摘要1968年11月（春季）至1970年7月（隆冬），采用孢子诱捕法和牧草清洗法，对黑麦草-白三叶三叶草草地真菌孢子数量的季节变化进行了跟踪研究。定期计数五种寄生真菌和八种寄生真菌的孢子。在夏末和秋季数量最多，一般。类似于割过的和放牧过的地块。冠锈病（冠柄锈菌Corda）孢子的数量是最大的牧草生长速度下降到其最低的夏季水平时，其峰值之前的峰值约2周的腐殖真菌的孢子数。由此可见，被冠锈病杀死的黑麦草是牧草残体的重要组成部分。三叶草病原体在为腐殖酸提供基质方面的重要性不太明显。此外，还研究了苯菌灵对孢子数量的影响。根据预防绵羊面部湿疹病的建议，在牧场上喷洒杀菌剂。在...
Abstract Spore trapping and a herbage washing technique were used to follow seasonal changes of fungal spore numbers in ryegrass-white clover pasture from November (spring) 1968 to July (mid-winter) 1970. Spores of five parasitic fungi and of eight saprophytes were regularly counted. Numbers were highest in late summer and autumn, and were generally. similar in mown and grazed plots. Numbers of crown rust (Puccinia coronata Corda) spores were greatest when pasture growth rate had fallen to its lowest summer level, and their peak preceded the peak numbers of spores of saprophytic fungi by about 2 weeks. It is concluded that ryegrass killed by crown rust is an important component of the pasture debris on which the saprophytes grew. The importance of clover pathogens in providing substrate for the saprophytes is less obvious. In addition, the effects of benomyl on spore numbers were studied. The fungicide was sprayed on pasture according to recommendations for prevention of facial eczema disease of sheep. In...
