【摘要】 历时10 a对蒙古栎母树林营建技术进行了研究,确定出营建母树林适宜初始年龄为50 a,适宜林型为坡地蒙古栎林、台地漫岗蒙古栎林,适宜坡向为阳坡、半阳坡.郁闭度0.7以上,树种组成6成以上,坡度小于20°.蒙古栎母树林遗传测定表明:蒙古栎母树林子代树高、地径遗传力分别为0.586 8和0.567 1,遗传增益分别为7.53%和5.4%,增产效果显著.更多还原

【Abstract】 Establishment technology of seed stand of Quercus mongolica was researched for ten years,the initial age of establishing seed stand was 50 a,the suitable forest types were Quercus mongolica in the slopes and platform,the suitable slope aspect was the sunny slope and semi-sunny slopes.The canopy density was above 0.7,tree species composition were above 6,slope degree <20°.According to genetics of seed stand of Quercus mongolica,progeny height and heritability of diameter of seed stand of Quercus mongolica were 0.586 8,0.567 1 respectively,heredity gain were 7.53%,5.4% respectively,stimulation effect was obvious.更多还原
