Effects of Different Fertilization Treatments on Physiological Characteristics of Weigela florida ‘Gold rush’
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’.

以三年生红叶李为试材,通过不同施入量的硫酸钾处理.取样测定叶片中的花青素、叶绿素含量以及叶片光合作用日变化.结果表明,与0g/丛及300g/丛处理相比较,施钾10g/丛能显著地提高中午12:00的叶片净光合速率;2种施钾处理的叶片净光合速率日均值均显著高于0g/丛.施钾处理的气孔导度在中午12:00无低谷,而0g/丛12:00为低谷,适量施用钾肥能够显著提高红叶李叶片在高温时段(12:00)的净光合速率及日净光合速率,改善叶片的气孔导度.施钾不能显著提高叶片的花青素和叶绿素含量,即对增进红叶植物叶片色泽无显著作用.

在盆栽条件下研究了水分亏缺时,氮、磷营养对春小麦幼苗渗透物质及相关保护酶活性的影响.结果表明:水分胁迫使春小麦幼苗叶片游离脯氨酸、可溶性糖含量增加,RWC降低,POD、CAT活性增强.随着水分亏缺加剧,氮营养相应地提高了幼苗叶片脯氨酸、可溶性糖含量以及POD、CAT活性;磷营养仅能提高叶片脯氨酸含量以及POD活性,但使其可溶性糖含量以及CAT活性维持在较低水平上.施肥使叶片RWC降低.春小麦的抗逆性指标之间存在相关性,特别是小麦幼苗叶片POD活性与游离脯氨酸累积量之间有极显著正相关关系,其决定系数r2为0.747 2. 图1 表2 参12

紫叶矮樱(Pruns×cistena cv.pissardii)在炎热的夏季,叶片颜色会由紫红色变为绿色,降低了紫叶矮樱的观赏效果.本研究进行了叶面喷施不同浓度的磷钾营养元素来降低紫叶矮樱叶片叶绿素含量试验,结果表明,喷施磷元素的紫叶矮樱叶绿素含量均比对照高,其净光合速率也比对照强,但差异不显著;而钾元素极显著的降低叶片中叶绿素含量,光合速率降低,磷钾元素共同作用效果与钾相似;喷施磷钾元素的紫叶矮樱花色素苷含量均比对照高,与对照相比差异极显著,净光合速率明显降低.
