【Objective】The present experiment was carried out to find out a new cooling method for Venlo-type greenhouse in order to provide references for rational utilization of Venlo-type greenhouse. 【Method】The spray directions have been changed from roof of Venlo-type greenhouse to its sunshade net， and its effect on green house conditions such as temperature， illumination intensity and relative air humidity were studied. 【Result】Spraying on sunshade net of Venlo-type greenhouse has been proven quiet satisfactory in its cooling application. The internal temperature was found to be 4.6 degrees less than outside temperatures. The indoor temperatures were found to be in range of 34.4-37.4℃， when outside temperature was 41℃. The indoor illumination intensity was observed to ranged between 3000 and 16000 lx and decreased maximum by 86.8% compared to outdoor illumination intensity. The indoor relative air humidity ranged from 50-70% which was appropriate for growth of most horticultural crops. 【Conclusion】Spraying on the sunshade net was found conducive to cool the Venlo-type greenhouse in summer. This type of greenhouse was suitable for planting thermo-tolerant and shade-tolerant crops.
