Fertilizing device for returning rice straw to field

Abstract

The invention discloses a fertilizing device for returning rice straw to field. The device comprises a rotary cultivator (1) which can be connected with a straw crushing agricultural machine; and twoends of the rotary cultivator (1) are respectively provided with support rods (2) which can be rotationally connected and matched with the rotary tiller, a straw guide box (3) which can be rotationally connected and matched with the support rod is arranged between the ends of the two support rods (2), a first ear seat (4) is welded and fixed on the rotary cultivator (1), a hydraulic rod (5) whichcan be rotationally connected and matched with the first ear seat (4) is arranged on the first ear seat (4), a second ear seat (6) which can be rotationally connected and matched with the hydraulic rod (5) is arranged at the piston shaft end of the hydraulic rod, and the second ear seat (6) is welded and fixed on the straw guide box (3). According to the present invention, the device has simple structure, the decay speed of rice straw can be effectively improved, and at the same time, the temporary barren phenomenon of the soil after a large amount of nitrogen fertilizer is consumed in the soil during the decay process can be overcome.

Description

technical field [0001] The invention relates to the technical field related to agricultural machinery, in particular to a fertilization device for returning rice straw to the field. Background technique [0002] Straw returning to the field is a measure of fertilizing soil fertility and increasing production that is generally valued in the world today. It can increase fertilizer and increase production while eliminating the air pollution caused by straw burning. Straw returning can increase soil organic matter, improve soil structure, loosen soil, increase porosity, reduce capacity, and promote microbial activity and crop root development. The main reason is that the existing straw returning method is to crush the straw In the future, it will be directly sprinkled on the ground, and the straw powder directly sprinkled on the ground often takes a long time to rot. In order to improve the utilization efficiency of the straw powder, the current common method is to crush the str...

Straw returning can increase soil organic matter, improve soil structure, loosen soil, increase porosity, reduce capacity, and promote microbial activity and crop root development. The main reason is that the existing straw returning method is to crush the straw In the future, it will be directly sprinkled on the ground, and the straw powder directly sprinkled on the ground often takes a long time to rot. In order to improve the utilization efficiency of the straw powder, the current common method is to crush the straw and sprinkle it on the soil surface, and then combine it with the plowing method. The machine mixes the straw powder into the soil. Although this method can effectively increase the decay rate of the straw and improve the structure of the soil layer, the straw powder will consume a lot of nitrogen in the process of decay in the soil layer. , and the lack of nitrogen in the soil will cause the root system of the crops to be underdeveloped, and the crops will grow poorly and even stiff seedlings will appear.
