Abstract

The invention relates to a method for hibernating Indian red water lily, wherein it comprises that planting the Indian red water lily with 5-7 blades into storage pool, while the surface of bottom is covered with fine sand; pouring water into storage pool to be 45-55cm higher than the bottom soil; covering the storage pool with polyvinyl chloride film; then covering straw layer on the polyvinyl chloride film; in the day with enough light, it can increase the light intensity and temperature of water; when the temperature is higher than 18-20Deg. C in next spring, the stored Indian red water lily can be transplanted to exposed water. The invention has simple process and low cost.

Description

technical field [0001] The present invention relates to a method for artificially assisting plant overwintering, in particular to an artificially assisting method for overwintering Indian red water lilies; in particular, it relates to a method for keeping plant bulbs from freezing by means of winter water bodies and covering plastic films, so as to survive winter safely . Background technique [0002] The Indian red water lily (Nymphaea rubra) is native to central and southern India and is a tropical water lily. The leaves are nearly round and reddish brown. In the warm season, the flowers are purple-red; in the cold season, they are pink, and the anthers and stamens are red-orange.
