Embodiment Construction

[0024] use as Figure 1-Figure 5 A method for crushing straw and returning it to the field according to an embodiment of the present invention is described as follows.

[0025] Such as Figure 1-Figure 3 As shown, a method for crushing and returning stalks to the field according to the present invention comprises the following steps:

[0026] S1: The storage tank is fixed on the inner top plate of the discharge end of the covering cover in the straw crushing and returning equipment. The storage tank is used to place nitrogen fertilizer. The bottom of the storage tank is equipped with a spraying port for spraying. Nitrogen fertilizer, and mixed with the straw conveyed on the first conveyor belt; use the power of the first conveyor belt to scatter the straw, and mix it with the nitrogen fertilizer scattered inside the storage tank, which can improve the uniformity of nitrogen fertilizer and straw mixing, It is beneficial to adjust the carbon-nitrogen ratio, which is beneficial...

Abstract

The invention belongs to the technical field of straw smashing and returning and particularly provides a straw smashing and returning method. The method comprises the following steps that a storage tank is fixedly connected to an inner top plate in the discharging end of a cover in a straw smashing and returning device and used for storing a nitrogen fertilizer, the bottom of the storage tank is provided with a spraying-scattering port, the spraying-scattering port is used for scattering the nitrogen fertilizer, the nitrogen fertilizer is mixed with straw conveyed out of a first conveying belt, the straw mixed with the nitrogen fertilizer naturally falls, the bottom of the cover is provided with a vibration screen, the straw mixed with the nitrogen fertilizer falls to the vibration screenand is screened, two sides of the vibration screen are provided with air bags, a composite biological microbial agent is arranged in the air bags, the tops of the air bags are provided with outlets, the top ends of the outlets are opened and inward, the outlets are used for spraying out the composite biological microbial agent, the straw sprayed with the composite biological microbial agent waitsfor decomposition in fields, and accordingly straw returning is achieved.

Description

technical field [0001] The invention belongs to the technical field of straw crushing and returning to the field, in particular to a method for crushing and returning straw to the field. Background technique [0002] Straw is the general term for the stems and leaves of mature crops. It usually refers to the remaining parts of wheat, rice, corn, potato, rape, cotton, sugarcane and other crops after harvesting seeds. More than half of the photosynthetic products of crops exist in straw. Straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter. It is a multi-purpose renewable biological resource. However, when the existing straw is crushed and returned to the field, when nitrogen fertilizer is applied, the nitrogen fertilizer is mixed with the straw. Inhomogeneous, which affects the effectiveness of nitrogen fertilizer and is not conducive to the growth of crops. At the same time, the straw cannot be spread evenly in the field after crushing, res...
