摘要
通过试验及田间观测,提出了在500mm~600mm的正常降水年份渭北旱地小麦产量4500kg/hm2、6000kg/hm2的产量构成指标、群体动态变化指标、叶面积动态变化指标、群体生长率与干物质累积动态指标和不同生育时期的苗情指标。
Based on the experiments and field observation, at the normal year with a pricipatation of 500 mm~600 mm and wheat yield of 4500 kg/hm 2 and 6000 kg/hm 2, wheat yield formation index, population dynamic change index, leaf surface dynamic change index, dynamic index of population growth rate and dry matter accumulation, and the index of seedling grow condition at different stages are proposed respectively,and their adjustment and control measures are also put forward.
