Description
Technical field
The present invention relates to planting fruit trees technical field, a kind of method for cultivating citrus seedling more particularly, to lemon stock.
Background technique
Rutaceae Aurantioideae is distributed between 16 ° -37 ° of north latitude.It is tropical, subtropical evergreen fruit trees (in addition to trifoliate orange),
There are 3 categories: Poncirus, Citrus and Fortunella as Economical cultivation.The method of citrus seedling propagation mainly has at present: grafting,
Cuttage is grown directly from seeds, press strip etc..Wherein mainly based on grafting, propagation by grafiting can be ahead of time as a result, be able to maintain the high-quality spy of kind again
Property.Stock is the basis of fruit-tree grafting seedling, and stock can be whole strain fruit tree, is also possible to the root segment or branch section of tree body, fixation,
It supports scion and forms plant strain growth, result after healing with scion.
The breeding method of traditional citrus seedling is the full ripe fruit of harvesting, takes out cultivating seeds to spring in next year and grows directly from seeds
Seedling.It is grafted in time when next year spring is suitble to grafting to autumn or again when seedling growth, starts to cultivate grafting, when the method
Between it is longer, it is time-consuming.
