试验了 8种水肥处理对地毯草、假俭草、竹节草 3种草坪草延迟冬绿期的效果。结果表明 :地毯草在冬季最需要水肥管理 ,铺施有机肥 +木糠 +砂处理可使地毯草产生最理想的冬季保绿效果 ,其它水肥管理措施则可延长绿期 1～ 2个月 ;多种水肥管理措施可使假俭草达到较理想的冬绿效果 ;竹节草受水肥管理的影响最小。不同水肥管理措施相比 ,4d灌水一次的效果好于 8d灌水一次 ,有机肥的效果优于无机肥 ,无肥的效果最差
Eight kinds of water and fertilizer treatments were tested on the effect of delayed greening period on three turf grasses including Carpetgrass, Centipedegrass, Scripus tricuspidata. The results showed that Carpetgrass was most in need of water and fertilizer management in winter. Applying organic manure + wood chaff + sand treatment could make Carpet grass produce the best greening effect in winter and other water and fertilizer management measures could extend the greening period by 1 to 2 months. A variety of water and fertilizer management measures can make the froggrass to achieve a more ideal winter green effect; Stem grass water and fertilizer management by the least. Different water and fertilizer management measures, 4d irrigation once better than 8d irrigation once, the effect of organic fertilizer is better than inorganic fertilizer, the effect of no fertilizer is the worst
