针对冬小麦夏玉米一年两作区生产上常因夏玉米收获较晚而导致冬小麦播种亦较晚,进而引起小麦产量降低的问题,探讨山西省南部播期配套播种方式的最优模式.研究基于山西省垣曲县晋垣惠农种植专业合作社的旱作麦田,研究了3种播种处理10月13日+小麦宽窄行机械化探墒沟播,10月23日+机械化垄盖地膜沟播,11月7日+机械化露地条播对小麦品种烟农21农艺性状、产量及干物质累积运转的影响.结果表明,抽穗前,垄盖地膜沟播有利于促根生蘖积累干物质,然后依次是探墒沟播和露地条播;灌浆期,探墒沟播小麦的茎高明显高于垄盖地膜沟播和露地条播,随灌浆进程推进,探墒沟播小麦的功能绿叶面积持续时间长,且灌浆高峰开始早,因而利于增加小麦穗粒质量,提高产量,比露地条播增产53%.探墒沟播方式在冬小麦夏玉米一年两作区的旱地麦田具有推广应用潜力.为我国一年两作区旱地冬小麦建立一套适合的高产高效播种方式提供了理论依据.“,”After the late harvest of summer corn,the winter wheat planting is also late,which leads to the problem of reduced winter wheat production,and discusses the best mode for supporting seeding methods in the sowing season in Southern Shanxi Province. This study was based on the dry fields of Jinyuan Farming Cooperative in Yuanqu County, Shanxi Province.Three kinds of sowing treatments were conducted. On Oct.13th,wheat width and breadth mechanization was used to explore furrows,Oct. 23rd+mechanized ridge mulching,Nov.7th+mechanized open field sowing on the agronomic traits,yield traits and dry matter accumulation of Yannong 21. The results showed that before heading,the second sowing method was conducive to the accumulation of dry matter by rooting,followed by the first sowing method and the third sowing method;during the filling period,the stem height of the first sowing method was obvious above the second and the third sowing methods,the functional green leaf area of the first sowing method lasted for a long period of time as the grain filling progressed,and the peak of the grain filling started earlier,which was beneficial to increase the grain weight of wheat and increase the yield. The first method increased the yield by 53% over the third method. The first sowing method has the potential for popularization and application in dryland wheat fields in the two cropping areas of winter wheat and summer maize. The study provided a theoretical basis for the establishment of a suitable high-yield and high-efficiency sowing method for winter wheat in dryland of the two cropping areas in China.
