【摘要】 为迅速改变杨树栽培低产现状，利用小试研究成果，采用丰产综合技术措施，于１９８３～１９９３年在辽西“三北”干旱地区进行了杨树速生丰产栽培技术开发试验。结果表明，采用“三大一深”方法栽植，对幼林实行施肥灌水、除草松土、抹芽除萌、树盘培土、修枝等配套综合措施，林木生长迅速，与同等条件一般造林相比，生长量提高３～５倍。更多还原

【Abstract】 In this paper,for changing the low yield status of poplar stands rapidly,fast growing high yield exploiting experiments of poplar were carried out in “Three North”arid regions of western Liaoning from 1983 to 1993 by using small scale test research results and comprehensive harvest technique measures. The results showed that:resorting to“Three big One deep”planting methods,and taking a complete set of measures such as fertilization,irrigation, weeding, loosening soil,removing buds and shoots,ridging tree pits and pruning,the young woods grew fast, and the growth increased by 3～5 times as compared with common afforestation on the same condition.更多还原
