Figleaf gourd and turban squash plants showed the highest dry weights, light-saturated rates of the CO_2 assimilation P_(Nsat and stomatal conductances at 14℃. Successively lower values for these measurements were observed at temperatures of 24℃and 34℃respectively.

上述六种温度敏感性不同的瓜类作物中，组Ⅰ在低根际温度下表现了最大的生物量、光饱和二氧化碳同化速率P_(Nsat与气孔导度，其次为中根际温度处理植株，以高根际温度处理植株表现最低。

Statistic analysis showed that soil temperature as the driving factor to the diurnal variation of soil respiration. Soil temperature and soil moisture were the dominant environmental factors affecting the seasonal variation of soil respiration and explained 87% of its variability. LAI and root biomass were positively related to soil respiration rate, indicating that biotic factors also affected the seasonal variation of soil respiration. However, soil properties such as soil organic content, total nitrogen content, and C/N ratio had poor correlations with soil respiration. Top-dressing nitrogen fertilizer increased soil respiration significantly.

统计分析表明：土壤温度是玉米生态系统土壤呼吸日变化的驱动因素；土壤温度和土壤水分是影响土壤呼吸季节变化的关键因素，二者可以解释玉米生长季土壤呼吸时间变异的87%；LAI和根系生物量与土壤呼吸速率呈正相关，说明生物因子对土壤呼吸季节变化也有影响；土壤有机质、全氮和碳氮比等土壤理化特性与土壤呼吸速率的关系较弱；玉米生长季追施氮肥明显促进土壤呼吸速率。

The results indicated that OC in crop root and stubble was available for balance of soil OC in plough horizon, but was not enough generally as only mineral fertilizers were supplied. With no fertilizer, the biomass and the amount of OC of crop root and stubble both decreased year after year.

试验结果还表明，根茬有饥碳对维持耕层土壤有机碳的平衡有相当大的贡献，但在单施化肥时大多不足以补充矿化消牦；在不施肥时，根茬生物量和有机碳量均逐年下降。

The sequential double levels of O_3 and CO_2 lead to latter and lighter visible foliar symptoms than the concurrent double levels of O_3 and CO_2. It had more obvious alleviation of CO_2 to the negative effect of O_3 on plant height, root nodule, biomass and yield than the concurrent treatment.

对于O_3和CO_2逐渐达到倍增的处理，其叶片受害症状出现要比O_3和CO_2持续倍增的处理的晚，程度也轻；在株高、根瘤数量及重量、生物量、产量方面CO_2的对O_3负效应的削弱作用要比O_3和CO_2持续倍增的处理更明显。
