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%。
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.
