运用裂区设计,研究不同密度对遵义地区玉米主推品种的产量及其相关性状的影响。结果表明：适当提高玉米生产上推广的密度,有利于产量的提高;而且密度对穗粗、穗长、秃尖的影响较为明显,在较高密度下穗粗、穗长明显低于低密度的处理,而高密度的处理秃尖明显大于低密度的处理。综合考虑：适当地增加密度是提高遵义地区玉米产量的有效途径。

With the method of the split block design,the effects of density on the yield and related traits of maize main push variety in Zunyi area were studied.The results indicated that it was beneficial to increase production for increasing density.The density had more significant impact on the ear diameter,ear length and bald.At higher densities,ear diameter and ear length were significantly lower than the processing of low-density.The bald tip in the processing of high-density was significantly greater than that of the low-density processing.Considered that it was beneficial for the yield of maize to increase density and agronomic traits in Zunyi area.
