钠复合肥提高移栽梭梭抗旱性

Sodium compound fertilizer improved drought tolerance of transplanted Haloxylon ammodendron

在阿拉善右旗干旱荒漠区,采用完全随机小区设计,以培育一年的梭梭为材料,探讨了施用钠复合肥对荒漠移栽梭梭生长及其抗旱性的影响.结果表明:与NP肥(与钠复合肥等量的N,P)相比,施用钠复合肥的梭梭成活率提高了59%,株高总增量提高了15%,冠幅总增量提高了600/0,主茎直径总增量提高了20%,主根直径总增量提高了14%,主根长提高了24%,茎分枝数提高了33%,整株干重提高了90%.以上结果反映出施用钠复合肥不仅能促进移栽梭梭生长,而且能提高其抗旱性.

A completely randomized plot experiment was conducted to study the effects of sodium compound fertilizer on the growth and drought tolerance of transplanted Haloxylon ammodendron in the desert region of Alxa Right Banner. Compared with NP fertilizer, Na compound fertilizer increased the survival percentage by 59%, total plant height increment by 15%, total crown diameter increment by 60%, total main stem diameter increment by 20%, main root diameter increment by 14%, main root length by 24%, stem branch quantities by 33%and dry weight by 90%. The above results suggested that Na compound fertilizer improved not only the plant growth but also its drought toerance.
