Optimization of Maize Plant Spacing in Soybean-Maize Strip Intercropping Systems
摘要
Abstract
To investigate the optimal planting density for achieving high maize yield and to optimize maize plant spacing,a field experiment was conducted exploring soybean-maize strip intercropping following the harvest of wheat or rapeseed.Five different maize plant spacing treatments were established to study their effects on maize yield and agronomic traits.The re-sults showed that maize yield gradually increased with the reduction of plant spacing.Ear length,ear diameter,kernels per ear,grain weight per ear,and 100-kernel weight initially increased and then decreased,while bare tip length showed a gradual increasing trend.The treatments with plant spacings of 18 cm(density of 3 078 plants/667 m2)and 21 cm(density of 2 646 plants/667 m2)demonstrated favorable performance in both yield and agronomic traits.关键词
