不同耕作方式对茶园土壤理化性质和养分的影响

以不耕作为对照，研究了不同耕作方式对茶园土壤理化性质和养分含量的影响。结果表明：中耕、手扶深耕、拖拉机深耕2—4个月后土壤相对含水量和土壤容重较对照低，但茶园的根系干重以及20～40cm土层的碱解氮、速效磷、速效钾含量均有所增加。说明合理耕作有利于茶树根系生长和茶园土壤养分的均衡；使用耕作机对茶园进行深耕、中耕均是可行的。...

Summary:以不耕作为对照，研究了不同耕作方式对茶园土壤理化性质和养分含量的影响。结果表明：中耕、手扶深耕、拖拉机深耕2—4个月后土壤相对含水量和土壤容重较对照低，但茶园的根系干重以及20～40cm土层的碱解氮、速效磷、速效钾含量均有所增加。说明合理耕作有利于茶树根系生长和茶园土壤养分的均衡；使用耕作机对茶园进行深耕、中耕均是可行的。

Taking no tillage as the check, we studied the effects of different tillage methods on the physical, chemical prop- erties and nutrient of soil in tea plantation. The results indicated that： during 2 ~ 4 months after tea plantation was tilled by differ- ent methods （ intertillage, deep ploughing by hand, or deep ploughing by tractor） , in comparison with the check, the soil relative water content and bulk density were decreased, while the tea mot dry weight, and contents of available nitrogen, available phos- phorus and available potassium in 20 ~ 40-cm soil layer of tea plantation were increased. The above results suggest that reasonable
