中文摘要:为探讨DSSAT模型在不同年型冬小麦灌溉制度优化中的可行性,利用涟水县水利科学研究站1985—2015年冬小麦生育期降水资料排频适线,得到了降水量经验频率分别为25%、50%和75%对应的设计值,然后选取淮安站2001—2016年期间与3种经验频率对应降水量接近的年份作为代表年——2007—2008年(丰水年)、2006—2007年(平水年)、2011—2012年(枯水年)。通过生育阶段和灌溉次数的不同组合,拟订了15种灌溉制度(T1~T15),借助调参后的DSSAT模型对3种年型冬小麦灌溉制度进行了模拟。结果表明,经调试后DSSAT品种参数能够较为准确地反映作物的主要遗传特征。在统筹考虑产量、灌溉用水量和水分利用效率最优的情况下,2007—2008年(丰水年)、2006—2007年(平水年)、2011—2012年(枯水年)均宜选取灌溉制度T3。在BCC-CSM11气候模式下,考虑RCP45、RCP85两种情景,模拟了2030—2095年冬小麦水分产量效应,发现当初始土壤含水率为田间持水率的60%、80%时,T3、T6相对于雨养条件具有一定的优越性。

Abstract:In order to discuss the feasibility of DSSAT model in the optimization of irrigation schedule for winter wheat in different hydrological years, the corresponding design values of precipitation experience frequency of 25%, 50% and 75% were obtained by using the precipitation data of the growth period of winter wheat from 1985 to 2015 in Lianshui Water Conservancy Research Institute. After that the years from 2001 to 2016 in Huaian Station with close corresponding precipitation of three kinds of empirical frequencies were taken as the representative years, and that was 2007—2008 (wet year), 2006—2007 (normal year) and 2011—2012 (dry year). Fifteen irrigation schedules(T1~T15) were drawn up through different combinations of growth stages and irrigation times, and the irrigation schedules were simulated in three hydrological years by using the DSSAT model after the parameter estimation and verification. The results showed that after calibrated, the genetic coefficients of winter wheat could accurately reflect the main genetic characteristics. Considering the yield, irrigation water capacity and the water use efficiency of winter wheat as a whole, it was advisable to select the irrigation schedule T3 from 2007 to 2008 (wet year), from 2006 to 2007 (normal year), and from 2011 to 2012 (dry year). The schedule T3 was irrigated with 50mm in the regreening period. The irrigation time of wintering, regreening and jointing periods were on December 25, February 20 and March 30, respectively. Under BCC-CSM1.1 climate model, RCP45 and RCP85 were considered to simulate the water and yield effect of winter wheat in 2030—2095 years, and then it was found that when the initial soil moisture content was 60% and 80% of the field capacity, T3 and T6 both had certain feasibility compared with the rainfed conditions.

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.
