Effects of Different N, P and K Combination on Yield and Quality of Pitaya
The "3414" test was used to study the effects of N, P and K combination on yield and quality of pitaya to provide the scientific basis for rational application in pitaya production. The results showed that the tested different N, P and K combinations all improved yield of pitaya significantly, but there was no significant difference in yield between Treatment 15 (the convention application plot and Treatment 9 (the highest yield in the "3414" test). Different N, P and K combination had different effects on soluble solids, total sugar, total acid and mineral elements of pitaya fruit, but the N, P and K content in pitaya fruit didn't increased with increment of N, P and K application, which may be closely related to growth characteristics and nutrient distribution and demand of pitaya.
