摘要
选取鲁单818为试验材料,研究了不同种植方式对夏玉米干物质积累及产量的影响程度。结果表明,在整个生育期,夏玉米在个体和群体层次上干物质积累均呈S型动态变化,各阶段单株干物质积累速率及群体生产率呈单峰曲线动态变化,在相同的生育时期,以三株种植的玉米在干物质积累量及阶段积累速率较大;不同种植方式以三株种植的玉米产量最高。
Using maize Ludan 818 as the material, researched the effects of different planting patterns on the dry matter accumulation and yield. The results showed that the dynamics of dry matter accumulation of single plant and population were S curve,and the dynamics of the rate of dry matter phrase accumulation and population phrase productivity were single peak curve. The dry matter accumulation and the phrase accumulation rate of the pattern of three strains plant were more at the same growth period. The yield of three strains plant was the highest in different planting patterns.
