干旱及复水对油茶土壤养分及微生物的影响
Effects of drought and re-water on nutrients and microorganisms in Camellia oleifera soil
[目的]为探究土壤不同干旱程度对根际土壤养分与微生物的影响,指导油茶科学灌水。[方法]采用棚内盆栽试验,对 3 年生'华金'进行不同土壤体积含水量处理(5%～10、10%～15%、15%～20%、20%～25%),处理 30 天后均复水到体积含水量 20%～25%,测定油茶生长量、土壤养分含量和土壤微生物多样性。[结果]1)试验表明当土壤体积含水量降至较低水平(5%～15%)时,会导致油茶植株生长变缓。2)不同处理下根际土壤土壤水分含量(SM)与…查看全部>>
[Objective]To investigate the effects of different levels of soil drought on the growth of Camellia oleifera and the nutrient content and microbial community in the rhizosphere soil,provide guidance for scientific irrigation practices for Camellia oleifera.[Methods]A greenhouse pot experiment was conducted on 3-year-old'Huajin'plants,subjected to different soil volumetric water content treatments(5%-10%,10%-15%,15%-20%,20%-25%).After 30 days of treatment,all…查看全部>>
