根外追肥对胶东卫矛生长特性的影响

Effects of Foliage Dressing on Growth Characteristics of Euonymus Kiautschovicus

在田间条件下,研究了胶东卫矛生长特性的变化规律。结果表明:胶东卫矛株高生长在9月份达到最高值,P4处理比对照提高了84.03%,差异显著;P5低于P4处理4.96 cm,无显著差异。叶片含水量在8月份达到最高值,P4,P5分别比对照提高了13.98%,11.58%,差异显著;P2与对照之间无显著差异。叶片水势在8月份达到最高值,P4比对照提高了78.93%,差异显著;P5与P4之间无显著差异,P3显著高于对照。叶绿素含量在8月份达到最高值,P4比对照提高了59.77%,差异显著;P2与对照之间无显著差异。综合分析认为,P4处理效果最佳。

The change regulations of growth characteristics of Euonymus kiautschovicus were studied under field conditions.Result showed that the plant height reached its peak in September. P4 treatment was 84. 03% higher than that of the control and the difference between them was significant. P5 treatment was 4. 96 cm lower than that of P4 treatment and the difference between them was not significant. Leaf water content reached its peak in August. P4 treatment and P5 treatment were increased by 13. 98% and 11. 58% compared with the control respectively,and the difference between them was significant. The difference between P2 treatment and the control was not significant. Leaf water potential reached its highest value in August. P4 treatment was increased by 78. 93% compared with the control and the difference between them was significant. The difference between P5 treatment and P4 treatment was not significant. P3 treatment was significant higher than the control. The chlorophyll contents reached its highest value in August. P4 treatment was 59. 77% higher than the control and the difference between them was significant. There was no significant difference between the P2 treatment and the control. Comprehensive analysis showed that P4 treatment was the best.
