Integrated Evaluation on Cold Resistance of Container Phoebe hui Seedlings by Different Fertilization Treatments

  • 摘要: 以同一种源的细叶楠(Phoebe hui)容器苗为试验材料,对其进行NPK4种不同配比施肥(N:P:K = 1:1:1、2:1:1、1:2:1和1:1:2)和3种叶面施肥(0、0.3%硼酸钠和5 mmol/L水杨酸)12种处理,研究其对细叶楠容器苗高生长、耐寒性生理指标和田间耐寒力的影响。结果表明:NPK比例为1:1:1和1:2:1的各自3个处理间,叶面施肥的苗高显著低于不施肥;在所有12个处理中,NPK比例为1:1:1、2:1:1和1:2:1且叶面不施肥的3个处理的苗高与其他处理间的差异达显著性水平。超氧化物歧化酶(SOD)、过氧化物酶(POD)性和丙二醛(MDA)含量在不同施肥处理间表现出一定的差异,脯氨酸(Pro)、可溶性糖(SS)和可溶性蛋白(SP)含量在NPK 4种比例的各自3个处理间的差异均达到了显著性水平。NPK比例保持不变时,叶面不施肥处理的隶属度显著低于叶面施肥处理,但田间耐寒力指标的差异不显著。本研究表明,N:P:K = 1:1:2且叶面喷施5 mmol/L水杨酸的处理为细叶楠容器苗最佳的施肥方式,其容器苗的田间耐寒力最优、苗高生长较高。
    Abstract: Experiments were conducted on container seedling of Phoebe hui from the same provenance treated with four different ratio of N, P and K, and with two different foliage fertilizer to study influence of different treatment on height growth, cold resistance indicators and field cold hardiness of seedlings. The result showed that height growth of seedlings treated with N:P:K ratio of 1:1:1 and 1:2:1, and with foliar fertilizer was significantly lower than that without foliar fertilizer. Height growth of seedlings treated with N:P:K ratio of 1:1:1, 2:1:1 and 1:2:1, and without foliar fertilizer had significant difference with the other 9 treatments. SOD, POD activity and MDA content varied among fertilization treatments. There were significant differences among three treatments of four N:P:K ratios in Pro, SS and SP contents. The average membership grade with no foliar fertilization was significantly lower than that with foliar fertilization with the same N:P:K ratio, but cold hardiness index was not significantly different. Integrated evaluation resulted that seedlings treated by N:P:K ratio 1:1:2 and foliar spraying of 5 mmol/L salicylic acid had the optimal cold hardiness and higher seedling height.
