摘要
2002年对浙江省部分茶园土壤钼进行了调查.结果表明,浙江省茶园土壤全钼含量较高,在0～20 cm土层为12.81±10.76 mg/kg,在20～40 cm土层为11.26±9.06 mg/kg,但有效钼含量低,缺钼茶园占到了50%以上,其中严重缺钼茶园在45%以上(且有效钼含量只占到全钼含量的3%～12%).统计分析显示,土壤有效钼(x)与全钼(y)之间有着极显著线性正相关,y＝4.5679x+5.8135(n＝63,r＝0.816**). 从上下土层看,表现出0～20 cm土层钼含量要比20～40 cm土层高.茶园土壤有效钼含量与土壤有机质含量呈显著相关.
The available Mo, total Mo content, soil pH and organic matter content in partial tea garden soils taken from Zhejiang province were determined. The results showed the tea garden soils contained a total Mo content of 12.81 ± 10.76 mg/kg in 0 ～ 20 cm depth, and 11.26 ± 9.06 mg/kg in 20 ～ 40 cm depth. From the results, the available Mo content approximately accounted for 3% ～ 12% of the total Mo.According to critical value of 0.3 rng available Mo per kg soil, the depletion rate of the Mo content in tea garden soils from Zhejiang province was more than 50%. In comparison, the the depletion rate of the Mo content in tea garden soils from Zhejiang province was more than 50%. In comparison, the Mo content in 0 ～ 20 cm depth were higher than in 20 ～ 40 cm depth. It was clear from the results that a high correlation was found between the available Mo content （x） and the total Mo （y） in tea garden soils, expressed as： y = 4.5679x ＋ 5.8135 （n = 63, r= 0.816 ）。 The available Mo content in tea soils were correlated to the pH, organic matter et al, thus the soils with low in organic matter, strongly acidic, and low activation rate of Mo led to reduce the availability of Mo.
