What are the grafting techniques for peach seedlings in spring?
Peach tree is one of the key planting projects in the social and economic development of plantations in China, and its types are very diverse. Peaches and peaches are generally popular in the sales market. With the great market prospect of peach trees and the continuously rising prices, peach trees are more and more warmly welcomed by growers. In order to ensure the quality of peach planting, peach seedling grafting technology is well known and used in the whole process of production and planting. Now the grafting method of peach seedlings is shared with everyone.
1. Peach trees can actually be grafted all the year round, but generally speaking, peach trees have a higher survival rate in spring and summer. Among them, the best time for spring grafting is from mid-February to mid-late April; in summer, grafting is from mid-May to early August; autumn is usually carried out from the end of July to the end of September; and winter is from the beginning of October to the middle and late January of next year. It is suggested that everyone should choose the suitable grafting time according to their own specific planting requirements, so that the passing rate of peach grafting can be improved.
2. Prepare ① rootstocks for grafting in advance: not all seedlings can be used to graft peach trees, and rootstocks that can be grafted peach trees do not necessarily have that high survival rate. Therefore, people must choose the best rootstock, generally choose different kinds of peach seedlings is the best. ② scion selection: it is best to choose one-year-old, strong, disease-free, resistant, improved peach branches. ③ grafting tools are prepared in advance: common grafting tools are prepared in advance, the key includes plastic film and so on.
3. When the grafting method is used specifically, because it will choose rootstocks and scions of different sizes, the grafting method of peach trees is not single limited, and the actual methods that must be grasped should also be different. otherwise, it will immediately endanger the survival rate of peach grafting. Generally, the most common methods are bud grafting and branch grafting, while bud grafting includes T-shaped bud grafting and embedded grafting, and branch grafting includes split grafting and web grafting. In the whole process of grafting, we should not only manipulate the deep layer of grafting, but also make the rootstock match with the scion, so that the healing ability of grafting can be improved, and then the survival rate of grafting can be improved. After grafting the rootstock and scion, the binding must be carried out with plastic film, which can prevent the rootstock and scion from being harmed by gas and water, and reduce the healing ability, resulting in unsuccessful grafting.
4. if the management method after grafting is successful, buds will generally grow in about 15 days. During this period, it is necessary to carefully observe the growth and development of green seedlings and remove the buds that have not been completely eliminated. In addition, after successful grafting, the bound plastic film must be untied, and after a period of growth and development, appropriate pest prevention and fertilization can enter a new link of growth and development.
To sum up, grafting is the most common way of breeding peach seedlings, such as hairy peach, nectarine, pan peach and other different kinds of peach trees are more suitable for peach grafting trees. Do a good job in the preparation before grafting, and select a suitable grafting method according to the grafting standard to prevent endangering the passing rate of grafting.
