为解决玉米因倒伏、染病造成的减产问题,本研究以油菜素内酯(Brassinosteroids,BRs)具有高效、无毒、提高植物抗性、改善株型、提高光合性能等特点为理论基础,结合乙烯利能控高、提高抗性的特点,复配了一种控高、抗倒伏的生长调节剂。玉米的田间试验表明:这种复合生长调节剂能明显降低玉米高度、提高秸杆粗度、促进气生根及侧根的发育、增加玉米叶片叶绿素含量,达到了控高、抗倒伏、增产的目的。
In order to solve the problem of yield reduction caused by lodging and disease of maize, Brassinosteroids (BRs) are highly efficient, non-toxic, improve plant resistance, improve plant type and improve photosynthetic characteristics. Based on the theoretical basis, Lee can control high, improve the characteristics of resistance, with a control of high, lodging of growth regulators. Corn field experiments showed that: the compound growth regulator can significantly reduce the height of corn, increase the coarseness of straw, promote the development of aerial roots and lateral roots, increase the chlorophyll content of maize leaves, and achieve the purposes of controlling high, lodging resistance and increasing yield.
