近年来,我省小麦随着水肥栽培条件的改善,通过合理密植等高产配套技术的推广,使得小麦产量及经济效益有了明显提高。但中后期倒伏与高产的矛盾也日益突出,对小麦的稳产影响较大。为了解决高水肥地小麦高产与倒伏的矛盾,我们于1989年春季进行了小麦施用多效唑的试验,以探索防倒措施,完善小麦高产配套技术。 In recent years, with the improvement of water and fertilizer cultivation conditions in our province wheat, the yield and economic benefits of wheat have been significantly improved through the popularization of such high-yielding technologies as close planting. However, the contradiction between lodging and high yield is also increasingly prominent in the mid-late period, with a greater impact on the stable yield of wheat. In order to solve the contradiction between high yield and lodging of wheat with high water and fertilizer, we conducted a trial of wheat PP333 in the spring of 1989 to explore anti-dumping measures and improve the high-yielding wheat supporting technologies.
