摘要
化学固沙剂对柠条出苗的影响试验结果表明:随着化学固沙剂施用量的增加,柠条出苗时间有所增加,凋萎时间延长。所有化学固沙剂处理的柠条凋萎时间均比对照延长1~6 d,说明所用化学固沙剂均具有一定的保水能力。以任丘固沙剂出苗率最好,文安固沙剂出苗率最低,其他固沙剂出苗率与对照接近。柠条8月份出苗情况较6月份的好。
The result of a study of the effect of the chemical sand-fixing agent on the emergence of Caragana microphyUa showed that the emergence time of Caragana microphylla increased and the wilting time prolonged with the increased application rate of chemical sand-fixing agent. The wilting times of Caragana microphylla with all the treatments of various chemical sand-fixing agents were 1~6 days higher than that of the control, indicating that various chemical sand-fixing agents all have some water retention capacity. The emergence rate with Renqiu sand-fixing agent was highest and the emergence rate with Wen'an sand-fixing agent was lowest and the emergence rates with other sand-fixing agents were close to that of the control. The rate of emergence of Caragana microphylla in August was better than that in June.
