摘要
我国甜菜生产中施用化肥过量和不平衡现象普遍存在,因此研究合理施肥对甜菜生长和养分吸收的影响,为甜菜施肥提供科学依据.试验于2021年在哈尔滨市呼兰区进行田间试验,共设置农民习惯施肥(FP)、优化无机施肥(0F)、有机无机配施(OI)3个施肥处理,对甜菜幼苗生长参数、光合性能及中微量养分吸收进行分析.结果表明,与FP处理相比,OF和OI处理均显著提高了甜菜苗期农艺性状、叶片SPAD值和光合色素含量,增加了干物质积累量,促进了钙、镁等养分吸收.综合分析表明,有机无机配施处理对甜菜苗期生长促进效果最佳,更有利于培育壮苗,为高产群体打下良好基础.
Chemical fertilizer overuse and unbalanced application are common in sugar beet production in China.Therefore,the effect of rational fertilization on growth and nutrient absorption of sugar beet is studied to provide the scientific basis for scientific fertilization of sugar beet.The experiment was conducted in Hulan District,Harbin in 2021,and three fertilization treatments,namely,customary fertilization(FP),optimized inorganic fertilization(OF),organic and inorganic fertilization(OI),were set up to analyze the growth parameters,photosyn-thetic properties and nutrient absorption of sugar beet seedlings.Compared with FP treatment,OF and OI treatment significantly increased agronomic traits,SPAD value,photosynthetic pigment,dry matter accumulation and nutrient uptake of sugar beet at seedling stage.In conclusion,the study showed that organic and inorganic treatments had the best effect on promoting the growth of sugar beet seedlings,and were more beneficial to the cultivation of strong seedlings.
