不同熟期覆膜春大豆生育特性及产量、品质的比较研究

Comparative Research of Growth Character And Yield,Quality Of Spring Soybendby Covered Film under Diferent Mature Period

为研究不同熟期春大豆覆膜后生育特性及产量品质变化规律,以3个不同熟期春播大豆品种(系)为材料,研究其在地膜覆盖条件下生育规律及产量变化情况。结果表明:各品种覆膜较露地生育进程明显提前,在前期表现更加突出,各个阶段的生长量显著增加,株高、节数、株荚数、株粒数、百粒鲜重均大于露地,同时覆膜品(系)间,收获期最早的品系是黑河17(8月29);最晚是九农26,其中九农26单株荚数、单株粒数、百粒重及产量均居首位,就综合性状而言,九农26最适合在本地区春播覆膜高产种植。

in order to study on the regularity of growth and yield component of coverlay film spring soybean, using 3 different mature period spring soybean varieties as material , the results indicated that the growing proless of coverd spring soybean was apparenyly advanced. The amount of growth in each stage was increased significantly , stem hight, while the pods of single plant, seeds of single plant, yield of per plant and the total yield were increaser than open ground, Heihel7 is the earest harvestry;while Jiunong26 is the fastest harvestry, the character of yield is the best, total estimated Jiunong26 is the fittest covered by film in Xinjiang.
