辽宁省玉米大豆带状复合种植示范研究

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。

Demonstrate Research of Maize-Soybean Belt Compound Planting in Liaoning Province

At present,the contradiction of soybean supply and demand in China is outstanding.Nearly 80％ of soybean depends on imports.Maize-soybean belt compound planting is an effective way to solve this problem,without affecting maize yield and receiving some soybean production.This experiment chose the compact corn varieties (Liangyu 88,Tieyan 58,Dongdan 6531) and shade tolerance soybean varieties (Liaodou 32,Shennong 8,and Liaodou 15) as materials.They were divided into 5 combinations:Liangyu 88-Liaodou 32,Liangyu 88-Shennong 8,Liangyu 88-Liaodou 15,Dongdan 6531-Liaodou 32,Tieyan 58-Liaodou 32.The maize-soybean belt compound planting was studied to choose a suitable variety combination of maize-soybean belt compound planting for Liaoning province.The results were as follows:The total yield of Liangyu 88-Liaodou 32 combination was the highest,followed by the Dongdan 6531-Liaodou 32 combination and Tieyan 58-Liaodou 32 combination.In maize-soybean belt compound planting,soybean varieties should be chosen which were advantaged in the number of pods per plant,seeds number per plant,weight per plant,maize varieties should be chosen which were advantaged in row number and grains per row.Considering the combination of corn and soybean traits,the comprehensive character of Liang yu 88-Shennong 8 combination was the best.It was suitable for maize-soybean belt compound planting in Liaoning province.
