陇东旱塬区14个高粱新品种(系)在两种不同种植模式下的引种表现

以高粱品种平杂8号和平杂6号为对照,对引进的14个粒用高粱新品种(系)在陇东旱塬区全膜双垄沟播和露地宽窄行种植2种模式下进行了农艺性状和产量表现鉴定。结果表明,供试高粱品种(系)全膜双垄沟播种植比露地宽窄行种植提前成熟11~16 d,株高、穗粒重、千粒重等农艺性状和产量指标均高于露地种植。全膜双垄沟播种植时,以吉杂123折合产量最高,为14 363.70 kg/hm~2,较平杂8号(CK1)、平杂6号(CK2)分别增产25.65%、18.35%;吉杂133折合产量次之,为13 908.89 kg/hm~2,较平杂8号(CK1)、平杂6号(CK2)分别增产21.67%、14.61%。在露地宽窄行种植条件下,以吉杂127折合产量最高,为8 154.81 kg/hm~2,较平杂8号(CK1)、平杂6号(CK2)分别增产44.91%、24.92%;JN2折合产量次之,为8 144.44 kg/hm~2,较平杂8号(CK1)、平杂6号(CK2)分别增产44.73%、24.76%;吉杂133、吉杂123折合产量较高,分别为7 695.56、7 546.67 kg/hm~2,较平杂8号(CK1)和平杂6号(CK2)分别增产36.75%、34.11%和17.88%、15.60%。可见,全膜双垄沟播种植时表现最好的品种(系)有吉杂123、吉杂133,折合产量均达13 900 kg/hm~2以上,露地种植表现最好的品种(系)有吉杂127、JN2、吉杂133和吉杂123。

Introduction Performance of 14 New Sorghum Cultivars (Lines) under Two Different Planting Patterns in Dry Area of Eastern Gansu

Take the sorghum cultivars of Pingza 8 and Pingza 6 as the controls, agronomic traits and yield performance of 14 grain using sorghum cultivars (lines) are identified under ditch sowing corn in double ridge mulched with plastic film and open field planting patterns in the loess plateau region of Longdong. The result shows that the sorghum cultivars (lines) which planted by full film double furrow are matured earler 11 to 16 days than open field wide-narrow row planting, the agronomic traits of plant height, per spike grain weight and 1000 grain weight, and yield index are higher than in open field cultivation. Under the full film double furrow sowing planting pattern, the average equivalent yield of Jiza 123 is the highest, 14 363.70 kg/hm2, which is 25.65% and 18.35%higher than Pingza 8 (CK1) and Pingza 6 (CK2);the average equivalent yield of Jiza 133 is the second place, 13 908.89 kg/hm2, which is 21.67%and 14.61%higher than Pingza 8 (CK1) and Pingza 6 (CK2). In open field wide-narrow row cultivation conditions, the average equivalent yield of Jiza 127 is the highest, 8 154.81 kg/hm2, which is increased by 44.91% and 24.92%than Pingza 8 (CK1) and Pingza 6 (CK2); The average equivalent yield of JN2 is the second place, 8 144.44 kg/hm2, which is increased by 44.73%and 24.76%than Pingza 8(CK1) and Pingza 6(CK2);The average equivalent yield of Jiza 133 and Jiza 123 is higher, are 7 695.56 kg/hm2 and 7 546.67 kg/hm2, are increased by 36.75%, 34.11%, 17.88%and 15.60%than Pingza 8(CK1) and Pingza 6 (CK2). From above, in full film double furrow sowing, the best cultivars (lines) are Jiza 123 and Jiza 133, all of their average equivalent yields higher than 13 900 kg/hm2, In open field cultivation conditions, the best cultivars (lines) are Jiza 127, JN2, Jiza133 and Jiza 123.
