【摘要】 通过盆栽试验条件,设置不同灌水和施肥处理,研究水肥耦合对大豆生长的影响。试验结果分析表明:水分对大豆的生长影响大于肥的影响,大豆生长很大程度上依赖于水分供应的多少,在水分充足时增加施肥可以提高大豆产量和株高,但水分过高对大豆生长不利。总体上,随着水分和施肥量的增加,产量增加,在相对含水量55%、N含量为200mg/kg、P为50mg/kg、K为100mg/kg时对大豆的生长最适合。
【英文摘要】 Pot experiments were conducted to determine the effects of water and fertilizer coupling on yield of soybean by designing different water and fertilizer treatments. The results showed that the yield of soybean was strongly dependent on water supply, sufficient water supply significantly increased the yield and plant height of soybean. However, excessive water supply negatively influenced the yield of soybean. As a whole, the yield of soybean will increase with increased water and fertilizers supply. At the ...
在影响作物生长的水、肥、气、热等诸多因素中,肥、水两因子起着决定性作用,是作物生产力水平提高的关键因素。水是肥效发挥的关键,肥是打开水土系统生产效能的钥匙,肥水关系失调意味着植物生长过程的衰退和停止,因此研究水肥之间的关系对农业生产意义重大。水肥是最易被人所控
