Effects of different mulching on the establishment of Cleistogenes songorica

Abstract

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.
