摘要
利用不同配方控释肥,在花生大田试验中与普通复合肥进行对比试验,研究了不同施肥处理对花生生理特性、农艺性状、产量、品质的影响。结果表明,与普通肥料相比,施用控释肥料提高了花生叶片叶绿素含量、光合速率、蒸腾速率、干物质积累量等生理指标,对花生主要的农艺性状有显著改善作用。同时与普通肥料相比,控释肥料处理增加荚果产量7.16%～8.35%,增加籽粒产量5.60%～8.28%。此外,控释肥料还可以提高花生籽粒的粗蛋白、粗脂肪、可溶性糖和Vc含量,显著改善了花生的品质。
Field experiment was conducted to study the effect of different controlled release fertilizers on growth of peanut in comparison with common compound fertilizer and to investigate the effect of different fertilizers treatments on physiological characteristics,yield and kernel quality of peanut.The result showed that the controlled release fertilizers could increase the leaf chlorophyll content,photosynthetic rate and transpiration rate in CRF treatments were better than those in common compound fertilizer treatment and control.Comparing to applying common fertilizers,At the same time,the controlled release fertilizers improved the agronomic characteristics of peanut and pod yield of peanut by 7.16%～8.35%,kemel yield by 5.60%～8.28%.In addition,the controlled release fertilizers also showed a beneficial result on the peanut quality,and improved the protein,fat,soluble sugar and vitamine C content in seed compared to common compound fertilizer.
