2013年和2014年,山东省济宁市金乡县连续两年出现大豆有荚无粒现象,严重影响了大豆产量。特别是2014年,有荚无粒现象相当普遍,有的地块甚至绝产。笔者通过对部分代表地块的深入调查,初步探索出大豆有荚无粒的发生和大豆病毒病、花期高温和水胁迫、种植密度及播期过早等密切相关,并同时提出选择抗逆性强品种、适时播种和适度浇水、合理密植等防治措施。
In 2013 and 2014, Jinxiang County, Jining City, Shandong Province, had pods without grain for two consecutive years, seriously affecting soybean production. Especially in 2014, it is quite common that there is no grain in the pods, and some plots are even absolutely dead. Through in-depth investigation of some representative plots, the author tentatively explored that there is a close correlation between occurrence of soybean pod without grain and soybean virus disease, high temperature and water stress in florescence, planting density and sowing date, and at the same time, Strong varieties, timely sowing and moderate watering, reasonable density and other control measures.
