织女还把从天上带来的天蚕分给大家，并教大家养蚕，抽丝，织出又光又亮的绸缎。
氮素在开花前主要分布在叶片中，在开花后开始由叶片逐渐向果穗转移。
利用冠层反射光谱监测叶片碳氮比的适宜时期为孕穗期至吐丝期。
控制适宜的最大LAI，增加花后光合势所占比例，是高产强源的保证。
灰斑病菌在抽丝期期间或结束后损害叶片，导致严重减产。
“甘为春蚕吐丝尽，愿化红烛照人寰”，我誓将青春献杏坛，甘洒热血哺新苗！
1·Spring maize grain starch content changed as a single peak curve after silking.
春玉米籽粒淀粉组分吐丝后呈单峰曲线变化。
2·It could simulate the morphological change of maize from emergence through silking, and the figure was drawn on the screen, Meanwhile, tassel initiation and root development information were shown.
它能够模拟出玉米从出苗到吐丝期间的形态变化过程，在计算机上绘出植株形态图。
3·The results showed that the greatest bulk density values appeared in the 49th day after silking , and harvest later had influence on the grain bulk density.
从试验结果分析，容重最高值出现在吐丝后49天，晚收影响籽粒的容重。
4·The proper time for monitoring leaf soluble sugar to nitrogen ratio should be from booting to silking stage.
利用冠层反射光谱监测叶片碳氮比的适宜时期为孕穗期至吐丝期。
5·The N absorption proportion after silking stage was 40.30%-47.78% of the total, so it was important to provide maize plants with sufficient N in later growth stage for realizing super-high-yield.
超高产夏玉米吐丝后氮素吸收积累量占总积累量的40.30%-47.78%，保证后期氮素养分充足供应对于夏玉米达到超高产水平至关重要；
