The storage of apple scion is essential for the propagation and cultivation of fruit trees. Proper storage methods can ensure the activity of the scion and improve the survival rate of graftingConversely, it may lead to scion wilting and loss to the grower. This article will introduce the storage method of apple scion in detail, including three links: collection, processing and storage.
First, the collection of scion.
The harvesting time for apple scion is usually carried out after the leaves have fallen in autumn and before bud break in spring. At this time, the branches are full of nutrients and strong vitality, which is conducive to grafting and survival. When collecting, the mother tree with good varieties, healthy and free of diseases and pests should be selected, and the annual and full branches should be selected as the scion. Harvested scion should remove the leaves and leave only the petioles to reduce water evaporation and nutrient depletion. Professional seedling companies have special scion nurseries, which can fully guarantee the purity of scion. The collection tools should also be disinfected at the time of collection.
Second, the treatment of scion.
Harvested scion needs to be properly handled before it can be stored. First of all, the scion should be classified and sorted according to thickness and length for subsequent operations. At the same time, attention should be paid to prevent the scion from being damaged by frost damage or high temperature. Secondly, the wax sealing treatment is carried out to prevent the loss of moisture. Third, it is necessary to carry out anti-water loss and mildew prevention treatment.
3. Storage of scion.
The storage method of apple scion is directly related to its service life and grafting effect. There are many kinds of storage methods, but for professional seedling companies, they are all stored in a constant temperature warehouse, and the humidity and temperature can be well controlled. The quality of the scion can be guaranteed.
In conclusion, the storage method of apple scion is essential for the propagation and cultivation of fruit trees. Only by mastering the correct storage method can we ensure the activity of the scion and improve the survival rate of grafting.
