Sowing time of wheat in south eastern Australia varies from autumn to early winter, depending on the seasonal 'break'. Wheat yields are often reduced by frost damage at flowering time and by heat-and/or water-stress during grain filling. Selecting suitable varieties for specific sowing times is a complex decision farmers make because these varietal phenology and climate risks have to be assessed together. In order to help farmers make decisions, they need tools that simulate and analyse agronomically-suitable sowing dates (ASSD) for a given variety of wheat. The hypothesis underlining this study is the integration of a wheat phenology model with historical climate data is an effective approach to modelling the ASSD of current varieties used in the wheat growing areas of Southern NSW. The parameters of the wheat phenology model were based on data from five years of field experimentation across 15 sites. Data from four sites were used to examine varietal suitability in relation to sowing time and its associated risks of frost and heat damage. The optimum ASSD for any variety at 72 locations across Southern NSW was investigated. The results showed that there were substantial spatial variations in the ASSD across the target region. ASSD for a late maturing wheat genotype (EGA Gregory) can range from early March to late April, while the earliest acceptable sowing date for an early maturing spring wheat genotype (H46) can range from early to late May. The wide range of spatial variation in the earliest and latest sowing dates, as well as the varied length of sowing opportunities, highlighted the importance of being able to apply a modelling approach which can integrate information on crop phenology with climate risk for a given location. This approach would allow better decision-making on suitable varieties and sowing dates in order to minimise the risk of frost and heat damage affecting crop yield. 相似文献

澳大利亚昆士兰大学经研究获得抗香蕉枯萎病的基因改良植株。将抗香蕉巴拿马病害(即香蕉枯萎病)的单个基因插入香蕉基因组中,该基因能阻止香蕉细胞在受到病菌攻击后凋亡。该研究将给非洲贫困国家的香蕉种植业带去希望。但在澳大利亚本土,蕉农却反对将基因改良香蕉商业化。香蕉枯萎病已经导致澳大利亚北部地区香蕉业瘫痪,一旦传至昆士兰和新南威尔士等地区,将会产生同样的后果。该病害可通过土壤和水传播。 相似文献

赴澳大利亚 新西兰防火考察观感 总被引:1,自引:0,他引:1
为提高全区森林草原防火的科学化水平,学习和借鉴澳大利亚、新西兰森林草原防火的做法与经验,2007年10月22日—11月6日,应澳大利亚新南威尔士州乡村消防局和新西兰中国贸易促进委员会的邀请,自治区林业厅组织部分盟市林业局长、防火办主任组成防火考察团,对澳大利亚和新西兰的森林草原防火情况进行了考察。期间,代表团走访了澳、新两国的部分重点防火区域,并与有关部门进行了座谈交流,基本了解了这两个国家防火特点、运作程序和管理方法,并与自治区的森林草原防火现状比较,形成了以下观感,供参考。 相似文献
