摘　　要：在春保护地黄瓜开花时，用ＢＮ－２的２５０倍或５００倍稀释液涂抹黄瓜子房，１９９７年１９９８年两年的试验结果表明：ＢＮ－２可保证黄瓜座瓜率达到１００％，而对照只有７４％或８８％。１９９７年比对照提高单瓜重２８．６％或２５．３％；１９９８年提高１５８％或１２２％。两浓度均能明显增加瓜条的粗度和长度，１９９８年分别增加６０％和５８％。１９９７年两浓度分别提高单株产量６６．９％和６６．７％。在果实的对数生长期，处理的生长速度约为对照的２倍。When cucumber plants covered with plastic membrane bloomed,ovary were smeared with 25 times or 500 times diluent of BN 2.The results in 1997 and 1998 showed that fruit set rate was induced up to 100%,compared with 74% or 88% in control;the fruit weight was increased by 28.6% or 25.3% in 1997 and by 158% or 122% in 1998;fruit diameter and fruit length were obviously increased by 60% or 58% in 1998;yield per plant was increased by 66.9% or 66.7% in 1997;growth rate in fruits logarithm growth stage was about two times as fast as control.
