摘要
于始花后的不同天数给植株叶片喷施营养液（Ｎ，Ｐ，Ｋ，Ｃａ，Ｂ，Ｍ。等），并给植株中下部果针施用植物生长调节剂（１０ｐｐｍ６—ＢＡ和５ｐｐｍＧＡ３），结果表明，营养液和生长调节剂同时使用，能显著提高叶片的光合速率，促进和吸引植株中光合产物向荚果中运输和积累，使单株荚果数增加，特别是高节位的荚果数增加；同时使饱果率、百果重提高，花生平均增产８．６％—２０％。
In a field trial,peanut(Arachis hypogaea Shan You No.27)plants were sprayed with nutrition element solution (N.P.K.Ca.B.Mo.etc)and plant growth regulators solution (10ppm 6-BA and 5 ppm GA3)in different days after the begining of flowering in plant.The resultS showed that net photosynthetic rate of peanut plantS and export of assimilates from leaf to pod were promoted by nutrition element solution and plant growth regulator solution.The pod yield of treated plants was higher than that of control.
