The same interest in composting exists in Third-World countries, but in these areas windrow systems are the preferred method. 第三世界国家对堆肥同样很感兴趣,但在这些领域中,堆肥系统是他们的首选方法。
Sludge composting systems can be classified as windrow composting, aerated static piles and in-vessel composting. 目前常用的污泥堆肥化系统可以划分为:条垛系统,强制通风静态垛系统和发酵槽系统。
Its field trial showed that the free grain loss is reduced and specially invented windrowing device closely behind the stripping rotor located justified itself by the clear cutting with shorter stubble and being center delivered windrow of the straw. 田间试验表明落粒损失减少,作者发明的设置于摘脱流通筒后面的切割搂集装置工作性能良好:割茬低条铺放在两履带之间。
Three kinds of composting systems ( the windrow system, the aerated static pile system and the paked pile system) and their advantages and disadvantages were reviewed in this paper. 本文综述了现有的三种堆肥化系统:条垛式系统、通气静态垛式系统和发酵仓式系统,介绍了三种系统的优缺点。
And for the secondary fermentation, windrow composting was adopted, with the pile turned up periodically. This stage lasted for 30 days. 二次发酵采用定期翻堆自然腐熟,周期30d。
In situation of windrow composting, total nitrogen content in compost changed in trend of decrease with composting process, while total phosphorus, potassium and heavy metals content accumulated. 条垛堆肥条件下,随堆肥进程全氮含量呈降低趋势,磷、钾及重金属出现累积。
