Description

A platform type tillage, seeding and fertilization operation device

technical field

The invention belongs to the technical field of agricultural machinery, and relates to a platform-type tillage, seeding and fertilization operation device, in particular to a compound operation platform device integrating subsoiling, deep rotary tillage, fertilization, sowing, furrow building and suppression.

Background technique

At present, the farming machinery in my country's rice and wheat planting areas has the problems of low duplex operation, high energy consumption, and high operating costs, which seriously restrict the sustainable development of rural planting. The existing farming system is divided into two types: farm and rural. The farm takes plowing and deep plowing as the main line, and carries out plowing→harrowing (2-3 times)→fertilization→sowing→ditching, five independent operations. , After plowing and deep plowing, the thickness of the plowing layer can be greatly increased. This technology has made great contributions to agricultural land cultivation, land protection, straw returning, maintaining soil organic matter, and fertilizing the plowing layer. The yield of land that adopts this technique is 10% to 30% higher than that of shallow tillage land. But the defects are also obvious, mainly manifested in the fact that the tractor needs to go down to the field four times for each tillage, and the level of compound operation is poor. The single-season operation cost is as high as 130-150 yuan/mu, resulting in high agricultural planting costs. In rural areas, rotary tillage is the main line, and the combined operations of rotary tillage → sowing → fertilization and ditching are carried out. The advantage of this farming process is that the degree of compound operation has been improved, and its single-season farming cost has been reduced to 70-90 yuan/mu . However, this process has the disadvantages of shallow rotary tillage depth and high straw ratio in the plowing layer, which seriously affects the growth of underripe crops. In addition, this process causes the cultivation layer to become shallow, which does not conform to the principles of land cultivation and soil fertilization, and is not conducive to the sustainable development of agriculture. Therefore, it is of great significance to invent a compound operation platform that can integrate subsoiling, deep rotary tillage, fertilization, sowing, furrow building, and suppression to realize integrated operations.
