Embodiment 1

[0030] A kind of grafting method of hickory nut with thin shell, concrete steps comprise:

[0031] 1. Build a potted ear garden

[0032] Use excellent varieties or excellent mother tree spikes as materials to propagate high-quality seedlings and build potted ear picking gardens.

[0033] Because pecan is a deep-rooted tree species, the seedling container can be cylindrical or cuboid. The bottom diameter of the container is 40 cm and the container depth is 60 cm. A polyethylene root-controlling rapid seedling container is selected. The seedling substrate is organic nutrient soil. The management of potted ear gardens can refer to the general ear garden management methods.

[0034] 2. Rootstock cultivation

[0035] Use high-quality seeds for sand bed stratification to accelerate germination, cultivate high-quality sprouts, cut roots and transplant them into containers, and cultivate high-quality rootstocks.

[0036] Thin-shelled hickory seeds were treated with moisture absorp...

Embodiment 2

[0043] A kind of grafting method of thin-shell hickory nut, concrete steps comprise:

[0044] 1. Build a potted ear garden

[0045]Use excellent varieties or excellent mother tree spikes as materials to propagate high-quality seedlings and build potted ear picking gardens.

[0046] Because the thin shell hickory is a deep-rooted tree species, the seedling raising container can be cylindrical or cuboid, with a bottom diameter of 60 cm and a container depth of 80 cm, and an antiseptic wooden container is selected. The seedling substrate is organic nutrient soil. The management of potted ear picking gardens can refer to general ear picking gardens.

[0047] 2. Rootstock cultivation

[0048] Use high-quality seeds for sand bed stratification to accelerate germination, cultivate high-quality sprouts, cut roots and transplant them into containers, and cultivate high-quality rootstocks.

[0049] Thin-shelled hickory seeds were treated with moisture absorption and drying twice, ea...

Abstract

The invention provides a method for grafting carya illinoensis, the grafting temperature and humidity as well as stock and scion seedling cultivation before the grafting are strictly controlled, and the method is realized through the following steps of: building a potting cutting orchard, cultivating the stock and automatic temperature control and humidity control grafting; and because the control of the key carya illinoensis grafting links is reinforced, temperature difference between day and night is eliminated, the scion and the stock cut are prevented from expansion with heat and contraction with cold due to the temperature difference, enough water is ensured, the grafting failure due to the water loss of a scion bud is avoided, the grafting survival rate of the carya illinoensis can reach above 85%, and a better horticulture foundation is laid for successfully marketing the carya illinoensis.

Description

technical field [0001] The invention relates to the field of horticultural cultivation, in particular to a method for grafting pecans with thin shells. Background technique [0002] Thin-shell hickory [Carya illinoensis (Wangenh.) k. Koch.], also known as American hickory, is a species of Juglandaceae and Hickory, and is one of the world's famous high-grade nut tree species. Thin-shell pecans are native to North America, mainly in the United States, and have been introduced in my country for nearly a hundred years. Cultivation of fine varieties has extremely high economic benefits. [0003] However, the breeding technology of improved seedlings is one of the main factors hindering the industrialization of hickory nuts. At present, the survival rate of fine seedlings cultivated in China is low and the cost is high. The main method of breeding good varieties of pecans with thin shells is grafting and propagation, but the survival rate of grafting, the utilization rate of ro...
