摘要
[目的]确定优质杂交水稻品种为天9号的最佳氮、磷、钾、锌施肥配比。[方法]以为天9号为供试品种,采用L9(34)正交设计研究不同施肥水平对为天9号产量和品质的影响。[结果]氮肥是影响为天9号产量和米质的最大控制因素,最佳施肥组合为N2P3K3Zn3,即氮、磷、钾、锌肥用量分别为195、150、150、15 kg/hm2,可获得9 750 kg/hm2以上的高产。[结论]为天9号高产优质的施肥原则为适量施用氮肥,增施磷、钾肥,微量补充锌肥。
[Objective] The study aimed to confirm the best fertilization ratio of the nitrogen,phosphorus,potassium and zinc for the hybrid rice variety Weitian 9.[Method] With the hybrid rice variety Weitian 9 as the tested material,the L9(34) orthogonal design was used to studied the effects of different fertilization levels on the yield and quality of Weitian 9.[Result]The nitrogen fertilizer was the greatest controlling factor for the influence on the yield and rice quality of Weitian 9.The best fertilizer combination was N2P3K3Zn3,namely,the dosages of the nitrogen,phosphorus,potassium and zinc fertilizers were 195,150,150,15 kg/hm2,which could get the high yield of above 9 750 kg/hm2.[Conclusion] The principle for getting the high yield and good quality of Weitian 9 was the application of nitrogen fertilizer with the right amount,the increased fertilization of the phosphorus and potassium and the supplement application of trace zinc fertilizer.
