近年杂交水稻制种生产中,赤霉素用量增加,浙江钱江生化股份有限公司对赤霉素产品工艺和配方做了少量实验性调整,特别对原有的乳化剂进行了较大变动,研制了4种制剂在磐安县杂交稻制种田进行试验。目的是通过配方改进试验探索提高赤霉素对杂交稻制种效果的更加有效的途径,并降低生产成本。1材料与方法1.1材料本试验使用杂交稻制种组合为四川内江杂交水稻科技开发中心选育的内2优3015,研究使用的赤霉素由钱江生化股份有限公司生产提供。其中编号为4、5、7、8样品为通过调整乳化剂和其他辅剂后的新配方赤霉素,
In recent years, the hybrid rice seed production in the production of gibberellic acid increased, Zhejiang Qianjiang Biochemical Co., Ltd. of gibberellin product technology and formula made a small amount of experimental adjustments, especially the original emulsifier made a major change, the development Four kinds of preparations were tested in hybrid rice farming in Pan’an County. The purpose is to explore more effective ways to improve the effect of GA3 on hybrid rice seed production and to reduce the production cost through formula improvement test. 1 Materials and methods 1.1 Materials In this experiment, hybrid rice seed combination was selected to be Nei 2you 3015 in Sichuan Neijiang Hybrid Rice Science and Technology Development Center. The gibberellin used in this study was provided by Qianjiang Biochemical Co., Ltd. Among them, the samples No. 4, 5, 7 and 8 were the new formula gibberellins after adjusting emulsifiers and other auxiliaries,
