玉米健壮素是江苏省淮阴市农科所研制的一种用于叶面喷施的植物生长调节复配剂。目前在我国的华北、华东地区推广面积较大。为了搞清玉米健壮素在辽宁省的应用效果,我们辽阳市农科所在1991、1992年进行两年试验。结果表明,健壮素对玉米有明显的增产效果,并以在14片叶时喷施,溶液浓度为600—800PPm效果最佳。增产率为13％左右。调查结果证明,健壮素对玉米具有“五增加、三降低、一缩短”的作用,是玉米增产的主要原因。
Corn is a healthy element of Huaiyin City, Jiangsu Province, developed by a branch for the foliar spray plant growth regulating compound. Currently in our country in North China, East China to promote a larger area. In order to find out the application effect of Cornstarch in Liaoning Province, we conducted a two-year trial in 1991 and 1992 in Liaoyang. The results showed that the sclerosing hormone had a significant yield increasing effect on corn and sprayed at 14 leaves with the best concentration of 600-800ppm. Yield increase rate of about 13%. The survey results show that Jianliang Su has the effect of “Five Increases, Three Decreases, One Shortening” on corn, which is the main reason for the increase of corn yield.
