叶面喷施微肥对花生产量及品质的影响

Effects of Spray Application of Microelement Fertilizer on Peanut Yield and Quality

采用随机区组设计,研究了叶面喷施微肥对花生产量及品质的影响。结果表明:在一定的N、P、K肥供给水平上,喷施硼、锌、钙、钼等单一微量元素处理,花生荚果产量增幅为6.00%～8.38%,籽仁产量增幅为6.66%～8.96%;喷施硼锌处理,荚果产量和籽仁产量分别增加13.05%和13.06%;喷施硼钙处理,荚果产量和籽仁产量分别增加12.44%和14.21%;叶面喷施微肥各处理荚果和籽仁增产均达到极显著水平。喷施硼锌处理花生蛋白质含量和油亚比分别增加0.60个百分点和0.34,喷施硼钙处理脂肪含量和油酸/亚油酸比值分别增加0.20个百分点和0.27。综合分析,在供试条件下,喷施禾丰硼(450g/hm2)+禾丰锌(270g/hm2)或喷施禾丰硼(450g/hm2)+果蔬钙肥(675mL/hm2)能显著提高花生产量和品质。

Effects of different microelement fertilizers on the yield and quality of peanuts were studied by using a randomized block design.The results showed that when N,P and K were applied at appropriate levels,spraying single-microelement fertilizers,like P,Zn,Ca and Mo,increased pod yield and seed kernel yield of peanuts by 6.00%-8.38% and 6.66%-8.96%,respectively;by spraying B and Zn fertilizers,pod yield and seed kernel yield reached 5 339.0 kg/ha and 3 677.3 kg/ha,a marked increase of 13.05% and 13.06%,respectively;likely,spraying B and Ca fertilizers raised pod yield and seed kernel yield to 5 309.8 kg/ha and 3 714.8 kg/ha,increased by 12.44% and 14.21%,respectively;obviously,the yield of peanut pods and seed kernels showed an extremely significantly level under spraying different microelement fertilizers.Moreover,spraying B and Zn fertilizers increased the content of protein and O/L by 0.60 percentile and 0.34,respectively;Fat content and O/L were raised by 0.20 percentile and 0.27,respectively,according to spaying B and Ca fertilizers.The research showed that spraying B（450 g/ha）＋Zn（270 g/ha） or B（450 g/ha）＋Ca（675 mL/ha） fertilizers could significantly enhance the yield and quality of peanuts.
