Embodiment 1

[0019] A pre-harvest and post-harvest composite treatment method for AP custard fruit preservation and inhibition of dehiscence, comprising the steps of:

[0020] (1) Preparation of preharvest compound solution: compound calcium chloride and jasmonic acid, the mass volume percentage concentration of calcium chloride after preparation is 3%, and the mass concentration of jasmonic acid is 1mmol / L;

[0021] (2) Selection of experimental fruit trees: 8 AP custard apple trees with basically the same size, height, growth, number of fruits, and maturity of fruits were selected in the same orientation and similar area of ​​the orchard;

[0022] (3) Pre-harvest treatment: Between 4:00 p.m. and 6:00 p.m. two weeks and one week before picking the fruit, spray the pre-harvest compound agent solution on the fruits of 8 AP custard apple trees until the fruit is wet;

[0023] (4) Timely harvesting of fruits: select AP custard apple fruits with uniform size, no pests and diseases, no damage, ...

Abstract

The invention relates to a preharvest and postharvest compound treatment method for AP annona squamosa refreshment and fruit cracking restraint. The preharvest and postharvest compound treatment method comprises the steps of enabling complexing agent solution composed of water, calcium chloride and jasmonic acid to be spayed on fruits 1-2 weeks before picking; selecting and harvesting the fruits which are uniform in sizes, have no pest and disease damage and have a maturity of 80-90%; first soaking the harvested fruits in pollution-free preservative solution I composed of water, citric acid, oxalic acid and ascorbic acid for 20-30min, taking out the fruits, and draining moisture; soaking the fruits in preservative solution II onion extracting solution; finally enabling the processed fruits to be aired naturally in an air-conditioning room at 18-20 DEG C, and storing the fruits in a cold storage which is at 15 DEG C and has a relative humidity of 75%-85%; and after storage for 15 days, enabling the fruit cracking rate and the rotting rate of AP annona squamosa to be reduced to be within 15%. According to the preharvest and postharvest compound treatment method, the fruit cracking rate can be effectively reduced, the storage period of the fruits is prolonged, and the flavor and quality of the AP annona squamosa are not affected.

Description

technical field [0001] The invention relates to a method for keeping tropical fruits fresh and suppressing fruit cracking, in particular to a method for pre-harvest and post-harvest composite processing of AP custard apples for keeping fresh and inhibiting fruit cracking, and belongs to the technical field of fruit fresh-keeping. Background technique [0002] cherimoya ( Annona squamosa L.) Also known as Ringo, Sakyamuni, commonly known as sweet lychee, sweet fruit, belongs to the Annonaceae ( Annonaceae ) is a deciduous small tree, which is a rare fruit in tropical and subtropical regions. It is planted in several provinces in southern my country, especially in Guangdong, Hainan, Fujian and other provinces. The custard apple has a unique flavor, is sweet and refreshing, rich in nutrition, rich in VC, and low in fat. The majority of consumers of all ages. AP custard apple, formerly known as African Pride, is a hybrid of common custard apple and Peruvian custard apple, ...
