【摘要】 为探讨冀南麦区中上等肥力壤土条件下小麦高产栽培的适宜播种方式,以当地主推的水肥高效型小麦品种邯6172、石麦15和科农199为试验材料,研究了4种播种方式〔宽窄行条播(宽行18 cm,窄行12 cm)、12 cm等行距条播、15 cm等行距条播、撒播〕对小麦产量、产量构成因素、有效分蘖成穗率、收获指数和叶面积指数等主要性状的影响。结果表明:冀南麦区小麦高产栽培的适宜播种方式依次为宽窄行条播(宽行18 cm,窄行12 cm)、12 cm等行距条播、15 cm等行距条播,其中,邯6172的最佳播种方式为宽窄行条播(宽行18 cm,窄行12 cm),石麦15的最佳播种方式为12 cm等行距条播,科农199的最佳播种方式为15 cm等行距条播。撒播虽形成了较多的穗数,但有效分蘖成穗率低,穗粒数少、千粒重低是导致其产量低的主要因素,因此在冀南麦区不适宜选用。更多还原

【Abstract】 Using Han 6172,Shimai 15 and Kenong 199 as the materials,4 kinds of sowing methods including wide-narrow row drilling(18 cm of wide row,12 cm of narrow row),12 cm equal row spacing drilling,15 cm equal row spacing drilling and broadcasting were set,and the effects of 4 kinds of sowing methods on the main characters of wheat including yield,yield component factors,effective tillering rate,harvest index and leaf area index etc.were researched to explore the suitable sowing methods of high-yielding cultivation of wheat in middle and high fertility soil conditions for southern of Hebei Province.The results showed that the order of suitable sowing methods of wheat high-yielding cultivation in southern of Hebei Province was wide-narrow row drilling(18 cm of wide row,12 cm of narrow row),12 cm equal row spacing drilling,15 cm equal row spacing drilling.The best sowing methods of Han 6172,Shimai 15 and Kenong 199 in southern of Hebei Province was wide-narrow row drilling(18 cm of wide row,12 cm of narrow row),12 cm equal row spacing drilling,15 cm equal row spacing drilling,respectively.Although more spikelets was formed by broadcasting,the low effective tillering rate,the less grain number per spike and low 1000-grain weight were the main factors leading to the low yield of wheat,therefore broadcasting was not the suitable sowing method of wheat in southern of Hebei Province.更多还原
