Effects of Different Planting Density and Row Space on Yield and Quality of Banana
In order to determine the planting density and row spacing configuration suitable for mechanized cul-tivation of banana,a split-plot experimental design was used with planting density(P,P1:2,190 plants· hm-2,P2:2,340 plants·hm-2,P3:2,520 plants·hm-2)as main plot,and the row space(R,R1:5.10 m wide row and 1.00 m narrow row;R2:4.80 m wide row and 1.30 m narrow row;R3:4.50 m wide row and 1.60 m narrow row)as split plot.The effects of different planting density and row spacing configuration on agronomic traits,yield and quality of banana were measured.The results showed that R could significantly affect the plant height and stem circumference of banana.P and R had significant effects on yield per plant and total yield of banana.The yield per plant of P1 and P2 was significantly higher than that of P3 by 10.29%and 10.88%,respectively,and the total yield of P2 was signifi-cantly higher than that of P1 by 6.62%.R3 had the highest yields of per plant and total yield,and R1 had the lowest yields of per plant and total yield.Analysis of the yield composition indicated that R3 can improve the commercial harvest rate of banana.Single fruit weights of P1 and P2 were significantly higher than that of P3,and the single fruit weight of R3 was sig-nificantly higher than that of R1 and R2 by 21.23%and 4.44%,respectively.The fruit finger length of P1 was significantly higher than that of P3,and the fruit finger length and fruit finger circumference of R2 and R3 were significantly higher than those of R1.P and R had no significant effect on fruit soluble solids.The titratable acid content of P3 was significantly higher than that of P1 and P2,and contents of the vitamin C of P1 and P2 were significantly higher than that of P3 by 19.38%and 15.78%,respectively.R3 significantly increased vitamin C content by 8.77%compared with R1.In summary,when the planting density of Baodao banana was 2,340 plants/hm2,and the wide row was 4.50 m and the narrow row was 1.60 m,the agronomic traits,yield,commercial harvest rate,single fruit weight,soluble solids and vitamin C contents of banana were the highest.
