Effects of crop rotation and organic fertilizer application on the growth,fruit quali-ty and yield of pineapple
Field experiment was conducted to investigate the effects of crop rotation and organic fertilizer appli-cation on pineapple growth,fruit quality,and yield.The results showed that compared with pineapple contin-uous cropping(PP)treatment,pineapple continuous cropping with bio-organic fertilizer(PPB),pineapple-sugarcane rotation(PS)and pineapple-sugarcane rotation with bio-organic fertilizer(PSB)treatments signifi-cantly improved the growth,yield,and fruit quality of pineapple.On plant growth,PPB,PS and PSB treat-ments had a significant enhancing effect on leaf length,leaf width and leaf number.On fruit appearance,the vertical diameter,horizontal diameter,number of fruit eyes,flesh thickness and the ratio of flesh thickness to heart diameter of PPB,PS and PSB treated pineapple were significantly increased,while the height of the top bud and the diameter of the fruit heart were significantly decrease.On fruit quality,the content of soluble sol-ids,vitamin C and soluble sugars of PPB,PS and PSB treated pineapple were significantly increased,while the content of titratable acid was significantly decreased.On yield,the average single fruit weight of PPB,PS and PSB treated pineapple was significantly increased by 32.61%,51.09%and 71.74%,respectively,compared with PP treatment,and the total yield was significantly increased by 14.74%,34.58%and 48.28%,respec-tively.In addition,the yield,fruit traits,and quality indicators of PSB treatment were significantly higher than those of PPB treatment,and better than those of PS treatment.It is suggested that in the local pineapple production,bio-organic fertilizer can be properly applied on the basis of pineapple-sugarcane rotation.
