Résumé partiel
In view of the shortage of rainfall in the semi-arid areas of Guanzhong,Shaanxi,the spatial and temporal distribution is seriously uneven,the main research object is the specific fruit-kiwifruit of Shaanxi Guanzhong.In the whole growth periods of kiwifruit trees,the research designs different irrigation treatments,which are based on the real-time dynamic change of soil water in kiwi garden.The research analyzes the affection of the different irrigation treatments on kiwifruit’s water need and consumption rule,physiological and ecological index,fruit quality index,yield, water use efficiency and economic benefit evaluation ; To study, and establishes the most suitable irrigation system of kiwifruit under drip irrigation,provide the theoretical basis for the cultivation of semi-arid area in Guanzhong area of Shaanxi province sustainable development type water saving, high quality and high yield of kiwifruit trees, stable and efficient. The main results of the study are as follows :(1) The soil temperature at different depths showed a maximum value, a minimum value and an average value. With the increase of soil depth, the change of soil temperature gradually decreases.The soil temperature at the same depth decreased with the increase of irrigation quota,the performance of the continuation of time as the first increase and then reduce the trend in the whole phenophase stage.With the increase of soil depth,soil temperature showed a tendency to changed from big to small, then back to big again. Temperature is the main factor affecting the soil temperature, but not the only factor affecting the soil temperature, other factors still need to be explored.
