摘    要:采用“3414”完全随机区组设计.开展热研4号王草的三要素平衡施肥田间试验.研究施肥对热研4号王草产量的影响。结果表明:施肥对热研4号王草产量有极显著的增产效应,氮、磷、钾肥增产的主次顺序为P〉K〉N;热研4号王草最高产量的氮、磷、钾优化施肥组合为尿素399.08kg/hm^2,钙镁磷肥224.40kg/hm^2,氯化钾60.38kg/hm^2,此时最高产量为385.0t/hm^2,其最佳施肥配比为形(N):W(P2O5):W(K2O):5.07:1.12:1;热研4号王草最佳施肥利润的氮、磷、钾优化施肥组合为尿素413.1kg/hm^2,钙镁磷肥207.9kg/hm^2,氯化钾156.1kg/hm^2,其最佳施肥利润达5634元/hm^2,此时产量为384.90t/hm^2,三要素配比为形(N):W(P2O5):W(K2O)=6.33:1.25:1。

关 键 词:热研4号王草  平衡施肥  数学模型

Abstract:Field trials for balanced application of fertilizer to Pennisetum purpureum Sehumacher. x P. glaucum (Linnaeus) R. Brown cv. Reyan No.4 were carried out by using the 3414 completely random block design to observe cv. Reyan No.4 yield and quality. The results showed fertilization significantly increased the cv. Reyan No.4 yield in the order of P〉K〉N. The NPK combination for the highest yield was urea 399.08 kg/hm^2 FCMP 224.40 kg/hm^2 and potassium chloride 60.38 kg/hm^2, and yielded 385.0 t/hm^2, with the optimal NPK ratio being W(N) : IV(P2O5) : W(K2O) = 5.07 : 1.12 : 1. The NPK combination for the highest profit was urea 413.1 kg/hm^2, FCMP 207.9 kg/hm^2 and potassium chloride 156.1 kg/hm^2, with the ratio being W(N) : W(P2O5) : W(K2O) = 6.33 : 1.25 : 1. and produced 384.90 t/hm^2 and 56 341 yuan/hm^2.
