沙棘适应性强,是和杨树、油松营造混交林的优良树种。杨树、油松和沙棘混交可增强防风固沙能力,增加土壤养分,提高土壤肥力;而且可以提高杨树、油松的生长量。混交林中的杨树平均树高为杨树纯林的2.6倍、胸径为2.5倍,且树干弯曲度小。沙棘与油松混交后,除提高油松的生长量外,还可减轻松毛虫的为害。 Sea buckthorn adaptable, and poplar, Pinus tabulaeformis hybrid tree to create an excellent species. Poplar, Pinus tabulaeformis and seabuckthorn mixed can enhance windbreak and sand fixation, increase soil nutrients, improve soil fertility; but also can increase the growth of poplar, Pinus tabulaeformis. The average height of poplar in mixed forest is 2.6 times that of poplar pure forest, and the diameter at breast height is 2.5 times, and the trunk curvature is small. Seabuckthron and pine mixed, in addition to increasing the growth of Pinus tabulaeformis, but also reduce the damage caused by pine caterpillars.
