Problems solved by technology

The application of grafting technology in tung tree only stays at the theoretical stage, and there is no precedent for large-scale field experiments. The applicability of different tung tree species is poor, and there are many advantages in disease resistance, lodging resistance and yield improvement of tung tree. There is an urgent need for lack of technology; the proportion of scion terminal buds that can be selected for tung tree grafting is about 5%, and the proportion of axillary buds is as high as 95%. The existing grafting technology cannot meet the needs of large-scale field tung tree grafting

Embodiment 1

[0039] A method for improving the disease resistance, lodging resistance and yield of tung tree, the method is to improve the disease resistance and lodging resistance of tung tree by adopting the grafting technology of tung tree, and also improve the yield of tung tree, wherein the tung tree The grafting technique includes the following steps:

[0040] (1) selection of rootstock and scion: selection age is that No. 27 clonal tung tree of laurel wrinkle of 6 months is rootstock; Selection age is 3 years old high-quality, high-yield, disease-free rice tung tree branch is scion; The branches are annual in the upper part of the tung tree, grow vigorously, have obvious axillary buds, and are lignified or semi-lignified;

[0041] (2) Selection of grafting time: the time selection is from late January to mid-April every spring;

[0042] (3) Grafting by laparotomy; details are as follows:

[0043] A, cutting rootstock: cut obliquely at the wind-in surface of the selected rootstock ...

Embodiment 2

[0052] The invention discloses a method for improving the disease resistance, lodging resistance and yield of tung tree. The method adopts the grafting technology of tung tree to improve the disease resistance and lodging resistance of tung tree while increasing the yield of tung tree. Wherein, described tung tree grafting technique comprises the steps:

[0053] (1) selection of rootstock and scion: selection age is that No. 27 clonal tung tree of laurel wrinkle of 15 months is rootstock; Selection age is 5 years high-quality, high-yield, disease-free rice tung tree branch is scion; The branches are annual in the upper part of the tung tree, grow vigorously, have obvious axillary buds, and are lignified or semi-lignified;

[0054] (2) Selection of grafting time: the time selection is from late August to late October every spring;

[0055] (3) Adopt laparotomy, the specific grafting method is:

[0056] A, cut rootstock: beveled at the quilt surface of selected stock apart fro...

Embodiment 3

[0065] A method for improving the disease resistance, lodging resistance and yield of tung tree, the method is to improve the disease resistance and lodging resistance of tung tree by adopting the grafting technology of tung tree, and also improve the yield of tung tree, wherein the tung tree The grafting technique includes the following steps:

[0066] (1) the selection of rootstock and scion: selection age is that No. 27 clonal tung tree of laurel wrinkle of 8 months is rootstock; Selection age is that the branch on the rice tung tree of 4 years is scion; Described branch is tung tree Annual, vigorous growth, with obvious axillary buds, lignified or semi-lignified branches in the middle and upper part;

[0067] (2) Selection of grafting time: the time selection is from late January to mid-April every spring;

[0068] (3) Grafting is carried out by using the top bud split grafting method, as follows:

[0069] A, cut rootstock: cut off its flat head at the place 30cm away fr...

Abstract

The invention discloses a method for improving disease resistance, lodging resistance and yield of vernicia fordii. According to the method, vernicia fordii is grafted by adopting side grafting, split grafting with top bud and other methods, so that variety improvement of vernicia fordii is quickly realized, and high quality, high yield, disease resistance, lodging resistance and yield increase of vernicia fordii can be realized. By adopting the method, the improved variety has excellent resistance to fusarium oxysporum schl, root rot, giant mealy bug and other diseases; the life of grafted vernicia fordii pure plantation is over 30 years, which is improved by 5-6 times that of conventional pure plantation; the lodging resistance of vernicia fordii is increased by over 30 percent in comparison with that of conventional varieties; and the yield is increased by about 10 percent. The method is applicable to large-scale field cultivation, and construction of about 10,000mu demonstration base is completed by adopting the method.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for improving disease resistance, lodging resistance and yield of tung tree. Background technique [0002] Tung tung is the general name of plants of the genus Vernicia. It is a unique economic forest tree in my country and an important industrial oil tree species. The oil squeezed or extracted from the seeds of tung oil is called tung oil, which is mainly used in manufacturing industries such as lacquer, plastic, electrical appliances, artificial rubber, artificial leather, artificial gasoline, ink, lighting, painting furniture and ships. Aloe tung has a long history of cultivation in my country. As far back as the "Supplements to Materia Medica" written by Chen Zangqi in the Tang Dynasty, there are "poppy tung trees grow in the mountains, trees like phoenix trees" and other historical records about the cultivation and utilization of tung tree. [0003] The t...
