营养型大豆重迎茬专用肥筛选试验研究

【摘要】 采用田间进行了重迎茬大豆专用肥筛选,结果表明:NPK不同组合可明显促进重迎茬大豆生长发育,主要表现在增加了大豆株高、提高大豆地上和地下生长;增加了干物质积累、根瘤数量;增加了营养生长时期根/冠比值。进而提高产量,以处理2产量最高,增产达到17.15%。更多还原

【Abstract】 Screening experiment of continuous cropping and alternate-year fertilizer for nutritional-type soybean was conducted in the field,the results indicated that NPK different combinations could improve development of soybean obviously.Plant height,soybean growth of above-ground and under-ground,dry matter accumulation,a number of root nodule,root cap ratio of vegetative growth stage were increased,at the same time,the soybean yield was increased by 17.5%,the treatment2 reached the highest yield.更多还原
