Problems solved by technology

The soil cultivation method generally uses clean soil between the rows on the spot to form a ridge around the trunk and cultivate it. It is not necessary to pat it down. The soil should be as high as possible, but it needs to be checked in time after the strong wind. When there is a gap that cannot be in close contact, it must be filled immediately, but even with such antifreeze measures, frequent personnel care is still required, and the effect is not satisfactory

Embodiment 1

[0026] A method for protecting citrus from freezing damage in winter in the northern edge of citrus plantation, comprising the following steps:

[0027] 1) Preliminary protection: plant windbreaks around the citrus orchard, and cut off late autumn shoots;

[0028] 2) Base fertilizer application: Apply base fertilizer to citrus trees. When applying base fertilizer, dig arc-shaped or ring-shaped deep grooves along the crown of the tree. The depth of the groove is 20-30cm. Apply fertilizer or spread the fertilizer on the ridge surface, and then fully cultivate the ridge surface 20-30cm , when applying basal fertilizer, the young trees should be fully overwintered before mid-to-late October to late November, and the fruit trees should be overwintered before and after fruit picking. Apply winter fertilizer before the end of November, and the winter fertilizer is composed of organic fertilizer and inorganic fertilizer in a mass ratio of 8:1;

[0029] 3) Cleaning up the garden in wi...

Abstract

The invention provides a method for preventing freezing damage of citruses in winter in a northern marginal area of citrus planting, and relates to the technical field of citrus protection. The methodcomprises the steps of primary protection, base fertilizer application, garden cleaning in winter, earthing-up before frost freezing, grass covering, water irrigation before freezing, smoking anti-freezing, accumulated snow removal and the like, wherein during the base fertilizer application, arc-shaped or annular deep ditches are dug along the outside of the crown, and the ditch depth is 20 to 30 cm; fertilizers are applied or the fertilizers are spread and applied to the ridge surface; and then, the ridge surface is fully intertilled for 20 to 30 cm. All steps in the method cooperate with each other to achieve an obvious effect of preventing and controlling the freezing damage of the citruses in winter.

Description

technical field [0001] The invention relates to the technical field of citrus protection, in particular to a method for protecting citrus from freezing damage in winter in the northern edge of citrus planting. Background technique [0002] With the continuous development of social economy, people have very strict requirements for food, clothing, housing and transportation, especially in terms of diet, they all go back to some healthy and nutritious food. The planting area of ​​citrus in our country is very wide, so it has also been received by many People's pursuit, more and more growers joined the ranks of citrus planting. [0003] However, in the process of citrus planting, when the ambient temperature is low or in winter, citrus fruit trees will go dormant or stop growing. Freezing damage occurs when the temperature drops to the point where vegetative organs (leaves, branches, trunks, etc.) or reproductive organs (fruits) are damaged or even die. Therefore, antifreeze w...
