不同缓控释肥对花生农艺性状·产量及品质的影响

Effects of Slow/Controlled-Release Fertilizer on Agronomic Traits,Yield and Quality of Peanut

[目的]研究不同缓控释肥对花生农艺性状、产量和品质的影响,为红壤条件下选择适合花生生长的缓控释肥提供理论依据和实践指导。[方法]以不同缓控释肥为材料,研究在等NPK比例和等养分量下各处理对花生农艺性状、产量及品质的影响。[结果]施用不同缓控释肥均有利于增加单株结果数和单株果重,各处理间产量差异较大,恩泰克缓释肥处理荚果及籽仁产量分别比对照增加17.27%、18.42%,差异达极显著水平,金正大控释肥处理荚果及籽仁产量分别比对照增加6.18%、9.50%。不同缓控释肥处理均提高花生籽仁粗脂肪、油酸含量及油亚比,以金正大控释肥处理提高花生品质的效果最好。[结论]若仅追求单产,可用恩泰克缓释肥;若兼顾品质,可用金正大控释肥。

[Objective] The effects of different slow/controlled-release fertilizer on agronomic characters,yield and quality of peanut were studied in order to provide theoretical basis and practical guidance for the selection of low/controlled-release fertilizer suitable for peanut growth in red soil.[Method]The experiment was conducted to research the effects of four slow/controlled-release fertilizers on agronomic traits , yield and quality of peanut at same NPK proportion and rate.[Result]The application of slow/controlled-release fertilizer could increase pod number per plant and pod weight per plant.The yield differences between the groups were obvious.Pods and seed kernel yieldt of Entek slow-release fertilizer,compared with the control increased by 17.27%, 18.42% respectively, and pods and seed kernel yield of Jinzhengda controlled-release fertilizer increased by 6.18%, 9.50% respectively. Slow/controlled-release fertilizer could also improved the content of the oil content, oleic acid,and O/L. Jinzhengda controlled-release fertilizer improved the quality of peanutbetter than other treatments.[Conclusion]If only pursue single yield,Entek slow-release fertilizer is best. If take into quality, Jinzhengda controlled-release is best.
