摘要: 探讨土壤养分平衡因素是否影响玉米产量潜力的发挥,进而阐明不同养分供应下玉米品种生物学性状和产量潜力变异及其育种意义,为品种选育与区试中应用科学的施肥技术和手段提供依据。采用田间品种对比试验,在山西汾阳碳酸盐褐土上研究不同养分供应对15个全国区试玉米品种产量潜力变异的影响。结果表明,和常规施肥相比,调控施肥改变了玉米的生物学性状,显著增加了单穗粒重和产量;不同养分供应及平衡状况下玉米品种的产量潜力有较大差异,平衡施肥使高养分潜力型品种的产量潜力得到明显提高。土壤养分与作物施肥的养分供应状况显著影响玉米产量潜力的发挥。因此,在玉米高产育种中,应该根据土壤-养分平衡原理来筛选生态适应性品种。

Abstract: To discuss whether soil nutrient balance affects corn cultivars yield potentiality and study corn agronomical properties and yield potential variation and its significance for breeding, field experiments were conducted to provide evidence for corn breeding and regional test. 15 national regional test corn cultivars were planted in carbonate cinnamon soil as field experiment in Fenyang to study the effect of different nutrient application on corn yield potential variation. Results showed that regulative fertilization changed agronomical properties compared with conventional fertilization and increased significantly grain weight of one spike and grain yield. There was obviously difference for corn yield potentiality under different nutrient application and fertilizer balance, and balanced fertilization increased significantly yield potentiality for high nutrient potential cultivars. Soil nutrient and nutrient from application affected corn yield potentiality. Therefore, ecoadaptable cultivars should be chosen according to soil nutrient balance theory in corn high-yield breeding.

Key words: Corn, Cultivars, Nutrient application, Agronomical properties, Grain yield, Balanced fertilization
