Investigation on the effect of applying LTPF bacterial agent on sweet cherry Hongdeng
Using conventional fertilization as a control,one-time autumn fertilization was con-ducted for two consecutive years in 2019 and 2020,to study the effects of different doses of LTPF bacterial agent on the growth and development,fruit quality,and yield of Hongdeng.The results showed that when the application amount was 2.5～15 kg per plant,the yield and quality of Hong-deng increased with the increase of application amount.Comprehensive consideration,the dosage of 10 kg per plant was appropriate.The proportion of healthy flowers increased from 60.0%to 99.0%,the proportion of aborted flowers dropped from 16%to 0%,the proportion of double-stig-ma flowers dropped from 23.5%to 1.05%;the shrink disease fruit rate dropped from 20.7%to 0%,the fruit cracking rate dropped from 32.7%to 4.3%;the soluble solid content of the fruit in-creased from 8.5%to 12.0%;the yield per plant increased from 11.5 kg to 28.5 kg,an increase of nearly 2.5 times;the number of glue points on the branches of a single plant reduced from 26 to 0,and the bark changes from extremely rough to smooth.The effect of improving quality,increasing yield and healthy trees is remarkable.
