| 摘 要： | 采用五元二次回归旋转组合设计方法,以播种量、有机肥、氮、磷、钾作为试验因子,研究了一年生黑麦草A2003新品系的最佳播种量及其施肥水平,建立了高产栽培配套技术数学模型.结果表明:在本试验条件下,以播种量为1.2kg/167m2、有机肥2 999kg/667m2、氮30kg/667m2、磷20kg/667m2、钾20kg/667m2的组合,可获得最高产草量,达5015 kg/667m2.

| Abstract: | The quadratic regression rotational combination design was used to study effects of different N,P and K application level and sowing quantity on fresh grass yield of A2003 and the mathematical model for its high fresh grass yield was established.The results showed that 5015kg/667m2of fresh grass yield could be obtained under the cultivation conditions of 1.2kg/667m2of sowing quantity,30kg/667m2 of N,20kg/667m2 of P,20kg/667m2 of K and 2999kg/667m2 of organic manurein the test. |
