手扶微耕机中耕、履带拖拉机中耕均能改善土壤的理化性质，具体表现在耕作后土壤相对含水量均较对照

的推移，耕作后土壤容重、硬度值会不同程度地逐渐上升，土壤孔隙度则会不同程度地逐渐下降；而不同耕

工耕作的10 倍而成本只是人工耕作的0.39 倍。表明采用手扶微耕机或履带式拖拉机对桂林毛尖茶园进行
机械耕作作业均是可行的，同时为机械耕作在改良土壤理化性质上提供了理论依据，也有利于桂林毛尖茶

| In order to further optimize the cultivation and agronomy technology of Guilin Maojian tea garden，
Through the modification of the experimental site，contrast no farming，the effect，efficiency and cost of different
tillage methods were studied in this paper. The results showed that：human farming，micro tillage machine，crawler
tractor can improve the physical and chemical properties of soil. After farming the soil had good water retention but
low moisture content compared to the contrast group，while the soil bulk density and hardness value were significantly
lower than the contrast，and the porosity of soil was significantly higher than that of contrast. With the passage of
time after farming，soil bulk density and hardness value will gradually increase，ant the porosity of soil decreases
gradually. There were significant differences between the effect，efficiency and cost of different farming methods. The
crawler tractor is the best and most stable. At the same time，the operating efficiency was 10 times of human farming while the cost 0.39 times of human farming. But for tea plantations that are intended to be mechanized，In addition to
the mechanical and technical personnel to be configured in place，the site conditions，planting mode and mechanical
way reservation of tea garden should be planned accordingly. It is recommended to select flat or gentle slope for
reclamation，preferential selection of non-sexual tea tree varieties，with over 180 cm long distance planting and
the main road construction more than 3.0 m，trunk road 2.0 m above，and the tea garden and surrounding mountain
forests，farmland should be equipped with isolation ditch and drain. This study shows that it is feasible to use the
micro tillage machine or crawler tractor to carry out the mechanical tillage work of the Guilin Maojian tea garden，
it provides a theoretical basis for mechanical cultivation to improve the physical and chemical properties of soil. It is
also conducive to the acceleration of the mechanization of the Guilin Maojian tea garden. |
