To make blueberries grow more robust and to improve blueberry yield and quality. Blueberries are usually grafted onto the Oryza sativa tree for the following reasons:

1. Because the Oryza sativa tree has a particularly well-developed root system with a well-developed deep-rooted taproot and a large number of fibrous roots, it has a very strong absorptive capacity, which allows the blueberry scion to grow more robustly.

2, due to the blueberry fruiting characteristics are usually in an age of the branch development of fruiting branches, through the grafting of a number of branches on the Uyeni tree or a large number of scions grafted on a branch to achieve a large number of fruiting branches appear in the year to achieve early yield. At the same time, it is also possible to have multiple varieties on one tree to achieve the purpose of cross-pollination to improve the quality of the fruit.
