摘要
1998～ 1999年以掖单 2 2号为材料 ,采取塑盘育苗带土移栽与麦田套种、麦收后直播 3种不同种植方式 ,研究了夏玉米的生长发育进程、植株高度、田间生长整齐度和叶面积系数、根系发育、干物质积累以及产量情况 ,明确了夏玉米塑盘育苗带土移栽的方式比麦田套种和麦后直播具有明显的生长发育优势和增产效果 。
Developmental process,plant height,plant synchronization,leaf area index,root system development, dry matter accumulation and grain yield of summer maize grown under the three planting conditions:seedling transplanting,sowing before or after harvesting of wheat were studied in 1998~1999 using the cultivar Yedan 22 as the material.The results showed that the transplanting of seedlings raised in a plastic plate was clearly superior in development and yield to direct sowing,which provided a scientific foundation of modification of planting patterns of summer maize.

The growth rate in the growing season is defferent, the peak of Astragalux adsurgens Pall. population is August, and that of fobs July. The parts which a plant grows branches are distributed to the 0cm～60cm canopy. The relation between the above ground biomass and monthly average temperature is positive(r=0.68).
