摘　　要：开展1.8%复硝酚钠水剂调节番茄生长田间药效评价。试验结果表明,在番茄苗期、花蕾期和幼果期喷施1.8%复硝酚钠水剂3 mg·kg^(-1)、6 mg·kg^(-1)、9 mg·kg^(-1)三次,番茄叶色浓绿,生长势好,3mg·kg^(-1)、6 mg·kg^(-1)、9 mg·kg^(-1)处理比0 mg·kg^(-1)对照株高分别增加6 cm、9 cm、11 cm,单株绿叶数分别增加1片、1片和3片,茎基粗分别增加0.1 cm、0.3 cm、0.4 cm,座果率提高3.35%、4.53%和6.1%。可溶性固形物、可溶性总糖、Vc均比对照高,可滴定酸基本持平。果实圆润,色泽较好,3 mg·kg^(-1)、6 mg·kg^(-1)、9 mg·kg^(-1)处理比0 mg·kg^(-1)对照产量分别增加161.7 kg、395.6 kg和578.4 kg,提高1.32%、3.22%和4.71%。Field efficacy evaluation of sodium nitrophenolate 1.8%for regulating tomato growth was conducted.The results showed that after the spraying with 1.8%sodium nitrophenolate 3 mg·kg^(-1),6mg·kg^(-1),9 mg·kg^(-1) three times,the tomato leaves were dark green and the growth potential was good at seedling,flower bud and young fruit stages.Compared with the 0mg·kg^(-1) control,the plant height under treatments of 3 mg·kg^(-1),6 mg·kg^(-1) and 9 mg·kg^(-1) increased by 6cm,9cm,11cm,the number of green leaves per plant increased by 1,1,and 3,and the base thickness of the stem increased by 0.1cm,0.3cm,0.4cm,the fruit-setting rate increased by 3.35%,4.53%and 6.1%,respectively,The soluble solids,total soluble sugar,and Vc were higher than the control,and the titratable acid was basically the same.The fruit was round and the color was better.Compared with the 0mg·kg^(-1) control,the yield under the 3 mg·kg^(-1),6 mg·kg^(-1) and 9 mg·kg^(-1) treatments increased by 161.7 kg,395.6 kg and 578.4 kg respectively,and increased by 1.32%,3.22%and 4.71%,respectively.
