草木灰是很好的肥料,除含碳氢氮以外,还含有农作物所需要的灰分元素,以钾为主,兼有磷、钙和微量元素等营养物质.草木灰具有质轻、碱性和易溶等特性.在积攒上应注意:①防止风吹雨淋,应设灰仓或灰棚贮存.②草木灰质轻易飞,施用困难,最好混拌肥土1～2倍,保持湿润,肥分可被土吸收而保存起来.③草木灰最忌放入沤肥坑沤泡,以免水溶性养分被浸出淋失.④草木灰不能和人粪尿、牲畜粪尿和氮素化肥混合,因具有碱性,混合后会使粪中氮素(氨气)跑掉,降低肥效.⑤草木
Ash is a very good fertilizer, in addition to nitrogen and nitrogen, but also contains the ash needed for crops, mainly potassium, both phosphorus, calcium and trace elements and other nutrients. Ash with a light, alkaline and soluble Etc.
