【摘要】 经过连续三年利用DBOL保水剂对山杏裸根苗造林及幼林生长的试验研究,结果表明:(1)山杏裸根苗造林保存率提高10.5%～14.5%;(2)山杏幼林高生长量增加41.3cm～53.0cm,地径生长量增加1.83mm～2.05mm;(3)山杏幼树提早15天左右萌动,延迟10天左右停止生长;(4)山杏幼树营养生长增强,生殖生长减弱。更多还原

【Abstract】 Three-year continuous observations of the growth and the root development of Prunus armeniaca in arid areas on the application of DBOL have shown as follows: 1) the survival rate of its naked seedlings after planting increased by 10.5%～14.5%; 2) its height increment rose by 41.3cm～53.0 cm and its diameter above the ground reached more 183 mm～2.05 mm than before; 3) its germination date advanced earlier 15 days than that of CK and its growing season also delayed more 10 days than that of CK; 4) its nutritional growth was strengthened and its genital development was weakened.更多还原
