Problems solved by technology

On the one hand, due to the one-sided pursuit of high output and high output value, some places blindly increase the amount of fertilization year by year, resulting in excessively large and thick tobacco leaves, which affect the aroma and taste, and reduce the availability of tobacco leaves; on the other hand, some tobacco fields Extensive cultivation, insufficient fertilization, and premature senescence of tobacco plants
[0003] Second, the method of fertilization is unscientific and unreasonable
Mainly manifested in excessive fertilization times, unreasonable ratio of nitrogen, phosphorus, and potassium, excessive fertilizer loss caused by watering, shallow fertilization, and soaking the field after planting, low fertilizer utilization rate, increased cost, and polluted the environment
Three fertilization time is not timely
[0004] Fourth, the location of fertilization is unscientific

Embodiment 1

[0016] Embodiment one: a kind of flue-cured tobacco double-layer fertilization method, the steps of the present invention are:

[0017] 1) After the tobacco field is leveled, draw a line according to 115cm, and apply 30 kg of tobacco base fertilizer in double rows in the middle of the lined tobacco moisture on a per mu basis. The weight ratio of the tobacco base fertilizer formula is N:P:K: B:Mg=7:13:13:1:7; the depth of fertilization is 5cm;

[0018] 2) When planting tobacco, apply 5 kg of the above-mentioned tobacco base fertilizer in circular ponds or mixed ponds per mu of tobacco land; the fertilization depth is 5 cm;

[0019] 3) After planting tobacco, cover the pond with 1.0 kg of nutrient soil for each pond; the nutrient soil is obtained by composting and fermenting farmyard manure;

[0020] 4) After transplanting, apply 20 kg of tobacco topdressing fertilizer per mu. The weight ratio of the tobacco topdressing fertilizer formula is N:P:K:B=9.5:0:30:1; the fertilizatio...

Embodiment 2

[0022] Embodiment two: a kind of flue-cured tobacco double-layer fertilization method, the steps of the present invention are:

[0023] 1) After the tobacco field is leveled, draw a line according to 125 cm, and apply 35 kg of tobacco base fertilizer in double rows in the middle of the lined tobacco moisture on a per mu basis. The weight ratio of the tobacco base fertilizer formula is N:P:K : B:Mg=13:23:23:4:13; the depth of fertilization is 8 cm;

[0024] 2) When planting tobacco, apply 11 kg of the above-mentioned tobacco base fertilizer in circular ponds or mixed ponds per mu of tobacco land; the fertilization depth is 8 cm;

[0025] 3) After planting tobacco, cover each pond with 1.5 kg of nutrient soil; the nutrient soil is fermented from farmyard manure;

[0026] 4) After transplanting, apply 25 kg of tobacco topdressing fertilizer per mu. The weight ratio of the tobacco topdressing fertilizer formula is N:P:K:B=15.5:3:36:6; the fertilization depth is 3cm.

Embodiment 3

[0028] Embodiment three: a kind of flue-cured tobacco double-layer fertilization method, the steps of the present invention are:

[0029] 1) After the tobacco field is leveled, draw a line according to 120cm, and apply 33 kg of tobacco base fertilizer in two rows in the middle of the lined tobacco moisture on a per mu basis. The weight ratio of the tobacco base fertilizer formula is N:P:K: B:Mg=10:18:18:1:10; the depth of fertilization is 6cm;

[0030] 2) When planting tobacco, apply 8 kg of the above-mentioned tobacco base fertilizer in circular ponds or mixed ponds per mu of tobacco land; the fertilization depth is 6cm;

[0031] 3) After planting tobacco, cover the pond with 1.25 kg of nutrient soil for each pond; the nutrient soil is obtained by composting and fermenting farmyard manure;

[0032] 4) After transplanting, apply 20 kg of tobacco topdressing fertilizer per mu. The weight ratio of the tobacco topdressing fertilizer formula is N:P:K:B=12.5:2:33.5:3; the fertiliz...

Abstract

The invention discloses a double-layer flue-cured tobacco fertilization method. The double-layer flue-cured tobacco fertilization method comprises the following steps of: (1) flattening a cigarette field, marking according to 115-125cm, taking each mu as a unit, applying 30-35kg of tobacco base fertilizers in double rows in the middle of the marked cigarette field, wherein the fertilization depth is 5-8cm, arranging the ridges and forming a pond after the fertilizers are applied; (2) applying 5-11kg of the tobacco base fertilizers on an annular pond or a mixed pond in the smoke field in each mu in the process of planting the tobaccos, wherein the fertilization depth is 5-8cm; (3) covering the pond covered soil by using 1.0-1.5kg of nutrient soil in each pond after the operation of planting the tobaccos, wherein the nutrient soil is obtained by stacking and fermenting the farmyard manure; and (4) applying 20-25g of tobaccos to topdressing in each mu after transplanting, wherein the fertilization depth is 1-3cm. The method has the beneficial effects that compared with the traditional flue-cured tobacco fertilization technology, the technical method has the advantages that the fertilizer utilization rate can be improved, the tobacco leaf quality is improved, and the economic benefits are obvious.

Description

technical field [0001] The technical invention relates to a fertilizer application method in flue-cured tobacco cultivation, especially a double-layer fertilizer application method. Background technique [0002] Although the flue-cured tobacco fertilization level in our state has been greatly improved in recent years, there are still problems of unbalanced flue-cured tobacco fertilization level and large blindness, which are mainly manifested in: First, the unbalanced fertilization amount. On the one hand, due to the one-sided pursuit of high output and high output value, some places blindly increase the amount of fertilization year by year, resulting in excessively large and thick tobacco leaves, which affect the aroma and taste, and reduce the availability of tobacco leaves; on the other hand, some tobacco fields Extensive tillage means insufficient fertilization and premature senescence of tobacco plants. [0003] Second, the method of fertilization is unscientific and u...
