Embodiment Construction

[0015] A kind of 25-year-old evergreen fruit tree Wenzhou tangerine is a method for changing navel orange Newhall at low temperature and high speed in winter, comprising the following steps:

[0016] 1. Before grafting in winter, cut off the rootstock on the Wenzhou tangerine and cut off all the leaves of the rootstock;

[0017] 2. Select the navel orange Newhall branch scion with 2-4 leaves for outcrop grafting,

[0018] (1) When cutting the scion, select the first full bud at the base, cut off at a position 1.0 cm below the bud, cut off the unfull section, and then bevel at the base of the bud, with the slope forming an angle of 35 degrees, and then, Turn the scion over, with the wide side facing upwards, and make a slash from the base of the bud, so that the cuts on both sides of the scion become wedge-shaped;

[0019] (2), the leafy scion that will be cut is soaked in 100PPM 2.4-D liquid for 1 minute and then used;

[0020] (3) At a smooth place 10 cm away from the broke...

Abstract

The invention discloses a new off-season high-speed top grafting method applicable to evergreen fruit trees such as an elderly orange tree and the like during a low temperature period in winter. The method comprises the following three innovative technologies: 1, cutting off stock, shearing off all stock leaves, and then grafting in winter; 2, carrying out budding grafting by a scion at a branch segment with 2-4 leaves; and 3, reserving all the sprouts on the stock during a spring shoot period after graft survival so that the sprouts grow and develop synchronously with the automatically produced branch tips of the survived scion. By means of the technical effect characteristics in the method which are completely opposite to those of the conventional similar techniques, high grafting survival rate up to over 90% can be easily obtained, a high-yield fruiting period can be quickly entered, and finally the top grafting task is completed.

Description

technical field [0001] The invention relates to a method for high-speed and high-speed grafting and replanting of evergreen fruit trees at low temperature in winter. technical background [0002] At present, in the method of high grafting and replanting of evergreen fruit trees, the following techniques are usually used: generally grafting in autumn, after the grafting survives to the germination stage of the second spring, the second time of film removal and the second time of cutting off the stock to promote budding are carried out, and a single method is used. The scion (or bud sheet) of the bud branch is grafted abdominally, and at the same time, all the buds on the rootstock are wiped out in time at the spring shoot stage, and it is considered that nutrients can be saved for intensive use in the growth and development of the surviving scion. Practice has proved that the consequences of this method are counterproductive. On the one hand, it exacerbated the imbalance betw...
