棉花主动化调技术是唐山市科委的计划项目,由唐山市农科所承担。经4年试验研究,达到了预期目标要求,于1992年9日4日通过了专家鉴定。一致认为: 1.课题组在总结前人棉花化控经验的基础上,通过大量工作,在多种调节剂中筛选出96％的DPC,按棉花的生育期,结合长势,以不同次数、不同剂量进行主动调节,其技术路线合理,试验方法先进。 2.经过4年试验研究结果证明,通过主动化调,使棉花平均脱落率降低9.8
Cotton initiative transfer technology is the project of Tangshan Science and Technology Commission, undertaken by the Agricultural Science Institute of Tangshan City. After 4 years of experimental research, the expected target has been reached, and the expert appraisal was passed on the 4th of January, 1992. It was agreed that: 1. Based on the previous experience of cotton chemical control, the research group screened 96% of DPCs from a variety of regulators through a lot of work. According to the growth period of cotton and the growth of cotton, different times and different Active dose regulation, the technical route is reasonable, advanced test methods. 2. After 4 years of experimental research, it proves that by means of initiative adjustment, the average shedding rate of cotton is reduced by 9.8
