Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a soil trough test bench for a giant fungus grass soil contact device experiment. Background Art

[0002] Giant Juncao was introduced to my country by Lin Zhanhui in 1983. After years of research, its application has been expanded to edible fungus culture medium, soil and water conservation, sand control, livestock and poultry forage, and development of biomass new energy, forming an internationally leading comprehensive technology of Juncao with independent intellectual property rights, effectively solving the world problem of "contradiction between fungi and forests". The promotion value of giant Juncao has been expanding year by year, which requires large-scale planting. Juncao planting is the most labor-intensive and cumbersome link. It includes ditching, fertilization, seeding, covering soil and other processes, which are labor-intensive processes. However, at present, my country's Juncao planting machinery has problems such as poor adaptability, low mechanization degree and production efficiency, and cannot adapt to the operating environment of wasteland and slopes in Fujian's hilly landforms. In order to further improve the adaptability of Juncao planting equipment, reduce the labor intensity of manual planting, and accelerate the mechanization process of the whole process of Juncao production, giant Juncao planting machinery and equipment for the agronomic requirements of planting in Fujian have been developed. As a key component of planting machinery, the soil contact device can perform corresponding trenching, soil covering and compaction processes in the field according to the agronomic requirements of different crops. The working performance of the soil contact device is related to the distribution of seeds in the seed furrow and the germination rate of seedlings, as well as the balance, stability and energy consumption of the whole machine.
