不同肥料对黑龙江省极早熟高粱品种产量及品质性状的影响

Effects of Different Fertilizers on Yield and Quality Characters of Extremely Early Maturing Sorghum Varieties in Heilongjiang Province

为促进黑龙江省高粱产业的发展,以3个极早熟高粱品种为试验材料,采用裂区试验设计,分析不同肥料处理对高粱产量和品质等性状的影响。结果表明,3个品种的产量在不同试验点不同肥料处理间均有差异,龙杂19在哈尔滨、克山和黑河3个试验点产量最高的施肥处理及产量分别为复合肥处理(6836.27 kg·hm^(-2))、长效缓释肥处理(6691.15 kg·hm^(-2))和生物复混肥处理(7303.75 kg·hm^(-2));龙杂20在哈尔滨、克山和黑河3个试验点产量最高的施肥处理和产量分别为复合肥处理(7725.61 kg·hm^(-2))、生物复混肥处理(7185.00 kg·hm^(-2))和长效缓释肥处理(7167.15 kg·hm^(-2));齐杂722在哈尔滨、克山和黑河3个试验点产量最高的施肥处理及产量分别为长效缓释肥处理(6808.44 kg·hm^(-2))、长效缓释肥处理(6662.51 kg·hm^(-2))和复合肥处理(7151.48 kg·hm^(-2));不同肥料对高粱农艺性状的影响无显著规律;3个高粱品种的籽粒品质性状,在施用生物复混肥时均有一定的提高。

In order to promote the development of sorghum industry in Heilongjiang Province,the effects of different fertilizer treatments on the yield and quality of sorghum were by analyzed split-plot experiments design using three extremely sorghum varieties.The results showed that the yield of the three varieties varied among different experimental sites and fertilizer treatments.The fertilization treatments with the highest yield of Longza 19 in Harbin,Keshan and Heihe were compound fertilizer treatment(6836.27 kg·ha^(-1)),long-term slow-release fertilizer treatment(6669.15 kg·ha^(-1)),and biological compound fertilizer treatment(7303.75 kg·ha^(-1));The fertilization treatments with highest yield of Longza 20 at three experimental sites were compound fertilizer treatment(7725.61 kg·ha^(-1)),biological compound fertilizer treatment(7185.00 kg·ha^(-1)),and long-term slow-release fertilizer treatment(7167.15 kg·ha^(-1));The fertilization treatments with highest yield of Qiza 722 at three experimental sites were long acting slow release fertilizer treatment(6808.44 kg·ha^(-1)),long acting slow release fertilizer treatment(6662.51 kg·ha^(-1)),and compound fertilizer treatment(7151.48 kg·ha^(-1)).There was no significant effect of different fertilizers on the agronomic traits of sorghum;The grain quality traits of the three varieties were significantly improved when applying biological compound fertilizers.
