Problems solved by technology

Studies have also shown that mulching the ground, increasing nitrogen fertilizers, and spraying gibberellin compounds cannot delay the fruit drop of Jincheng (Chun Changpin, 2005)
[0004] Spermidine (Spermidine, Spd) is a polyamine, which was once widely considered as a plant bioregulatory substance. Several studies have shown that Spd plays an important role in plant stress response. However, there is no Any literature disclosing the role of Spd in the preservation of citrus trees

Embodiment 1

[0025] The application process of spermidine in the preservation of citrus trees is as follows:

[0026] The implementation location of this embodiment is Badong County, Hubei Province. The applicant sprayed spermidine on ponkans from 2015 to 2017. There was no rain or snow within 12 hours before and after spraying the reagent, and the spraying continued until the ponkans were sprayed. The spraying concentration of spermidine is 1mmol / L until the water drips on the leaves and fruits.

[0027] Specifically, the spraying time from the end of 2015 to the beginning of 2016 is: December 22, 2015 and January 11, 2016; the spraying time from the end of 2016 to the beginning of 2017 is: December 21, 2016 and 2017 January 10;

[0028] Data statistics and analysis:

[0029] From 2015 to 2017, 3 trees were selected each year as experimental trees, and ponkan plants of the same age and size were selected as controls. The statistical method of the fruit drop rate is to count the fruit d...

Embodiment 2

[0038] The application process of spermidine in the preservation of citrus trees is as follows:

[0039] The implementation location of this example is Wuhan City, where the temperature change is greater than that of Badong, and the winter frost period is longer than that of Badong. Generally, the picking period of ponkan is from late November to late December, which is about half an hour earlier than that of Badong. month picking. Therefore, from 2016 to 2017, the applicant sprayed spermidine for the first time on December 5, 2016, and again on December 30, 2016. There was no rain or snow within 12 hours before and after spraying the reagent. Weather, spray until the water drips on the ponkan leaves and fruit, the spraying concentration of spermidine is 1mmol / L.

[0040] Data statistics and analysis are the same as in Example 1, and the final picking time is February 24, 2017.

[0041] The result is as follows:

[0042] From 2016 to 2017, in the study in Wuhan City, the av...

Abstract

The invention belongs to the field of plant production practice application, and particularly relates to application of spermidine in freshness preservation with branches for citruses. The spermidine is used for treating citruses, thereby obviously reducing overwintering fruit dropping of the citruses, and the fruit dropping rate is obviously different from that of a contrast; furthermore, the quality of fruits is not changed, and the taste cannot be affected. The spermidine (Spd) exists in a human body and a plant body, and can enhance the immunity of a human body and assist a plant in defending adversity stress. The use concentration of the spermidine is 1 mmol / L Spd, which is relatively low; furthermore, after being subjected to spermidine application for month, the citruses are picked; the residual spermidine content in the fruits is extremely low; the spermidine is applicable to large-range popularization.

Description

technical field [0001] The technology belongs to the field of practical application of plant production. It specifically involves the application of spermidine in the preservation of citrus trees. Spermidine can reduce fruit drop during the process of citrus overwintering and keep freshness, ensure the yield and quality, avoid the risk of concentrated fruit listing, and increase the income of fruit farmers. Background technique [0002] Ponkan (Citrus reticulata Blanco) belongs to the citrus species in the broad-skinned citrus category. It is one of the best broad-skinned citrus varieties in the world and one of the best varieties in my country's citrus cultivation. At present, the ponkans cultivated in my country are medium-ripening types, and the fruit harvesting period is concentrated from late November to early January of the following year. With the realization of the economic benefits of ponkan, the national planting area has increased significantly. However, due to ...
