Effects of magnesium zinc chelated foliar spraying on growth,yield and quality of Lilium Lanzhou
To investigate the effects of different concentrations of magnesium zinc chelated fertilizers on the growth,yield and quality of Lilium Lanzhou were examined.A single-factor randomized block design was used to determine the growth and index components of Lilium Lanzhou by spraying different concentrations of magnesium chelated fertilizer and zinc chelated fertilizer as foliar fertilizer.Spraying 800 times liquid zinc chelated(zinc concentration:0.181 mg·mL-1)fertilizer can increase the yield of Lilium Lanzhou,with the fresh yield of 5 523.10 kg • hm-2,and the dry yield of 2 330.90 kg·hm-2,which increase by 31.49％and 40.69％compared with the control,respectively.Spraying 800 times liquid magnesium chelated(magnesium concentration:0.069 mg·mL-1)fertilizer can promote the growth and development of Lilium Lanzhou,and significantly increase the content of index components.The plant height is 31.00 cm,the number of leaves is 157 pieces per plant and the total chlorophyll is 2.495 mg·g-1,which increase by 28.63％,9.79％,117.15％,compared with the control.The contents of Regaloside A,soluble polysaccharide and extract are increased by 22.08％,36.87％and 31.54％compared with the control,respectively.Magnesium chelated fertilizer and zinc chelated fertilizer can effectively promote the growth and development of Lilium Lanzhou,and increase production and quality.800 times liquid magnesium chelated fertilizer and 800 times liquid zinc chelated fertilizer are the optimum spraying concentration.
