摘要
为研究不同小麦品种混播对产量及产量要素的影响,在我国小麦种植的核心区域河南省安阳市进行试验。试验品种以在当地种植面积较大的周麦27、安麦1241、百农207和安麦34为基础品种,通过不同比例混播种植后,测定产量和产量要素。结果表明:在2个混播试验中,安麦1241的有效穗数为737.40万个/hm^(2),容重为830.33 g/L,千粒质量为49.55 g,单穗质量为1.90 g,产量为9054.69 kg/hm^(2),在Ⅰ组中均为最高;安麦34的最高蘖数为1416.00万个/hm^(2),有效穗数为763.05万个/hm^(2),千粒质量为49.14 g,产量为9354.17 kg/hm^(2),在Ⅱ组中均为最高;周麦27的最高蘖数为1272.90万个/hm^(2),容重为810.67 g/L,千粒质量为35.73 g,单穗质量为1.34 g,产量为6930.99 kg/hm^(2),在Ⅰ组中均为最低;百农207有效穗数为601.65万个/hm^(2),千粒质量为40.49 g,产量为7152.34 kg/hm^(2),在Ⅱ组中均为最低。2组混播小麦容重变幅较小,最大变幅不超过±0.87%;Ⅰ组混播处理C、D、E的产量较理论产量分别下降了0.31%、4.59%和8.20%;Ⅱ组混播处理J、K、L的产量较理论产量分别下降了3.62%、4.93%和5.20%。
In order to determine the effects of mixed sowing of different wheat varieties on wheat yield and yield components,a field trial was carried out in Anyang City,Henan Province,the core area of wheat planting in China.The tested wheat varieties were Zhoumai 27,Anmai 1241,Bainong 207,and Anmai 34,which are planted widely in the local area.The trial consisted of two groups of treatments(Ⅰ and Ⅱ),five each.Group Ⅰ consisted of treatments A—E;Zhoumai 27 and Anmai 1241 were planted alone in treatments A and B,respectively,while they were mixed in different proportions in treatments C,D,and E for planting.Group Ⅱ comprised treatments H—L;Bainong 207 and Anmai 34 were planted alone in treatments H and I,respectively,while they were mixed in different proportions in treatments J,K,and L for planting.The yield and yield components were measured in each treatment.In Group Ⅰ,Anmai 1241 showed the effective panicle number of 7.374 million/hm^(2),unit weight of 830.33 g/L,1000-grain weight of 49.55 g,single panicle weight of 1.90 g,and yield of 9054.69 kg/hm^(2),which were consistently the highest values in the group.In Group Ⅱ,Ammai 34 had the highest tiller number of 14160000/hm^(2),effective panicle number of 7630500/hm^(2),1000-grain weight of 49.14 g,and yield of 9354.17 kg/hm^(2),which were consistently the highest values in the group.In Group Ⅰ,Zhoumai 27 had the highest tiller number of 12729000/hm^(2),unit weight of 810.67 g/L,1000-grain weight of 35.73 g,single spike weight of 1.34 g,and yield of 6930.99 kg/hm^(2),which were consistently the lowest values in the group.In Group Ⅱ,Bainong 207 had the effective panicle number of 6016500/hm^(2),1000-grain weight of 40.49 g,and yield of 7152.34 kg/hm^(2),which were consistently the lowest values in the group.In the two groups,mixed sowing treatments varied slightly in unit weight,whose maximum variations were within±0.87%.The yields of the mixed seeding treatments C,D,and E in Group Ⅰ decreased by 0.31%,4.59%,and 8.20%,respectively,compared with thei
