Embodiment 1

[0021] The concrete steps of the method for preventing Wendan pomelo fruit cracking disease of the present embodiment are as follows:

[0022] 1. Cultivate rootstock seedlings for the first grafting: select Citrus aurantium as the rootstock for the first grafting, plant Citrus aurantium seedlings in February of that year, wait for the Citrus aurantium seedlings to grow to 0.6m in May, and perform the first grafting;

[0023] S2, the first grafting

[0024] S21, the selection of the rootstock for the first grafting, remove the growth point and the heart leaf of the Fructus aurantii seedlings, cut a 10 mm long crack vertically downward in the middle of the two cotyledons, and make the rootstock for the first grafting;

[0025] S22, the selection of grafted scion for the first time, select Shatian pomelo as the scion of grafting for the first time, cut it into a 10 mm long double-sided wedge with a blade at the young stem both sides at the place 2 cm below the cotyledon of Shatia...

Embodiment 2

[0033] The concrete steps of the method for preventing Wendan pomelo fruit cracking disease of the present embodiment are as follows:

[0034] S1, the rootstock seedling cultivation of grafting for the first time: select Citrus aurantium as the rootstock of grafting for the first time, plant Citrus aurantii seedlings in March of that year, treat that Citrus aurantium seedlings grow to 0.6m in August, carry out grafting for the first time;

[0035] S2, the first grafting

[0036] S21, the selection of the rootstock for the first grafting, remove the growth point and the heart leaf of the Fructus Fructus seedlings, cut a 20 mm long crack vertically downwards in the middle of the two cotyledons, and make the rootstock for the first grafting;

[0037] S22, the selection of grafted scion for the first time, select Shatian pomelo as the scion of grafting for the first time, cut it into a 20 mm long double-sided wedge with a blade at the young stem both sides at 5 cm below the cotyle...

Embodiment 3

[0045] The concrete steps of the method for preventing Wendan pomelo fruit cracking disease of the present embodiment are as follows:

[0046] S1, the stock seedling cultivation of grafting for the first time: select Fructus Aurantii as the stock of grafting for the first time, plant Fructus Fructus seedlings in February of that year, treat Fructus Fructus Fructus seedlings to grow to 0.6m in July, carry out grafting for the first time;

[0047] S2, the first grafting

[0048] S21, the selection of the rootstock for the first grafting, remove the growth point and the heart leaf of the Fructus Fructus seedlings, cut a 15 mm long crack vertically downwards in the middle of the two cotyledons, and make the rootstock for the first grafting;

[0049] S22, the selection of grafted scion for the first time, select Shatian pomelo as the scion of grafting for the first time, cut it into a 15 mm long double-sided wedge with a blade at the young stem both sides at 4 cm below the cotyledo...

Abstract

The invention provides a method for preventing a fruit cracking disease of citrus grandis osbeck. According to the method, a two-pile grafting method is utilized to graft fructus aurantii for the first time to serve as stocks, and Shatian pomelos are used as scions; Shatian pomelo grafting plants are grafted for the second time to serve as stocks, and Shatian pomelos are used as scions, wherein the scions have good affinity with the stocks, and the survival rate is high. Unions are not needed to be processed specially, and the grafting cost is effectively reduced. The method is simple in operation, can be mastered by ordinary skilled persons in the art and is easy to popularize. The method can improve the moisture supply of citrus grandis osbeck fruits at a developing stage and prevent and reduce the fruit cracking rate in a later period of citrus grandis osbeck fruit development and can prevent the fruit cracking disease while ensuring the yield of the citrus grandis osbeck. By the adoption of the method, the fruit cracking rate of citrus grandis osbeck fruits can be effectively reduced on the premise that the yield of the citrus grandis osbeck is ensured, management means including a fertilizer, moisture management and the like are not needed, the production cost is saved, and the survival rate is high.

Description

technical field [0001] The invention relates to the technical field of prevention and control of fruit tree planting diseases, in particular to a method for preventing pomelo fruit cracking disease. Background technique [0002] Pomelo is an excellent fruit tree variety in citrus with large fruit shape, storage resistance, easy management, high and stable yield, and high benefit. However, in the current pomelo production, the phenomenon of fruit cracking of specific varieties of pomelo is serious in some areas, especially the fruit cracking rate of Wendan pomelo is relatively high in the later stage of fruit development. [0003] The main cause of fruit cracking in the later stage is the structural cracking of fruit tissue, that is, the continuous accumulation of soluble solids such as sugars, which increases the osmotic pressure of the juice, increases the ability to absorb water from the outside, and increases the amount of juice. , it is prone to fruit cracking. The usu...
