| 摘 要： | 在石羊河下游干旱荒漠区开展沙蒿人工模拟飞播造林试验.结果表明:1)从播种时间来看,7～9月为沙蒿人工模拟飞播适宜造林期,8月为最佳时期,其它时期均不适宜；2)从地类来看,草沙障压沙地、丘间低地和半固定沙丘适合人工模拟飞播,而流动沙丘不适宜；3)沙蒿人工模拟飞播造林受高温、干旱、大风和降水量等综合因素影响大,且播种当月降水量低于10 mm是人工模拟飞播造林成功的限制因子.

| Abstract: | Experiment on man-made simulated plane sowing afforestation of Artemisia desertorum in arid desert region of the Lower of Shiyang River.The results showed: 1) Sowing time from July to September was suitable for man-made simulated plane sowing afforestation of Artemisia desertorum,August was suitable for afforestation period,August was optimum month and other months were not suitable;2) Sand land with straw checkerboard barriers,inter-dunal lowland and semi-fixed sand dune were suitable for man-made simulated plane sowing afforestation of Artemisia desertorum,and mobile sand dunes was not suitable for man-made simulated plane sowing afforestation of Artemisia desertorum;3)The influences of comprehensive factors such as high temperature,drought,wind and precipitation on man-made simulated plane sowing afforestation of Artemisia desertorum was great,man-made simulated plane sowing afforestation of Artemisia desertorum was successful when the precipitation was less than 10 mm during sowing month. |
