目前我国大豆供需矛盾突出,近80%的大豆依赖进口,开展玉米-大豆条带复合种植,即在不影响玉米产量的情况下,获得一定产量的大豆,是解决这一问题的有效途径。本试验选用紧凑型玉米品种(良玉88、铁研58、东单6531)和耐荫型大豆品种(辽豆32、沈农8号、辽豆15)为试验材料,组配良玉88-辽豆32﹑良玉88-沈农8号、良玉88-辽豆15、东单6531-辽豆32、铁研58-辽豆32五个组合,进行带状复合种植,以期从中选择出适合于辽宁地区玉米-大豆带状复合种植的品种组合方式。结果表明:良玉88-辽豆32组合玉米大豆总产量最高,其次为东单6531-辽豆32组合和铁研58-辽豆32组合。在玉米-大豆带状复合种植中,应选择单株荚数、单株粒数、单株粒重有优势的大豆品种,选择穗行数和行粒数有优势的玉米品种。综合考虑玉米和大豆性状的组合,良玉88-辽豆32组合的综合性状较好,是适宜辽宁省玉米-大豆带状复合种植的品种组合。
At present, the contradiction between the supply and demand of soybean in our country is prominent. Nearly 80% of the soybean is dependent on the import. It is an effective way to solve this problem that corn and soybean strip should be planted in a compound way, that is to say, to get a certain yield of soybean without affecting the yield of corn. In this study, compact maize varieties (Liangyu 88, Tieyan 58 and Dongdan 6531) and shade-tolerant soybean varieties (Liaodong 32, Shennong 8 and Liaodou 15) were selected as experimental materials, and Liangyu 88-Liao Beans 32, Liang Yu 88- Shennong 8, Liangyu 88-Liaodou 15, Dongdan 6531- Liaodong 32, Tieyan 58- Liaodou 32 five combinations, the ribbon compound planting, with a view to select suitable for Variety Combination of Corn and Soybean Planted in Liaoning Province. The results showed that the total yield of Liangyu 88-Liaozu 32 combined corn was the highest, followed by Dongdan 6531-Liaodong 32 combination and Tieyan 58-Liaodong 32 combination. In the corn-soybean compound planting, the soybean varieties with the advantages of pod number per plant, grain number per plant and grain weight per plant should be selected, and the corn varieties with the preferred number of rows and grains per row should be selected. Considering the combination of traits of maize and soybean, the comprehensive traits of Liangyu 88-Liaodou 32 combination are better, which is the suitable combination of corn-soybean compound planting in Liaoning Province.
