为明确育苗移栽对玉米生育进程、植株性状及产量构成的影响,以郑单958和京单68为材料进行了试验,结果表明:移栽处理后玉米株高、穗位高、穗长和穗粒数分别较直播对照下降,但生育进程明显提前7~10d,灌浆较充分,子粒含水量降低26.9%和31.3%,产量增加12.3%和10.4%,郑单958产量差异达到显著水平。
In order to clarify the effects of transplanted seedlings on the growth process, plant traits and yield components of maize, we conducted the experiments with Zhengdan 958 and Jingdan 68. The results showed that the plant height, ear height and ear length Compared with the direct seeding control, the spikelets number decreased, but the fertility progress was obviously advanced 7 ~ 10d. The grain filling was more adequate, the seed moisture content decreased by 26.9% and 31.3%, the yield increased by 12.3% and 10.4%, and the yield difference of Zhengdan 958 reached the significant level.
