The supersaturation with respect to ice can be used to diagnose the vertical distribution of ice-water conversion area, then determine the seeding height.
其中，冰面过饱和度可诊断“冰水转化区”的垂直分布，进而为确定合适的播撒高度提供判据。

The spikelets and the setting grains per panicle and effective panicle number per unit land area all decreased with the delay of seeding times.
这可能是由于播种期的推迟，每穗总粒数、每穗实粒数和有效穗显著降低。

The dynamics of the plant height and the leaf area of seeding progeny of L. regale accroded with the growth trend"slow-fast-slow".
