As compared with the traditional irrigation-traditional fertilization, the following results of the improved traditional irrigation-optimized fertilization were obtained: reduced tiller number per unit area, lower percentage of the tiller ear number/the tiller number, the decreased ear number per unit area, the greatly reduced grain number per ear (1999-2000) and like weight of 1, 000 grains; almost the same plant height; shorter base internode length, a bit more weight per unit internode length, longer internode length under ear; lower LAI values in middle and later stages; coincident process of dry matter accumulation from straight growth onwards, a little more dry matter accumulation amount from earing to maturity; shorter and thicker flag leaf, 2〓 leaf, 3〓 leaf and 4〓 leaf from top, reduced total area of these leave; bigger mean canopy leaf tilt angle, smaller light extinction coefficient , higher ratio of light penetration in the upper, middle and lower parts of the wheat canopy, and tighter plant type; almost identical dynamic change of flag leaf chlorophyll content; and almost the same root amount in 0-120cm soil layer, smaller rate of progressive decrease of the root length density and root weight density with soil getting deep and relatively increased root amount in deeper soil layers.
在传统灌溉-优化施肥条件下,冬小麦单位面积总分蘖数比传统水肥减少,成穗率降低,单位面积穗数有所减少,穗粒数、千粒重无显著性差异;株高基本无变化;基部节间长度缩短,充实度略微增高,穗下节间增长;中后期叶面积指数略低于传统水肥;起身至成熟干物质积累量动态变化过程与传统水肥十分接近,但抽穗至成熟形成的干物质量增加;旗叶、倒2叶倒3叶、倒4叶叶长及总叶面积有所减少,叶片相对增厚;冠层平均叶倾角大,消光系数小,冠层各层的透光率较高,株型紧凑;旗叶叶绿素含量动态变化与传统水肥十分接近;0-120cm土层总根量与传统水肥也差异不大,但根长密度和根重密度随土层深度递减速度较慢,根系在下层土壤的分布相对增多。

It is found that before the pearlitic and upper-bainitic reactions, a pro-cutectoid orpro-bainitic phase is precipitated along the austenite grain boundaries in the cyanidedsamples; and it is thought that this is likely a nitrogen-bearing phase which provides thephase boundary effect for the nucleation of the reactions and impoverishes the parentaustenite in alloy content, thus accelerating the transformation of austenite.
实验中发现,在珠光体及上贝茵体形成之前,氰化试样中均有一种过剩相沿奥氏体晶粒边界析出。这种先析相可能是一种含氮的化合物,其析出为珠光体及上贝茵体的非自发形核提供了现成的有利界面,并使奥氏体合金化程度降低,因而加速了转变。
