinnabar tobacco, and seriously affect the high-quality cinnabar tobacco industry. High-end brands healthy growth

Embodiment 1

[0023] A. Base fertilizer application: fully mix HM decomposing agent with 75 times of straw and oily rice bran, evenly sprinkle on fresh pig manure, and adjust the water content to 50%. The processed farmyard manure is stacked naturally, and the surface of the fermentation pile is covered with a worn-out plastic film, leaving 25cm uncovered at the bottom, and the decomposed farmyard manure is obtained after natural fermentation for 18 days. 20 days before the tobacco seedlings were transplanted, 420 kg / ha of tobacco-specific compound fertilizer (N:P:K=1:1:3) and 18,000 kg / ha of decomposed farmyard manure were mixed, and combined with ridges and buckled into the bottom of the ridges.

[0024] B. Topdressing fertilizer application: 15d (rooting stage), 35d (pre-growth stage), 50d (middle-growth stage) after transplanting, apply tobacco-specific compound fertilizer in 3 times (N:P:K=1:1: 3. The amount of nitrogen application is 72kg / hm 2 )720kg / hm 2 and 35 kg 51% potassium sul...

[0026] A. Base fertilizer application: fully mix HM decomposing agent with 60 times of straw and oily rice bran, evenly sprinkle on fresh chicken manure, and adjust the water content to 55%. The processed farmyard manure is stacked naturally, and the surface of the fermentation pile is covered with a worn-out plastic film, leaving 20cm uncovered at the bottom, and the decomposed farmyard manure is obtained after natural fermentation for 20 days. 17 days before transplanting tobacco seedlings, 360 kg / ha of tobacco-specific compound fertilizer (N:P:K=1:1:2.5) and 16,000 kg / ha of decomposed farmyard manure were mixed, and combined with ridges and buckled into the bottom of the ridges.

[0027] B. Topdressing fertilizer application: 18d (rooting stage), 34d (pre-growth stage), 55d (middle-stage of flourishing growth) topdressing tobacco-specific compound fertilizer in 3 times (N:P:K=1:1:2.5, nitrogen amount 54kg / hm 2 )540kg / hm 2 and 33kg of 51% potassium sulfate, the ratio of th...

Embodiment 3

[0029] A. Base fertilizer application: fully mix HM decomposing agent with 90 times of straw and oily rice bran, evenly sprinkle on fresh cow dung, and adjust the water content to 60%. The treated farmyard manure is stacked naturally, and the surface of the fermentation pile is covered with a worn-out plastic film, leaving 30cm uncovered at the bottom, and the decomposed farmyard manure is obtained after natural fermentation for 22 days. 18 days before transplanting tobacco seedlings, 480kg / ha of tobacco-specific compound fertilizer (N:P:K=1:1:3) and 14,000kg / ha of decomposed farmyard manure were mixed, and combined with ridging and buckling into the bottom of the ridge.

[0030] B. Topdressing fertilizer application: 20d (rooting stage), 40d (prosperous growth stage), 60d (prosperous growth stage) 3 times topdressing special compound fertilizer for tobacco (N:P:K=1:1:3, nitrogen amount 63kg / hm 2 )630kg / hm 2 and 30kg of 51% potassium sulfate, and the ratio of three topdressi...

Abstract

The invention discloses a fertilizing method for increasing cherry-red tobacco proportion through co-application of iron, manganese and magnesium. The method specifically comprises the following stepsthat A, base fertilizer application is carried out, specifically, 17-20 days before cherry-red tobacco transplanting, special compound fertilizer for tobacco and decomposed farmyard manure are applied in a mixed mode and are buckled into the bottoms of ridges by combining ridging, wherein the application amount of the special compound fertilizer for the tobacco is 360-480 kg / ha, and the application amount of the farmyard manure is 12000-18000 kg / ha; and B, topdressing application is carried out, specifically, topdressing comprises common chemical fertilizer topdressing and medium trace element fertilizer topdressing, and topdressing of 540-720 kg / hm<2> of the special compound fertilizer for the tobacco and 30-35 kg of 51% potassium sulfate is carried out for three times 15-60 d after cherry-red tobacco transplanting; and topdressing of 30-36 mg of iron fertilizer, 18-24 g of magnesium fertilizer and 40-60 mg of manganese fertilizer is carried out for each tobacco plant 60-70 d after cherry-red tobacco transplanting. The method has the advantages that the problem of the sensitivity of cherry-red tobacco to the iron fertilizer, the manganese fertilizer and the magnesium fertilizer can be effectively solved, the conversion of nicotine in cherry-red tobacco leaves can be promoted, the cherry-red tobacco proportion can be increased, and the blank of field fertilization management of the cherry-red tobacco can be filled up.

Description

technical field [0001] The invention belongs to the technical field of tobacco cultivation, and in particular relates to a fertilization method for increasing the proportion of cinnabar smoke by co-fertilizing iron, manganese and magnesium. Background technique [0002] Cinnabar tobacco refers to tobacco leaves that are dark red and brownish-red in color after roasting, and there are small cinnabar red particles on the red spots when you see and touch it. It is called "Cherry-Red" tobacco abroad. Due to the gene mutation of cinnabar tobacco under the action of some ecological factors, nicotine (nicotine) demethylation occurs, and a large amount of nicotine is converted into demethyl nicotine, that is, nornicotine, resulting in nornicotine accounting for the total alkaloids The nicotine alkaloid content is only about 40%, and some are less than 10%. Because the total nicotine of cinnabar tobacco is equivalent to that of normal tobacco leaves, low in nicotine, and high in nor...
