Embodiment 1

[0025] The nutrient agent for planting tobacco leaves is obtained by the following preparation method:

[0026] ①Cleaning: Wash the discarded oyster shells with clean water to remove the silt and impurities on the surface of the oyster shells;

[0027] 2. drying: drying the oyster shells obtained in step 1, and pulverizing them with a ball mill to obtain 80 mesh oyster shell coarse powder;

[0028] ③Low temperature pulverization: The oyster shell coarse powder obtained in step ② is subjected to low temperature freezing at 0°C and low temperature sublimation drying in sequence, and then the liquid nitrogen is used as the grinding medium, and the ultra-low temperature pulverizer is used for low temperature pulverization at -80°C;

[0029] ④High-pressure micro-jet ultra-fine pulverization treatment, add the material obtained in step ③ to 5 times the weight of pure water and mix evenly, treat it with a high-speed shear emulsifier for 10 minutes, and then use high-pressure micro-je...

Embodiment 2

[0031] The nutrient agent for planting tobacco leaves is obtained by the following preparation method:

[0032] ①Cleaning: Wash the discarded oyster shells with clean water to remove the silt and impurities on the surface of the oyster shells;

[0033] 2. drying: drying the oyster shells obtained in step 1 and pulverizing them with a ball mill to obtain 100 mesh oyster shell coarse powder;

[0034] ③Low temperature pulverization: The coarse oyster shell powder obtained in step ② is subjected to low-temperature freezing at -10°C and low-temperature sublimation drying in sequence, and then liquid nitrogen is used as the grinding medium, and low-temperature pulverization is carried out at -100°C with an ultra-low temperature pulverizer;

[0035] ④High-pressure micro-jet ultra-fine pulverization treatment, add 6 times the weight of pure water to the material obtained in step ③ and mix evenly, treat it with a high-speed shear emulsifier for 5 minutes, and then use high-pressure mic...

Embodiment 3

[0037] The nutrient agent for planting tobacco leaves is obtained by the following preparation method:

[0038] ①Cleaning: Wash the discarded oyster shells with clean water to remove the silt and impurities on the surface of the oyster shells;

[0039] 2. drying: drying the oyster shells obtained in step 1 and pulverizing them with a ball mill to obtain 100 mesh oyster shell coarse powder;

[0040] ③Low temperature pulverization: The coarse oyster shell powder obtained in step ② is subjected to low-temperature freezing at -18°C and low-temperature sublimation drying in sequence, and then liquid nitrogen is used as the grinding medium, and low-temperature pulverization is carried out at -120°C with an ultra-low temperature pulverizer;

[0041] ④High-pressure micro-jet ultra-fine pulverization treatment, add the material obtained in step ③ to 5 times the weight of pure water and mix evenly, treat it with a high-speed shear emulsifier for 10 minutes, and then use high-pressure mi...

Abstract

The invention discloses a nutritional agent for tobacco planting. The nutritional agent for tobacco planting is prepared according to the following preparation method: (1) complete washing: completely washing waste oyster shells with clean water to remove silt and impurities from the surfaces of the oyster shells; (2) drying: drying and crushing the oyster shells obtained in the step (1) to obtain oyster shell coarse powder; (3) crushing at low temperature: performing low-temperature freezing and low-temperature sublimation drying on the oyster shell coarse powder obtained in the step (2) sequentially, and performing low-temperature crushing by an ultralow-temperature crushing machine at -80 to -120 DEG C and by taking liquid nitrogen as a grinding medium; (4) high-pressure microjet superfine pulverization treatment and drying to obtain the nutritional agent for tobacco planting. The nutritional agent for tobacco planting can remarkably increase each quality index of tobacco planting and can meet the planting requirements of high-quality tobaccos.

Description

technical field [0001] The invention relates to the technical field of tobacco planting, in particular to a nutrient for tobacco planting. Background technique [0002] my country is a big tobacco planting country. The tobacco leaves obtained from planting will be graded. According to the quality characteristics of different parts of the tobacco leaves, the color of the same part of the tobacco leaves after modulation reflects the internal quality. According to the maturity of the tobacco leaves, leaf structure, oil content, chroma, Graded by length. After grading, a large amount of low-grade tobacco leaves need to be processed and utilized urgently every year, otherwise it will cause environmental pollution and waste of resources. [0003] Chlorogenic acid is one of the most abundant and important polyphenolic compounds in tobacco. It is a phenylpropanoid compound produced by shikimic acid pathway in the process of plant body during aerobic respiration. It has antibacterial...
