| 通过不同灌水和施肥处理,研究水肥耦合对大豆光合特性及产量品质的影响,结果表明:大豆光合速率变化趋势很大程度上依赖于水分供应的多少,在水分充足时增施无机肥可以提高大豆的光合速率,产量随着水分和施肥量的增加而增加,在充足水分和无机肥+有机肥耦合情况下,产量最高(2124.5kg/hm2),比无肥干旱增产83.2%。干旱条件下,无机和有机肥配合有利于蛋白质的积累,而充足水条件下,无机和有机肥配合不利于蛋白质的积累,有利于脂肪的积累。 |
| 英文摘要: |
| Effects of water and fertilizer coupling on photosyntheti c characteristics and yield/quality of soybean were investigated at conditions wit h different water and fertilizer treatments. The results showed that leaf photos ynthetic rate of soybean was strongly dependent on water supply. Under the condi tion of sufficient water, the photosynthetic rate was incereased when chemical f ertilizers were applied, and yields of soybean were increased with the increment of water and fertilizer. Under the condition of sufficient water combined w ith chemical fertilizer and manure, the maximum yield (3 124.5 kg/hm2) was o btai ned, with the increase rate of 83.2% compared to drought and no fertilizer. The combination of chemical fertilizer with manure was beneficial to the accumul atio n of protein when water supply was inadequate. However, it was not beneficia l to protein accumulation but good for fat accumulation when water supply was suffie ient. |
