【摘要】 为探索新型植物生长调节剂“多果宝”在柑桔上的应用效应 ,采用小区验证试验和大面积生产试验相结合的方法 ,进行较全面、系统的观察研究。结果表明喷施多果宝具有以下效应 :(1)能减少落果 ,提高产量 ,比对照增产 2 0 .2 9%以上 ;(2 )能改善果实外观与内质 ,单果重比对照及喷施赤霉素分别提高 10 .8g及 11.6g ;(3)能促进叶片生长发育 ,增加叶片厚度、重量 ,提高叶片叶绿素含量 ;(4)经济效益显著 ,产投比达 2 3.0 6∶1。综上结果表明 ,多果宝是一种新型实用的保果壮果药剂 ,在柑桔生产上具有推广应用价值更多还原

【Abstract】 The application effects of new type plant growth regulator “duoguobao” was studied by means of plot testing and large-scale productional experimentation. The results show that “duoguobao” can (1) decrease markedly fruit abscission, increase fruit yield by 20.29% more than that of the CK; (2) improve markedly the outward appearance and intrinsic quality of fruit, increase weight of per fruit by 10.8g more than that of the CK and 11.6g more than that treated with GA 3; (3) promote the development of the leaf, increase leaf thickness, weight and chlorophyll content; (4) increase markedly economic benefit, with an output/ input rate of 23.06∶1. The results of this study show that “duoguobao” is a new type of regulator, which is practical for protecting and swelling fruit and worth popularization and application in citrus production.更多还原
