摘要
通过田间试验研究不同机械耕作方式对茶园土壤物理性状的影响。设置免耕（MG）、高地隙多功能茶园管理机械卧式旋耕（WX）、立式旋耕（LX）、深松铲耕（SS）和小型茶园翻耕机翻耕（FG）5种耕作方式,分析其对茶园0~45 cm土壤紧实度、容重和固、液、气三相比的影响。结果表明,与免耕对土壤物理性状的影响相比,深松铲耕处理对0~30 cm土壤紧实度的降低作用最好,卧式旋耕处理对30~45 cm土壤紧实度的降低作用最好;卧式旋耕、立式旋耕处理对0~15 cm土层土壤容重、孔隙度、三相比的改善作用最好,翻耕处理对15~30 cm土层土壤容重、孔隙度、三相比的改善作用最好。可见,高地隙多功能茶园管理机械的最佳耕作方式为卧式旋耕,在不适宜大型机械作业的茶园,选用小型茶园翻耕机亦可达到较好的耕作效果。
In order to study the influence of different tillage modes on physical properties of tea garden soil, five different tillage modes were adopted in a field experiment. They were no-till （MG）, horizontal rotary tillage （WX） by the high-clearance self-propelled multi-function tea farm manager （HSM）, vertical rotary tillage by HSM （LX）, subsoiling by HSM （SS）, and plowing by a mini-type cultivation management machine （FG）. Effects of dif- ferent tillage modes on soil compactness, soil bulk density and three-phase ratio of soil in the 0-45 cm soil layers in tea garden were analyzed after the 27-day experiment. The results showed that compared with the effect of MG on soil physical properties, SS and WX had the best effect on reducing the soil compactness in 0-30 and 30-45 cm soil layer, respectively. WX and LX showed the best result on improving soil bulk density, porosity, and three-phase ratio in 0-15 cm soil layer. While FG showed the best on improving soil bulk density, porosity, and three,phase ratio in 15-30 cm soil layer. Therefore, the best tillage mode for high-clearance self-propelled multi-function tea farm management is horizontal rotary tillage. In tea gardens where the large-scale machinery is not applicable, the mini-type cultivation management machine is a better choice and can bring, a desirable effect.
