As compared with the traditional irrigation-traditional fertilization, the following results of the improved optimized irrigation-optimized fertilization were obtained: significantly higher nitrogen use efficiency; the like tiller number per unit area, percentage of the tiller ear number/the tiller number, the ear number per unit area, the greatly reduced grain number per ear, and significantly heavier weight of 1, 000 grains; a trifle taller plants; shorter base internode length, a bit more weight per unit internode length, longer internode length under ear; almost the same 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; a little longer flag leaf, 2〓 leaf, 3〓 leaf (but the three leaves were shorter than those of the optimized irrigation-traditional fertilization) and shorter 4〓 leaf from top, a bit reduced total area of these leaves; almost the same leaf thickness, mean canopy leaf tilt angle, light extinction coefficient , ratio of light penetration in the upper, middle and lower parts of the wheat canopy, and fair plant type; almost the same senescence process of flag leaf; and increased root amount in 0-120cm soil layer and smaller rate of progressive decrease of the root length density and root weight density with soil getting deep, which can strengthen the resistance to adverse conditions such as water stress in the later stage.

在优化水肥条件下，冬小麦总分蘖数、成穗率及单位面积穗数与传统水肥比较接近，但穗粒数显著减少，千粒重显著提高；株高稍有增加；基部节间长度缩短，充实度略微增高，穗下节间增长；中后期LAI与传统水肥的LAI值基本吻合；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，但抽穗至成熟所形成的干物质量增加；上三叶变长（但上三叶长度增加幅度小于优化灌溉-传统施肥处理），倒4叶变短，总叶面积略有减少；叶片厚度、冠层平均叶倾角、消光系数、冠层各层的透光率与传统水肥差异很小，株型较好；旗叶叶绿素含量动态变化与传统水肥十分接近；0-120cm土层的总根量明显增加，上层根群和深层根群的差异最小，有利于提高小麦后期的抗逆力。

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。

The result indicates that there are two negative effect stages of temperature on rice and rice yield before tasseling and after tasseling. And the temperature effect is most obvious on seed-setting rate, secondly on 1000-grain weight and thirdly on yield. The effect of minimum temperature on rice is greater than that of maximum temperature.

结果表明，气温对水稻产量构成和产量在始穗前和始穗后各有一个负影响时段，其影响程度始穗前大于始穗后；对结实率影响最大，其次是千粒重，再次是产量；最低气温的影响大于最高气温。

So the little impudent fellow would waste many an ear in a forenoon; till at last, seizing some longer and plumper one,considerably bigger than himself, and skilfully balancing it, he would set out with it to the woods, like a tiger with a buffalo, by the same zig-zag course and frequent pauses, scratching along with it as if it were too heavy for him and falling all the while, making its fall a diagonal between a perpendicular and horizontal, being determined to put it through at any rate;—— a singularly frivolous and whimsical fellow;—— and so he would get off with it to where he lived, perhaps carry it to the top of a pine tree forty or fifty rods distant, and I would afterwards find the cobs strewn about the woods in various directions.

就是这样，这个唐突的家伙一个上午就糟蹋了好些玉米穗；直到最后，它攫起了最长最大的一支，比它自己还大得多，很灵巧地背了就走，回森林去，好像一只老虎背了一只水牛，却还是弯弯曲曲地走，走走又停停，辛辛苦苦前进，好像那玉米穗太重，老是掉落，它让王米穗处在介乎垂直线与地平线之间的对角线状态，决心要把它拿到目的地去；——一个少见的这样轻桃而三心二意的家伙；——这样它把玉米穗带到它住的地方，也许是四五十杆之外的一棵松树的顶上去了，事后我总可以看见，那穗轴被乱掷在森林各处。

The characteristic of anthocyanin accumulation and related factors on anthocyanin synthesis of three currant varieties fruits were analysed. The results were as follow:Great quantities of anthocyanin were accumulaed in black and red currant fruits during the late stage of development, but white currant fruits synthetized anthocyanin during the early period of development.

以三种穗醋栗为试材，对果实中花青苷积累及其相关因素进行了分析，研究结果如下：黑穗醋栗和红穗醋栗在果实发育后期大量积累花青苷，而白穗醋栗仅在果实发育初期合成花青苷。

The result of rooting experiment in the phytotron indicated that 25/20℃ resulted in more roots and 30/25℃ resulted in longer roots with higher dry weight.

在变叶木插穗的取穗标准试验中，试验结果显示，取穗时应取枝条上部位且较长，至少带有4片叶的插穗。

The difference in yield, its components, basic characteristics such as mean size and bare tip length of cobs, plant height, base internode diameter, secondary root number per plant, LAI and DMW at the same measuring date, between the three treatments were insignificant respectively; the optimized fertilization made the three leaves around corn cob rather smaller, the cob leaf slightly thinner, a decrease of the cob leaf chlorophyll content at greater rate at the later stage, and dry matter accumulation amount slightly reduced from flowering to grain filling.

在优化施肥、秸秆还田优化施肥及传统施肥条件下，夏玉米穗长、穗粗、秃顶长、株高、基部伸长节间粗度、单株各层次生根条数、同一时期的叶面积指数和干物质积累量无显著性差异。在优化施肥条件下，夏玉米棒三叶总叶面积略微减少，穗位叶叶片略微变薄，生育后期穗位叶叶绿素含量下降稍快，吐丝-收获的干物质积累量略有下降。

No matter mono-cropping and relay-planting, the increase of nitrogen use could improve the SPS activity of spring-sown maize and high oil summer-sown maize at the stage of 20 DAA, but decrease those of normal summer-sown maize.

无论单作还是套作，增施氮肥使春玉米穗位叶花后20天的SPS活性增强，但套作时高氮却使穗位叶SPS略有下降；增施氮肥使普通夏玉米穗位叶SPS活性下降，高油夏玉米穗位叶SPS活性增加。
