Abstract:

The aim was to study the basic law of improving nutrition with fertilizer in Euonymus alatus (Thunb.) Sieb, and provide theoretical support of rational fertilization for Euonymus alatus (Thunb.) Sieb. Four-year-old Euonymus alatus (Thunb.) Sieb was used as materials, per plant fertilizer respectively was T1:10.00 g, T2:20.00 g, T3:30.00 g, T4: 40.00 g, T5: 50.00 g, one control and three replications, plot experiment design. The results showed that: T4 treatment always had the highest value of soluble protein content from May to August. T3 and T5 treatment followed after T4 treatment, when in the end of experiment three treatment soluble proteins increased by 74.75%, 53.54%, 62.63% than the control. T1 and T2 treatment had no significant difference with the control. T4 treatment had the lowest value of conductivity and T5 treatment was followed from June to August and lower than the control by 33.78%, 33.66%, T2 treatment reduce margin was the smallest, only 9.38%. Leaf chlorophyll content showed additional changes with the increased fertilizer from April to August, T4 and T5 treatment was increased by 26.61%, 29.03% than the control in August and significantly higher than T1-T3 treatment. T4 (40.00 g/plant) was the best treatment.
