不同种植模式对夏玉米生长特性及产量的影响

Effect of Different Planting Patterns on growth characteristics and yield of summer maize

通过田间试验,采用常规垄作种植和小麦、玉米一体化垄作种植模式,研究了不同水分控制下限对夏玉米的生长特性和产量的影响.结果表明：与常规种植模式相比,一体化垄作种植模式延缓了夏玉米的衰老时间,促进作物生长发育,株高、叶面积指数和茎粗均有不同程度提高,且产量增加174.91～817.49 kg/hm2;不同种植方式夏玉米生长特性指标与水分处理大致呈正相关,但是随着水分控制下限的提高,夏玉米产量达到峰值之后下降明显;通过产量及其构成因子的比较,确定了夏玉米适宜种植方式和水分处理.

Using wheat, corn integration ridge tillage furrow planting pattern and conventional furrow planting pattern, study dltterent moisture content control limit that effects on growth characteristics and the summer corn yield through field experiment. The results show that：Compared with the conventional planting pattern, integration ridge tillage planting pattern delayed the aging time, promoted crop growth and development,plant height, leaf area index and stem diameter were improved , and the yield increased 174.91 - 817. 49 kg/hm2. Different planting patterns on summer maize growth characteristic parameters and water treatment performance index was positively correlated roughly, but with the increased of moisture content control limit, summer maize yield decreased significantly after the peak. Through comparison of yield and its component factors, determined the appropriate planting pattern and water treatment of summer maize.
