【目的】掌握越南玉米产业发展历程及现状,为中越两国开展科技合作提供决策参考。【方法】基于越南统计局数据,总结归纳越南玉米发展历程、种植生产、进口贸易及各生态区生产情况,对中越玉米在技术和市场等方面的合作进行展望。【结果】越南从事玉米育种研究较晚,品种引入,国外品种引进对越南玉米育种和生产发展起重要作用,越南玉米种植面积、单产和总产量自20世纪80年代以来逐年上升,目前种植面积在100万ha左右,总产量在500万t左右,2014年以来呈现逐年下滑趋势。从生态区域来看种植主要集中在北部丘陵山区,2019年北部种植面积61.97万ha,占全越南玉米1/3以上;从省份来看种植面积较大省份有山罗省、多乐省、义安省和清化省,产量来较大省份是多乐省、山罗省、同奈省、清化省、义安省、嘉莱省和得农省;从南北区域来看种植面积和产量主要集中在北部;从栽培条件来看,东南部、九龙江平原和西原地区玉米单产最高,单产较高省份是同塔、坚江、安江和同奈。越南生产的玉米约60%用于食用和生产酒精,40%用于生产饲料。越南生产的玉米满足不了本国需求,需从美国、印度等国进口大量玉米,年进口量100万~180万t,且80%为转基因玉米。种植品种主要有单交玉米GS9989(A380)、VN5885、TC 14-1,鲜食糯玉米品种VN556、甜玉米品种20(DL20)青料饲料两用玉米VS71品种。玉米草地贪夜蛾是危害中越两国迁飞性害虫;同时越南玉米生产中存在品种单一、优良品种匮乏、栽培技术落后制约其玉米产业的发展。【建议】我国相关机构部门应加强与越南玉米研究所和越南农业大学等农业研究部门合作;加大示范推广我国优良玉米品种;在越南登记经示范适用玉米品种;与企业合作将适宜品种出口到越南,加强与东盟国家合作。

Saline intrusion is a hot issue and has always been of concern in the VMD(Vietnamese Mekong Delta),especially in the context of many changes of impact factors such as upstream flows and SLR(Sea Levels Rise).Vulnerability to changes in the upstream flows and SLR ismust-have reasons for updated and interpreted *** information is used for exploiting of soil and water *** 11 model was successfully applied to assess the saline *** study provided the picture of the saline intrusion in the dry season from January to May in the VMD in the existing situation(2015 and 2016)and the future(2030 and 2050)under the impact of flow at Kratie in various frequencies of 18%,50%and 85%based on the time series of 2001-2016,and SLR according to RCP(Representative Concentration Pathway)4.5 scenario of MONRE(Ministry of Natural Resources and Environment)of Vietnam issued in *** results show that in the year 2015 the ASI(Saline Intrusion Area)in the VMD was relatively low due to moderate tidal level and high Kratie discharge(P=18%).The scenario like the situation in 2016 and in the future ASI increased significantly compared to the 2015 baseline scenario which shows that the VMD is very vulnerable to saline *** on multivariate regression analysis,the study also presented the formulas for the relationship between the ASI of 0.25 g/L,2.5 g/L and 4.0 g/L thresholds and the impact factors such as the average discharge at Kratie and the maximum daily tidal level in East Coast during the dry season from January to *** an adjusted R2 at 0.913-0.974,these formulas are believed to be reliable for predicting ASIs based on the Kratie flow and the East Coast tidal level.
