Study on the effects of different sealing materials for adult grafting of kiwifruit
This trial was designed to find out the suitable sealing materials for the adult grafting of kiwifruit.Four sealing materials were used for 7-year'Jintao'grafting,on which'Donghong'was grafted.Survival rate,trunk and branch diameter,and the next year yield was measured and analized.Acrylic resin treatment had the lowest survival rate,which was only 35.00%,and it had the extremely remarkable difference compared to the other treatments.Whereas the survial rate of emulsified asphalt,grafting wax and grafting film treatment seperately was 68.33%,71.67%,78.33%,and there was no significant difference among them.At the same time,growth vigour of the survival vines of the 4 treatments was equal,and there was no significant difference among them on trunk and branch diameter and fruiting cane number of each branch.As to the fruit amount of each survival vine,acrylic resin treatment had the lowest amount,grafting wax treatment had the highest,and it had remarkable difference between them;grafting wax and grafting film treatment had bigger single fruit weight;acrylic resin treatment had the lowest yield per vine,and it had remarkable difference compared to the other treatments.
