Problems solved by technology

[0003] Although a reasonable combination of organic fertilizer and inorganic fertilizer can promote the growth and development of crops, improve crop yield and quality, but the type of organic fertilizer and the proportion of different application will bring about different effects, and scientific experiments must be carried out. Research-based combination of organic and inorganic fertilizers can be applied in agricultural production
[0004] At present, many invention patents have been obtained in the field of organic-inorganic compound fertilizers in China, but in the domestic invention patents related to organic-inorganic compound fertilizers, there are shortcomings of extensive organic fertilizer materials and insufficient nutritional components, especially for the nutrition of flue-cured tobacco, a special economic crop. There are not many patents on the research and development of special organic-inorganic compound fertilizers and related application methods for the purpose of improving the soil for tobacco planting and improving the yield and quality of tobacco leaves

Embodiment 1

[0021] A special organic-inorganic compound fertilizer for flue-cured tobacco is characterized in that it comprises inorganic compound fertilizer and worm castings fermented by EM, and the weight ratio of inorganic compound fertilizer: the vermicompost fermented by EM is 7: 3; wherein: the inorganic compound fertilizer contains weight percent 10% N, 10% P by weight 2 o 5 , 25% by weight of K 2 O.

[0022] The EM-fermented vermicompost is a granulated feces discharged from the abdomen after the earthworms eat after spraying the EM stock solution after 25-30 days of fermentation in the process of stacking cow dung. The EM-fermented vermicompost contains 2.5% by weight of N, 1.27% by weight of P, and 0.8% by weight of K.

[0023] The EM used for cow dung fermentation contains effective active microorganisms such as lactic acid bacteria, saccharomyces, and photosynthetic bacteria. It is more mellow and sour or sour. EM is produced by Amuler Environmental Biotechnology (Nanjin...

Abstract

The invention belongs to the technical field of organic-inorganic compound fertilizers special for cured tobacco, and relates to an organic-inorganic compound fertilizer prepared specific to the special nutritional need and absorption rule of cured tobacco. The organic-inorganic compound fertilizer is prepared by fully and uniformly mixing an inorganic compound fertilizer (containing 10 percent of N, 10 percent of P2O5 and 25 percent of K2O) with EM (Effective Microorganism)-fermented earthworm cast (dairy manure) in the weight part ratio (3-7):(7-3). 100 kilograms of the organic-inorganic compound fertilizer are applied to every mou of tobacco field, and 70 kilograms of base fertilizer are applied to every mou of tobacoo field. The application method comprises the following steps of: performing hole application before transplanting of tobacco seedlings; performing top application by 30 kilograms / mou; and performing mixed application 25-28 days after transplanting. The organic-inorganic compound fertilizer has the advantages of persistent fertilizer effect, balanced nutrition and capabilities of improving the soil structure and water holding capacity of a tobacco field and enhancing the disease resistance of cured tobacco; the application method is consistent with the nutritional need and nutritional element absorption rule of cured tobacco; and by adopting the application method, the yield of cured tobacco can be increased, and the quality of tobacco leaves is improved.

Description

technical field [0001] The invention belongs to the technical field of special organic-inorganic compound fertilizer for tobacco. It uses biotechnology to ferment and utilize cow dung, mixes it with inorganic N, P, and K compound fertilizers in a certain proportion, and applies it scientifically in tobacco fields to achieve balanced fertilization, Improve the soil, inhibit flue-cured tobacco continuous cropping obstacles and improve the yield and quality of tobacco leaves. Background technique [0002] Fertilizer is the key to the production of high-quality tobacco leaves. The types of fertilizers and fertilization techniques directly affect the yield and quality of tobacco leaves and the soil nutrient status of tobacco fields. With the rise of my country's inorganic fertilizer industry in the 1980s, chemical fertilizers have become the main source of fertilizers for agricultural production, downplaying the important role of organic fertilizers in agricultural production, co...
