Through the photographic technology of fisheye lens and achieved the space image of cotton canopy structure distributing at different condition, and setupped cotton canopy structure base after image analysis. The experiment results indicated that the adaptability of different varieties to plant density is different, reasonable plant density is benefit to the raise of varieties product, and Xinluzao10 is better at high density（225000plant/ hm2） condition and Xinluzao12 is better at mid-high density（150000 plant / hm2） condition. For different nitrogen, Xinluzao10 is better at right nitrogen application amount（600 kg/ hm2） condition and Xinluzao12 is better at mid-high amount（900kg/ hm2）condition. For different irrigation, Xinluzao6 and Xinluzao12 is better at limited drip irrigation amount（1500 m3/ hm2） condition and Xinluzao8 Xinluzao13 is better at right drip irrigation amount（3000 m3/hm2） condition.

利用鱼眼镜头照相技术获取了不同处理棉花冠层分布空间图象，对图像进行处理分析，建立了棉花冠层图像库及分析诊断指标，研究结果表明，不同品种对种植密度适应性不同，合理的配置种植密度有利于品种的产量潜力的挖掘，高密（225000plant/ hm2）条件下选择新陆早10号、中高密（150000 plant / hm2）条件下选择新陆早12号栽培种植较为适宜；对于不同氮肥用量，适量氮肥用量（600 kg/ hm2）条件下选择新陆早10号、中高氮肥用量（900kg/ hm2）条件下选择新陆早12号较为适宜；对于不同灌水量，限量滴灌（1500 m3/ hm2）条件下选择新陆早6号、12号种植较适宜，适量滴灌（3000m3/hm2）条件下选择新陆早8号、13号种植较适宜。

If the low amount of larger than usual amount of usage and the peak is not large, the usual approach abroad is relatively small displacement of the compressor to obtain a larger displacement in parallel, with each increase用气量boot, so that not only Power is good, but also save energy.

如果低谷用量较大，而通常用量和高峰用量都不大，国外通常的办法是以较小排气量的空压机并联取得较大的排气量，随着用气量增大而逐一开机，这样不但对电网有好处，而且能节约能源。
