Description
Technical Field
The invention belongs to the technical field of grafting, and particularly relates to a citrus grafting method.
Background
Currently, the current state of the art commonly used in the industry is such that:
the citrus grafting technique is one of the main methods for production and propagation, that is, the branch or bud of one plant is grafted onto the stem or root of another plant, so that the two parts which are connected together can grow into a complete plant. The grafting method is divided into a branch grafting method and a bud grafting method. The grafted plant (consisting of the overground part scion and the underground part of the stock) can not only keep the excellent characters of the scion variety, but also utilize the excellent characteristics of the stock. The variety of citrus stocks is various, many factors need to be considered in the selection of the stocks, different stocks have certain influence on the root system, crown, tree height, yield, quality, service life, adaptability, stress resistance and the like of citrus, and the good stocks not only can adjust the growth of the trees, but also can enhance the cold resistance, drought resistance, saline-alkali resistance and disease and insect resistance of the trees.
People usually use developed root systems and strong soil fixing property, resistance and growth vigor as the base stocks, but because the developed root systems and strong growth vigor exist, tree crowns are extremely high and large, production management is inconvenient, inter-plant or inter-row sealing is easily caused, the yield and the quality of fruits are influenced, and with the reduction of labor quantity and quality, the base stocks with certain characteristics are often used as intermediate stocks in production, and the influence of the two base stocks on scions is utilized to jointly act on scion varieties so as to achieve the purposes of improving the resistance and the quality of trees, dwarfing the tree crowns and the like. At present, the main intermediate stock source in production mainly adopts high grafting and seed changing, the original eliminated variety is used as the intermediate stock, and the passive high grafting and seed changing tree is easy to grow vigorously, so that the crown is moved outwards, and the operation of agriculture such as pruning, fertilizing, pesticide spraying and the like is inconvenient. The growth speed of plants can be reduced theoretically by grafting another rootstock after the rootstock is grafted, so that the size of the crown can be effectively controlled, but the current seedling raising mode does not exist; in addition, the production high-grafting variety changing is that the intermediate anvil is completely and sequentially connected to the base anvil, and the intermediate anvil is not connected to the base anvil in a reverse mode.
In summary, the problems of the prior art are as follows:
(1) at present, the main sources of the intermediate stocks in production mainly adopt high grafting for seed changing, the original rejected varieties are used as the intermediate stocks, and the seedling raising mode that another stock is grafted after a base stock is used and then scions are grafted does not exist;
(2) at present, the intermediate anvil is completely and sequentially connected on the base anvil in production, and the intermediate anvil is not reversely connected on the base anvil. The existing grafting mode is a conveying mode of conveying water, inorganic salt upwards from the root and conveying organic nutrients downwards, but whether the plant can survive or effectively convey the water, inorganic salt and the organic nutrients after reverse grafting is a technical difficulty, and the growth speed of new scion and new shoot can be reduced by utilizing grafting of the stock after grafting the intermediate stock in the same direction or in the opposite direction, so that the high speed of the tree crown is controlled, the agricultural operations of fertilization, pesticide spraying, pruning and the like are facilitated, and the fruit quality is improved.

The application of the present invention will be further described in detail with reference to the following specific examples;
example 1
1. Materials and methods
The test is carried out in 22 months (sunny days) in 2013 in a Beizhou batch Mazhen white crane orchard, the stock used as the base stock mainly comprises four stock varieties which are commonly used in production, namely Ziyang fragrant orange, tangerine, poncirus trifoliata and poncirus trifoliata, and the varieties used as the intermediate stock are respectively: the branches of the middle anvil are 5cm and 10cm respectively, and the branches of each length are subjected to ventral grafting by adopting sequential grafting (cutting the original base into joints) and reverse grafting (cutting the original top into joints, namely, adjusting the direction of the branches).
The whole nutrient is irrigated before grafting, conventional water and fertilizer and pest and disease damage management is carried out, survival rate is checked after 20 days of grafting, whether the branches are in direct grafting or reverse grafting, the survival rate of 5cm branches is better than that of 10cm branches, all 5cm branches in direct grafting survive (except that 1 orange is grafted on the orange to die), the average survival rate is 83.35%, the survival rate of 10cm branches in direct grafting is very high, only 1 dead branch of the orange grafted on the red orange and the orange is grafted on the orange, and the average survival rate is 91.68%; the survival rate of the reverse grafting branches of 5cm is also higher (only 1 death plant is grafted on the tangerine), the average survival rate is 91.68 percent, the survival rate of the reverse grafting branches of 10cm is obviously reduced, and the average survival rate is only 66.68 percent (see figure 2).
The method comprises the steps of cutting the thin films of two bud holes at the top end of a grafted branch by a knife before sprouting in 26 months 2 in 2014, paying attention to respectively damaging the bud holes, bending a base stock (reversely bending a stock branch above a joint and pressing the stock branch on a nutrition pot) to promote seedling sprouting, and surveying the sprouting number after the first spring shoot aging (5 months and 9 days). The test results are shown in table 1, and the results show that the branches which are directly or reversely grafted on the base stock can normally sprout if the grafting survives.
And (4) conclusion: the normal grafting or the reverse grafting of other rootstock branches on the base stocks can survive, and the survival rates of different rootstocks are different.

2. Results of the experiment
As can be seen from Table 2, the survival rate is high regardless of the forward grafting or the backward grafting, wherein the survival rate of the forward grafting is mostly 60-100%, but the average survival rate is as high as 90%; the survival rate of the reverse grafting is still 60% -100%, but the average survival rate is 75.14%. The survival rate of the scion grafted on the intermediate stock in the direct grafting way is up to 79.26 percent, and the survival rate of the reverse grafting way is 60.12 percent.
3. Results
