对云南省海拔1100m～2450m地区于春、夏、冬三季播种的百合灰霉病发病指数、种球成球率及品质进行了比较,结果表明:露地春植百合品种Siberia、Toro,灰霉病发病指数明显高于大棚种植,最高达36.2%,种球成球率明显低于大棚种植,最低仅33%。露地夏植百合灰霉病发病指数普遍较低,最低仅1.0%,种球成球率最高达到75%。露地冬植百合未发生包括灰霉病在内的任何叶部病害,各试验点灰霉病发病指数为0,生长季月均温18.5℃的试验场成球率为78%,生长季月均温超过20℃的试验场成球率为17%、25%。夏植、冬植还可提高百合种球外观质量、保持种球内在品质。
The disease index, the rate of ball formation and the quality of bulblets were sown in the areas of 1100m ~ 2450m above sea level in spring, summer and winter in Yunnan Province. The results showed that Siberia, Toro, Botrytis cinerea The incidence index was significantly higher than greenhouse cultivation, up to 36.2%, ball formation rate was significantly lower than greenhouse cultivation, the lowest only 33%. The exposure index of Botrytis cinerea gray mold was generally low, the lowest was only 1.0%, and the highest rate of ball formation reached 75%. There were no leaf diseases including gray mold disease in the exposed winter lily plants. The index of gray mold disease incidence was 0 in each test point, and the balling rate in the experimental field with the average monthly temperature of 18.5 ℃ during the growing season was 78% The balling rate of the test field with the temperature over 20 ℃ is 17% and 25%. Summer planting, winter planting can also improve the appearance of lily bulbs quality, maintain the inherent quality of bulbs.
