在“玉/豆”套作模式下,采用随机区组设计,研究磷、钾营养对套作大豆干物质积累、分配及产量的影响。结果表明,完熟期套作大豆干物质积累总量及根、茎、叶、荚各器官干物质积累量均随施钾量增加而增加,随施磷量增加呈先升高后降低的趋势,且都以磷肥17千克/公顷,钾肥112.5千克/公顷处
Under the “jade / bean” intercropping system, random block design was adopted to study the effects of phosphorus and potassium on dry matter accumulation, distribution and yield of intercropped soybean. The results showed that the dry matter accumulation of dry matter and the accumulation of dry matter in roots, stems, leaves and pods increased with the increase of potassium application in the maturing stage, and then increased first and then decreased with the increase of phosphorus application, And are phosphate fertilizer 17 kg / ha, potash 112.5 kg / hectare
