| 摘 要： | 采用田间系统调查、小区试验等方法对甘肃省张掖市娃娃菜干烧心病的流行规律和发病因子进行调查研究。结果表
明：张掖市娃娃菜干烧心病田间发病症状有3 种，即干边型、卷叶型和腐烂型；病叶集中出现在19～40 片叶之间；莲座期
开始发病，莲座期到包心期病害呈缓慢增长态势，结球期病害迅速增长，成熟期病情基本稳定；娃娃菜干烧心病的发生与植
株叶片Ca 含量、品种抗性、氮肥施用量、土壤全盐含量、茬口和种植密度等因子密切相关。

| Abstract: | This paper investigated and studied the epidemiological law and incidence factors of
tipburn of baby Chinese cabbage in Zhangye City，Gansu Province by field investigation and small pot
experiment．The results showed that there were 3 kinds of tipburn symptoms in fields，namely dry-type，leaf
rolling-type and rot-type．The sick leaves were concentrated in 19-40 leaves．The disease started on rosette
stage，developed slowly on heart covering stage，increased rapidly during balling period，and was basically
stable at maturity period．The occurrence of tipburn，Ca 2+ content，variety resistance，nitrogen fertilizer
application quantity，the soil total salt content，crops rotation characteristics and planting density，etc. fctors
were closely related． |
