摘  要：
本文研究了不同晾晒时间处理对平榛苗木相对含水量、成活率及生长量的影响。结果表明 :随着晾晒时间延长苗木根、茎、梢含水量都降低 ,其中以梢的降低幅度最大 ,茎和根次之 ,说明平榛根蘖苗的根比茎和梢的保水能力强 ;苗木成活率随晾晒天数的增加总体上呈下降趋势 ,4月份各处理的苗木成活率的下降幅度最大 ,从 80 %下降到0 ;晾晒时间越长 ,新梢生长量、叶片数、萌芽数降低幅度越大。

摘  要：
The effect of different treatment of drying in the air on relative water content, planting survival rate and growth of Hazelnut seedling was studied. The results showed that the water content in root, stem and shoot all decreased with the increase of drying time, the content in shoot decreased most greatly and that in root decreased lest, which demonstrated that the capability of root to hold water was bigger than that of stem and shoot; the seedling survival rate became lower with the increase of drying days.In April,the rate decreased mostly, from 80% to 0; the growth of new shoot, the number of leaves and the new buds dropped with the increase of drying time.
