The small vegetable seedlings that have a similar flavor to toon are called toon seedlings.

Toon seedlings are seedling buds sprouted from the seeds of the toon tree. Due to seasonal restrictions, it is not easy for people to eat fresh parsnips in summer, fall and winter, so people put parsnip tree seeds in a warm and humid environment to make them germinate naturally, thus becoming parsnip seedlings.

Environmental conditions

Temperature and moisture are the environmental factors necessary for the growth of toon seed buds. Seed bud growth temperature is 15 ~ 25 ℃, winter, early spring is suitable for daylight greenhouse, kiln cellar, house production; late fall can be used to improve the sun beds, plastic greenhouses and other cultivation.

When the outside temperature is higher than 18 ℃, you can open-air production, but pay attention to the shade, avoid direct light irradiation, in order to prevent the reduction of quality.

Specific protection facilities should be adapted to local conditions, make full use of the idle facilities of the farm yard, appropriate transformation, to be applied. You should first meet the temperature requirements; secondly, to regulate the appropriate air humidity.
