摘 要:以3、5、7年种植年限枣园土壤为研究对象,按照枣树冠幅内、外一周取0~20cm和20~40cm各4个土样混合,分析土壤微量元素含量,并对不同年限土壤微量元素含量变化特征进行研究。结果表明:3、5、7年果园中土壤微量元素中有效硼、铜、铁、锰、锌随着种植年限而降低,但随着枣树的生长,深层土壤微量元素下降反而能更为迅速;冠幅外土壤微量元素均高于冠幅内,随着枣树的生长,尤其是5年生长期后的枣树,更应加强对微肥的实施。Taking three years,five years,seven years of jujube orchard planting soil as materials,according to the jujube tree canopy within and outside week depicting 0-20 cm and 20-40 cm soil samples,each 4mixed analysis of trace elements in soil,and soil characteristics of trace element content in different years were studied.The results showed that,in 3years,5years,7years orchard,soil available trace elements boron,copper,iron,manganese,zinc decreased as planting years,but with the growth of jujube,deep soil trace elements could drop more rapidly.Outside canopy soil trace elements were higher than the crown,described as the jujube tree growth,jujube growing especially after five years,it should strengthen the implementation of the trace fertilizer.
