摘要
采用分层分段挖掘法研究滴灌和自然条件下梨枣根系的空间分布状况。结果表明,2种条件下梨枣的吸收根在水平方向主要分布在0～30cm范围内,而在垂直方向主要分布在0～40cm土层;2种条件下梨枣的输导根在水平方向主要分布在0～30cm范围内,而在垂直方向,自然条件下的输导根主要分布在0～60cm土层,滴灌条件下的输导根主要分布在0～80cm土层。
The spatial distributions of Ziziphus jujube cv.Lizao roots under drip irrigation and natural conditions were researched by layered and sectioned digging method.The results showed that under the 2 conditions,the absorbing root of Z.jujube cv.Lizao was mainly distributed in the range of 0-30 cm in horizontal direction and in the soil layer of 0-40 cm in vertical direction,and its conducting root was mainly distributed in the range of 0-30 cm in horizontal direction.In vertical direction,its conducting root was mainly distributed in the soil layer of 0-60 cm under natural condition and 0-80 cm under drip irrigation condition.
