Example Embodiment

[0031] Example 1

[0032] A method for cultivating citrus trees: ①Choose purple soil with loose soil texture and pH value of 5.5-6 to grow citrus trees, and the soil contains about 5% of organic matter; ②Prepare rootstocks and scions, and the scions are 4-year-old For healthy branches on an adult citrus tree, cut off the top of the rootstock, keep the length of the rootstock as 4 cm, cut a 2 cm opening along the epidermis of the rootstock, and insert the prepared scion into the opening of the rootstock, and then use The interface is wrapped with cloth strips; after grafting failure, the grafting method is the same as that for grafting; ③a. When the citrus tree is a sapling, nitrogen fertilizer is applied to the root once in spring, and nitrogen fertilizer is applied 5 times in summer and autumn. Surface spraying, foliar spraying accounts for 2 / 3 of the total fertilization times; when nitrogen fertilizer is applied in autumn, lime is added to nitrogen fertilizer, and the amount...

[0033] Example 2

[0034] A method for cultivating citrus trees: ①Choose sandy soil with loose soil texture and pH value of 5.5-6 to grow citrus trees, and the soil contains about 5% of organic matter; ②Prepare rootstocks and scions, and the scions are 4.5 years old The healthy branches on the mature citrus tree, cut off the top of the rootstock, keep the length of the rootstock as 5 cm, cut a 3 cm opening along the epidermis of the rootstock, and insert the prepared scion into the opening of the rootstock, and then Wrap the interface with cloth strips; make up after grafting failure, in the same way as grafting; ③a. When the citrus tree is a young sapling, nitrogen fertilizer is applied twice to the roots in spring, and four times of nitrogen fertilizer are applied in summer and autumn. The fertilization methods include: Foliar spraying, foliar spraying accounts for 2 / 3 of the total fertilization times; when nitrogen fertilizer is applied in autumn, lime is added to nitrogen ...

Abstract

The invention relates to a method for culturing citrus trees. The method for culturing the citrus trees comprises the following steps that (1) preparing soil, wherein the soil for culturing the citrus trees is purple soil or sandy soil which is loose in soil texture; (2) carrying out grafting; (3) applying fertilizer, wherein (a) when the fertilizer is applied to the citrus trees before maturity, fertilizer application modes comprise root fertilizer application and foliage spray, the mode of the root fertilizer application is adopted in nitrogenous fertilizer application in spring, the modes for fertilizer application in summer and autumn comprise the root fertilizer application and the foliage spray, and lime is added in nitrogenous fertilizer when the nitrogenous fertilizer is applied in autumn; (b), when the fertilizer is applied to mature citrus trees, the fertilizer applied to the mature citrus trees comprises the nitrogenous fertilizer, phosphate fertilizer, boron fertilizer, potash fertilizer and microelements, and the fertilizer application mode is the root fertilizer application; (4) carrying out irrigation, (5) removing dead leaves, frozen branches and certain sick branches and leaves; (6) carrying out winter protection; (7) carrying out pest control. The citrus trees cultured through the method grow vigorously and mature early, the absorption rate and the utilization rate of water and the fertilizer are improved, insect attack cannot occur easily, and obtained oranges are healthier and better in quality.

Description

technical field [0001] The invention relates to a tree cultivation technique in the agricultural field, in particular to a method for cultivating citrus trees. Background technique [0002] Citrus, evergreen small tree or shrub, about 2m high. Branchlets are slender, glabrous, often prickly. Leaves are ovate-lanceolate, 4-8cm long. Flowers yellowish white, solitary or clustered in leaf axils. The fruit is oblate, 5-7cm in diameter, orange-yellow or orange-red, and the peel is thin and easy to peel. It blooms in spring and ripens from October to December. It likes a warm and humid climate, and its cold resistance is slightly stronger than pomelo, lime, and sweet orange. Citrus genus Rutaceae Citrus subfamily is a tropical and subtropical evergreen fruit tree (except Hovenia trifoliata), and there are 3 genera used for economic cultivation: Hovenia citrus, Citrus and Kumquat. The citrus cultivated in my country and other countries in the world is mainly of the genus Citr...
