摘要
为探索小麦新品种南麦302在生产上的种植模式,在川东北丘陵旱地用双因素试验研究了带宽和播种方式对南麦302产量的影响,结果表明带宽和播种方式对南麦302产量均有影响.带宽对产量影响极显著,以"双三尺"产量最高,但"双三尺"、"双四尺"垒厢、"双四尺"不垒厢、"双五尺"4种带宽产量差异不显著.播种方式对产量影响也极显著,以窝播产量最高.播种方式和带宽的互作对产量影响不显著.因此,在川东北丘陵旱地套作种植小麦新品种南麦302,应选择带宽"双三尺"、"双四尺"垒厢、"双四尺"不垒厢、"双五尺"窝播这4种模式为高产种植模式.
The effects of bandwidth and sowing pattern on the yield of Nan302, a new wheat cultivar, were studied using the dual-factor test in a hilly area in northeastern Sichuan. The results showed that band width and sowing pattern had significant influence on wheat yield. The yield with bandwidth ＂3 feet 3 feet＂ was the highest, whereas there was no significant difference among the yields with four bandwidths： ＂3 feet 3 feet＂, ＂4 feet 4 feet＂ （barrier bed）, ＂4 feet 4 feet＂ （no barrier bed） and ＂5 feet-5 feet＂. The yield with nest sowing was also the highest and the interaction between bandwidth and sowing pattern had no significant influence on yield. Therefore the high yield planting patterns for Nan302 in hilly areas of northeastern Sichuan were nest sowing with bandwidth ＂3 feet-3 feet＂, ＂4 feet 4 feet＂ （barrier bed）, ＂4 feet-4 feet＂ （not barrier bed） or ＂5 feet 5 feet＂.
