高温胁迫下水肥耦合对高羊茅生态性状的影响
Effect of water and fertilizer coupling on ecological characters of Festuca arundinaceaunder heat stress
摘要
Abstract
This paper designed the low, middle and high water levels and three levels of nutrients with pot test under controlled conditions, studied the impact of different methods of water and fertilizer coupling on the ecological characters of tall fescue (Festuca arundinecea cv.Barlexas) under high-temperature (38/30 ℃, day / night) stress. The results showed that water and nutrients and the coupling effect had a remarkable impact on the ecological characters of tall fescue, the method of coupling water and fertilizer was better than single irrigation. The best way of coupling water and fertilizer was medium water and fertilizer (f2w2), it maximized to improve the ecological characters of the tall fescue, and prolonged the green period under heat stress, but inadequate water and basin irrigation or insufficient or too much nutrients were not benefit to the growth of tall fescue, and the moisture had greater effect on tall fescue than fertilizer under heat stress.关键词
