马铃薯应用外源激素及叶面微肥的增产效果

为了探索马铃薯应用外源激素及叶面微肥的增产效果,选取农户普遍应用的马铃薯块茎膨大剂6种,新面世的产品3种,加对照共10个处理,进行小区试验。经方差和效益分析表明:欧罗壮叶面肥较对照增产13.0%,增加纯效益2 289元.hm-2,投入产出比1:16.9;狮王花宝叶面肥增产11.7%,增加效益2 123元.hm-2,投入产出比1:17;凯普克增产10.3%,增加效益1 791元.hm-2,投入产出比1:12.4;三禾绿丰增产6.1%,增加效益1 058元.hm-2,投入产出比1:9.6;金农富增产3.2%,增加效益497元.hm-2,投入产出比1:4.7。其它产品增产不明显,有些产品出现减产现象,在生产上应小心选用。

Effect of Exogenous Hormone and Microelement Foliage Fertilizer on Yield and Net Profit in Potato

Ten treatments,including 6 popular used tuber bulking induction agents,3 new products and 1 control,were applied to potato in this research,with the aim to understand their effects on potato morphology,total and marketable tuber yield,and importantly net profit.The experiment was grown in a Randomized Complete Block design with three replicates of each treatment,and analyses of variance and net profit were adopted for analyzing the data obtained.Compared with the control,Ouluozhuang increased tuber yield by 13.0% and net profit by 2 289 RMB·hm-2,and investment to output ratio was 1:16.9.For Shiwanghuabao,the yield increase was 11.7%,net profit 2 123 RMB·hm-2,and investment to output ratio 1:17.For other three products,Kalpak,Sanhelufeng,and Jinnongfu,the yield increase was,respectively,10.3%,6.1%,and 3.2%,net profit,1 791 RMB·hm-2,1 058 RMB·hm-2,and 497 RMB·hm-2,and investment to output ratio,1:12.4,1:9.6,and 1: 4.7.Other products had not apparent effect on yield,or even decreased yield.So,when considering using microelement foliage fertilizer in potato production,care must be taken to make a rihgt decision.
