Method for preparing organic fertilizer special for banana fruit trees by using fresh tobacco plant waste

Abstract

The invention relates to a method for preparing an organic fertilizer special for banana fruit trees by using fresh tobacco plant waste of flue-cured tobacco fields. The method comprises the following steps of: (1) collecting and cutting the tobacco plant waste, spraying bacillus licheniformis liquid for fermentation, stacking, filming for heat preservation, turning stacks and air-drying to obtain a fresh tobacco plant waste solid product and a liquid product after preliminary solid fermentation; and (2) uniformly mixing the fresh tobacco plant waste solid product after fermentation and dry chicken manure according to a weight ratio of 35-40:65-60, spraying a zymocyte agent which mainly contains lactobacillus, yeast and photosynthetic bacteria, uniformly stirring and filling in a sealed bag to perform sealed natural fermentation so as to obtain an organic fertilizer product after secondary fermentation. The method has the advantages of low pollution, clean tobacco fields, less tobacco plant diseases, low cost of the organic fertilizer, obvious increase in production of banana, capabilities of improving soil structure, improving land fertility and facilitating heavy metal degradation in plants, improved cold resistance, drought resistance, lodging resistance and resistance to disease and insect of banana plants and high fruit quality.

Description

Technical field [0001] The present invention relates to a method for the disposal of fresh tobacco plant waste, in particular to a method of using fresh tobacco plant waste as the main raw material for processing banana fruit tree special organic fertilizer. Background technique [0002] The tobacco industry in China produces a large number of discarded fresh tobacco plant wastes (including uncollected flue-cured tobacco leaves, damaged tobacco leaves, fireworks, tobacco twigs) in the production of tobacco leaves and optimization of tobacco leaf structure. The tobacco plant wastes are organic materials with high potassium and high protein content. , The conventional treatment method is to concentrate on-situ decay, bury and discard the tobacco fields in other places, which brings about waste of resources and environmental pollution. Banana fruit trees are produced in tropical and subtropical regions. These areas have fast soil nutrient conversion, poor soil and lack of organic ma...

Problems solved by technology

Most of the existing banana-specific fertilizers are inorganic fertilizers (such as 01128696.2, 201120068726.0, etc. disclosed in Chinese patent documents). This type of fertilizer can indeed increase the yield of bananas at the beginning of application, but it will destroy the soil structure and reduce land fertility over time. , is not conducive to the degradation of heavy metals in the plant, and eventually the cold resistance, drought resistance, lodging resistance, and disease and insect pest resistance of banana plants decline year by year

[0003] Although there are many organic fertilizers on the market, these organic fertilizers are not specially designed for the growth characteristics of bananas. Although they can increase the yield of bananas to a certain extent, the effect is very limited; what is more important is the potassium nutrient in these organic fertilizers Most of them are added inorganic potassium fertilizers, and the cost is very high
