摘要:
在行上覆膜、行间覆膜及不覆膜3种不同处理下，对大豆根系在0～20 cm土层的水平分布和距主茎0～15 cm范围的垂直分布进行了系统研究。结果表明，随着土层深度和离主茎距离的增加，根系干重、活力、活跃吸收面积明显减少；同时，宽行分布根系的干重、活力及活跃吸收面积均高于窄行分布的根系干重、活力及活跃吸收面积。不同覆膜方式对根系干重和活力的影响表现为:行间覆膜>行上覆膜 >不覆膜;对根系活跃吸收面积的影响则表现为:行上覆膜>行间覆膜 >不覆膜。
Abstract:
The root vertical distribution of soybean in the range of 0~15 cm from stalk and the root horizontal distribution in 0~20 cm soil were researched systemically in 3 different film mulching treatments，which separately were film mulching on furrows(UPF)，film mulching beside furrows(SPF)，no film mulching(CK).The result indicated that the dry weight，the vigor and the active absorbing area of soybean roots reduced obviously with the increase of the soil depth and the distance to the stalk，meanwhile，the dry weight，the vigor and the active absorbing area of soybean roots in wide rows were higher than those in narrow rows.The root dry weight and the root vigor in different film mulching treatments were SPF>UPF>CK，but the active absorbing area of soybean roots were UPF > SPF > CK.
