摘  要：
以耐密型玉米品种“吉单209”为试材,研究了不同氮、磷用量对玉米籽粒产量和营养品质的影响。结果表明:不同氮、磷营养水平对玉米籽粒产量影响较大,本试验条件下适宜的施肥量为N 200 kg/hm2、P2O560 kg/hm2、K2O 50 kg/hm2,经济施氮量为174.4 kg/hm2。氮肥对玉米籽粒蛋白质含量、赖氨酸含量的影响明显,在施磷30 kg/hm2时,施氮250 kg/hm2比施氮100 kg/hm2处理蛋白质含量增加3.9%,蛋白质产量增加10.1%。在一定的范围内玉米籽粒脂肪含量随氮肥施用量的增加而增加,在相同氮水平时,随着施磷量的增加玉米籽粒脂肪含量增加。

摘  要：
The effects of different nitrogen and phosphorus application on grain yield and qualities of compact corn Jidan 209 were studied.The results showed that a significant difference in grain yield of corn at different levels of nitrogen and phosphorus application was found.Under this experiment condition,the suitable application amount of N,P_2O_5 and K_2O was respectively 200 kg/hm~2,60 kg/hm~2 and(50 kg/hm~2),and the economical N application amount was 174.4 kg/hm~2.The effect of N application on corn grain protein content and lysine content was observed.When P amount was(30 kg/hm~2),to vary N amount from 100 kg/hm~2 to 250 kg/hm~2,corn grain protein content would increase by 0.33% and yield would increase by 10.1%.With the increase of N amount,corn gain oil content increased within certain level.With the increase of P amount,corn gain oil content increased in the same N level.
