摘要: 在玉米第10至12片叶展开时使用10%乙烯利可溶性粉剂600mg/L,700mg/L和800mg/L喷雾,可使玉米植株明显矮化;药后15d,用药玉米比对照矮36~41cm;玉米抽雄后用药玉米比对照矮60~78cm。当使用浓度上升到1000mg/L时,玉米产生明显药害。施用乙烯利后对基粗的影响不大,仅在施用后的初期对玉米基粗有一定增大作用。施用不同浓度的乙烯利后对玉米有一定增产作用,但增产幅度不如0.04%云大-120水剂0.02mg/L。由于乙烯利能明显使玉米植株矮化,在多风暴的地区使用还是有很大意义。

Abstract: In this paper, effects of Ethephon on growth and yield of corn, compared to Yunda-120(brassinolide), are studied. It makes corn plant obviously stunt when the corn plants are sprayed respectively with 10% Ethephon sp 600mg/L, 700mg/L and 800mg/L at the growing stage with 10~12 leaves:The height of treated plant is much shorter by 38~41cm than. Furthermore, the treated plant is stunted by 65~78cm than those untreated at the stage of earing. Although Yunda-120 also made the plant stunt, the function is not much stronger than ethephon. The effect of ethephon to the corn stem is very slight. It is to increase corn yield slightly when the different concentrations of ethephon are sprayed. The ranges of increasing yield are not so high as Yunda-120.
