| Abstract: | 4 years old Psidium guajava were used as the test material, and 4 tree structure types （open center shape, round head shape, flat shape） were used and compared with natural circular tree structure in fruit production to research the effect of four kinds of method on trees＇sprouts, buds, flowering and fruiting. The experimental results show that the round head shape and open center shape are good for the myrtle＇s flowering and fruiting, round head shape is helpful to improve the myrtle＇s output. |
