【摘要】 用奥普尔(OPAL)HA202对早花菜心进行浸种和喷叶,以提高菜心产量。结果表明:施用OPAL HA202的菜心小区平均产量834g,比施用清水的对照增产41.4%,增产极显著,因为OPAL HA202增加了菜心的株高、叶片开展度、茎粗和茎叶干物重。与之对比施用吲哚丁酸(IBA)的菜心小区平均产量675g,比清水对照增产14.4%,增产不显著。更多还原

【Abstract】 The seeds were soaked and the leaves were sprayed with OPAL HA202 to increase the yield of early flower Brossica Chinensis.The results were as follows: the plot yield average of early flower Brossica Chinensis used by OPAL HA202 was 834g,41.4% higher than the plot yield average of CK used by water,this yield difference reached significant level in statistics,because the plant height,the distance between two leaves in the top of the plants,the stem diameter and the weight of dry material of the stems and leaves were raised by OPAL HA202.But the plot yield average of early flower Brossica Chinensis used by IBA was only 675g,14.6% higher than the plot yield average of CK used by water,this yield difference did not reached significant level in statistics.更多还原
