Organic functional bacterial fertilizer containing tobacco waste and capable of regulating pH value of alkaline soil and preparation method thereof

Abstract

The invention relates to agricultural fertilizer. Organic functional bacterial fertilizer containing tobacco waste and capable of regulating pH value of alkaline soil includes the following components: 5-60 wt% of tobacco waste, 10-50 wt% of livestock and poultry feces, 10-20 wt% of a pH regulator, 5-15 wt% of humic acid and 0.2-3 wt% of biological bacterial agent. The preparation method of the organic functional fertilizer is as below: crushing the tobacco waste into a powder, and adjusting carbon to nitrogen ratio to 25:1; fermenting livestock and poultry manure under the condition of 60-80 DEG C for 7 days; crushing the pH regulator into a powder; uniformly mixing the three and conducting stacking fermentation; and drying and screening the fermentation materials and adding humic acid and biological bacterial agent to produce the organic functional fertilizer. The invention has the effects of regulating pH value of alkaline soil and alleviating the toxicity of heavy metals to crops.

Description

technical field [0001] The invention relates to agricultural fertilizers, in particular to a functional biological bacterial fertilizer and a preparation method thereof. Background technique [0002] Soil pH is one of the important indicators of soil quality and has a great influence on soil fertility and plant growth. The overall change law of soil pH in my country is from strong acidity and acidity in the south to weak acidity in the Jianghuai region, and then transitions to neutral and alkaline in the north. In the arid and semi-arid areas of northern China and coastal areas, due to strong evaporation and salt-rich groundwater rising through capillaries and accumulating on the surface, coupled with improper irrigation, drainage and agricultural technical measures, the salt in the soil plow layer accumulates, eventually Raise soil pH and salinize soil. Moreover, soil salinization will deteriorate the soil structure, seriously compact the soil, seriously affect the growth...

AI Technical Summary

Problems solved by technology

[0005] In the above-mentioned technical scheme, the fertilizer or additive for adjusting the soil pH value is composed of inorganic substances or some synthetic organic macromolecular materials, and its nutrients, the conservation of nutrients, and the improvement of soil structure are all insufficient, and its raw materials may be Contains heavy metals or toxic ingredients, and has a single function. For this reason, there is an urgent need for a functional fertilizer that can specifically adjust the pH value of the soil, has nutrients, avoids pests, prevents diseases, and can be used in organic production.
