Problems solved by technology

Straw returning is the optimal way to utilize straw. At present, indirect returning and direct returning are mainly used. Among them, the direct returning mainly adopts crushing the straw and performing overturning or rotary burial. The production cost is increased, and the burial effect is not ideal, which affects follow-up work
[0003] Usually, straw returning to field is mostly local returning, that is, rice straw returning to paddy field, long-term implementation will affect the balance of soil organic matter composition

Embodiment 1

[0023] Embodiment 1: as Figure 1-Figure 3 As shown, the present invention is a farming method for returning the whole straw to the paddy field. The corn stalks 2 are spread on the surface of the paddy field 1 after rotary plowing. 2. The whole plant is pressed into the paddy field soil 1 to complete the operation of returning to the field.

[0024] The rake buried pressure roller device 3 includes a frame 35, a buried pressure roller assembly, a hydraulic cylinder and a hydraulic scraper 36. On the rod 351, the two connecting rods 353 are respectively connected with the hydraulic cylinder I33 and the hydraulic cylinder II34, and the other ends of the hydraulic cylinder I33 and the hydraulic cylinder II34 are connected to the vertical support rod 352 of the frame; The end of the frame 35 of the pressure roller assembly is connected to the hydraulic scraper 36 and the suspension frame 31 above the frame through a hydraulic cylinder III37, and the rotation angle of the hydrauli...

Embodiment 2

[0029] Example 2: The difference between this example and Example 1 is that the inclination angle α between the embedding rib 38 and the roller shaft 39 in this example is 5°, the amount of return to the field is controlled at 7500 kg per hectare, and the corn or rice straw The buried depth is 10cm.

[0030] Example 2: The difference between this example and Example 1 is that the inclination angle α between the buried pressure rib 38 and the roller shaft 39 in this example is 15°, and the amount of return to the field is controlled at 12000 kg per hectare, and corn or rice straw The buried depth is 15cm.

Abstract

The invention relates to a cultivation method for returning whole straw to a paddy field and a special harrowing and burying roller device, and belongs to the technical field of agricultural mechanical operation. The cultivation method comprises the steps that corn or rice straw is laid on the surface of the paddy field after rotary tillage, after water is added and soaks the field, the whole cornor rice straw is pressed into soil of the paddy field through the harrowing and burying roller device driven by a tractor, and the returning work is completed. The whole corn or rice straw is buriedto be returned to the paddy field, so that the straw smashing link is omitted; meanwhile, after the whole straw is buried, no residual straw floats on the ground surface, transplanting is facilitated,and the seedling survival time is shortened; the corn straw can improve the soil component of the paddy field, the soil porosity is increased, moisture preservation and fertilizer conservation are achieved, and the rice quality is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural mechanization operations, and in particular relates to a farming method for returning whole straws to paddy fields and a special harrowing ground-burying pressure roller device. Background technique [0002] Crop straw is an important biomass resource in crop production systems. According to incomplete estimates, about 620 million tons of corn stalks can be produced in my country every year. Reasonable use of straws and avoiding burning and polluting the environment have become a major problem at present. Straw returning is the optimal way to utilize straw. At present, indirect returning and direct returning are mainly used. Among them, the direct returning mainly adopts crushing the straw and performing overturning or rotary burial. The production cost is increased, and the burial effect is not ideal, which affects Follow up. [0003] Usually, straw returning is mostly local returning, tha...
