研究不同种植密度对新玉59农艺性状及产量的影响。结果表明:随着种植密度的增加,新玉59的株高、穗位上升,秃尖变长,穗长变短,穗行数减少,行粒数减少;密度的变化对生育期、空秆率和穗粗的影响较小;产量随种植密度的增加而增加,在7 000株/666.7m2时产量最高,达1 193.6 kg/666.7m2,表明新玉59在昌吉地区适宜高密植。
Effects of Different Planting Density on Agronomic Characters and Yield of. The results showed that with the increase of plant density, the plant height and ear position of Xinyu 59 increased, the length of bald tip became longer, the spike length became shorter, the number of ear rows decreased and the number of rows per plant decreased. The change of density had no significant effect on the growth period, Yield and ear diameter had little effect. The yield increased with the increase of planting density, and reached the highest at 1 193.6 kg / 666.7 m2 at 7 000 plants / 666.7 m2, indicating that Xinyu 59 is suitable for planting in Changji area.
