The advantage of apple tree grafting is that it can maintain the excellent characters of varieties and blossom and bear fruit early. As a result, the seedlings cultivated by the branches and buds on the tree can blossom and bear fruit early. Enhance the resilience of fruit trees, and improve the yield and quality.
The suitable grafting period of apple trees is from late March to early April, and the budding period is from late June to early September. 1988.6 TV buds grafted before mid-June can germinate in the same year, but cannot germinate after August.
Extended data:
Early bud thinning of apple trees can save nutrition, help to bear large fruits and promote fruit accumulation. At the same time, strengthen the tree potential, promote the growth of spring shoots and make up for the lack of pruning in winter. It can save working hours, improve efficiency and reduce costs.
In normal climate, the technology of "bearing fruit with flowers" can be popularized. That is, in the middle and late April, when the inflorescence is red until the inflorescence is separated (the central flower appears bud), the two sides and the lower part of the mother branch are mainly selected according to the flower cluster spacing of 20-28 cm, and all the redundant flowers are thinned except the central flower and 1 lateral flower, but the "cluster leaves" must be reserved.
According to the target yield, if there are too many flowers, trees entering the fruiting stage can cut short some medium-long flower branches, shrink and cut off weak short flower branches, so as to reduce flower branches and increase backup branches.
