ResultThe results showed tat the sweet sorghum growth obviously surpassed the grain sorghum. The sugar content accumulation beginning and the total content were higher than the grain sorghum, but the sweet sorghum and the grain sorghum sugar accumulation general trend was consistent. Sweet sorghum biology yield was superiority, but grain sorghum ear of characteristic was superiority. In the physiological character, the chlorophyll content grain sorghum surpassed the sweet sorghum, but sweet sorghum was higher in the breath speed.

结果结果表明，甜高粱生长优势显著优于粒用高粱，主要表现在与生物产量有关的性状；糖含量的积累起点及总含量均高于粒用高粱，而甜高粱和粒用高粱糖积累总趋势是一致的；甜高粱生物产量优势强，而粒用高粱穗部性状优势强；生理性状中叶绿素含量粒用高粱优于甜高粱，而呼吸速率甜高粱偏高。

Determination of photosynthetic pigments used 80% of acetone extraction method directly and the photosynthetic characteristics of using Li-6400 portable photosynthesis detector. Results showed that Returning the right amount maize straw stem into field was able to significantly restraint this year winter wheat flag leaf Chla degradation, to raise the flag leaf Chla/Chlb in the watery metaphase and late stage, to effectively restraint the photosynthesis rate decrease in the watery stage, to increase the pertinence of photosynthesis rate and pigment compared to others. However returning more maize straw stem into field was able to accelerate the retrogradation of chlorophyll and photosynthesis rate decrease then the yield declined.

结果表明：适量的玉米秸秆还田(9 000 kg/hm^2)可显著抑制接茬冬小麦灌浆中后期旗叶Chla降解，提高小麦灌浆中后期旗叶Chla/Chlb的比值，有效抑制灌浆期旗叶光合速率的下降，与其他处理相比，其光合速率与叶绿素的相关性得到加强；过量的秸秆还田(15 000 kg/hm^2)，加速了光合色素的降解，使得光合速率下降，产量降低；在各处理中，处理Ⅱ(9 000 kg/hm^2)产量最高。

4 Mechanisms of the effects on yield and quality With the application of nitrogen, the chlorophyll content, NRase activity, photosynthesis rate, fluorescence parameters in the ear leaves of spring-sown maize and summer-sown maize were affected dramatically, which could affect the yield and quality of maize.

3.4 不同施氮水平产量和品质差异的生理学基础春夏玉米套作时，施氮处理显著影响春、夏玉米穗位叶叶绿素含量、硝酸还原酶活性、光合速率、荧光参数等，从而影响产量和品质。

When the nitrogen was 120 N kg/hm2,the chlorophyll content of flag leaf was the most highest,the speed of flag leaf aging was slow,the extent of declining metabolizability was slow too.

活性氧对植物细胞的伤害是多方位不同层次水平上的全面伤害，是植物体诱发衰老的主要内因[2-5]，许多试验结果表明，叶片

The results showed that compared with flat planting,the leaf area, flag leaf function duration, chlorophyll content and the activities of protection enzymes of SOD, POD and CAT in leaves in straw mulching were significantly higher, its malondialdehyde content and over oxidation degree of membrane lipids was lower, the speed of flag leaf aging was slower and the metabolizability was vigorous, which are beneficial to the grain-filling and accumulation of photosynthesis products.

结果表明，覆草栽培叶面积、旗叶功能期、叶绿素含量、叶片保护酶活性(SOD、POD、CAT)显著高于常规栽培，膜脂过氧化程度较低，叶片衰老速度缓慢，代谢强度旺盛，有利于籽粒灌浆和光合产物的积累。

The treatments of NPK and NPK+BCF were better than those of N, NP, NK on the plant height, stem, leaves area, chlorophyll, bearing fruit stick, extent of unfolding, the time of blooming and bearing fruit, and plant soma changes of harvest time. The ratio of basal manure to after manuring and the different ratio of after manuring showed mutual effects: The excessive nutrient had unfavorable influences on plant growth and development in former time.

NPK+BCF及NPK的配方在株高、茎粗、叶面积、叶绿素含量、结果枝、展开度、开花期和挂果期、收获期植株营养体变化等指标上都优于NP、NK及只施N肥的配方；不同基追肥比例及不同追肥比例表现出共同的效果：前期施入过多的养分不利于茄子植株的生长发育。

After seedling trees of Yunhe Snow Pear were polluted by Pb(superscript 2+), Cd(superscript 2+), synthesis of chlorophyll was restrained, toxic effect of Pb(superscript 2+), Cd(superscript 2+) on seedling trees was intensified, membrane lipid peroxidation damage was increased. And the protective enzymes system start-up of polluted seedling trees enhanced antioxidative enzymes activities of seedling trees.
