【摘要】 2008年秋季在内蒙古呼和浩特市和林格尔县、清水河县山地、丘陵区的干旱阳坡进行人工直播山杏、山桃造林试验。在播前播后实施工程性鼠害治理措施,鼠口密度共下降了85.3%~87.6%;直播造林从整地到抚育管理采用抗旱保苗技术措施,造林平均出苗率达到90%,平均保存率在85%左右。该项直播配套技术可用于半干旱区荒山丘陵的人工造林。更多还原

【Abstract】 In Autumn,2008,Prunus ansu and Prunus davidiana have been planted artificially by direct seeding in arid sunny slope in mountainous area and hilly area in Hohhot,Helingeer County and Qingshuihe County in Inner Mongolia.Rodent pest has been controlled before and after seeding with rodent density decreased by 85.3% to 87.5%.Measures of keeping seedling from drought have been adopted in direct seeding afforestation from soil preparation to tending management,with average emergence rate at 90% and average preserving rate at 85%.This kind of matching technology of direct seeding can be used in artificial afforestation in barren hills and hilly in semi-arid area.更多还原
