本文分析了我所1971—1979年秋播油菜不同密度和种植方式试验研究材料,明确在中等肥力条件下,不同品种的种植密度与产量的关系,密植与田间小气候的变化,密植对油菜的生长发育及光能利用的影响,以及不同种植方式对产量的影响。试验品种采用“军农一号”和“淮油6号”,密度8000—20000株,设4—5个密度处理。种植方式采
In this paper, we analyzed the experimental data of different planting density and planting methods of rape in autumn from 1971 to 1979, clarified the relationship between planting density and yield of different varieties under medium fertility conditions, the changes of close-planting and field microclimate, and the close planting on the growth and development of rape And the impact of light energy utilization, as well as the impact of different planting methods on production. Test varieties using “Junun One” and “Huaiyou 6”, the density of 8000-20000, set 4-5 density treatment. Planting methods mining
