以耐密型玉米辽单565为试验材料,研究不同氮、磷、钾肥配施对其光合特性和产量的影响。结果表明,氮肥试验中,辽单565穗上叶和穗位叶叶面积、穗位叶和穗下叶光合速率均以施氮量为135千克/公顷时达到较高值,叶面积指数较高,穗位层叶片消光系数较小,产量较高;磷肥试验中,辽单565穗上叶和穗位叶叶面积、
The study was conducted to study the effects of different nitrogen, phosphorus and potassium fertilizers on photosynthetic characteristics and yield of Lidan 565. The results showed that in nitrogen fertilization experiment, the leaf area, ear position and ear lower leaf photosynthetic rate of upper leaves and ears of Liaodong 565 reached higher value with the nitrogen application rate of 135 kg / ha and the leaf area index was higher , The spike layer leaves extinction coefficient smaller, higher yield; phosphate fertilizer experiment, Liao Dan 565 spike leaf upper ear area and leaf area,
