摘要
进行了适生固沙灌、草的选育,栽培以及减轻沿海热带气旋危害并延缓沙土向内陆移动速度等的研究.营造乔、灌、草综合治沙试验模式示范林,并筛选出防风固沙效果好的4个木麻黄优良无性系,3个灌木和5个适于林带前沿至高潮线沙带种植的草本植物;从林带前沿到农田旱地设置3道防风屏障.采取这些技术措施后,试验示范林内和林后风速降低43.5%～68.7%.4～5m/s风速已不再起飞沙,林内的自然植被增加,喜湿润的植物生长良好,防风固沙效果显著.
Suitable sand-fixation shrub and grass are selected and bred.In accordance with these technical barrier,the experiment selected 4 super casuarina equisetifolia clone and 3 shrubs with good sand-fixation and wind belt effect, 5 grasses that are suitable for the place from high-water mark to the tree belt front.Including the forest,3 wind-belt were established.With these measures,wind speed reduced 43.5%～68.7%,and there were no sandflying with speed 4～5*!m/s wind.Moreover,the quantity of natural vegetations in forest increased, clamp plant grow well.The experiment achieved remarkable effect.
