【摘要】 通过对吐鲁番地区鄯善县火焰山山北地区主要气象要素年变化特征、28年树龄无核白葡萄年生长周期内生长发育特点、栽培葡萄生长发育有效积温变化特征和规律及试验点生产中所采用的传统灌溉制度和灌溉定额的调查研究,建立了试验地区有效积温与天数的相关模型,得到无核白葡萄发育进程中进入不同物候期所需要的有效积温参数,同时,通过对试验点传统灌溉模式下,成龄无核白葡萄灌水时间和灌水定额的调查分析,初步提出了该地区葡萄节水灌溉应注意的几个关键问题。更多还原

【Abstract】 According to the investigation on annual variations of meteorological element,annual growth and development characters of 20 - years - old Thompson Seedless,feature and rule of effective accumulated temperature within growth cycle,and traditional irrigation schedule and quota of the experimental site were investigated.The model of effective accumulated temperature with number of days was established and the required accumulated temperature of Thompson Seedless into various phenphases were obtained.Meanwhile,based on the investigation of irrigation time and irrigation quota of adult Thompsons Seedless under traditional irrigation mode,several key problems were pointed out on grape water - saving irrigation of local areas.更多还原
