Effects of Foliage Fertilization on Plant Growth and Bulb Yield of Lilium davidii var.unicolor

In semiarid hilly cropland area,the effects of physiological characteristics and yield of Lilium davidii var.unicolor were studied by spraying four kinds of new foliage fertilizers during early squaring period,squaring period and flowering period.The results showed that it could significantly increase plant height,stem diameter,the number of leaves,leaf color,wilting stage and bulb yield of L.davidii var.unicolor by foliar spraying high potassium nutrients,FA Handilong,Huaduoduo and potassium dihydrogen phosphate in growing season.It showed that the four kinds of fertilizer could promote the growth and development of Lily,delay wilting stage,significantly increase the lily yield and net income,thus it can promote in the production of L.davidii var.unicolor.
