茶园耕作对土壤理化性状的影响,有得有失,关键是如何调整。Carpenter P.H.和Cooper H.R.(1927)认为,成龄茶园中耕作次数不宜多,甚至可以为松土或除草所代替。Enden T.(1940)认为,良好适度的茶园中耕,有利于降低土壤紧实度,促进茶树吸收根的增长。Enden T.(1949)还认为,过多过细的茶园耕作,会使茶树根系损伤而导致减产。在肯尼亚,除浅耕外,经常性的茶园耕作已经消声匿迹。我
The impact of tea farming on soil physical and chemical properties, gains and losses, the key is how to adjust. According to Carpenter P.H. and Cooper H.R. (1927), the number of tillage cultivated in mature tea gardens should not be more than enough to replace tillage or weeding. Enden T. (1940) argues that good and moderate cultivation of tea plantations is conducive to reducing soil compaction and promoting root absorption by tea plants. Enden T. (1949) also argues that too much care in the tea plantation can damage the roots of tea trees and lead to a decrease in yield. In Kenya, in addition to shallow plowing, recurrent cultivation of tea plantations has disappeared. I
