In order to enhance the accuracy ,reliability and comparability of the laboratory testing results ,using the quartile robust statistical and principal component ,the nitrogen ,phosphorus ,potassium and chloride ion in compound fertilizer were analyzed in Linyi .The results showed that the testing results of nitrogen and phos-phorus were satisfied by each laboratory ;all the fertilizer companies were satisfied with the results except one company was not satisfied with the measurement results of potassium ;The chloride ions were satisfying by six companies ,the results were doubtful in one company ,and two companies did not meet the request .Results also showed that the detection ability exhibited different in the order was L 7> L2> L8> L3> L1> L6> L5>L4>L9 .
