首先,考虑调理剂的材料特点。如果是天然资源调理剂,施用量可以大一些,而且适宜用量的范围较宽;而人工合成的调理剂,因效能和成本均较高,则用量要少得多。其次,考虑调理剂的施用条件。土壤条件对调理剂的施用效果影响较大。土壤墒情影响调理剂散布均匀性,土壤含水量过高,耕性较差,田间操作困难,而且难以混拌均匀;土壤质地影响调理 First, consider the material characteristics of conditioner. In the case of a natural resource conditioner, the application amount may be larger and the suitable range of the amount to be used may be wider; and the synthetic agent may be used in a much lower dosage because of its higher efficacy and cost. Second, consider conditioning conditions. Soil conditions on the application of conditioning agents have a greater impact. Soil moisture affects the uniformity of soil conditioner distribution, soil moisture is too high, poor tillage, difficult field operation, and difficult to mix evenly; soil texture conditioning
