摘要:

为了科学指导中国的桃测土施钾,采用“零散实验数据整合法”和“养分平衡—地力差减法”新应用公式,开展了中国桃土壤速效钾丰缺指标与适宜施钾量研究。结果表明:中国桃土壤速效钾第1~5级指标依次为≥312、170~312、92~170、50~92、<50 mg/kg。当桃的目标产量为15~60 t/hm2、钾肥利用率为50%时,桃土壤速效钾第1~5级的适宜施钾量范围依次为0~0、19~76、38~151、57~227、76~302 kg/hm2。本研究初步建立了中国桃土壤速效钾丰缺指标推荐施肥系统,为中国桃测土施钾提供了相应的科学依据。

Abstract:

To provide guidance for soil potassium application in peach planting, the new application formulas of “scattered experimental data integration method” and “nutrient balance-soil fertility difference subtraction method” were used to study the index of soil available K abundance-deficiency and the appropriate rates of potassium application in peach planting in China. The results showed that soil available K index in peach planting could be divided into 5 levels, which were ≥312, 170-312, 92-170, 50-92 and <50 mg/kg, respectively, from level 1 to 5. When the target yield of peach was 15-60 t/hm2 and the utilization rate of potassium was 50%, the suitable application rate of available K for level 1 to 5 was 0-0, 19-76, 38-151, 57-227 and 76-302 kg/hm2, respectively. In this study, the recommended fertilization system of available K according to its abundance-deficiency index in peach planting soil in China was established and a corresponding basis was provided for soil testing and potassium application.
