龙胆草栽培及斑枯病的防治

Cultivation of Gentian and Control of Septoria gentianicola

采用室内控温控湿催芽法．将催完芽的龙胆草种子经悬浮液悬浮后、均匀喷撒于准备好的苗床上．使种子播后不用覆土，且能保证播种均匀和种子定位。根据龙胆草幼苗期的生态特性．可采用田间套种直播育苗、塑料大棚育苗、小棚育苗等育苗技术。同时对斑枯病的防治进行了论述。

In order to overcome the low tolerance of gentian in germination period. indoor pregermination under temperature-and moisture-controlled condition was conducted. The pregerminated gentian seeds were suspended in the solution of corn starch or methyl cellulose and then sprayed to prepared seedling bed. There is no need of soil sealing. and it also makes sowing uniformly and seed located stably. Gentian is a strong thermopholic. hydrophilic and weak light requiring plant in seedling period. Therefore. ecologically artificial methods of seedling growing, such as under crop sowing on filed. grooving in greenhouse or in small arch house. were. used. Septoria gentianicola. which is a severe disease to gentian. can be controlled by thiophanate0methyl and carbendazol on seedling and crop field.
