Chestnut high-replacement technology
In the past, many chestnut seedlings were used in chestnut, and the varieties were mixed. The tree species were tall, the results were late, the yield was low, the size was very serious, and even a large number of chestnut trees did not produce fruit, or the results were few, and the empty rate was high. For such chestnut cultivars, the selection of superior cultivars for high-yielding varieties can make full use of the robustness of the trunks of the chestnut trees and the characteristics of the developed root systems, resulting in higher yields in a shorter period of time.

1. Choosing the appropriate scion for the selection of suitable varieties requires strong grafting affinity. Such as Yangshan oil chestnut can choose Agricultural University 1, double season chestnut and so on. The structure of the tree is compact and there are many female flowers. The result is early, the quality is good, and the yield is high and stable. At the same time, it is best to choose a good variety with similar flowering duration, allocate a certain amount as a pollination tree, or graft 2-3 fine varieties together, and configure an appropriate number of pollination branches on the large anvil to increase the fruit setting rate and seed setting rate.
2. The grafted parts of the chestnut tree can be changed from several years to several decades, but it is better not to exceed 20 years. Graft sites can have the following options:
2.1 The main branches and sub-branches have multiple long stems and the main stems and sub-branches are evenly distributed. When the main branches and sub-candles are evenly distributed, they are grafted on the main branches and vice main branches. The advantage is that it is easy to operate and canopy culture is easy, but the new canopy formed is still high.
