为了探讨土壤类型与酸碱度对紫杉生长发育的影响,选择沙壤土、旱田土、腐殖土、河沙和苔藓等5种土壤类型(沙壤土pH分别为4.5,5.0,5.5,6.0,6.5,7.0,7.5,8.5)进行盆栽试验.结果表明:不同类型土壤对紫杉生长影响不同,在腐殖质中高生长最好,新梢长度达16.9 cm;其次是沙壤土,新梢长度达14.5 cm;在腐殖土和沙壤土中栽培的紫杉总根长度较大,河沙与苔藓基质中侧根和白根数量多.盆土酸碱度影响紫杉生长,土壤pH在5.5~7.0时,树高生长量差异不大,新梢长度为12.6~13.3 cm;当土壤pH小于4.5或大于7.5时,高生长受到抑制;土壤pH在5.5~7.0时,总根长度和侧根数量最多.
為瞭探討土壤類型與痠堿度對紫杉生長髮育的影響,選擇沙壤土、旱田土、腐殖土、河沙和苔蘚等5種土壤類型(沙壤土pH分彆為4.5,5.0,5.5,6.0,6.5,7.0,7.5,8.5)進行盆栽試驗.結果錶明:不同類型土壤對紫杉生長影響不同,在腐殖質中高生長最好,新梢長度達16.9 cm;其次是沙壤土,新梢長度達14.5 cm;在腐殖土和沙壤土中栽培的紫杉總根長度較大,河沙與苔蘚基質中側根和白根數量多.盆土痠堿度影響紫杉生長,土壤pH在5.5~7.0時,樹高生長量差異不大,新梢長度為12.6~13.3 cm;噹土壤pH小于4.5或大于7.5時,高生長受到抑製;土壤pH在5.5~7.0時,總根長度和側根數量最多.

In order to evaluate effect of soil types and pH value on growth of of Taxus cuspidata, sandy soil, upland soil,humus soil,river sand and moss were selected to cultivate,pH value was adjusted to 4. 5,5. 0,5. 5, 6. 0,6. 5,7. 0,7. 5 and 8. 5 respectively. These results indicated that there were significant variations of yew growth in different soils. The height of yew seedlings which planted in humus soil and sandy soil were superior to that of other soils,whose growth yields were 16. 9 cm and 14. 5 cm respectively. The root length of seedlings which planted in humus soil and sandy soil were superior to that of other soils. The amount of lateral root and albino root of seedlings which planted in river sand and moss were greater than those of other soils. There were significant variations of yew growth in different pH values. The height yield was no significant variation when the soil pH value was from 5. 5 to 7. 0,whose growth yield was from 12. 6 to 13. 3 cm. Nevertheless,the height yield was restrained when the soil pH value was less than 4 . 5 or greater than 7 . 5 . The root length and lateral root number was maximum when the soil pH value was from 5 . 5 to 7 . 0 .
