Rice husk fermentation process of special fertilizer for tobacco

Abstract

The invention discloses a rice husk fermentation process of a special fertilizer for tobacco in the technical field of fertilizer fermentation, and the rice husk fermentation process comprises the following steps: 1, rice husks are placed in fermentation equipment, the fermentation equipment comprises a base and a supporting plate, and a plurality of water supplementing plates are arranged on the supporting plate; the water supplementing plate is composed of a plurality of flow guide pipes and a plurality of connecting pipes, and a plurality of overflow holes are formed in the upper surfaces of the connecting pipes and the flow guide pipes; the flow guide pipes communicate with a drainage pipe which is connected with a water pump, and the water pump is connected with a water storage tank; a temperature sensor and a humidity sensor are arranged on the supporting plate, and an oxygen generator is further arranged on the base; the rice husks are put into fermentation equipment; 2, urea and a microbial fermentation agent are put into a water storage tank, and are completely dissolved to obtain a mixed solution; 3, a water pump is started, and the mixed solution in the water storage tank is pumped by the water pump; and 4, during the rice husk fermentation period, oxygen is supplemented to the rice husks for 1-2 hours through an oxygen generator every 2-3 days. According to the scheme, balanced supplementation of a rice husk nitrogen source and water can be quickly realized.

Description

technical field [0001] The invention belongs to the technical field of fertilizer fermentation, and in particular relates to a fermenting process of special fertilizer chaff for tobacco. Background technique [0002] Rice husk, also known as rice husk, is one of the commonly used raw materials for tobacco special fertilizer. The chaff needs to be fermented before it can be mixed with other ingredients. Due to the rough texture and low nitrogen content of the chaff, when the chaff is fermented, it is necessary to add nitrogen source first, so that the carbon-nitrogen ratio in the chaff is 20-40, and then spray water on the chaff to make the water content reach 50%. ~70%; then add microbial starter to ferment the chaff. However, in the process of operation, it is difficult to mix the nitrogen source into the chaff, and because the moisture is difficult to penetrate into the chaff after accumulation, generally only 60-70 cm can be infiltrated. Therefore, it is necessary to tu...

Problems solved by technology

However, in the process of operation, it is difficult to mix the nitrogen source into the chaff, and because the moisture is difficult to penetrate into the chaff after accumulation, generally only 60-70 cm can be infiltrated, so the upper chaff needs to be turned over After that, the chaff below can be sprayed with water, which is extremely inefficient
