In order to explore effect of BGA,a new organic drought resistant agent made from garbage,on traits of growth and water consuming of Euonymus japnicus under different daylight illumination and temperature,the tests in and out greenhouse were done at experiment base of China agricultural university.The results were as follows: biomass and water consuming intensity of Euonymus japnicus that was planted out greenhouse were larger than that in greenhouse whether BGA was used or not.The biomass of Euonymus japnicus got increased when BGA was added more,and the water consuming intensity was increased first,then decreased out greenhouse.The biomass of Euonymus japnicus was increased first,then decreased with increase of BGA dosage,and the water consuming intensity was increased all the while in greenhouse.WUE of Euonymus japnicus that was planted in greenhouse was nearly same as that out greenhouse when BGA was not added.The WUE of Euonymus japnicus that was planted out greenhouse was more than that in greenhouse after BGA was added.
