摘要
为了提高夏玉米的经济效益,本文通过在2015年6月至2016年10月进行的2次田间夏玉米灌溉实验。对试验田进行分块处理,设100、150、200、250、300kg/hm^2 5个氮肥使用量处理和两个灌溉2 000、3 000m^3/hm^2水平处理,测定在覆膜和非覆膜情况下对夏玉米的产量影响的实验,探讨不同水氮处理对夏玉米产量的影响。通过对2015、2016两年实验的夏玉米产量及质量的检测分析,得出对夏玉米灌溉水分越多,产量越高,在250kg/hm^2施氮量、3000m^3/hm^2灌水量的条件下,覆膜产量提高8%左右。该结论为关中地区夏玉米的最佳灌水量和施氮量提供了科学依据。
In order to improve the economic benefits of summer maize,this paper conducted two experiments on summer maize irrigation in June 2015-October 2016.The sites were treated with 100,150,200,250 and 300 kg/hm^2 of 5 nitrogen fertilizer treatments and two irrigation levels of 2000,3000 m^3/hm^2.The effects of different water and nitrogen treatments on yield of summer maize with films and without were discussed.Based on the analysis of the yield and quality of summer maize in 2015 and 2016,the higher the irrigation amount,the higher the yield,and the amount of fertilizer at 250 kg/hm^2 and the irrigation amount of 3000 m^3/hm^2,film production increased by about 8%.The conclusion provides a scientific basis for the optimal irrigation and nitrogen application rate of summer maize in Guanzhong area.
