不同施肥量对移栽橡胶草农艺性状及产量的影响

摘要

为研究不同施肥量对橡胶草农艺性状及产量的影响,确定伊犁河谷移栽橡胶草最佳施肥量,采用“3414”最优回归设计方法,对橡胶草氮磷钾肥料合理配施进行研究.结果表明,不同氮磷钾施用量对橡胶草农艺性状有不同影响,氮磷钾配合施用能明显提高橡胶草产量,在伊犁河谷移栽橡胶草适宜的N、P2O5和K2O施用量分别为155.25、207、90.20 kg/hm2.%In order to study the effects of different fertilizer rates on agronomic characters and yield of transplanting Taraxacum kok-saghyz and determine the optimal fertilizer rate in Ili Valley,the "3414" optimal regression design method was used to study the rational distribution of N,P and K for Taraxacum kok-saghyz.The results showed that different N,P and K application amounts had different effects on agronomic traits of Taraxacum kok-saghyz.The combined application of N,P and K could significantly improve the yield of Taraxacum kok-saghyz.In Ili Valley,the suitable N,P2O5 and K2O application amount for transplanting Taraxacum kok-saghyz was 155.25,207 and 90.20 kg/hm2 respectively.
