Investigation Of Hanfu Apple Production Status In Shenyang Region And Improvement Of Fruit Shape

In recent years,with the expansion cultivation area of Hanfu apple and the popularization of standard cultivation techniques,the present cultivation situation and fruit quality of the orchard are increasingly concerned to people.So we investigate some apple orchards of the Shenyang and surrounding areas to understand the current status of cultivation and fruit quality of apple orchard in Shenyang areas.In this study.6 typical demonstration apple orchards in Shenyang areas were investigated.The basic conditions,cultivation techniques,yield,ratio of high quality fruit and earning of the orchards were investigated through field investigation and consultation.And after harvest,the fruit quality was determined.Because of cold resistance,demonstration orchards are actively participated in related training to improve the ability of cultivation management,and using the new technology to the orchard production and management.The quality of the fruit is certain improved compared to the overall level of Shenyang.Nearly 3 years,the demonstration orchards is compared to the overall level of Shenyang.The fruit index was up 1.2%.The single fruit dropped 3.4%.The hardness increased by 1%.Soluble solids increased 1.9%.Soluble sugar increased by 3.9%.Results indicate that,with the use of new technology.the yield,fruit quality,ratio of high quality fruit and income of the orchards were significantly improved.But it is unexpected for prolong the carpopodium and fruit shape index of the apple.Therefore,this study is aimed to solve the problems that the short of fruit carpopodium length and fruit shape index of Hanfu apple.The 11 years old Hanfu/GM256/Malus Baccata Borkh.was used as the materials in this study.We study the effects of using different concentrations of GA3 and mixture before inflorescence separation on the growth of fruit carpopodium,as well as the effects of different concentrations of Promalin and mixture before inflorescence separation or after flowering on the fruit shape index,and compared by clear water.The results showed that the treatments of prolong fruit carpopodium could improve the growth of fruit carpopodium when comparing with the control.With the increase of GA3 concentration in this study,the effect was significant between different GA3 concentrations.After harvest,the length of fruit carpopodium which treated by 100-times GA3 reached the peak and was increased significantly(35.57 mm),and the contrast was shortest(26.13 mm).The fruit quality of each treatment was slightly different with the contrast,and it was not significantly.Compared with the contrast,all the treatments of improve fruit shape could improve the fruit shape index,and the difference was significantly.And the effect of 1200 times concentration and twice spraying of Promalin was the best.The fruit shape of high concentration were too large,and the improve effect of low concentration on the fruit shape were no significant.As the phonological,the fruit were growing constantly,the fruit shape index of the treatments and contrast were decreased.Because of the increase of the fruit vertical diameter,the fruit shape index of the treatments were enhanced.There was no significant difference between the fruit quality of treatments and contrast.
