为明确大豆结瘤和生长对氮、磷肥的响应规律，利用温室盆栽试验，在3种氮浓度(0，200和500 mg·kg-1)和3种P2O5浓度(0，200和500 mg·kg-1)组合条件下，测定了大豆根瘤数、根瘤量、株高、地上部生物量、地下部生物量和荚数的变化。结果表明：500 mg·kg-1的施氮量显著抑制结瘤，磷肥可以促进结瘤并缓解氮肥对结瘤的抑制。适当的氮磷比例促进大豆生长，施200 mg·kg-1N和500 mg·kg-1P2O5时，大豆的地上部生物量和荚数均最大；不施磷只施500 mg·kg-1N时大豆地下部生物量最大。综上所述，200 mg·kg-1P2O5对大豆结瘤和生长均有促进作用；维持较高大豆产量和较高结瘤能力所需的氮肥用量是不能同步的。
- Abstract:
- The present study was carried out to explore the response of nitrogen and phosphorus fertilizer on nodulation and plant growth of soybean.Nodule number,nodule weight,shoot height,shoot biomass,root biomass and pod number of soybean were examined by pot experiment in green house under three nitrogen fertilizer(0,200 and 500 mg·kg-1)and three phosphorus fertilizer(0,200 and 500 mg·kg-1)usage.The result showed that the influence of nitrogen and phosphorus fertilizer on nodule number and weight was similar.Above 200 mg·kg-1 nitrogen fertilizer usage significantly inhibited nodulation.Phosphorus fertilizer promoted nodulation and relieved the inhibitory effect caused by nitrogen fertilizer.Plant growth of soybean was promoted by nitrogen and phosphorus fertilizer.Shoot biomass and pod number were greatly increased by combination of 200 mg·kg-1 phosphorus fertilizer and 500 mg·kg-1 nitrogen fertilizer.Root biomass of soybean was the highest by only 500 mg·kg-1 nitrogen fertilizer application.In a word,increasing phosphorus fertilizer could improve nodulation and plant growth of soybean simultaneously.While nitrogen fertilizer inhibited nodulation of soybean regardless of phosphorus usage modification.
