Method for shortening orchard establishment time of Mongolian oak clone grafting seed orchard

Abstract

The invention relates to a wood breeding method, in particular to a method for shortening orchard establishment time of a Mongolian oak clone grafting seed orchard. Early spring indoor bare root grafting is adopted; after grafting bodies sprout and survive, the grafting bodies are transferred into a bottomless plastic container to be cultured; and when the outdoor temperature is appropriate, direct field planting and orchard establishment are performed, the orchard establishment time is shortened by one year compared with conventional orchard establishment time; during seedling carrying and transplantation, seedling roots are not damaged, the root system water loss is small, the field planting survival rate is high, the afforestation time can further be prolonged, transplantation can also be performed even if the seedlings expand leaves and grow, and the method is favorable for labor arrangement.

Description

technical field [0001] The invention relates to a method for establishing a tree clone seed orchard, in particular to a method for shortening the time for establishing a seed orchard for the grafted Quercus mongolica clone. [0002] technical background [0003] Traditional clonal grafting seed gardens generally adopt the method of planting rootstocks on the spot in the first year, grafting in the second year or cultivating grafted seedlings in the nursery in the first year, and planting in the second year. It takes at least two years to build a garden, and the rootstocks are fixed first and then planted in the second year. When grafting, it is not only inefficient but also easy to confuse the number when picking one plant to change the number. The nursery is used to cultivate grafted seedlings for planting and planting. Because the roots of the seedlings are not protected, the root soil is easily scattered during transportation, which seriously affects the survival rate of pl...
