Detailed Explanation of the Key Operational Points of Top Grafting Technology for Jujube Trees
Due to variation arising from long-term cultivation of varieties, the quality of jujube trees currently planted in various regions differs considerably. In the case of the golden silk jujube (Ziziphus jujuba 'Jinsixiaozao'), there are dozens of phenotypes in Jinghai, Tianjin alone, and the size and shape of their fruit vary greatly; determination of their contents has shown that the differences are also considerable. The harvested jujube products have poor uniformity in appearance. This greatly lowers their commercial price and reduces farmers' economic income.
To effectively solve this problem and make the fruit of the same jujube orchard uniform and consistent in appearance, top grafting is often used in current production, grafting 1-2 jujube varieties of better quality onto jujube trees that originally differed considerably in quality.
