摘要
本文主要介绍了藏青13号的选育目标、过程、品种特征特性、主要优缺点、栽培技术要点及2012-2013年在尼木、曲水、日喀则等地进行生产示范,通过田间记载和室内考种结合的方法对品种进行综合评价和藏青13在不同生态区域与对照:藏青320的产量比较分析,总结出了新品种在不同生态区域的适宜情况和青稞单产水平的提高,使科技新成果、新技术在农业生产中达到了增产增效的目的。
This paper focuses on the effect of photosynthesis on wheat yield, especially the re- lationship between photosynthesis rate and grain yield of wheat . In this paper, through the discussion of Fertilization on Photosynthesis and different tillage on wheat flag leaf photosynthet- ic characteristics and water use efficiency and wheat root extended depth of flag leaf senescence and photosynthetic product distribution of summary of the impact of the photosynthesis of wheat on the yield variation, and introduces the wheat most production from photosynthesis , and photosynthesis in the late period of wheat growth contribution to grain can reach above 80%. And tell us, in the actual production process, to take the best cultivation and management meas- ures, so as to achieve a higher yield.
