摘要
通过在榆林干旱地区,选择侧柏、樟子松、大扁杏、紫穗槐等树种,在不同的立地条件下,采用不同的造林技术措施进行造林试验,研究结果表明:只要采用预整地、选容器苗、适度深栽植、GGR灌根、覆膜套笼等5项关键技术措施,就能克服土壤干旱的问题,从而达到提高造林成活率的目的。
Platycladus orientalis(L.),Pinus sylvestris(L.),Armeniaca vulgaris(L.),and Amorpha fruticosa(L.) Endl were planted in Yulin as experiment under different sites and soil conditions by different planting methods of afforestation.The result showed that the survival rate of seedlings can be significantly improved by ways of treatment prior to planting,container seedling,proper depth of planting,use of GGR and mulching.
