Effect of irrigation quota on evapotranspiration ofthree cold-season turfgrass;

Based on the validated Penman-Monteith model,the evapotranspiration of Medicago sativa L.

Through field measurement in the Zhifanggou catchment of Ansai county,the evapotranspiration rule of apple orchard in the main growth period in a year (April to October) was analyzed.

Daily variation of transpiring water consumption of seedling of Ailanthus altissima under different drought stress;

Water capacity of branches and stems of Pinus tabulaeformis and its impact on transpiring water consumption.;

Five main conclusions were gotten as follows:(1)The transpiring water consumption of different seedlings in the day time presented a sustained descent with the drought stress,the descending extent of different seedlings was obviously different.

Results show that the daily course of sap flow is a single-peaked curve;that the velocity in clear days is higher than in cloudy days and under an overcast sky,and that the daily water consumption of Prunus cerasifera and Platanus hispanicq is higher than that of Acer truncatum.

Employing LI-6400 photosynthesis system(LI-COR,1995,USA),this paper studied the gas exchange,water consumption,and water use efficiency of Populus alba×berolinensis seedlings under different water supply.

Environmental responses of four urban tree species transpiration in northern China

Analysis of the Variation of Transpiration of Popular Euphratica and Its Response to Ecological Water Supply at the Lower Reaches of Tarim River

Through a field experiment conducted in the hinterland of the Gurbantonggut Desert,in this study,the dynamic water regime in the soil and its effects on the transpirations of 2～4-year-aged artificial mixed communities of Haloxylon ammodendron,spacing regularly at 2 m×1 m,are observed.
