Method for determining number of yellow shoot disease trees in navel orange orchard

Abstract

The invention discloses a method for determining the number of yellow shoot disease trees in a navel orange orchard. The method is characterized by comprising the following steps: standardized planting of the earlier stage is performed, to be specific, navel orange seedlings are planted at intervals of three meters in a matrix; diseased seedlings are identified; the identification means includes planting region identification and non-planting region identification; planting region identification is performed according to three growing periods, and the three growing periods include a fruit treegrowing period, a fruit tree shoot growing period and a fruit ripening growing period; and non-planting region identification includes seedling call-out field identification and pest infection identification. The diseased trees in the orchard are determined by the method for determining the number of the yellow shoot disease trees in the navel orange orchard, and thus, the number of the diseasedtrees can be rapidly determined in time, and then, a corresponding response measures can be rapidly taken, so that huge losses caused by the yellow shoot disease are effectively reduced.

Description

technical field [0001] The invention relates to the technical field related to navel orange planting, in particular to a method for measuring the number of greening disease trees in a navel orange orchard. Background technique [0002] Navel orange, formerly known as: sweet orange. Alias: orange, navel orange, sweet orange, orange, Gemini, Sapindus, Rutaceae evergreen small tree, branchlets glabrous, branch thorns short or absent. The leaves are oval or ovoid, with entire edges or no blunt teeth; the petiole has narrow wings and joints at the top. Navel orange is an excellent citrus variety cultivated by all countries in the world. At present, many high-quality navel oranges are also cultivated in various parts of my country. Navel orange is rich in nutrition. Contains all kinds of nutrients necessary for the human body. Navel orange contains a lot of vitamin C and carotene, which can help inhibit the formation of carcinogens, soften and protect blood vessels, promote blood ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for measuring the number of trees with Huanglongbing disease in navel orange orchards, so as to solve the problem mentioned in the above-mentioned background technology that when planting, the most feared thing is that the seedlings are infected with Huanglongbing disease. Once infected with Huanglongbing disease, it will seriously affect Harvest, and Huanglongbing spreads extremely fast, but there is no rapid method of detecting Huanglongbing diseased trees, so that it is impossible to identify and control Huanglongbing as early as possible
