Abstract:
The experiment was conducted to investigate the effects of water and fertilizer coupling on yield,quality and leaf photosynthetic capacity of twelve-year-old trees of the middle-late mature cultivar ‘Chongyanghong’ peach before harvest.The results indicated that compared with CK,the yield per plant increased by 3.95%-49.72% after applying vermicompost,furthermore,the yield-increasing effect was optimal when the amount of vermicompost was 9 kg per plant.With the same amount of vermicompost,the treatments without irrigating paled in comparison with the effects of water and fertilizer coupling treatments on increasing yield,whilst the T4 treatment(vermicompost per plant 9 kg,irrigation amount per plant 30 L) had the highest yield.Applying vermicompost could improve the intrinsic quality to different degree.Especially,the T4 treatment could improve the mass fraction of soluble solid and the ratio of TSS significantly.The indicators mentioned above increased by 17.40% and 60.27% respectively compared with CK;applying vermicompost could also improve the leaf photosynthetic capacity before harvest,and the effect of T4 treatment was the best.Pn,Tr,Gs of the leaf were significantly higher than CK,of 1.33,1.30,1.56 times respectively than CK.Similarly,effects of water and fertilizer coupling treatments on Tr and Gs were better than which with the same amount of vermicompost but without irrigating obviously.From those statements,we could attain the conclusion that applying vermicompost could increase yield,quality and pre-harvest leaf photosynthetic capacity of ‘Chongyanghong’ peach.Among five treatments,the T4 treatment (vermicompost per plant 9 kg,irrigation amount per plant 30 L) was the best.
