摘要: 覆盖物处理对无芒隐子草建植的影响因土壤干旱条件不同而异,在非干旱条件下(隔5 d灌溉),各处理对建植率的影响差异不显著。但在干旱条件下(隔15 d灌溉),沙覆盖的建植率(40.7%)显著高于其他处理;地膜覆盖(23.6%)与对照(22.2%)无显著差异,但显著高于稻草覆盖(15.9%)。2种灌溉条件下,沙覆盖处理的株高、叶片数、分蘖数、叶面积和地上生物量等都显著高于其他处理和对照。

Abstract: Effects of different mulching on the seedling establishment of Cleistogenes songorica varied with soil water conditions. The mulches showed no effects on seedling establishment when the plants were irrigated every 5 days, but it significantly affected seedling survival rate when the plants were irrigated every 15 days. At 15-day interval irrigation, the seedling establishment rate was the highest (40.7%) under sand mulching and was the lowest (15.9%) under straw mulching. The seedling establishment rate under film mulching (23.6%) was not significantly different from that of the control (22.2%), but was significantly greater than that under straw mulching (15.9%). The plant heights, leaf numbers, tiller numbers, leaf areas and aboveground biomasses under sand mulching were significantly greater than those under other treatments.
