摘要:

分析氮钾、氮磷钾、有机无机配合施肥对‘金叶’锦带生理特性的影响规律,以期为育苗和树木养护中科学合理施肥提供理论依据。试验在田间条件下,设置对照(T1)、常规施肥(T2)、氮磷钾处理(T3)、有机无机肥配合处理(T4)4个处理,3次重复。结果表明:6—9月T4可溶性糖含量较T3提高了28.54%、32.31%、24.92%、23.85%,T3显著高于对照;7—9月T4脯氨酸含量较T3提高了9.21%、11.99%、13.84%,T4显著高于T2,T3显著高于对照;6—9月T4 CAT活性分别较T2提高了41.58%、51.75%、55.69%、63.68%,T2与T3之间无显著差异;SOD活性T4分别较T3提高了8.97%、28.49%、30.19%、44.85%,T2与T3之间无显著差异,T2显著高于对照;7—9月,T4叶绿素含量分别较T3提高了13.00%、15.14%、22.33%,MDA含量降低了36.71%、43.17%、48.76%。综合分析认为,T4对改善‘金叶’锦带生理特性效果最显著。

Abstract:

The study aims to explore the effect of nitrogen-potassium, nitrogen-phosphorus-potassium, organic-inorganic fertilization on Weigela florida ‘Gold rush’ physiological characteristics, and to provide a basis for rational fertilization in growing seedlings and tree maintenance. The test was under field condition, treatments were set including control (T1), conventional fertilization (T2), nitrogen-phosphorus-potassium treatment (T3), organic-inorganic fertilizer treatment (T4), repeated 3 times. The results showed that: from June to September, the soluble sugar content of T4was higher than that of T3 by 28.54%, 32.31%, 24.92%, 23.85%, while the soluble sugar content of T3 was significantly higher than that of the control; the proline content of T4 was higher than that of T3 by 9.21%, 11.99%, 13.84%, and was significantly higher than that of T2, the proline content of T3 was significantly higher than that of control; the CAT activity of T4 was higher than that of T2 by 41.58%, 51.75%, 55.69%, 63.68%, there was no significant difference between T2 and T3; the SOD activity of T4 was higher than that of T3 by 8.97%, 28.49%, 30.19%, 44.85%, there was no significant difference between T2 and T3, and the SOD activity of T2 was significantly higher than that of the control; the chlorophyll content of T4 was higher than that of T3 by 13.00%, 15.14%, 22.33%, MDA content decreased by 36.71%, 43.17%, 48.76%. According to the comprehensive analysis, T4 has the most significant effect on improving physiological characteristics of Weigela florida ‘Gold rush’.
