2002年对浙江省部分茶园锰调查结果表明,浙江省茶园全4锰含量0～20cm土层,平均为357.33±265.26mgkg-1,20～40cm土层,平均为361.69±268.69mgkg-1。有效锰含量0～20cm土层,平均为51.16±30.16mgkg-1,20～40cm土层,平均为38.32±25.85mgkg-1,约占全锰含量的15%左右,茶园缺锰率约占30%左右。从上下土层来看,表现出上层锰含量要比下层高。茶树吸收锰与土壤有效锰含量呈极显著正相关,随着叶片的成熟度增加,锰积累增加,同时茎干部也是锰累积的部位。土壤有效锰含量与土壤pH、Al、成土母质有关。
The results of the survey on some tea gardens in Zhejiang Province in 2002 showed that the average manganese content in 0 ~ 20cm soil layer of tea plantations in Zhejiang Province was 357.33 ± 265.26mgkg-1 and 20-40cm soil layers, with an average of 361.69 ± 268.69mgkg-1. The effective manganese content of 0 ~ 20cm soil layer, with an average of 51.16 ± 30.16mgkg-1, 20 ~ 40cm soil layer, with an average of 38.32 ± 25.85mgkg-1, accounting for about 15% of the total manganese content, manganese deficiency rate of about 30% %about. From the top and bottom of the soil, showing the upper manganese content higher than the lower. There was a significant positive correlation between the uptake of Mn by the tea plant and the available Mn content in the soil. With the maturity of the leaves increasing, the accumulation of Mn increased, while the stems and stems were also the accumulations of Mn. Soil available manganese content and soil pH, Al, soil parent material related.
