Problems solved by technology

According to the current conditions of tobacco cultivation in my country, the multiple cropping index of most tobacco planting soils is relatively large. At the same time, due to the long-term application of large amounts of chemical fertilizers and the neglect of the use of organic fertilizers, the soil in tobacco fields is acidified, compacted, biological activity is reduced, and nutrients such as phosphorus and potassium are depleted. The utilization rate is not high, and it is difficult to supply the balanced and sufficient nutrition required for the growth of flue-cured tobacco, resulting in a decline in the yield and internal quality of tobacco leaves, such as lightening of color, reduction of oil content, lack of aroma, poor taste, etc.

Embodiment 1

[0051] The present invention includes the present invention is mainly prepared by the following ingredients, in parts by weight,

[0052] Corn stalks: 25 parts, livestock manure: 25 parts, oil dry: 10 parts, urea: 0.1 parts, decomposing agent: 0.1 parts.

[0053] The specific steps are:

[0054] (1) Collect straw and pig manure;

[0055] (2) For the crushing of straw, use a grinder or straw cutter to cut and crush to 3cm;

[0056] (3) Water regulation, soak the crushed corn stalks with water to make the stalks fully absorb water and keep the relative water content at 60%. The specific performance is: grab the stalks and squeeze the water with hands;

[0057] (4) The layered stacking method is adopted. Each layer is stacked with the evenly mixed straw at a thickness of 20 cm. Then, according to the amount of urea and the amount of fermentation bacteria, it is evenly sprinkled on the straw and mixed, and then the pig manure is evenly spread. The first layer of stacking is completed on the...

[0061] The present invention includes the present invention mainly prepared by the following ingredients, in parts by weight,

[0062] Corn stalks: 30 parts, livestock manure: 20 parts, oil dry: 15 parts, urea: 0.3 parts, decomposing agent: 0.1 parts.

[0063] It includes the following steps:

[0064] (1) Collect straw and cow dung;

[0065] (2) For the crushing of straw, use a crusher or straw cutter to cut and crush to 3-5cm;

[0066] (3) Water adjustment, soak the crushed corn stalks with water to make the stalks fully absorb water and keep the relative water content at 65%. The specific performance is: grab the stalks and squeeze the water out after pinching them;

[0067] (4) The layered stacking method is adopted, each layer is piled up with a thickness of 30cm with evenly mixed straw, and then it is evenly sprinkled on the straw according to the amount of urea and the amount of fermenting bacteria and mixed in, and then the cow dung is evenly spread on The first layer of stacking...

Embodiment 3

[0071] The present invention includes the present invention mainly prepared by the following ingredients, in parts by weight,

[0072] Corn stalks: 35 parts, livestock manure: 15 parts, oil dry: 10 parts, urea: 0.5 parts, decomposing agent: 0.1 parts.

[0073] The preparation method is:

[0074] (1) Collect straw and sheep dung;

[0075] (2) For the crushing of straw, use a crusher or straw cutter to cut and crush to 4 cm;

[0076] (3) Water adjustment, soak the crushed corn stalks with water to make the stalks fully absorb water and keep the relative water content at 62%. The specific performance is: grab the stalks and squeeze the water after squeezing them;

[0077] (4) The layered stacking method is adopted, each layer is stacked with the evenly mixed straw in a thickness of 25 cm, and then it is evenly sprinkled on the straw according to the amount of urea and the amount of fermenting bacteria and mixed in, and then the sheep dung is evenly spread on On the straw, the first layer o...

Abstract

The invention discloses a special compound organic fertilizer for tobacco. The special compound organic fertilizer mainly comprises the following components in parts by weight: 25-40 parts of maize straws, 10-25 parts of excrements of livestock, 10-15 parts of oil cake, 0.1-0.6 part of urea and 0.1 part of a decomposition agent. The organic fertilizer is mainly prepared by the following steps: pretreating raw materials, performing primary fermentation, performing secondary fermentation, drying and packaging. The fertilizer is applied to the ditch before tobacco plant transplanting, so that growth of the tobacco plants can be obviously promoted, particularly the plant height and leaf length are increased, and the tobacco planting soil is improved; and therefore, the nicotine content of the tobacco leaf is reduced, the quality and appearance quality of the tobacco leaf are improved, the land resources can be effectively protected due to reasonable application of the fertilizer, and a necessary guarantee is provided for sustainable development of the tobacco leaf. The organic fertilizer is particularly suitable for cultivation of high-quality tobacco leaf. In addition, the organic fertilizer disclosed by the invention is wide in source and low in price, the pollution of straw combustion and livestock manure on the environment is reduced, the preparation method is simple and feasible, and the fertilizer is wide in functions and good in effect.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a special compound organic fertilizer for tobacco and a preparation method thereof. Background technique [0002] In recent years, due to the long-term excessive use of chemical fertilizers in my country, the problems of soil degradation and decline in the quality of agricultural products have become increasingly prominent in agricultural production. According to the current conditions of tobacco cultivation in my country, the multiple cropping index of most tobacco planting soils is relatively large. At the same time, due to the long-term application of large amounts of chemical fertilizers and the neglect of the use of organic fertilizers, the soil in tobacco fields is acidified, compacted, biological activity is reduced, and nutrients such as phosphorus and potassium are depleted. The utilization rate is not high, and it is difficult to supply the balanced and sufficient nutr...
