为探索黔油10号的丰产栽培技术模式,采取二次通用旋转回归组合设计研究其产量与主要栽培措施(密度、氮磷、钾、硼施用量)间的数量关系,并建立了各因素与产量指标间的数学模型。进一步明确了黔油10号获得2480kg/hm2以上的丰产栽培配套技术措施优化的组合是:密度11.61～12.81万株/hm2,纯N为172.46～194.55kg/hm2,P2O5为112.47～126.88kg/hm2,K2O为74.60～92.61kg/hm2,硼砂9.72～11.52kg/hm2;其中N∶P2O5∶K2O的最佳比例是2∶1.5∶1。影响黔油10号产量的主要因素是氮肥和磷肥,其次是密度、硼肥及钾肥。
In order to explore the technical mode of high yield cultivation of Qianyou 10, the quantitative relationship between yield and main cultivation measures (density, N, P, K and B) was studied by quadratic universal rotation regression combination design and the relationship between various factors Mathematical model of production index. It was further clarified that the optimal combinations of technical measures for supporting high-yielding cultivation with a yield above 2480kg / hm2 were: the density was 11.61 ~ 128.1 thousand plants / hm2, the pure N was 172.46-194.55 kg / hm2, and the P2O5 was 112.47-126.80 kg / hm2 , K2O is 74.60-92.61kg / hm2, and borax is 9.72-1l.52kg / hm2. The optimal ratio of N: P2O5: K2O is 2: 1.5: 1. The main factors influencing the yield of Qianyou 10 were nitrogen fertilizer and phosphate fertilizer, followed by density, boron fertilizer and potash fertilizer.
