Embodiment 1

[0018] Embodiment 1: a kind of method for iron walnut high position square budding, comprises the following steps:

[0019] Step 1. Selection of the grafting period: the grafting time is from June 6th to June 12th, 2011, and the weather is fine;

[0020] Step 2, collection and storage of scions: select semi-lignified shoots of "Qianhe No. 7" with a length of more than 50 cm as scions. Immediately cut off the leaves after harvesting, leave 3cm-4cm long petioles, wrap them in a wet towel, and use them now;

[0021] Step three, grafting: including the following operations:

[0022] (1) Grafting site selection: The transformed iron walnut low-yield tree is 2 years old, and the new shoots with a diameter of more than 1 cm that are fully lignified are selected for grafting. The grafting site is 80 cm above the ground, and each tree is grafted with one bud;

[0023] (2) Grafting: First, cut across the smooth part of the middle part of the grafted new shoot with a double-edged graft...

Embodiment 2

[0025] Embodiment 2: a kind of method for iron walnut high position square budding, comprises the following steps:

[0026] Step 1. Selection of the grafting period: the grafting time is from June 8th to June 13th, 2011, and the weather is fine;

[0027] Step 2, collection and storage of scions: select semi-lignified shoots of "Qianhe No. 6" with a length of more than 50 cm as scions. Immediately cut off the leaves after harvesting, leave 3cm-4cm long petioles, wrap the scion with a wet towel, and use now;

[0028] Step three, grafting: including the following operations:

[0029] (1) Grafting site selection: The transformed iron walnut low-yielding tree is 3 years old. On the three main branches of the central trunk and base of each tree, select fully lignified new shoots with a diameter of more than 1 cm and graft one bud each. The parts are above 80cm above the ground;

[0030] (2) Grafting: First cut across the smooth part of the middle part of the grafted new shoot wit...

Abstract

The invention discloses a method for the high square bud grafting of Juglans sigllata Dode. The method comprises the following steps: selection of the appropriate grafting period, collection and storage of scions as well as the grafting, and management after grafting. According to the invention, a summer high square bud grafting method is adopted to reduce the erosion to a grafting bud caused by the bleeding sap of the Juglans sigllata Dode, so that the high grafting optimization for Juglans sigllata Dode low yielding trees is successfully realized, the grafting survival rate reaches 78 to 92 percent, in addition, wounds can be healed up quickly, the operation is simple, and the grafting efficiency is high and a tree crown can recover quickly, so that the breed improvement problem of Juglans sigllata Dode in Guizhou mountainous area is solved. The method for the high square bud grafting of the Juglans sigllata Dode is simple and low in cost, and has a good using effect and a broad prospect for industrialization application.

Description

technical field [0001] The invention relates to the field of agricultural science, and belongs to a method for asexual propagation and grafting of iron walnuts, in particular to a method suitable for high-position square bud grafting of iron walnuts in mountainous areas of Guizhou. Background technique [0002] Iron Walnut ( Juglans sigillata Dode.) is a unique species of walnut native to the southwestern region of my country. It has the advantages of heat and humidity resistance, strong stress resistance, and good quality. The traditional cultivation of iron walnut in mountainous area of ​​Guizhou mostly adopts seed cultivation, the characters of offspring are separated greatly, many plants have low yield and poor quality of nuts, so it is necessary to use high-quality varieties for high-level grafting transformation. However, iron walnut injury is particularly serious, coupled with problems such as long low temperature in spring in Guizhou mountainous areas, temperature ...
