叶面宝是广西化工研究所研制的一种新型复合植物生长调节剂,于1985年通过省级技术鉴定。为了探讨叶面宝在小麦上的增产效果和施用技术,我们在小麦上进行了试验。试验设6个处理,3次重复,随机排列,经方差分析和多重比较,结果表明,小麦喷施叶面宝有显著的增产效果,值得在生产上示范推广。一、增产效果。试验结果表明,在小麦孕穗期,抽穗20％时,分别喷施叶面宝1次和孕穗期及抽穗20％时各喷1次叶面宝,均有不同程度的增产效果,亩平增产幅度21.2—37.0公斤,增产率7.0—12.1％。以孕穗期及抽穗20％时各喷1次叶面宝的增产效果最好,其次是孕穗期喷施1次
Yemianbao is a new type of compound plant growth regulator developed by Guangxi Institute of Chemical Technology and passed the provincial technical appraisal in 1985. In order to investigate the yield-increasing effect and the application technology of the leaves on wheat, we conducted experiments on wheat. The experiment set 6 treatments, 3 repetitions, random arrangement, analysis of variance and multiple comparisons. The results showed that wheat foliar application of a significant increase yield effect, it is worth in the production of demonstration and promotion. First, increase production efficiency. The results showed that in the booting stage of wheat, when heading 20%, spraying foliar 1, booting and 20% heading 1 foliar, each had different degrees of yield increase, mu yield increase 21.2-37.0 kg, increase rate of 7.0-12.1%. When the booting stage and heading 20% spray 1 foliar spray the best yield effect, followed by spraying booting stage
