以豫谷17为研究材料,采用裂区设计,研究了密度和烯效唑喷施浓度及其互作对谷子产量及产量相关性状的影响。结果表明:喷施不同浓度烯效唑对谷子有显著的增产作用,以30mg/L处理为佳;密度不同,谷子产量也有显著差异;烯效唑喷施浓度和密度的互作达极显著差异,以烯效唑30mg/L的喷施浓度和60.0万株/hm~2的密度配合最佳。随着密度的增加,单穗重和单穗粒重有所下降,喷施适当浓度的烯效唑可以缓解密度增加带来的负效应,以30mg/L处理表现最优。
Taking Yugu 17 as research material, the effect of density and uniconazole spraying concentration and its interaction on millet yield and yield-related traits was studied by split-plot design. The results showed that spraying different concentrations of uniconazole significantly increased the yield of millet, which was better at 30mg / L; the yield of millet was also significantly different with different density; the interaction between the concentration and density of uniconazole was significantly different , With uniconazole 30mg / L spraying concentration and 600000 plant / hm ~ 2 density with the best. With the increase of density, single panicle weight and grain weight of single panicle decreased. Spraying the appropriate concentration of uniconazole could alleviate the negative effect of density increase, and the optimum treatment was 30mg / L.
