为探讨夏玉米高产途径,提高玉米产量,1975年我们在我省中南部6个地区、14个县(市),与23个生产大队的贫下中农相结合,开展了夏玉米高产栽培联合试验和调查工作。各单位的试验面积大小不等,采取的栽培措施主要是小品种、高密度、大小行、沟播等,获得良好效果。亩产800斤以上的有11个大队,其中有2个大队亩产千斤以上。1976年继续在网点进行试验,14个点试验面积217亩,平均亩产606斤,高产试点亩产900斤以上,如藁城县良村10亩京早2号亩产907.8斤;晋县留村用2608×白苏635单交种搞的6.3亩高产田,平均亩产857.5斤。两年的试验表明,小品
In order to explore the high-yield summer maize production and increase the corn yield, we carried out the joint trial of high-yielding summer maize in combination with 6 middle-south areas and 14 counties (cities) in south China in 1975 with the poor and middle peasants of 23 production groups and Investigation work. The test area of each unit varies in size, and the cultivation measures adopted are mainly small variety, high density, large and small rows, furrowing, and the like, and obtain good results. There are 11 brigades with a production of more than 800 kilograms per mu, among which two have more kilograms of mu per mu. In 1976, the experiment was continued at the outlets. The test area of 14 spots was 217 mu with an average yield of 606 jin and a yield of more than 900 jin per mu. For example, 10 mu of Liangmu Liangmu 10 mu per mu was 907.8 jin per mu. Jingjin 2 Village with 2608 × white Su 635 single cross-breeding engage in 6.3 acres of high-yield fields, the average yield of 857.5 kg. Two years of testing shows that sketch
