Embodiment 1

[0029] The method of the present invention has the effect of preventing sprouting tiller and preventing sunburn of the exposed tree stump after the 6-year-old mokote high is transplanted and replanted with citrus.

[0030] 1. Materials and methods

[0031] The implementation orchard is the Carrizo citrange root Mokot orange tree from the 2nd team of Maliu Village, Xianfeng Town, Jiangjin District, Chongqing City. It was planted in 2011. On February 16, 2016, 10 normal trees with similar size and the same growth were selected. After the main branches, auxiliary main branches and a small number of tertiary branches saw the stumps, the high-grafted trees were replanted with Wokan, and the stumps of 5 high-grafted tree stumps were not subjected to any protection treatment (control), and the other 5 high-grafted tree stumps Adopt the prepared coating of the present invention to evenly paint a layer of coating on all tree stumps (comprising trunk, main branch, auxiliary main branch ...

Embodiment 2

[0041] The method of the present invention has the effect of preventing sprouting tiller and preventing sunburn of the exposed tree stump after the 6-year-old mokot high-grained red meat navel orange is transplanted.

[0042] 1. Materials and methods

[0043]The implementation orchard is the Carrizo citrange root Mokot orange tree from the 2nd team of Maliu Village, Xianfeng Town, Jiangjin District, Chongqing City. It was planted in 2011. On February 16, 2016, 10 normal trees with similar size and the same growth were selected. After the main branch and the auxiliary main branch saw piles, the high-grafting and replanting are red navel oranges, wherein the stumps of 5 high-graining and replanting trees do not carry out any protection treatment (contrast), and the other 5 high-graining and replanting trees adopt the method of the present invention. All tree stumps (comprising the main trunk, the pile heads left after sawing off the main branch and the auxiliary main branch) are...

Embodiment 3

[0052] The method of the present invention has a high effect of preventing sprouting and sunburn of the exposed stump after the 11-year-old tarocco blood orange is grafted with the new species of Longhui red navel orange.

[0053] 1. Materials and methods

[0054] The implementation orchard is an 11-year-old Carrizo citrange rootstock Taroko blood orange tree in Citrus Village, Beibei District, Chongqing. On March 18, 2016, 6 normal growing trees with similar size and growth were selected. After the branch saw pile, the high-grafting and replanting is Longhui red navel orange, wherein the stumps of 3 high-graining and replanting trees do not carry out any protection treatment (contrast), and the other 3 high-graining and replanting trees adopt the prepared coating of the present invention to All stumps (comprising the main trunk, the pile heads left after sawing off the main branch and the auxiliary main branch) are evenly coated with a layer of paint. Do not brush the paint ...

Abstract

The invention relates to a coating for preventing sprouting and sunburn of a stump after top grafting of citrus for varietal change and a use method of the coating. The coating is prepared by mixing and uniformly stirring a polymer cement-based waterproof coating, Portland cement for building, talcum powder for building and sodium naphthalene acetate. The coating brushes the stump to form a yellow gray color; the coating has the advantages of firm bonding of a coating layer, resistance of leaching and flushing from rainwater, breathability, shading, heat insulation and good light reflecting property; after top grafting of the citrus for varietal change, one-time brushing is needed, further the sprouting and the sunburn of the stump can be efficiently prevented, the growth of grafted buds is facilitated, and the recovery of crowns is promoted. A product disclosed by the invention has no adverse influence on citrus trees. A preparation method disclosed by the invention is carried out at normal temperature and normal pressure, safe, energy-saving and environmentally friendly; the use method of the coating has the advantages of simplicity, feasibility, flexibility in use and convenience for popularization and use.

Description

technical field [0001] The invention relates to a coating used for preventing tillering and sunburn of tree stumps after high grafting and replanting of citrus, and provides a preparation method and application method thereof. [0002] technical background [0003] my country is the world's largest producer and consumer of citrus. In 2015, the country's citrus area was 37.7 million mu, with an output of 36.6 million tons. Citrus production has become an important poverty alleviation industry in southern rural mountainous areas. However, due to the rapid development of citrus production in my country and the rapid increase in output, about 80% of citrus are mid-maturity varieties that mature in November-December, and the harvesting period is concentrated, resulting in the increasingly serious problem of seasonal fruit sales. Restrict the improvement of industrial efficiency. In order to solve this problem, in recent years, various citrus producing areas have vigorously promote...
