Problems solved by technology

Due to the climatic characteristics of Enshi tobacco area, drought often occurs after transplanting tobacco seedlings. In the case of insufficient precipitation, fertilizer nutrients cannot be released quickly, resulting in early growth and rapid growth of tobacco plants. Therefore, a special compound fertilizer for tobacco with fast fertilizer nutrient release rate was developed. is the primary way to solve the above problems
In recent years, with the large-scale application of chemical fertilizers, the physical and chemical properties of the soil in Enshi Tobacco Area have undergone major changes. The original formula of tobacco-specific fertilizers can no longer meet the needs of the production of characteristic high-quality tobacco leaves. It is necessary to develop more effective fertilizers according to the current soil conditions. Fertilizer formula

Embodiment 1

[0011] The following components by weight: 37.4 parts of potassium sulfate, 11.5 parts of potassium nitrate, 4 parts of potassium chloride, 13.7 parts of ammonium nitrate phosphorus, 28.3 parts of monoammonium phosphate, 2 parts of borax, 3 parts of Guanyin soil, mixed evenly and put into The feeding port of the granulation production line is granulated by the roller granulation method, and at the same time according to the original formula (36.3 parts of potassium sulfate, 11.5 parts of potassium nitrate, 11.1 parts of ammonium nitrate, 26.3 parts of monoammonium phosphate, 14.8 parts of Guanyin clay) The ratio of fertilizer feeding is also granulated, as a comparison.

[0012] Take two watch glasses of the same size, place them on the test bench, add 10 mL of water each, put in 20 grains of the tobacco-specific compound fertilizer of the present invention and the original formula compound fertilizer, and observe its disintegration rate in the aqueous solution After 5 minutes...

Embodiment 2

[0014] Carry out granulation of tobacco-specific compound fertilizer of the present invention and former formula compound fertilizer by formula described in embodiment 1 respectively, and measure the compressive strength of compound fertilizer after granulation, the compressive strength of tobacco-specific compound fertilizer of the present invention The compressive strength of the original formula compound fertilizer was 26.2 N, and the compressive strength did not change much. Storage, transportation and application showed that the compressive strength of the tobacco-specific compound fertilizer of the present invention fully meets the requirements.

Embodiment 3

[0016] Use the tobacco-specific compound fertilizer and the original formula compound fertilizer of the present invention for tobacco leaf field production, plant Yunyan 87 variety tobacco leaves in fields with uniform fertility, and apply the tobacco-specific compound fertilizer and the original formula compound fertilizer according to the invention respectively , the method of fertilization is consistent with the total nutrients of the fertilizer, and the field management measures and curing measures are also consistent. Record the yield and quality of tobacco leaves after curing and the ratio of middle and high-grade tobacco, see Table 1. It can be seen from Table 1 that the application of the tobacco-specific compound fertilizer of the present invention can significantly improve the yield and quality of tobacco leaves and the rate of middle and high-grade tobacco. The output (199.76kg / mu) of the tobacco special fertilizer of the present invention is 6.47% higher than the or...

Abstract

The invention relates to a special tobacco composite fertilizer applicable to a specific mountain area. The special tobacco composite fertilizer is characterized in that the ratio of nitrogen, phosphorus and potassium in the fertilizer is determined according to demands of quality and style characteristics of tobacco leaves and detection results of soil in a tobacco-growing area in Enshi, Hubei Province, China; and trace elements that the tobacco-growing area in Enshi lacks are supplemented. Compared with a traditional formula, the special tobacco composite fertilizer provided by the invention reduces the proportion of white clay and has an increased disintegration rate by increasing the total content of nutrients; and after application of the special tobacco composite fertilizer, a nutrient release curve is more consistent with the nutrient demand curve of tobacco plants. The improved special tobacco composite fertilizer is applied to a specific mountain area and substantially output and quality of tobacco leaves.

Description

technical field [0001] The invention relates to the field of tobacco agriculture, relates to a tobacco fertilizer suitable for specific mountainous areas, in particular to a special compound fertilizer for tobacco in mountainous areas. Background technique [0002] Tobacco-specific compound fertilizer is a fertilizer researched and developed according to the nutritional characteristics and requirements of tobacco, which can meet the basic nutritional requirements for the growth and development of flue-cured tobacco. At present, tobacco-specific fertilizers have achieved zonal formulations, taking into account the characteristics of tobacco growth and development in various regions and the basic status of soil fertility, and can meet the needs of tobacco in different ecological regions for nutrient forms, types and quantities, and meet the needs of tobacco in different growth stages. Fertilizer application technical requirements. [0003] Enshi is the main tobacco producti...
