- 摘要:
- 为降低东方百合索邦发生叶烧的概率,对鳞茎周长、鳞茎储存时间、易感病时期土壤平均温度与百合叶烧之间的关系进行了研究。结果表明:储存时间相同,鳞茎的周长越长,越易发生叶烧;鳞茎周长相同时,种球的储存时间越长,越易发生叶烧;在百合生长的关键时期,土壤温度长期偏低,尤其是长期低于12℃,易发生叶烧。
- Abstract:
- In order to reduce the ratio of leaf burn in Sorbonne,the relationship between size,storage time,soil temperature(susceptible to disease period)and leaf burn were studied.The results showed that under the same storage time,the longer circumference of bulb,the higher morbidity rate of leaf burn;While the longer storage time,the higher morbidity rate of leaf burn under the same circumference of bulb.When the soil temperature was low for a long time,especially lower than 12℃ during the very important period,the morbidity rate of leaf burn was higher.In addition,the prevention measures were put forward to provide reference for the control of leaf burn.
