中文摘要:基于云南省滇中地区4个国家气象站点逐日气象资料和烤烟不同生育期作物系数,根据FAO 56推荐的Penman—Monteith公式和单作物系数法,计算了滇中地区近58a(1956—2013年)参考作物蒸发蒸腾量、烤烟净灌溉需水量及净灌溉需求指数,分析了滇中地区烤烟生育期净灌溉需水变异特征;利用GIS普通克里金法,对滇中地区烤烟需水量、净灌溉需水量和净灌溉需求指数进行空间分布分析;采用通径分析法研究灌溉需求指数变化成因。研究结果表明,滇中地区烤烟净灌溉需求指数随生育期变化逐渐减少,即伸根期、旺长期、成熟期;其中,净灌溉需求指数大于零的年数占54%,表明烤烟区在平水年条件下需人工灌溉补给;影响净灌溉需水量最主要的气象因子为降水量。

Abstract:Spatio-temporal variation of crop water requirement and net irrigation requirement can provide theoretical basis for irrigation scheduling in different areas. The research was based on ground meteorological data from four national meteorological sites and crop coefficient at different growth stages of tobacco in the middle of Yunnan Province. The reference crop evapotranspiration, net irrigation requirement and net irrigation requirement index in the middle of Yunnan Province within 58 years (1956—2013) were calculated using the Penman—Monteith equation recommended by Food and Agriculture Organization in 1998. The water demand variation characteristics of tobacco during the growing season were analyzed. The spatial analysis of water demand, net irrigation requirement and net irrigation requirement index of tobacco was done by using the ordinary Kringing method of GIS. The results showed that as the change of tobacco’s growing season, its net irrigation requirement index was gradually decreased. And the years with net irrigation requirement index which was larger than zero could be accounted for about 54% in the middle of Yunnan Province. It was indicated that tobacco needed artificial irrigation in normal years. The most positive and negative correlation factors for net irrigation requirement of tobacco was precipitation. Besides, the reference crop evapotranspiration, net irrigation requirement and net irrigation requirement index increased with latitude in the middle of Yunnan Province.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
