Tobacco stem field stacking and retting fermentation method and product

Abstract

The invention provides a tobacco stem field stacking and retting fermentation method. After tobaccos are matured and harvested, tobacco stems are collected on the spot and are broken according to a certain size; and then stacking and retting fermentation is performed on the tobacco stems by mixing the tobacco stems with water, soil, cow dung, phosphatic fertilizer, a ferment activator and lime according to proper proportions. The invention also provides a compost product produced by the tobacco stem field stacking and retting fermentation method. A using method for the compost product obtained by tobacco stem stacking and retting fermentation is characterized in that the compost product is fertilized every two crop planting periods preferably; the fermented compost product is used as a base fertilizer; and a ditch is formed, and the compost product is fertilized into the deep ditch. According to the tobacco stem field stacking and retting fermentation method, the application amount of chemical fertilizers can be reduced, a soil ecological environment is protected, the soil is improved, the soil fertility is improved, and the tobacco stem field stacking and retting fermentation method is safe and ecological. By the method, raw materials are readily available, convenient to collect, easy to operate, environmentally-friendly, sanitary and low in cost, and tobacco farmers can easily master the method; the cost is low, the expense is low, the production technology is simple ad can be easily popularized and applied in a large tobacco area; the quality of a product is stable; and the economical and ecological benefits are outstanding.

Description

technical field [0001] The invention relates to the field of agricultural biological composting, in particular to a field composting and fermentation method and product of tobacco stalks. Background technique [0002] China is a big country in growing and planting tobacco leaves. In 2012, the planting area was 21.18 million mu. Based on the tobacco stalk yield of about 130 kg per mu, the country can obtain more than 2.7 million tons of tobacco stalk. According to research and analysis, the weight of xylem in tobacco stalk accounts for more than 75% of its total weight, phloem accounts for about 15%, and pith accounts for less than 10%. Tobacco stalk contains a large amount of cellulose and lignin, carbon, nitrogen, phosphorus, potassium, The content of calcium, magnesium, and other trace elements is also very rich. In a tobacco stalk, the nitrogen content accounts for about 1.1% of its weight, phosphorus is about 0.32%, and potassium oxide is about 1.85%. [0003] With the ...
