Effects of Different Fertilizers on the Fruit Yield and Quality of Pitaya
Three-year-old'Big Red'pitaya plants were used as test materials to compare the effects of five fertilizers,in-cluding amino acid,fish protein,alginate,xanthic acid,and chemical balance fertilizer,on the fruit yield and quality of pitaya plants to provide a basis for its application in practical production.The results showed that amino acid,fish protein,and algi-nate significantly improved the fruit weight,fruit size,and yield of pitaya,among which those of alginate increased by 15.61%,30.52%,and 30.90%,respectively,compared with those of CK;the distribution of sepal greenness among treatments did not significantly differ,but all of them improved the sepal greenness;different treatments significantly improved the fruit sensory score,among which fertilizer application of fish protein showed the best performance in terms of taste and flavor,which in-creased by 11.67%,19.58%,27.79%,33.93%,and 50.54%,respectively,compared with that of CK at different storage periods(0,3,5,7,10 d);and the sensory scores decreased continuously with storage time,decreasing rapidly from the 3rd to the 5th day and then decreasing slowly.However,the effects of each treatment on the intrinsic quality of fruit,such as soluble solids,edibility,peel thickness,and shelf life,were not significant.However,they all enhanced the soluble solids in the center and edges of the fruit and reduced the peel thickness to different degrees.The effects of various treatments on the fruit quality of pitaya varied,and the greatest effect of fish protein was evaluated comprehensively.In actual production,fish protein can be used or mixed with other fertilizers,and the effect may be better.
