The invention provides a method which is applied to direct
sowing and
seedling of yellow ginger seeds in large scale in a
greenhouse. The method comprises the following steps of place selection for anursery garden, pretreatment of seeds, uniform
sowing in
greenhouse surface after dividing the compartment, prophase management after
seedling emergence, middle-later period management after seedlingemergence,
transplanting after
seedling emergence, and the like, wherein three scientific
nutrient solution compounding are used in the management after seedling emergence and the
transplanting afterseedling emergence, thus providing reasonable
nutrition proportion for each growth stage of the seedling and ensuring various
nutrition elements required by the growth of the seedling. The method hasthe advantages of reducing the amount of
pesticide, easily and conveniently obtaining seedling, having high utilization ratio of
fertilizer, few broken roots, little
workload, quick growth after
transplanting with soil and capability of continuously breeding for more than 3 years by replacement of
seedbed substrate and treatment of soil, improving the using efficiency of the
greenhouse and reducing the production cost.
