| 摘 要： | 在旱棚盆栽滴灌条件下研究探索滴灌水肥一体化下种植铺管模式对夏玉米氮素积累分配、土壤硝态氮含量和产量的影响。对照一管一行(65 cm等行距模式),试验设3种一管两行模式(40+90 cm、45+85 cm、50+80 cm),滴灌管铺在窄行中间。结果表明,玉米成熟期45+85 cm模式下,子粒和地上部氮积累量显著高于对照和50+80 cm模式,40+90 cm与45+85 cm模式间各器官和地上部氮积累量差异均不显著。从地表至40 cm各土层硝态氮含量均为对照模式最高,其他模式间差异不显著。50+80 cm、45+85 cm和40+90 cm模式子粒产量分别比对照高42.31%、28.00%、14.56%;与对照相比,50+80 cm、45+85 cm模式地上部干物重差异显著,分别比对照高28.52%、26.40%。综合考虑,45+85 cm和40+90 cm模式可推荐为华北区域夏玉米滴灌水肥一体化绿色增产种植铺管模式。

| Abstract: | Four kinds of pipe laying patterns were settled, i.e. one pipe between two narrow rows of plants(40+ 90 cm, 45+85 cm, 50+80 cm), and one pipe for each row of plant(65+65 cm) as control. The nitrogen accumulation in grain and shoot under 45+85 cm pipe-laying patterns were significantly higher than those of control and 50+80 cm patterns there was no significant difference between 45+85 cm and 50+80 cm patterns. the concentration of NO3-N in soils of all soil layer from surface to 40 cm underground were highest in control, and there was no significant difference among those three patterns.50+80 cm, 45+85cm and 40+90 cm patterns all recorded higher grain yield than that of the control, with the increase by 42.31%, 28.00% and 14.56%, with yield, nitrogen accumulation and the reducing of the residue of nitrogen considered, 45+85 cm and 40+90 cm could be recommended to be used for the drip irrigation in summer maize under wheat-maize rotation system in North-China Plain. |
