Embodiment 1

[0014] Changes in the structure of the cork layer of potato microtubers during the treatment of aeroponic potato microtubers before low-temperature storage in the Potato Crop Research Institute of Yunnan Agricultural University, see Figure 1 to Figure 3 shown.

[0015] 1) Processing process:

[0016] a. Sterilization of tubers after harvest: Immediately after potato tubers are harvested, put them in a treatment room with a temperature of 15-18°C and a humidity of 85%-95%, and spread them out in clean containers such as plastic baskets, with a thickness of no more than 3 layers. The next day, the tubers were evenly sprayed with a bactericidal solution containing 5 grams of carbendazim and 5 grams of chlorothalonazim per liter of water, and then the surface of the tubers was air-dried to kill the pathogens on the surface of the tubers.

[0017] b. Tubers turn green: place the sterilized tubers in a green room with a temperature of 15-18°C, a humidity of 85%-95%, and 24-hour li...

Embodiment 2

[0029] Effects of applying the technology of the present invention to the potato virus-free microtubers produced by the Potato Crop Research Institute of Yunnan Agricultural University using the aeroponic method and storing them.

[0030] 1) Sterilization of tubers after harvest: On May 23, 2010, immediately after potato tubers were harvested, they were placed in a treatment room with a temperature of 18-20°C and a humidity of 85%-95%, spread them out in plastic baskets, and placed the tubers for 2 Layer, spray the tubers evenly with a fungicidal solution containing 5 grams of chlorazine and 5 grams of chlorothalonazim per liter of water, and then air dry the surface of the tubers.

[0031] 2) Tubers turn green: Put the sterilized tubers into a green room with a temperature of 18-20°C, a humidity of 85%-95%, and 24-hour light on the second day, and spread them out in a plastic basket with a thickness of 3 layers. Frequently stir until the flesh color of the tubers turns green ...

Abstract

The invention discloses a post-harvest treatment and storage method for a potato minituber produced by a fog culture method, relates to the post-harvest treatment and storage method for the potato minituber and requirements of the potato minituber on an environment during treatment and storage, and mainly solves the problem of difficulty in storage of the potato minituber produced by a fog culture technology or a water culture technology. The post-harvest treatment and storage method comprises the following steps: after harvesting a tuber, timely killing various pathogens on the surface of the tuber, and creating proper environmental conditions for quickly healing wounds on the surface of the tuber, quickly suberifying epidermis, increasing solanine content and laying a foundation for improving resistance to pest and disease damage during storage, keeping freshness and vitality of the minituber and greatly prolonging the storage period; and storing the treated minituber for a long time in a low-temperature high-humidity storage facility. Compared with the conventional storage method, the post-harvest treatment and storage method has the advantages as follows: pest and disease damage is basically not caused during storage, the storage period of the tuber is greatly prolonged to be about 18 months, the water loss of the tuber is very low, and the freshness and the vitality of the minituber are maintained.

Description

technical field [0001] The invention relates to a post-harvest processing method, storage method and environmental requirements of potato miniature tubers, in particular to a post-harvest treatment and storage method for potato miniature tubers produced by aeroponics. Background technique [0002] With the continuous development of the potato industry, the demand for high-quality potato seeds is increasing rapidly. Although the quality of micro-potato potatoes produced by aeroponics is excellent, because the tubers grow in an environment where the nutrient solution is atomized, they have The lenticels are thick and the edges are everted, the weight is small, only 2-5 grams, and the maturity is low and the water content is high. The harvested tubers are prone to dehydration, atrophy, disease, and rot during storage. [0003] At present, there are more and more enterprises and institutions in my country that use nutrient solution hydroponics or atomization cultivation technolo...
