不同栽培模式对五年生鸡血藤生理生化指标的影响

Effects of Different Cultivating Models on Physiological and Biochemical Index of Five-year-old Spatholobus suberectus Dunn.

以鸡血藤为试材,研究了不同栽培(火龙果、荔枝)模式下,鸡血藤的存活率、株高、茎粗、一级分枝数等生长指标、生理指标和次生代谢产物的变化。结果表明:火龙果树下栽培的鸡血藤存活率、茎粗、一级分枝数明显高于荔枝树下栽培的鸡血藤;与荔枝树下栽培的鸡血藤相比,火龙果树下栽培的鸡血藤干物质积累量、可溶性蛋白质含量、可溶性糖含量、乙醇浸出物、总黄酮含量分别提高了33.13%、15.22%、25.65%、44.44%、21.07%,总灰分含量降低了14.03%。火龙果树下栽培的鸡血藤生长情况表现较好,且生理生化性状指标均高于荔枝树下栽培,更有利于鸡血藤的优质栽培。

Taking Spatholobus suberectus Dunn.as test material,the plant survival rate,plant height,main stem perimeter,primary shoot numbers,physiological and biochemical characteristics of Spatholobus suberectus Dunn.were researched by two kinds of cultivation models（pitaya and litchi）.The results indicated that the plant survival rate,plant height,main stem perimeter and primary shoot numbers under pitaya were significantly higher than litchi;compared with cultivation models under litchi,the plant dry matter accumulation,soluble protein content,soluble sugar content,ethanol extractum and total flavonoids under pitaya were respectively improved 33.13%,15.22%,25.65%,44.44%,21.07%,and the total ash content decreased by 14.03%.Spatholobus suberectus Dunn.grew better under pitaya,and the physiological and biochemical properties evaluation of Spatholobus suberectus Dunn.under pitaya was significantly higher than litchi,which was more beneficial to quality cultivation of Spatholobus suberectus Dunn.
