Embodiment 1

[0031] The application of phytoregulator in the grafting of hickory nut, it comprises the steps:

[0032] Cultivation sites should be selected in areas with deep, fertile soil, good drainage, certain water retention capacity and sufficient sunlight. The grafting time is April 15th.

[0033] The selection of rootstock: choose ground diameter thickness in nursery ground and be 1-2cm, the 1 year old Zhejiang hickory seedling that grows vigorously, without damage by disease and insect is as grafting stock.

[0034] Scion treatment: Before the tree buds have expanded, select healthy branches with a diameter of 0.8-1.6 cm on the thin-shell hickory "Mahan" as the scion.

[0035] Grafting: Cut off the trunk of the rootstock at a distance of 30-50cm from the ground, cut it flat, and then spray the regulator on the cut surface, the spraying amount is 5ml / plant, cut vertically from the middle part downwards, the length of the cut is 2.5cm, and then cut the lower end of the scion by 1 A...

[0041] The application of phytoregulator in the grafting of hickory nut, it comprises the steps:

[0042] Cultivation sites should be selected in areas with deep, fertile soil, good drainage, certain water retention capacity and sufficient sunlight. The grafting time is April 20th.

[0043] The selection of rootstock: choose ground diameter thickness in nursery ground and be 1-2cm, the 1 year old Zhejiang hickory seedling that grows vigorously, without damage by disease and insect is as grafting stock.

[0044] Scion treatment: Before the tree buds have expanded, select healthy branches with a diameter of 0.8-1.6 cm on the thin-shell hickory "Mahan" as the scion.

[0045] Grafting: Cut off the trunk of the rootstock at a distance of 30-50cm from the ground, cut it flat, and then spray the regulator on the cut surface, the spraying amount is 3ml / plant, cut vertically from the middle part downwards, the length of the cut is 2.5cm, and then cut the lower end of the scion by 1 A...

Embodiment 3

[0051] 1, the influence of regulator of the present invention on grafting:

[0052] Group settings:

[0053] Experimental group: Example 1;

[0054] Control group 1: without adding amino acids, the rest are the same as in Example 1;

[0055] Matched group 2: do not add chitosan, all the other are with embodiment 1;

[0056] Control group 3: do not add amino acid and chitosan, all the other are the same as embodiment 1.

[0057] The grafting process of each group is the same as in Example 1, and uniform field management measures such as fertilization, weeding, and intertillage are adopted. On November 20, count the germination and survival of the spikes after grafting, and calculate the grafting germination rate and survival rate, measure the growth of new shoots and the thickness of new shoots on November 20, and measure 300 plants for each treatment to get the average value.

Abstract

The invention belongs to the technical field of forest tree breeding, and discloses a plant regulator for grafting of carya illinoensis. The plant regulator contains the following components: indolebutyric acid, amino acid, gibberellin, chitosan and water. The method disclosed by the invention can rapidly achieve breeding, and is high in survival rate, large in growth increment of tree bodies, andshortened in time for flowering and fruiting. The plant regulator disclosed by the invention is reasonable in formula, has good synergistic performance, and can promote cell division and differentiation, promote callus formation and increase survival rate.

Description

technical field [0001] The invention belongs to the technical field of tree breeding, and in particular relates to a plant regulator for grafting pecans with thin shells and an application thereof. Background technique [0002] Thin-shelled pecans (Carya illinoinensis (Wangenh.) K. Koch) are now known as American pecans. The trunk is straight, the crown is nearly broad and oval, the root system is developed, and it is resistant to water and humidity. It can be planted alone or clustered on lakesides, lawns, etc. It is suitable for garden shade trees and street trees. The urban and rural afforestation tree species and fruit material dual-use tree species can be used to build large economic forests on both sides of the Yangtze River in Jiangsu Province. The kernels are edible, and the delicious oil is squeezed for consumption; the material is tough, and it is an excellent military material. The oil content of the seed kernel is more than 70%. Large tree, up to 50 meters hig...
