摘要：

为了确定追肥对改善卫矛营养的基本规律，为卫矛的合理施肥提供理论支持，以4年生卫矛为试材，单株施肥量分别为T1：10.00 g，T2：20.00 g，T3：30.00 g，T4：40.00 g，T5：50.00 g，1个对照，3次重复，小区试验设计。试验结果表明：5—8月T4处理可溶性蛋白含量始终处于最高值，T3、T5处理仅次于T4处理，试验末期分别比对照提高了74.75%、53.54%、62.63%，T1、T2处理与对照间无显著差异。6—8月T4处理电导率处于最低值，T5处理次之，8月份分别比对照降低了33.78%、33.66%，T2处理降低幅度最小，仅为9.38%；4—8月叶片内叶绿素含量随着施肥量增加表现出增加的变化，8月份T4、T5处理分别比对照提高26.61%、29.03%，显著高于T1~T3处理。综合分析认为，T4（40.00 g/株）施肥量为最佳处理。

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.
