作者于1990年6月——1992年6月对广西春、夏、秋大豆锈病进行广泛调查、并设立病圃系统观察结果表明:在广西各主产大豆县市中,几乎都有锈病发生,有时也相当严重。除已知7个县市外,本次新发现了32个县市亦有此病分布,并在观察圃冬大豆上观察到在自然条件下本病原菌所产生的冬孢子堆。结果还表明:在25个品种或育种材料中,桂豆2号、油84——87和全州小黄豆等较抗病。在广西,山区终年均可发生,平原则以秋冬豆较常见。但不论山区或平原,雨多比干旱重,近水源比远离水源重,间套种比纯种重。
The author conducted extensive surveys on the rust of soybean in spring, summer and autumn in Guangxi from June 1990 to June 1992 and set up systematic observation of nursery. The results showed that almost all the rust occurred in Guangxi’s main producing soybean counties and cities, Sometimes quite serious. In addition to the seven counties and cities that are known, the newly discovered 32 counties and cities also reported the distribution of this disease and observed the teliospores produced by this pathogen under natural conditions in the observation of winter winter soybean. The results also showed that among the 25 cultivars or breeding materials, Gui Dou No.2, No.88 - 87 and Quanzhou Small Soybean were more resistant to disease. In Guangxi, mountain can occur all year round, while the autumn is more common in plain. However, no matter in mountainous areas or plains, the rain is heavier than the dry, the water near the source is heavier than the water source, and the interplanting is heavier than the purebred.
