摘要： 以冬小麦为供试作物，采用肥力中等的红油土进行盆栽试验，对试制的含有N、P、K、Zn、Fe5种元素的四种草炭复混肥制品（酸化处理、加水处理、干混处理、肥料混合物）进行了肥效试验。结果表明：草炭复混肥制品均明显的提高了小麦生物学产量，增加了根系干重；减少了土壤对Zn、Fe、P的固定作用，作物吸收养分量增多。在4种复混肥中酸化处理的效果最为明显，加水处理次之。不同施肥方法对复混肥效果有一定影响，分层施用优于混施。

Abstract: In this paper, four types of peat-compound fertilizers were made, which mainly contained five elements of N, P, K, Zn and Fe. Pot experiment of fertilizer effect was conducted by using winter wheat as test crop and red oil soil as test soil. The results showed that all the peat-compound fertilizers significantly increased the biomass and dry root of winter wheat. The fixing effect of soil on Zn, Fe, and P was attenuated and the uptake amounts of the elements were increased. Among the fertilizers, acidizing had the best effect, and the treatment of adding water was next to it. As for fertilizer application methods, layering application was better than mixing application.
