潮土区施肥对花生不同基因型品种产量和品质的影响

Effects of Fertilization on Yield and Quality of Different Genotype Peanut Varieties on Fluvo-aquic Soil Area

为探讨潮土区花生高效施肥技术,开展了施肥对花生不同基因型品种产量和品质的影响试验,对花生农艺性状、经济性状和产量进行测定和分析。结果表明,施肥条件下,豫花9326、豫花9719和豫花9620的产量分别为6 607.8,6 750.0和6 596.9 kg·hm^(-2),较不施肥条件分别增产8.2%,18.9%,11.0%;施肥能增加不同基因型品种花生仁中棕榈酸、亚油酸、花生一烯酸、山嵛酸的含量,降低花生仁中硬脂酸、油酸、花生酸、木焦油酸的含量和油酸/亚油酸的比值;花生不同基因型品种花生仁中粗脂肪含量及产量差异显著,以豫花9326花生仁中粗脂肪产量最高(2 293.9 kg·hm^(-2)),而豫花9719花生仁中粗脂肪含量最高(50.5%)。在N、P_2O_5、K_2O施用量分别为180,120,150 kg·hm^(-2)条件下,豫花9719的荚果产量、粗脂肪含量和粗脂肪产量均最高,分别为6 750.0 kg·hm^(-2)、50.9%和2 408.5 kg·hm^(-2)。

In order to study the high-efficiency fertilization of peanut on fluvo-aquic soil,the effects of fertilization on yield and qual鄄ity of different genotype peanut varieties were studied,and the agronomic characters,economic characters and yield of peanut were measured and analyzed.The results showed that:compared with no fertilization,pod yield of Yuhua9326,Yuhua9719and Yuhua9620were6607.8,6750.0,6596.9kg窑hm-2with fertilization,increased by8.2%,18.9%and11.0%,respectively;fertilization could increase the content of palmitic,linoleic,eicosenoic docosanoic,and reduce the content of stearic,oleic,arachidic,tetra鄄cosanoic,and the ratio of oleic acid content and linoleic acid content;the crude fat content in peanut kernel and fat yield had signifi鄄cant differences in different genotype varieties,in which Yuhua9719had the highest crude fat content(50.5%)袁and Yuhua9326had the highest fat yield(2293.9kg窑hm-2).When the application rate of N,P2O5,K2O was180,120,150kg窑hm-2respectively,Yuhua9719had the highest pods yield(6750.0kg窑hm-2),crude fat content(50.9%)and crude fat yield(2408.5kg窑hm-2)in the three va鄄rieties,and also the highest.
