China's Vegetable, 24:61-65.), mainly at Yangtze-Huaihe River Valley and areas to the south's plantation (Ye Yuanying thereof, Deng .2007, the overall merit of Chinese celery germ plasm resource. China's Vegetable, supplementary issue: 21-25.), Water dropwort is the variety type that wherein can grow under ground moistening condition, the incubation of its new lines breaches Chinese celery and must grow (Wang Liping in paddy field, Deng .2014, organic vegetable--aquatic vegetable production technology regulation. the Changjiang river vegetables, 1:5-11.) restriction, belong to the important breakthrough of Chinese celery water-saving culture, be expected to plant in China.General plantation in the fall or transplant, normal growth under the condition that " can have water in moistening, the ditch in furrow face " in facility many batches are gathered, and (Jiang Xiezeng, waits .2006, GA ₃on the impact of Water dropwort yield and quality in winter. China's Vegetable, 12:23-24.), extend the supply phase of Chinese celery.Water dropwort alleviates the labour intensity of grower, but require still higher to irrigation, and about the unclear (Wang Yan of concrete soil water-containing figureofmerit of ground moistening, Deng .2007, Water dropwort leaflet and petiole Analysis of Nutritive Composition. China's Vegetable, 11:13-15.), and whether irrigation quantity needed for different lines there are differences that there is not been reported.

Summary of the invention
