摘 要：
[目的]为解决干旱荒漠区沙丘造林成活率低的技术难题,从荷兰Groasis引进Waterboxx保水、节水造林器及技术,并分析其应用效果。[方法]在甘肃省民勤县流动沙丘和半固定沙丘上,用梭梭、花棒、柠条锦鸡儿、柽柳等固沙植物进行造林试验,采用直观统计观测的方法,研究Groasis Waterboxx在沙丘上造林后的风蚀、温度、保水和苗木成活率情况。[结果](1)春季用Groasis Waterboxx沙丘造林技术,流动沙丘风蚀情况比半固定沙丘严重2.0~6.0倍,造林效果差;从沙丘迎风面不同部位的风蚀情况来看,流动沙丘和半固定沙丘总体均表现为:顶部>中部>底部;(2)Groasis Waterboxx沙丘造林技术在高温季节能有效降低苗木根际土壤地温近50%,保护苗木免受高温灼伤,促进苗木生长;低温季节还能有效保持根际表面地温在5℃左右,防止苗木遭受低温冻害;(3)Groasis Waterboxx沙丘造林技术能使苗木周边0—40cm表土层含水量长期保持在6%~12%,保证苗木成活期的水分持续供给;(4)Groasis Waterboxx沙丘造林技术能显著提高苗木成活率30%~60%。[结论]Groasis Waterboxx沙丘造林技术在半固定沙丘造林效果优于流动沙丘,能够显著提高苗木成活率。

摘 要：
[Objective]Groasis Waterboxx and technology from Holland were introduced to solve the problem of sand dunes afforestation,and the technology application were analyzed.[Methods]Desert plants such as Haloxylon ammodendron,Hedysarum scoparium,Caragana korshinskii,Tamarix chinensis and other sand-fixing plants were used in Groasis Waterboxx afforestation on the mobile and semi-fixed dunes.Wind erosion was observed after the waterboxx plantation,and the ground temperature,seedling survival rate,dry weight,soil water-moisture content were measured.[Results]In the case of spring afforestation on dunes with Groasis Waterboxx,the wind erosion degree of mobile dunes was 2.0~6.0times of the one of semifixed dune.Afforestation on mobile dunes was not as good as the one on semi-fixed dunes.Either for the mobile dunes or the semi-fixed dunes,the wind erosion degree on windward sides exhibited a normal rank at dune positions as:the top>the middle>bottom.(2)In terms of temperature effect,we observed that,inhigh temperature season,Groasis Waterboxx effectively reduced nearly 50% of soil temperature in the seedlings rhizosphere comparing with the one on bare ground.It can protect seedlings from high temperature burn;whereas in low temperature season,it maintained the rhizosphere surface ground temperature at about5 ℃,can prevent seedling from low temperature freezing injury.(3)Using Groasis Waterboxx afforestation on sand dunes,moisture content of 0—40cm topsoil was maintained to be a relative stable level of 6% ~12%,ensuring the seedlings a constant supply of soil water.(4)In the end,afforestation using Groasis Waterboxx on dunes significantly improved the seedlings survival rate by 30% ~60%,which may provide new idea and pattern to those difficult site conditions for afforestation.[Conclusion]Groasis Waterboxx afforestation is more applicable on semi-fixed dunes than on moving dunes.It can significantly increase the survival rate of seedlings.
