玉米是高产作物,田间试验多以小区种植株数为研究对象,由于受自然环境因素的影响,试验缺株的现象难以避免,如何对缺株进行正确的收获及其对产量影响的正确估计是提高玉米田间试验质量的重要问题。本研究在于探讨缺株正确的收获估产方法,为玉米田间试验提供参考依据。1 材料与方法试验于1991～1992年在河南省黄泛区农场农科所夏直播条件下进行。供试品种为竖叶中穗型品种“予玉2号”和河南省农科院
Maize is a high-yielding crop. In field trials, the number of planted trees in a plot is mostly used as the research object. Due to the influence of natural environmental factors, the phenomenon of lack of tested plants is unavoidable. How to properly measure the deficient plants and estimate the effect on yield is improved An important issue in the quality of corn field trials. The purpose of this study is to explore the method of estimating the yield of the missing plant and to provide a reference for the field experiment in corn. 1 Materials and methods The experiment was conducted in 1991-1992 under the summer seeding conditions of the farm farmyard in the Yellow River in Henan Province. The tested varieties were vertical leaves middle ear type “Yu Yu 2” and Henan Academy of Agricultural Sciences
