| 摘 要： | 本实验用TRIME-TDR土壤水分测定系统在肥城市潮泉镇苹果园进行水分定位动态观测,分析秸秆覆盖和无秸秆覆盖下苹果树盘不同层次水分动态变化。研究结果表明:秸秆覆盖对树盘土壤含水量的影响主要表现在少雨季节(4~5月)和土壤浅层(0~40?);在多雨期(6~10月)和土壤深层(40~80?)对含水量影响不显著。秸秆覆盖能有效提高树盘表层土壤的含水量,使土壤水分在各土壤层之间的分配比无秸秆覆盖更均匀。

| Abstract: | By using soil moisture measurement system-TRIME-TDR,soil water position and dynamic observation were arranged in apple orchard in Chaoquan of Feicheng and water dynamical characteristics in different levels of soil with straw mulching and no straw mulching were analysised.It showed that: the effect that straw mulching made on soil moisture mainly performanced in dry season(approximately from April to May) and shallow soil(0-40 cm) while the effect was indistinctive in wet season(approximately from June to O... |
