库尔勒香梨年生长期生物量及养分积累变化规律

Annual biomass and nutrient accumulation of Korla fragrant pear

  • 摘要: 以6年树龄的库尔勒香梨为试材,对香梨树生物量及养分吸收规律进行了研究。结果表明,年生长期内香梨单株树体干物质、氮、磷、钾的积累量均随生育期的推进呈增长趋势,与萌芽前期相比,分别增加5804.92 g、75.71 g、27.11 g和103.10 g。其中膨果期的积累量和积累速率都较大,干物质、氮、磷、钾的积累量分别占积累总量的53.52 %、 22.93 %、 44.04%和62.66%。库尔勒香梨每生产1000 kg 果实需要吸收氮(N)7.52 kg、磷(P)4.29 kg和钾(K)6.05 kg。

     

    Abstract: The annual biomass and nutrient absorption of Korla fragrant pear tree were studied using 6 year old Korla fragrant pear tree. The results show that the cumulative amounts of dry matter, N, P and K per single plant are increased with the growth and development of Korla fragrant pear, and compared with the early bud stage, which are increased by 5804.92 g, 75.71 g, 27.11 g and 103.10 g, respectively. The accumulation contents and accumulation rate are the biggest at the fruit expanding stage, which account for 53.52%, 22.93%, 44.04% and 62.66% respectively.To attain 1000 kg economic yield, Korla fragrant pear trees should uptake N 7.52 kg, P 4.29 kg and K 6.05 kg.
