Problems solved by technology

However, in recent years, due to the continuous planting of flue-cured tobacco in the soil, the land that was originally suitable for the growth of flue-cured tobacco has become no longer suitable for planting flue-cured tobacco; in addition, driven by interests, some tobacco areas have been planted with watermelon and Panax notoginseng for 2-4 years, resulting in these soils Soil fertility has been severely consumed, and soil nutrition is seriously unbalanced. When planting flue-cured tobacco is resumed, these soils will make it difficult for flue-cured tobacco to grow normally, or even grow wildly, resulting in a serious decline in the quality of the tobacco leaves produced
[0003] The existing methods for improving the soil for flue-cured tobacco planting mainly include crop rotation with gramineous crops, deep plowing and drying, increasing farmyard manure, soil testing and balanced fertilization, etc., but these measures have many problems, such as being unable to solve the damage to the soil structure. , the restoration of beneficial microbial communities in the soil, excess N in the soil, and even pesticide residues, heavy metal residues, etc.
To plant flue-cured tobacco in such plots, it is difficult to guarantee the quality of the tobacco leaves, let alone meet the production requirements of green organic tobacco leaves

Embodiment 1

[0046] A method for organically planting flue-cured tobacco through soil improvement, comprising the following steps:

[0047] 1) Plot selection: select plots that have been planted with flue-cured tobacco for more than 5 years or planted with watermelon and Panax notoginseng, resulting in serious land consumption and unbalanced soil nutrition; the plots mentioned are plots that are not planted with fruit trees or flowers within 500m ;

[0048] 2) Selection of flue-cured tobacco variety: choose a flue-cured tobacco variety that requires 5-8kg of pure nitrogen per mu and requires a large amount of fertilizer; the flue-cured tobacco variety is K326;

[0049] 3) Soil improvement:

[0050] A. Fallow: Leave the land selected in step (1) idle for 3 years, and prevent soil erosion; the method for preventing soil erosion is to spread annual fibrous roots, soft and juicy stems, short stems, hibiscus, etc. on the topsoil. Nitrogen, small flowers or grasses that can absorb heavy metals...

[0077] A method for organically planting flue-cured tobacco through soil improvement, comprising the following steps:

[0078] 1) Plot selection: select plots that have been planted with flue-cured tobacco for more than 5 years or planted with watermelon and Panax notoginseng, resulting in serious land consumption and unbalanced soil nutrition; the plots mentioned are plots that are not planted with fruit trees or flowers within 500m ; The fruit tree is a walnut tree;

[0079] 2) Selection of flue-cured tobacco variety: choose a flue-cured tobacco variety that requires 5-8kg of pure nitrogen per mu and requires a large amount of fertilizer; the flue-cured tobacco variety mentioned is Yunyan 87;

[0080] 3) Soil improvement:

[0081] A. Fallow: Leave the plot selected in step (1) idle for 4 years, and prevent soil erosion; the method for preventing soil erosion is to cover the plot with a layer of crop straw with a thickness of 5cm to keep moisture or spread it on the topsoil ...

Embodiment 3

[0092] A method for organically planting flue-cured tobacco through soil improvement, comprising the following steps:

[0093] 1) Plot selection: select plots that have been planted with flue-cured tobacco for more than 5 years or planted with watermelon and Panax notoginseng, resulting in serious land consumption and unbalanced soil nutrition; the plots mentioned are plots that are not planted with fruit trees or flowers within 500m ; The fruit tree is an apple tree;

[0094] 2) Selection of flue-cured tobacco varieties: select flue-cured tobacco varieties that require 5-8kg of pure nitrogen per mu and require a large amount of fertilizer; the flue-cured tobacco varieties are one or more of KRK26.

Abstract

The invention discloses an organic planting method for flue-cured tobacco obtained after soil improvement. The planting method comprises the steps of 1 field plot selection, 2 flue-cured tobacco variety selection, 3 soil improvement and 4 flue-cured tobacco planting. Due to the comprehensive soil improvement mode of fallowing, shallow ploughing and deep ploughing, the purpose of effectively improving the deteriorated soil is achieved, the land soil structure, beneficial microbial communities and nutrient balance are better improved, the problems of original growth imbalance, nutrient imbalance, tobacco leaf quality decrease and the like are solved due to the planted flue-cured tobacco, tobacco plants grow well, and the tobacco leaf yield and quality are obviously improved. No chemical fertilizer or chemical pesticide is needed in the whole process, the field production and management mode is adopted, the produced flue-cured tobacco is good in growth and development in the whole growing period, and tobacco leaves are delicate and pretty and have little diseases.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco planting, and in particular relates to a soil-improved organic planting method of flue-cured tobacco. Background technique [0002] Due to its unique geographical climate and good natural environment, Yunnan has always been a traditional planting area for flue-cured tobacco. However, in recent years, due to the continuous planting of flue-cured tobacco in the soil, the land that was originally suitable for the growth of flue-cured tobacco has become no longer suitable for planting flue-cured tobacco; in addition, driven by interests, some tobacco areas have been planted with watermelon and Panax notoginseng for 2-4 years, resulting in these soils Soil fertility has been severely consumed, and soil nutrition is seriously unbalanced. When flue-cured tobacco is planted again, these soils will make it difficult for flue-cured tobacco to grow normally, or even grow wildly, resulting in a ser...
