Unverified发热包分'生石灰型'和'无钙型'，生石灰型发热快但残渣需妥善处理且遇水后包体膨胀发烫，户外携带优选无钙型（碳酸钙/铝粉配方），发热更平稳且残渣可降解74% similarUnverified草木灰忌与氮肥（尿素、硫酸铵）和磷肥（过磷酸钙）混用：碱性会促使铵态氮挥发损失、使磷固定失效，两者需间隔7-10天分开施用71% similarUnverified碱性土（pH>7.5）降碱首选硫磺粉，用量约100-200g/㎡可降0.5-1个pH单位，需土壤微生物氧化，夏季高温期见效更快（1-2个月）71% similarUnverified海藻肥pH多呈弱碱性，不宜与酸性肥料（如硫酸亚铁、磷酸二氢钾）同时混用，会发生沉淀或降低效果，需间隔3-5天分开施用71% similarUnverified石灰粉不可与氮肥（尿素、硫酸铵）、磷肥同时混施，碱性会导致氮素挥发流失、磷素固定失效，需间隔7-10天分开施用70% similar
