1970—1977年,作者对西宁北川地区丰产麦田的群体光分布规律,各生育期叶面积指数控制指标,不同群体结构类型和栽培管理侧重点之间的制约关系,作了较系统的观察研究。指出小麦亩产1000—1300斤,籽实产量光能利用率在0.9—1.20％之间,生物学产量光能利用率在2.30—2.90％左右。灌浆—腊熟阶段,最高光能利用率达3.51％。在总结农民经验的基础上,结合光能利用的研究,摸索出春小麦高产栽培技术要点。
From 1970 to 1977, the author made a systematic observation on the light distribution rules of large-yield wheat fields in Beichuan region of Xining, the control index of leaf area index in each growth period, the types of different groups and the emphasis of cultivation management. Pointed out that 1000-1,300 kg per mu of wheat, seed yield of solar energy utilization rate of 0.9-1.20%, the biological yield of light energy utilization rate of 2.30-2.90%. Grouting - waxing stage, the maximum light energy utilization rate of 3.51%. On the basis of summing up the experience of peasants, combined with the research of light energy utilization, the key points of high-yielding spring wheat cultivation techniques were explored.
