Embodiment 1

[0017] A method for overwintering citrus trees, comprising the following steps:

[0018] (1) One month before overwintering, apply overwintering fertilizer to the citrus trees. The overwintering fertilizer includes the following raw materials in parts by weight: 50 parts of urea, 40 parts of monoammonium phosphate, 30 parts of potassium sulfate, 7 parts of sulfur, 10 parts of borax, and 1 part of zinc sulfate. 1 part, 15 parts of ferrous sulfate, 5 parts of manganese sulfate and 1 part of ammonium molybdate;

[0019] (2) One week before wintering, dig a deep ditch of 80 cm outside the drip line of the canopy of the citrus tree to remove the accumulated water in the field;

[0020] (3) One week before wintering, trim the crown of the citrus tree into a spherical shape, and wrap the crown of the tangerine tree from top to bottom with a transparent plastic film, so that the transparent plastic film is filled with air; the transparent plastic film The part where the lower end is ...

Abstract

The invention discloses a method for overwintering of orah trees, and belongs to the technical field of agriculture. The method includes the following steps that 1, in one month before overwintering,overwintering fertilizer is applied to the orah trees, and the overwintering fertilizer includes, by weight, 50-90 parts of nitrogen fertilizer, 40-80 parts of monoammonium phosphate, 30-70 parts of potassium sulphate, 7-14 parts of sulfur, 10-30 parts of borax, 1-15 parts of zinc sulfate, 15-35 parts of ferrous sulfate, 5-15 parts of manganous sulfate and 1-3 parts of ammonium molybdate; 2, in one week before overwintering, deep trenches of 80-110 cm are dug in the outer sides of water drips of crowns of the orah trees to discharge accumulated water in a field; 3, in one week before overwintering, the crowns of the orah trees are trimmed into spheres and wrapped by transparent films from top to bottom, the interiors of the transparent films are filled with air, the lower ends of the transparent films are tightened and fixed to main branches of the orah trees, and the transparent films cannot move; weeds or films cover lower plates of the orah trees. With the overwintering fertilizer and the transparent films, the orah trees can be protected from cold and kept warm, and can overwinter safely.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for overwintering citrus trees. Background technique [0002] The temperature in winter and spring is low, and the citrus trees are prone to frost damage. In mild cases, the flower buds will be frostbitten, the branches will dry out, and the leaves will fall seriously, which will seriously reduce the yield and quality of the citrus trees. [0003] However, most of the fruit growers who planted the citrus trees basically did not protect the citrus trees when the citrus trees overwintered, so that in the middle of winter, the branches of most of the citrus trees were frostbitten, thereby reducing the yield of the citrus trees and reducing the quality of the citrus trees. Citrus quality etc. Contents of the invention [0004] The purpose of the present invention is to provide a method for overwintering citrus trees, thereby solving the problem of overwin...
