夏季

So the present study was taken to compare the differences in the mechanisms of dissipating excess light energy in cucurbit crops and to study the differences in both the ROS metabolism in root system and the photosynthesis among six cucurbit crops with different temperature tolerance growing at different root-temperatures. The main results are as follows: 1、The species specific response of three cucurbit crops with different heat-tolerance: warm-adapted cucumber, heat-tolerant sponge gourd and heat-sensitive figleaf gourd to diurnal changes in air temperature and irradiance intensity were investigated in a typical summer sunny day. Three cucurbit species were compared using parameters in gas exchange, chlorophyll fluorenscence, photon allocation and photosynthetic electron flux.

因此，本试验以温度敏感性不同的瓜类作物为材料，研究了夏季自然条件下不同物种间在耗散过量光能的主要机制差异；探讨了它们对不同根际温度在根系活性氧代谢及地上部光合作用等方面的生理响应差异，所取得的主要结果如下： 1、在夏季晴天条件下，三种温度敏感性不同的瓜类作物：喜温的黄瓜，耐热性的丝瓜与热敏感的黑籽南瓜在气体交换、叶绿素荧光、光能分配及光合电子流对一天中温度与光照环境变化的响应上存在物种间差异和日变化特征。

Through the analysis on the history data, we find out the rule that precipitation how to effect on wheat yield in summer, and how to estimate the wheat yield trend of next year. It is important to direct the wheat production, and to promote the wheat yield.

通过对历史资料的分析，找出夏季降水对小麦产量影响的一般规律，进一步找出利用夏季降水的丰缺程度对翌年小麦产量趋势作出预测的方法，对于指导小麦生产趋利避害，巧用气候资源，合理组装小麦生产的配套技术，以及最大限度的利用自然降水资源，促进小麦单产大幅度提高，具有十分重要的意义。

The RegCM2 model is capable of well simulating regional distribution of anomalous precipitation in years of wetter and dryer summer that disclose the effects of different dynamic and thermal structures of the preceding spring, the results of which will provide scientific basis to some extent for short-term climate prediction in Northwest China.

The results indicated that the main turfgrass diseases were brown patch and Pythum diseases, and their pathogens were Rhizoctonia and Pythium respectively, of which the diseases of Poa pratensis,Lolium perenne and Agrostis were mainly caused by Rhizotonia, whereas the diseases of Festuca arundinaea was mainly caused by Pythium.
