Effects of Different Fertilization Treatments on Growth,Yield and Quality of Guava
摘要
Abstract
In order to explore the effects of different fertilization treatments on the growth,yield and fruit quality of guava,no fertilization(CK),single application of organic fertilizer 15 kg/plant(T1),conventional application of compound fertilizer 2 kg/plant(T2),organic fertilizer 15 kg/plant+compound fertilizer 1.6 kg/plant(T3),organic fertilizer 15 kg/plant+compound fertilizer 1.2 kg/plant(T4)and organic fertilizer 15 kg/plant+compound fertilizer 0.8 kg/plant(T5)were set up.The results showed that the branch length of T3 increased by 15.75%compared with T2,the longitudinal diameter of the two batches of fruits increased by 7.73%and 7.49%compared to T2,and the transverse diameter increased by 9.57%and 9.97%.The average single fruit mass of two batches of fruits treated with T3 increased by 18.80%and 21.36%compared to T2.The T3 and T4 had a better effect on improving fruit quality.Among them,the vitamin C content of the two batches of fruits treated with T3 increased by 19.98%and 10.80%compared to T2 treatment,and the soluble solids content increased by 19.61%and 11.30%.The total sugar content of two batches of fruits treated with T4 increased by 25.97%and 27.18%compared to T2,the reducing sugar content increased by 27.24%and 36.27%,and the crude fiber content decreased by 24.19%and 24.43%.To sum up,compared with the treatment of no fertilization or single fertilization,increasing the application of organic fertilizer by 15 kg and adding 1.2-1.6 kg of compound fertilizer per plant have a more significant promotion effect on improving the yield and quality of guava.关键词
