苎麻肥料累积效应试验研究

Preliminary report on fertilizer accumulate effects experimentation of Ramie

通过两个苎麻试验结果分析,表明试验1在三年等量差异施肥试验中,第三年纤维产量出现高肥中产和中肥高产现象,即高肥区出现肥料“累积效应”,中肥区施肥量比较“适中”,而低肥区则处于“饥饿”状况,试验2在三年不等量差异施肥试验中,没有出现上述现象;又根据投入产出比分析,试验2比试验1肥料利用率更高;分析各处理碱解氮和速效钾,均同样证明存在肥料“累积效应”现象。

The results showed that there were ＂fertilizer accumulate effects＂ in high level fertilize area of the experimentation of three - years equality quantity different fertilizer , and there were ＂hungry＂ estate in the low level fertilize area. But there were not this electrophoresis in the experimentation of three - years blame equality quantity different fertilizer. Bases compared the devotion with the output again , the results proved that ＂fertilizer accumulate effects＂ were exist.
