Method for controlling fruit cracking of jujube trees in fields

A fruit splitting and field technology, applied in the field of jujube tree planting, can solve the problems that restrict the sustainable development of the jujube industry, lose commercial value, and reduce the elasticity of the peel, so as to prevent the premature stop of the growth of the peel cells, reduce the rate of fruit splitting, and reduce the size of the pulp cells.

Problems solved by technology

[0003] Fruit cracking is a common physiological disease of jujube trees. The sugar content of jujubes increases during the ripening period, and the elasticity of the pericarp decreases, turning from tough to brittle; in rainy days, the flesh swells after absorbing too much water, and the pressure increases, causing the epidermis to rupture; Burning and sunburn also cause cracking of jujubes, exposing the pulp, rotten and sour, and thus losing commodity value
The annual loss of jujube production due to fruit cracking is about 35%, more than 80% in severe years, and some production areas even have no harvest, which seriously affects and restricts the sustainable development of the jujube industry

Embodiment 1

[0047] A method for controlling jujube fruit cracking in the field, comprising:

[0048] (1) Cultivation management

[0049] a. Variety selection: choose jujube varieties that are resistant to cracking, high yield and high quality;

[0050] b. Soil selection: choose clay with deep soil layer and good drainage;

[0051] c. Moisture management:

[0052] When the fruit grows to the white ripe stage, water-saving irrigation is used to maintain sufficient water supply in summer high temperature and dry season;

[0053] When the fruit grows to the crisp maturity stage, control the water and cover it with plastic film to reduce water evaporation, keep the soil moisture in a stable state, prevent the growth of peel cells from stopping prematurely, and reduce fruit cracking;

[0054] d. Plastic pruning: adopt a happy tree shape with multiple main branches, leave 3 main branches, and leave 4 small branches on each main branch, then cut off all the remaining dense branches on the main...

Embodiment 2

[0073] A method for controlling jujube fruit cracking in the field, comprising:

[0074] (1) Cultivation management

[0075] a. Variety selection: choose jujube varieties that are resistant to cracking, high yield and high quality;

[0076] b. Soil selection: choose sandy loam with deep soil layer and good drainage;

[0077] c. Moisture management:

[0078] When the fruit grows to the white ripe stage, water-saving irrigation is used to maintain sufficient water supply in summer high temperature and dry season;

[0079] When the fruit grows to the crisp maturity stage, control the water and cover it with plastic film to reduce water evaporation, keep the soil moisture in a stable state, prevent the growth of peel cells from stopping prematurely, and reduce fruit cracking;

[0080] d. Plastic pruning: adopt a happy tree shape with multiple main branches, leave 4 main branches, and leave 6 small branches on each main branch, then cut off all the remaining dense branches on th...

Embodiment 3

[0099] A method for controlling jujube fruit cracking in the field, comprising:

Abstract

The invention discloses a method for controlling fruit cracking of jujube trees in fields, and relates to the field of technologies for planting jujube trees. The method includes (1), carrying out cultivation management; (2), regulating and controlling nutrient elements; (3), regulating and controlling bioactive substances. The method has the advantages that varieties are selected, the field management is carried out, the nutrient elements and the bioactive substances are regulated and controlled, and accordingly the fruit cracking rate of the jujube trees in the fields can be lowered and controlled by the aid of the method.

Description

technical field [0001] The invention relates to the technical field of jujube tree planting, in particular to a method for controlling jujube fruit cracking in the field. Background technique [0002] Jujube is a unique fruit tree in my country, with a cultivation history of more than 3,000 years and rich germplasm resources. Jujube fruit has high economic value and is very popular among domestic and foreign consumers. [0003] Fruit cracking is a common physiological disease of jujube trees. The sugar content of jujubes increases during the ripening period, and the elasticity of the pericarp decreases, turning from tough to brittle; in rainy days, the flesh swells after absorbing too much water, and the pressure increases, causing the epidermis to rupture; Burning and sunburn also cause the jujube to crack, exposing the pulp, rotten and sour, and thus losing its commodity value. The annual loss of jujube production due to fruit cracking is about 35%, more than 80% in seri...
