Description

A local rotary tillage sowing fertilization straw mulching machine

technical field

The invention relates to a partial rotary tillage, sowing, fertilizing, straw covering and returning machine, which belongs to the technical field of agricultural machinery.

Background technique

Most of the wheat is planted after the rice is harvested. The rice stubble has problems such as high moisture content, soil compaction, and a large amount of rice straw. This brings great difficulties to mechanical sowing of wheat. First, it is difficult for the power machine to go to the field. Sowing is difficult, and the third is that it is difficult to handle a large amount of rice straw, especially after encountering rainy days during the sowing period, mechanical sowing is more difficult, and the planting time has to be postponed, which delays the farming time and directly affects the growth and yield of wheat.

At present, there is no no-tillage machine suitable for the high moisture content of rice stubble in my country. The current way of planting wheat in rice stubble land in China is:

Using the straw returning machine to crush the straw, the rotary cultivator to crush the soil and prepare the soil, and the sowing and fertilizing machine to operate, three operating procedures are required. The operating costs of the three operating procedures are high, the number of times the tractor compacts the ground, and the soil is easy to harden, which is not conducive to the growth of crops. Directly affect crop planting and benefits.

Especially in the rainy weather during the wheat planting period, the soil moisture content is too high, and this mode of operation cannot plant wheat.
