Embodiment 1

[0012] (1) In Zunyi City, Guizhou Province, fresh horse manure was collected, and wheat straw and discarded tobacco leaves (stalks) were crushed to 3-5 mm. Mix water, wheat straw, waste tobacco leaves (stalks), fresh horse manure, and urea according to the mass ratio of 40:50:50:1.5:1, and stack them into strips with a width of 1.4m, a height of 1.1m, and a length of 5m. shape, covered with plastic film. On the 5th, 9th, 13th, 17th, and 21st days of stacking, the stacks were turned once each, and the stacking was performed for 21 days to produce a fermentation agent.

[0013] (2) Choose a flat corner of the field, stack the wheat straw parallel to the ground to a thickness of 20cm, step on it tightly, and sprinkle 500g of fermentation agent, urea and magnesium sulfate for each 100kg of wheat straw, and then stack the waste tobacco leaves in the field ( Stem) 40cm thick, trampled tightly, every 100kg of waste tobacco leaves (stem) mixed with 250g of fermentation agent, urea an...

Embodiment 2

[0015] (1) In Puge County, Liangshanzhou, Sichuan Province, fresh horse manure was collected, and wheat straw and discarded tobacco leaves (stalks) were crushed to a thickness of 3-5 mm. Take water, wheat straw, waste tobacco leaves (stalks), fresh horse manure, and urea, mix them evenly according to the mass ratio of 40:50:50:1.5:1, and stack them into a long strip with a width of 1.6m, a height of 1.4m, and a length of 5m , covered with plastic film. On the 5th, 9th, 13th, 17th, and 21st days of stacking, the stacks are turned once each, and after 24 days of stacking, the fermentation bacteria are produced.

[0016] (2) Choose a flat corner of the field, stack the wheat straw parallel to the ground to a thickness of 30 cm, step on it tightly, and mix 500 g of fermentation agent, urea and magnesium sulfate for every 100 kg of wheat straw, and then stack the waste tobacco leaves in the field The (stem) is 60cm thick, and it is stepped on tightly. Every 100kg of waste tobacco ...

Abstract

The invention relates to a method for producing an organic fertilizer by processing waste tobacco leaves in the field, which comprises the following steps: firstly, preparing a fermentation bacterial agent by utilizing fresh horse manure, wheat straws, the waste tobacco leaves and the like; and performing compost treatment on the waste tobacco leaves by utilizing the fermentation bacterial agent to produce the organic fertilizer. According to the invention, time of processing the fresh waste tobacco leaves in the field is short; processing on the fresh waste tobacco leaves in the field can be completed in 60 to 90 days; stink and waste liquid which are generated due to natural rot of the fresh waste tobacco leaves in the field can be avoided; and in the treatment process, the high temperature period in which the temperature of materials is higher than 60 DEG C is over 30 days, pathogenic microorganisms can be effectively killed and mycosis transmission generated caused by the fact that the wheat straws and the tobacco leaves are directly returned to the field is prevented. The method is implemented on site, simple to operate, labor-saving and low in cost and has strong practicality.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a method for processing waste tobacco leaves in the field to produce organic fertilizers. Background technique [0002] Southwest China is one of the main production areas of flue-cured tobacco in my country. The planting area and output of flue-cured tobacco in Yunnan, Guizhou, Sichuan and Chongqing exceed 70% of the country's total. During the cultivation process of flue-cured tobacco, technical measures such as topping, bud stroking, and removal of lower and upper tobacco leaves generate a large amount of waste, which is left in the field or in waste tobacco leaf collection pools. Its natural decay produces stench and waste water, pollutes air and water, spreads diseases, and wastes a lot of organic matter and nutrient resources. Due to the lack of labor force in rural areas and the difficulty of transportation in mountainous areas, it is difficult to centralize and harml...
