表1.噻苯隆与芸苔素内酯复配对高粱生长调节综合测定汇总表
Figure PCTCN2016079851-appb-000002
Figure PCTCN2016079851-appb-000003
注：表格中“芸”为“芸苔素内酯”缩写，“噻”为“噻苯隆”的缩写。施药时期：喇叭口初期，该阶段高粱植株未发生开始发生高粱褐斑病。施药次数：2次，施药间隔期8天；施药方式：茎叶喷雾；调查时期：高粱抽雄初期；本试验中，株高、茎径、发病指数、籽粒千粒重等指标均为各处理的平均值。
通过实验发明人发现，噻苯隆与芸苔素内酯之间具有很好协同提升作用，噻苯隆与芸苔素内酯混配在不同配比下，相对噻苯隆、芸苔素内酯单剂，以及清水对照，对高粱的生长调节作用明显，主要表现在：1、本发明可有效增加高粱的株径，提升植株上下营养传导能力，而且通过促进株径，可以提高高粱生长的抗倒伏性能；2、噻苯隆在作为单剂使用时对植物生长具有一定的抗病抗逆作用，而芸苔素内酯属于植物内在生长激素，对作物病害具有一定免疫力，芸苔素内酯与噻苯隆之间共同施用具有良好的协同作用，从上表分 析可以看出，噻苯隆与芸苔素内酯之间协同作用对高粱褐斑病的预防效果相对于单剂及清水对照，具有很好的预防效果；3、本发明可有效调节高粱的控旺徒长，即降低高粱株高和穗位，有效平衡营养生长与生殖生长的关系，防止倒伏；4、由于高粱生长前期噻苯隆与芸苔素内酯的协同作用，促进了高粱植株的营养传导、抗病抗逆，在高粱成熟期，对高粱的千粒重以及单位亩产有显著的提升作用，亩产提高率最高达到17.22％；5、噻苯隆与芸苔素内酯在配比(5.2-1000)：1之间时，所表现的两者协同增效作用效果明显，当噻苯隆与芸苔素内酯的比值低于5.2时，两者的协同增效作用效果不明显。
(二)田间药效验证试验
1、噻苯隆与芸苔素内酯混配对燕麦作物调节生长及抗病增产的田间综合试验
施药时期：燕麦灌浆初期，燕麦扬花期易发生白粉病等病害。
施药次数：1次。利用本发明的制剂实施例进行喷施，三个重复，结果取平均值。
表2噻苯隆与芸苔素内酯混配对燕麦调节生长的田间综合实验
Figure PCTCN2016079851-appb-000004
从表2实验数据显示，本发明的产品在燕麦扬花期施用，可以有效调节燕麦的健康生长。主要表现为：1、可以提升燕麦的穗长，提高穗粒数；2、可显著提高燕麦籽粒的重量； 3、可以矮化燕麦植株，有效控制燕麦控旺徒长，防止小麦倒伏；4、噻苯隆对燕麦的生长具有一定的促进作用，而芸苔素内酯对燕麦生长具有一定的抗病抗逆能力，两者混配后具有一定的协同增效作用；5、本发明的组合物对燕麦的单位产量具有显著的提升作用。
