1、草木灰中含有多种钾盐,其中以碳酸钾为主,其次是硫酸钾及少量的氯化钾,属于生理碱性肥料,所以,草木灰不能与铵态氮肥混合施用,也不能与人粪尿、圈肥等有机肥料混合,以防氮素挥发损失。为提高草木灰的肥效,应进行单积单攒,单独施用。2、草木灰所含的钾盐90%以上可溶于水,为速效性钾肥。根据这一特性,草木灰可作基肥、种肥和追肥,其水溶液也可用于根外追肥。在水田中草木灰可用于水稻秧田的盖肥,起到供应秧苗
1, ash contains a variety of potassium, potassium carbonate-based, followed by a small amount of potassium sulfate and potassium chloride, is a physiological alkaline fertilizer, therefore, ash can not be mixed with ammonium nitrogen fertilizer application, nor with human excrement Urine, loop fertilizer and other organic fertilizer mixed to prevent loss of nitrogen volatilization. In order to improve the efficiency of ash, should be single-save, separate application. 2, Ash contained more than 90% of potassium soluble in water, as fast-acting potash. According to this feature, ash can be used as a base fertilizer, fertilizer and fertilizer, the aqueous solution can also be used for root top dressing. In the paddy field ash can be used in rice seedling fertilizer, play to supply seedlings
