2022年凤阳县水稻品种展示试验初报

凤阳县近几年种子市场销售的杂交水稻品种众多,农民选种是个难题。农业部门为了筛选出适宜当地大面积推广的高产、优质、广适的水稻品种,2022年征集了全县种植面积较大的35个品种参加展示试验。通过专人负责田间管理、田间观察记载、室内考种、总结等,得出结论：徽两优166、Y两优1577、N两优1133、晶两优1377、Q两优851、诺两优6号、天龙两优140、韵两优332、Y两优808、徽两优粤农丝苗等10个品种的抗逆性、丰产性、适应性较好,可以在凤阳县大面积种植推广。     

玉米抽雄期叶片与穗部性状及产量的相关性试验

This experiment was based on 11 maize cultivars and 1 control, including the leaf length, leaf shape value, the angle of leaf, stem and leaf, chlorophyll content and ear diameter, grain rows and yield. There was a close correlation between the length of leaf at ear position and the diameter of ear, that is, the diameter of ear, the number of rows of ear and the yield reached the maximum value when the leaf shape value was 8.3. The mean value of stem-leaf angle of leaves near the panicle site showed obvious correlation with ear diameter, number of rows and yield, that is, the varieties with large stem-leaf angle showed smaller ear diameter, fewer rows of grains and lower yield. There was a positive correlation between chlorophyll content and yield in tasseling stage. Share a collection Edit Delete More.
