中文摘要	[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040 cm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。
英文摘要	[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 2.0~6.0 times 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, in high 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 about 5 ℃,can prevent seedling from low temperature freezing injury. (3) Using Groasis Waterboxx afforestation on sand dunes,moisture content of 040 cm 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.
