Embodiment 1

[0027] Embodiment 1, taro variety: taro seed ball of Kui taro class.

[0028] (1) Harvesting: Generally speaking, when the taro leaves turn yellow and gradually shrink, it means that the underground taro tubers are mature. 7 to 10 days before harvesting, watering should be stopped and the field should be kept. When harvesting, clean the stems and leaves first, save some stems, and choose to harvest when the weather is fine. Use a shovel to plan the underground taro along one side of the ridge to avoid damage to the tubers. After digging out, remove the soil, gently break open the taro, and choose a single ball weighing 40-50g as the seed ball, and put it in the The plastic baskets are piled up to 25-30 cm, transported to the indoor pretreatment site, and ventilated and dried for 5 hours.

[0029] (2) Pretreatment: move the taro taro to a nylon packaging bag with a built-in support frame and seal it, and treat it with 1-MCP (1-MCP capsules are placed in a paper bowl or plasti...

Embodiment 2

[0033] Embodiment 2, taro variety: taro seed ball of Kui taro class.

[0034] (1) harvesting method, with embodiment 1.

[0035] (2) Pretreatment: move the taro taro to a nylon packaging bag with a built-in support frame and seal it, and treat it with 1-MCP (1-MCP capsules are placed in a paper bowl with KOH solvent) for 24 hours; each capsule (1-MCP content 1.5mg) to treat 30-60kg of taro taro. Provide the KOH aqueous solution used, the concentration value is 1mol / L.

[0036] The sealed packaging bag is supplemented by pumping to make it in a sub-vacuum state, so as to increase the contact probability between 1-MCP gas molecules and taro, and effectively block the production of ethylene.

[0037] (3) Storage: After the 1-MCP treatment, open the airtight outer packaging bag, take out the paper bowl or plastic cup containing the 1-MCP capsules, use a fan to remove the residual 1-MCP gas molecules in the taro, and move it to a temperature not lower than 4°C. Store in a consta...

Embodiment 3

[0040] Embodiment 3, taro variety: taro seed ball of Kui taro class.

[0041] (1) harvesting method, with embodiment 1.

[0042] (2) Pretreatment: move the taro seeds to a nylon packaging bag with a built-in support frame, seal them, and treat them with 1-MCP (in a plastic cup) for 8; treat each capsule (1-MCP content 1.5mg) with 30-30 mg of taro seeds 60kg.

[0043] Storage: After 1-MCP treatment, open the airtight outer packaging bag, take out the paper bowl or plastic cup containing 1-MCP capsules, and use a fan to remove the residual 1-MCP gas molecules in the taro.

[0044] Pack each bag of 15-30kg and seal it with polyethylene (PE) fresh-keeping bags. During storage, carry out air extraction or nitrogen flushing treatment, and change the air twice every 20 days to reduce the humidity in the bags.

[0045] (4) Inspection: Store in this way until taken out half a month before sowing, check the rot and browning, and check the germination rate.

[0046] Such storage can m...

Abstract

The invention relates to an indoor storage method for Chinese eddo bulbs. The indoor storage method for the Chinese eddo bulbs is characterized in that the method comprises the following steps: 1) harvesting the Chinese eddo bulbs on sunny days and drying the Chinese eddo bulbs for 3-6 hours under a ventilated condition; 2) putting the Chinese eddo bulbs in sealing bags within 30 hours after harvesting, and performing 1-methylcyclopropene treatment for 8-24 hours; 3) after the 1-methylcyclopropene treatment, removing residual free 1-methylcyclopropene by using a fan; 4) moving the Chinese eddo bulbs into a storehouse at temperature which is not lower than 4 DEG C and above a Chinese eddo bulb cold point to perform constant-temperature storage. Compared with the prior art, the indoor storage method for the Chinese eddo bulbs has the advantages that, through air-drying, 1-methylcyclopropene treatment and constant-temperature storage, the rotting and browning rates of the Chinese eddo bulbs can be controlled to be below 10 percent and the strong bud germination rate is above 93 percent.

Description

technical field [0001] The invention relates to an indoor storage method of taro bulbs (belonging to living organisms) Background technique [0002] Fenghua taro is a famous traditional agricultural product in Ningbo, Zhejiang and even the whole country. Ningbo City has a perennial planting area of ​​10,000 mu, an output of 15,000 tons, and an output value of about 100 million yuan. Due to the special geographical environment, climate and soil conditions of Fenghua City, taro head with rich nutrition, good quality and unique flavor has been created, which has always been favored by consumers and has a reputation at home and abroad.
