引言二十世纪六十年代中期以来,酸性矿质土壤的石灰建议用量一直根据Mohr(1960),Cate(1965)和Kamprath(1970)所报导的公式来估算的:毫克当量Ca/100克土=1.5毫克当量交换性A1/100克土。它比根据要求达到某一pH值来估算石灰
INTRODUCTION The recommended lime dosage for acidic mineral soils since the mid-1960s has been estimated using the formula reported by Mohr (1960), Cate (1965), and Kamprath (1970): Me basis of Ca / 100 g soil = 1.5 Milligrams equivalent exchangeable A1 / 100 grams of soil. It estimates the lime more than a certain pH on demand
