Embodiment 1

[0026] The application of 1-methylcyclopropene in reducing citrus overwintering fruit drop and / or prolonging citrus harvest period is as follows:

[0027] The implementation location of this embodiment is Badong County, Hubei Province. The applicant carried out the spraying treatment of 1-methylcyclopropene on ponkans from 2015 to 2017. There was no rain or snow within 12 hours before and after spraying the reagent. Apply until the water drips on the leaves and fruits of the ponkan, and the spraying concentration of 1-methylcyclopropene is 1mg / L.

[0028] 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;

[0029] Data statistics and analysis:

[0030] 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 s...

Embodiment 2

[0039] The application of 1-methylcyclopropene in reducing citrus overwintering fruit drop and / or prolonging citrus harvest period is as follows:

[0040]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, the applicant sprayed 1-methylcyclopropene for the first time on December 5, 2016 from 2016 to 2017, and sprayed it again on December 30, 2016, within 12 hours before and after spraying the reagent. In the absence of rain and snow, spray until the leaves and fruits of the ponkan leaves and fruits are dripping, and the spraying concentration of 1-methylcyclopropene is 1mg / L.

[0041] Data statistics and analysis are the same as in Example 1, and the final picking time is February 24, 2017. ...

Abstract

The invention belongs to the field of plant production practice and application, and particularly relates to application of 1-methylcyclopropene in reduction of orange overwintering fruit abscission and prolonging of the picking period. Oranges are processed through 1-methylcyclopropene, orange overwintering fruit abscission can be remarkably reduced, and the fruit abscission rate is remarkably different from that of the contrast; the orange picking period is prolonged, meanwhile, it is ensured that the fruit quality does not change, and taste is not influenced. The use concentration of 1-methylcyclopropene (1-MCP) is 1 mg / L, and 1-methylcyclopropene is low in concentration and easily volatize. Picking is conducted one month after spraying treatment, no toxin, harm or residues exist, the environment is not polluted, and 1-methylcyclopropene is suitable for large-scale popularization.

Description

technical field [0001] The technology belongs to the field of practical application of plant production. It specifically relates to the application of 1-methylcyclopropene in reducing fruit drop during the wintering process of citrus trees, and ensuring the yield and quality of citrus when prolonging the harvest period. Extend the harvest period of citrus, effectively avoid the risk of concentrated fruit listing, and increase the income of fruit farmers. Background technique [0002] Ponkan (Citrus reticulata Blanco) belongs to the broad-skinned citrus category, and is one of the best varieties of wide-skinned citrus in the world, and also one of the best varieties in my country's citrus cultivation. At present, the ponkans cultivated in my country are mainly middle-maturing 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...
