植物生长调节剂在水稻倒伏上的研究进展

Research Advantage of Plant Growth Regulators on Lodging of Rice

针对水稻倒伏问题,从化控角度出发,介绍了几种植物生长调节剂在水稻倒伏上的应用情况。其中着重从水稻株高、茎粗、节间长等形态指标上诠释了植物生长调节剂的调控作用及机制,简要的分析了植物生长调节剂对水稻形态解剖微结构的影响,展望了化控技术的先进性,同时也提出了应用植物生长调节剂的不足之处。

In this paper, rice lodging problem in recent years and an overview of several plant growth regulators on lodging of rice from the chemical control perspective were introduced. The mechanisms of plant growth regulators were introduced through the analysis of rice morphology standard, such as plant height, stem diameter, intemode length, and so on. The effects of plant growth regulators micro-structure of morphology anatomy in rice were briefly analyzed, advance of control technology was prospected, the inadequacies in the application of plant growth regulators were raised, and finally a theoretical basis on lodging resistance of rice for the future study of chemical regulation was provided.
