Description

Technical Field

[0001] The utility model relates to the field of grassland improvement, in particular to a deep loosening and pipe-burying reseeding machine for sloping grassland. Background Art

[0002] Studies have shown that drought is a major bottleneck restricting the improvement of grasslands and the development of grass industry. In particular, grasslands have been used more and managed less for a long time, and the underground grass roots are misconnected and the soil is compacted. Not only is natural precipitation easy to form runoff and difficult to infiltrate, but also underground water is easy to evaporate to the ground through capillary action. Due to surface runoff, almost all rainfall on slopes flows downhill. The underground water content on the slopes and in the middle of the slopes is very low, which is difficult to provide the water needed for plant growth. In addition, due to surface runoff, nutrients such as soil organic carbon are easily lost. Studies have found that the soil organic carbon pool is one of the most important carbon pools in terrestrial ecosystems, and it has a positive effect on reducing the concentration of greenhouse gases in the atmosphere and mitigating climate warming. Grassland ecosystems play an important role in the terrestrial carbon cycle. Improving grassland soil organic carbon can not only effectively slow down the increase in atmospheric CO2 concentration, but also has important significance for protecting grassland ecological security. Therefore, for grassland slopes, the content and distribution characteristics of soil organic carbon in the soil layer structure are an important indicator for measuring soil quality and soil health, and are direct factors affecting soil fertility and forage yield. According to statistics, for slopes with a slope greater than 8°, terraces are not only an important measure to control soil erosion, but also greatly reduce the loss of soil organic carbon, and are one of the important ways to improve the carbon sequestration capacity of terrestrial ecosystems. However, for the vast grasslands in pastoral areas, where the land is vast and the population is sparse, due to limited labor, it is impossible to implement the terrace planting model, and the contour planting model must be adopted. The production practice in recent years has proved that this model is feasible and has significant effects. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a deep loosening and buried pipe reseeding machine for sloping grassland. The reseeding machine cuts the roots of the turf without destroying or less destroying the original vegetation of the grassland to improve the soil ventilation condition, and can timely reseed pasture and fertilize, improve soil permeability and soil fertility, and thus realize the grassland production capacity.

In order to improve the soil penetration performance of the multi-purpose deep loosening plow, adapt to the root cutting of grasses of different soil types with heavy grass root packing, and enhance the air permeability of the soil, the front end of the plow post is processed with a blade angle of 25°~30°. In order to enhance the sliding and soil penetration ability of the front end of the plow post and increase the strength of the plow post, the plow shovel has a soil penetration angle of 10°~15°, and the front end of the plow post is processed into a curved shape with an arc radius of 235mm~250mm.

In order to reduce soil resistance, they are wedge-shaped, narrow in front and wide in the back, and a fertilizer chamber is formed in the middle, and a fertilizer delivery pipe is welded on the upper end. A drip irrigation pipe guide pipe is provided behind the plowboard side plate, which is used to bury the drip irrigation pipe for guidance and laying. In order to reduce the friction between the plow bottom and the soil at the bottom of the ditch, ensure that the ditch wall and the bottom are flat and tidy, and reduce the collapse of the ditch wall, the angle between the lower edge of the plowboard side plate and the ground is set to 5°~8°.

It can complete the processes of turf slicing, cutting grass roots, loosening soil, adding fertilizer, reseeding forage, deep burying drip irrigation pipes, and pressing turf at the same time. The loosening depth can reach 200-250mm, which greatly improves the air permeability and water permeability of the soil, regulates natural factors such as water, air, heat and vegetation in the grassland ecological environment, and improves the utilization rate of nutrients by plants. 2. The turf is scratched with this reseeding machine, which has little disturbance to the soil. The plowshare can easily break the plow bottom layer and form an inverted T-shaped groove underground, which enhances the speed and amount of rainwater infiltration, plays a role in moisture conservation, and helps to make the excellent forage grass of rhizome type and rhizome-sparse clump type reproduce in large quantities and grow vigorously, which is conducive to natural sowing and artificial sowing, and accelerates the natural renewal and rejuvenation of grassland. 3. This reseeding machine opens a gap of only 30-40mm in the grassland without turning over the turf or damaging the grassland. 4. When the plow column is installed, the angle between the upper edge of the plow blade and the horizontal line is 10°~15°, so that the plow blade is facing downward, which improves the performance of the plow blade entering the soil and reduces the traction resistance. 5. It has a wide range of uses and can be used for flat grassland operations as well as for contour deep loosening operations on grasslands with an altitude of less than 8°, meeting the agronomic requirements of improving sloping grasslands and preventing soil water and nutrient loss.
