Cultivation method of apocarya fruiting large container seedlings

Abstract

The invention discloses a cultivation method of apocarya fruiting large container seedlings, and belongs to the technical field of forest seedling cultivation. The method comprises the steps of medium-container seedling cultivation, large-container cultivation, preliminary tree form pruning, grafting and three-year cultivation for fruiting. The method is high in transplanting survival rate and rapid in seedling growth. During outplanting, the ground diameter can reach 3.5-4 cm, the seedling height is 2.5 m or above, the crown breadth is 4 m or above, and the sizes are remarkably higher than that of field cultivated seedlings of the same specification for orchard establishment. By using large-specification root control container pieces for seedling raising, a large number of fibrous roots are promoted in the growth process of seedling roots, and meanwhile, through two measures of transplanting seedlings into a middle container and then transplanting the seedlings into a large container,excessive growth of main roots is controlled through two times of root cutting treatment. The large-container seedlings cultivated by adopting the method for orchard establishment is high in plantingsurvival rate and remarkable in growth amount, fruits continue to be borne in the same year or the next year of planting, the effect of immediate orchard establishment is achieved, and the time fromorchard establishment to income acquisition is greatly shortened for planters.

Description

technical field [0001] The invention belongs to the technical field of forest tree seedling cultivation, and in particular relates to a method for cultivating large-container seedlings of hickory with thin shells. Background technique [0002] At present, the main seedling form of hickory nuts is still bare-rooted seedlings, and the survival rate of bare-rooted seedlings is low and the seedling period is long when the garden is built. If you want the orchard to enter the high-yielding period as soon as possible, you generally choose large trees that are 3-5 years old and have entered the fruit-bearing period. However, when raising seedlings in the nursery, the damage to the root system is more serious, and the impact on the survival rate of transplanting and the slow seedling period is greater. , it is difficult to achieve the goal of early fruit and high yield. Container seedlings are usually grafted for one year to build a garden. It takes at least 3-5 years to enter the ...

Problems solved by technology

[0009] Aiming at the problems existing in the prior art, the technical problem to be solved in the present invention is to provide a kind of cultivation method of hickory carya fruit-bearing large container seedlings, through steps such as container seedling cultivation, large container cultivation, preliminary tree shape pruning, after grafting Cultivate for 3 years to bear fruit, to solve the problem of long time to enter the fruiting period and slow income in the process of building a thin-shell hickory.
