摘　　要：采用大田调查、田间定位试验与室内化学分析相结合的方法,运用诊断与推荐施肥综合系统(DRIS),对高、低产组石榴叶片N、P、K、Ca养分分析数据进行不同表示式计算,初步筛选出N/P、N/K、N.Ca、K/P、Ca/P和Ca/K为DRIS诊断参数,并初步提出石榴DRIS诊断标准。通过对田间定位试验结果的营养诊断表明,DRIS适合新疆南部石榴的施肥诊断。Combining field investigation and plot trials with laboratory chemistry analysis, the expression calculation of analysis data of N, P, K and Ca in pomegranate leaves of high yield group （yield≥15000 kg/hm^2） and low yield group （yield 〈 15 000 kg/hm^2 ） were done according to DRIS. N/P, N/K, N · Ca, K/P, Ca/P and Ca/K were screened out for the DRIS parameters, and DRIS norms for foliar nutrient diagnosis of pomegranate were put forward. The field test results showed that DRIS was suited to the fertilization diagnosis for pomegranate in Southern area of Xinjiang.
