| 摘 要： | 对春播花生"台南13"进行了播种期、穴播粒数、种植密度及施氮量四因素正交高产试验,结果表明:播种期4月4日,每穴播3粒种,种植密度16 67万穴/hm2,施纯氮45kg/hm2为最优组合;种植密度对产量的影响最大,其次是施氮量和穴播粒数,播种期的影响最小。另外就各因素对产量结构的影响作了简要分析。

Effects of Four Factors on Yield and Yield Components of Spring Peanut "Tainan 13" |
| |
| Abstract: | The four factors (sowing date, sown seeds per bunch, planting density and application rate of nitrogen fertilizer) orthogonal experiment in high yield of spring peanut "Tainan 13" was conducted, the results showed that the optimum treatment combination was sowing 3 seeds per bunch on the 4th of April, planting 16.67 ten thousand bunches per hm~2, and applying 45kg pure nitrogen per hm~2. Planting density had the greatest influence on the yield, followed by application rate of nitrogen fertilizer and sown seeds per bunch, while sowing date had the weakest effect on the yield. In addition, the effects of above four factors on the yield components were briefly analyzed in this paper. |
