Description

Wheat rotary cultivator

technical field

The utility model relates to wheat sowing equipment, in particular to a wheat rotary tillage machine.

Background technique

Soil preparation before sowing is a basic link in agricultural production. Wheat is the main food crop in my country and has a wide planting area. Improving the technology of wheat sowing and soil preparation is a major strategic issue related to the national economy and people's livelihood, social stability and economic development. Increasing wheat grain production and ensuring sufficient grain sources are the prerequisites for ensuring people's livelihood and stability.

However, the existing rotary tillage soil preparation machines cannot be adjusted according to the local land conditions, because the soil is cultivated all the year round, so that a relatively hard plow bottom layer is formed under the plow layer, which seriously affects the development and rooting of the crop root system, greatly reducing the absorption of nutrients by the root system. The scope of the soil; the performance of soil water and fertilizer retention is reduced, and the ability to resist drought and waterlogging is reduced. According to the survey, long-term rotary tillage increases soil water loss by 20%, fertilizer utilization rate is only about 30%, and wheat yield per mu is reduced by 80 catties. If there is no deep plowing for a long time, the soil's potential for increasing production cannot be fully tapped, because the depth of subsoiling should be determined according to local conditions, not only according to the local soil quality, plow layer, weather during plowing, and planting crops, but also consider labor and agricultural machinery. conditions of furniture and fertilizers.

In the past, the traditional rotary plow could only crush the soil in the front and rear directions. Such crushing effect is not good, and the function is single, which may easily cause problems such as too much straw in the seed bed and poor crushing of the seed bed. It is difficult to break the stubble, and the larger straw and weeds will also block the seeding pipes and fertilizer pipes of the planter.

Moreover, too much straw in the seed bed will cause the wheat seeds to be sown on the straw to fail to germinate. The straw absorbs a lot of water in the seed bed, coupled with ventilation, the seed bed is prone to drought. Poorly broken soil in the seed bed will lead to larger soil clods in the seed bed, which is ventilated, easy to press the seedlings, and affects the emergence rate and tillering rate.
