| 摘 要： | 用二次回归通用旋转组合设计研究了不同播种量、有机肥与N,P,K肥用量对稻板大麦产量的影响,利用电子计算机模拟选优,结合考虑经济效益,获得了本试验条件下>350 kg/mu并具有最高经济效益的最佳农艺措施组合方案:播种量7.5kg/mu(基本苗15万/mu),有机肥(厩肥)1500 kg/mu,化学氮肥(N)8.05 kg/mu,磷肥(P_2O_5)2 kg/mu,钾肥(K_20)12 kg/mu,文中对上述农艺因素对产量构成因子的影响也作了讨论。

| Abstract: | The effect of applying different rates of seed,manure,N,P and K on the grain yield of barley sown on no-till paddy field was studied in commonly used,rotational and conbinatorial design of quadratic regression.The best conbinatorial scheme of agronomic measures was obtained through simulating and optimalization to achieve a grain yield of more than 350 kg/mu with the highest economic benifit condition was the same as this experiment,with the sowing seed rate of 7.5 kg/mu,and manure,N,P and K applied at the rate of 1500,8.05,2 and 12 kg/mu respectively.The effect of above-mentioned agronomic measures on yield component was discussed. |
