摘要
为探究始花期叶面喷施胺鲜酯、噻苯隆及其复配药剂对大豆产量和品质的调控效应,提升大豆化控应用技术水平,以垦农18为供试品种,以喷施清水为对照,以胺鲜酯、噻苯隆及其复配药剂为处理,通过桶栽试验分析比较2单剂及复配喷施对大豆产量、品质、干物质积累及蔗糖代谢的影响。结果表明:适宜浓度的胺鲜酯、噻苯隆及复配喷施可有效调控叶片蔗糖磷酸合成酶与蔗糖合成酶活性,提高叶干重及蔗糖含量,其中叶干重的提高范围分别为5.06%~22.85%、14.47%~28.50%和1.45%~6.72%,叶片蔗糖含量的提高范围分别为9.94%~19.69%、11.92%~48.57%和18.49%~118.26%,进而提升大豆产量,改善大豆品质。其中,0.2 mg·L^(-1)的噻苯隆及20 mg·L^(-1)胺鲜酯与0.1 mg·L^(-1)噻苯隆复配可使大豆单株粒重增加19.10%和19.16%,60 mg·L^(-1)胺鲜酯与0.6 mg·L^(-1)噻苯隆复配对品质提升效果佳,其可使蛋白质与脂肪含量分别提高6.20%和7.78%。
To ascertain the effect of diethyl aminoethyl hexanoate and thidiazuron and their mixture on yield and quality of soybean,the agents with appropriate concentration were foliar sprayed at R1 stage of plant in the buckets.Kennong 18 was used as test variety.Spraying diethyl aminoethyl hexanoate,thidiazuron and their mixture were the treatment groups and spraying water was the control.Soybean yield,quality,dry matter accumulation and sucrose metabolism were measured after spraying.The results showed that diethyl aminoethyl hexanoate,thiadizuron and their mixture with a proper concentration effectively enhanced sucrose phosphate synthetase and sucrose synthetase activities,increased dry weight of leaves and sucrose content in leaves.The leaf dry weights were increased by 5.06%-22.85%,14.47%-28.50%and 1.45%-6.72%,respectively.Sucrose contents were increased by 9.94%-19.69%,11.92%-48.57%and 18.49%-118.26%,respectively.Among them,0.2 mg·L^(-1) thidiazuron and the mixture of 20 mg·L^(-1) diethyl aminoethyl hexanoate and 0.1 mg·L^(-1) thidiazuron increased the grain weight per plant by 19.10%and 19.16%.The combination of 60 mg·L^(-1) diethyl aminoethyl hexanoate with 0.6mg·L^(-1) thidiazuron was beneficial to quality improvement,which increased the protein and fat content by 6.20%and 7.78%,respectively.
