Abstract
Description
Technical Field
[0001] The utility model relates to the field of grassland improvement, in particular to a natural grassland high-pressure water flow tearing turf reseeding machine. Background Art
[0002] The causes of grassland degradation can be explained from two aspects, namely natural factors and human factors, and natural factors are particularly important. Through years of research, the basic reason affecting forage yield is due to the dry climate and the lack of soil water that can be used for plant growth. Livestock graze and trample all year round, causing the land to become compacted, blocking air from entering the soil layer. In addition, natural grasslands have not been improved and utilized for many years, and the roots of the grasslands are tangled, which is not conducive to the activity of aerobic soil microorganisms, and most of the oxides leached from the surface are reduced to suboxides, which cannot be absorbed by plants. Scientific research has shown that cutting the roots and loosening the soil of grassland can break up and loosen the soil, increase the contact surface with the air, allow oxygen to enter the soil, and create favorable conditions for the activity of aerobic microorganisms. In the second year of improvement, a dense grass layer is formed on the aboveground part, and the yield is generally increased by 30-50%, or even more than doubled. It can be seen that promoting the improvement process of cutting the turf and not plowing the soil is the most effective means to improve grasslands on a large scale.
[0003] Over the years, researchers have developed wallless plows, disc cutters, deep loosening plows and other machines. However, given the harsh and fragile grassland environment, grassland improvement has always been a difficult problem for improvement departments and scientific research departments to solve. If you are not careful, all your efforts will be wasted. There are still certain defects, which do not meet the agronomic requirements of improving natural grasslands. For example, after loosening the soil, it is easy to turn over the turf soil and destroy the grassland structure. If water is not diverted for irrigation in time, it is easy to cause desertification. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a natural grassland high-pressure water turf-breaking and reseeding machine, which can cut the roots of the turf without destroying or less destroying the original vegetation of the grassland, so as to improve the soil ventilation condition, and can timely reseed pasture and fertilize, thereby improving soil permeability and soil fertility.
[0005] The technical problem to be solved by the utility model is achieved by the following structure: a natural grassland high-pressure water turf scratching and reseeding machine, the structure includes a water tank, a main frame, a suspension frame, a grass seed box, a main gearbox, a support frame, a walking wheel, a high-pressure water nozzle, and a sliding palm.
