Problems solved by technology

However, the article does not disclose specific technical content, such as the formula ingredients used, indicators and other data, so there is no actual specific operation guidance
In addition, the technology has not been widely used in the wild, and there is no record of whether it can be applied to rootstocks with a diameter of more than 6 cm that have grown for more than 5 years. The rate is 86.7%, but there is no record of whether the grafted trees can survive the winter safely in the next year, whether they can germinate and grow normally, and how their preservation rate is.

example 1

[0017] On April 6, 2013, along the banks of the Bailong River in Longnan, Gansu, experiments were carried out on a small area: 1,500 seed trees with 5-8 years of plant growth were used for high-graft grafting, and 800 of them used the aforementioned healing-promoting growth of the present invention. agent, and the remaining 700 plants were grafted.

[0018] Specific operation method: the grafting method adopts 1,500 rootstocks to grow 1.2 meters from the ground, strictly according to the grafting technical operating procedures, and implements a healing growth agent with a content of 0.45 mg / kg of naphthaleneacetic acid in 800 strains for the first time. The last 15 days was the first test period, and it was found that callus was initially formed on the edge of the cut where the healing-promoting agent was applied, and the scion buds did not germinate. Callus was produced at the end of the 700 cuts that were not applied. Begin to germinate, and when observing in 30 days, 800 cu...

example 2

[0020] Adopt budding 600 strains, wherein use aforementioned 300 strains of the healing-promoting growth agent of the present invention, do not use 300 strains in the same small class 600 strains, carry out budding test.

[0021] Its specific operation method:

[0022] 600 seedling trees with 5-8 rootstocks were grown from the ground on April 20, 2013 to cut off 1.2 meters, and when the buds were wiped for the first time in 15 days, the new shoots from the top of the trunk in different directions were consciously Leave 3 branches and allow them to fully cultivate and grow, and wipe off the rest. During this period of cultivation and growth, management and protection should be done three times: when the new branch grows to 1 meter, remove the top and trim it in time to promote the semi-lignification of the new branch. Budding was carried out on June 10.

example 3

[0024] From April 5th, 2014, in 10 key villages and towns in the Longnan area of ​​Gansu Province, the healing growth agent of the present invention was used for grafted walnuts to carry out large-scale field promotion and application in different growth environments, conditions, climates and different soil properties. , complete the grafting of 520,000 strains in total, wherein; 470,000 strains are suitable for branch grafting, and 50,000 strains are suitable for bud grafting. According to factors such as different environments, the content of naphthaleneacetic acid was regulated within an appropriate range.

[0025] See the table below for all the other examples:

[0026]

[0027] After cross-checking and acceptance by the government and the grassroots, the average survival rate of each implementation area is 89.4%, creating the best level of survival rate for walnut branch grafting and budding in the history of this area. Experiment also shows that no matter the scion a...

Abstract

A grafting healing-promoting growth stimulator for walnut trees and a preparing method thereof are disclosed. The preparing method includes: cleaning rhizoma cimicifugae, adding clear water with 50 kg of the clear water being added into 10 kg of the rhizoma cimicifugae, decocting for 60 min, filtering to remove dregs, cooling filtrate to obtain a rhizoma cimicifugae water extract liquid, adding 6 parts by volume of water into 1 part by volume of the rhizoma cimicifugae water extract liquid to obtain rhizoma cimicifugae juice, and adding 0.30-0.50 mg of 1-naphthylacetic acid into each kg of the rhizoma cimicifugae juice to obtain the grafting healing-promoting growth stimulator. Related experiments show that: the grafting healing-promoting growth stimulator can increase the rate of survival of grafting, a grafted fruit tree grows vigorously, a semi-lignified degree can be achieved, the tree can be ensured to go through the winter safely, and normal growth in a next year is benefited.

Description

technical field [0001] The invention relates to a medicine for promoting the healing and growth of grafted parts when woody plants are grafted and a preparation method thereof, in particular to an agent for promoting healing and growth of walnut tree grafting and a preparation method thereof. Background technique [0002] In the grafting of forest trees and fruit trees, the grafting of walnut trees is difficult. Due to many internal and external factors of the walnut plant, especially the influence of the endogenous substances of the walnut plant, such as the increase in the content of coumaric acid, it is not conducive to the survival of grafting. In addition, it is also affected by many other factors, such as: geographical location, growth environment, climate change, soil properties, shady or sunny side of the plant, and altitude. For solving and properly handling these contradictions, in the technical field of walnut tree grafting, many methods and measures have been ado...
