Machine for returning corn straw to fields and applying bacteria

Abstract

The invention discloses a machine for returning corn straw to fields and applying bacteria, and relates to the technical field of agricultural machinery. The machine for returning corn straw to fieldsand applying bacteria comprises a transmission mechanism, a flail knife mechanism, a transporting device, a bacterium discharging device and a machine frame, wherein the machine frame comprises a left side plate, a right side plate, a bottom plate, a front cover plate, and a rear cover plate; two ends of the bottom plate are respectively connected with the lower ends of the left side plate and the right side plate; two ends of the rear cover plate are respectively connected with the rear sides of the upper ends of the left side plate and the right side plate; the front cover plate is mountedon the front side of the rear cover plate; the flail knife mechanism is arranged below the front cover plate; the transporting device is arranged below the rear cover plate; an external power source can drive the flail knife mechanism and the transporting device to move through the transmission mechanism; and the bacterium discharging device is arranged on the rear cover plate, a plurality of openslots are formed in the rear cover plate, and a plurality of discharge openings are formed in the rear end of the bottom plate. The machine for returning corn straw to fields and applying bacteria can realize sufficient combination of straw thoroughly-decomposed microbial inoculum and straw, so that the thorough decomposing speed of the straw is increased, the efficiency for returning straw to fields can be improved, and the cost of returning straw to fields is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a corn stalk returning field bacteria application machine. Background technique [0002] In recent years, the comprehensive utilization of crop straws is being widely promoted. However, due to the immature technology and the high cost of removing straws from the ground, one of the main ways to utilize straws is to return them directly to the field. In terms of soil fertility, returning corn stalks to the field can increase the content of organic matter in the soil, improve the microbial environment of the soil, and increase its activity. Improve soil fertility status. If it is combined with chemical fertilizers, it can significantly increase the content of trace elements such as C, N, K, and P in the soil, and improve the fertilizer retention capacity of the land. The direct return of corn stalks also plays an active role in moisture conservation and water conser...

AI Technical Summary

Problems solved by technology

However, the current bacteria-applying machinery in my country is to evenly spread the straw decomposing bacteria agent on the field surface. This method cannot fully integrate the straw decomposing bacteria agent with the straw, but instead makes the straw decomposing bacteria agent contact with the indigenous bacteria in the soil, and the straw decomposes. Bacteria and indigenous bacteria will have an antagonistic reaction due to competition for living space. Because the native bacteria are in a suitable living environment and have strong vitality, they will eventually partially or completely inactivate the bacteria in the straw decomposing bacterial agent and lose the ability to decompose straw. , affecting the decomposing effect of corn stalks
