1984～1986两个年度,湖南省粮油生产局统一试验方案,组织益阳、娄底、常德、岳阳地(市)农科所等单位进行大麦不同施氮水平、密度、播种方式正交试验,以探讨我省大麦高产栽培技术及产量形成过程,为指导全省大麦生产提供科学依据。现将两年度各点试验情况与结果综述如下。 In the two years from 1984 to 1986, a unified experimental scheme of Hunan Bureau of Grain and Oil Production Bureau was organized to conduct orthogonal experiments on the different nitrogen application levels, densities and sowing methods of barley in the areas of Yiyang, Loudi, Changde and Yueyang prefecture (city) Barley high-yielding cultivation techniques and yield formation process in our province provide scientific basis for guiding the production of barley throughout the province. Now the biennial point test conditions and results are summarized below.
