Abstract
The invention discloses a method of retaining the freshness of sweet potatoes by geothermal water. In the severe winter, the outside temperature is low; the temperature in a freshness retaining warehouse is reduced with the outside temperature; when the temperature in the freshness retaining warehouse is reduced to be lower than 9 DEG C, a temperature sensor of the freshness retaining warehouse is switched on by a temperature controller, and an automatic water supply switch supplies water; geothermal water with the temperature of 48 DEG C is conducted and dispersed into the sweet potato freshness retaining warehouse through a 2-inch hot-galvanized pipeline; when the temperature in the warehouse returns back to 14 DEG C, the temperature controller informs the water supply switch to stop supplying water so as to effectively control the sweet potato freshness retaining temperature within 9-14 DEG C all the time; therefore the problem of kiln burning caused by a large amount of breathing heat release after sweet potatoes are harvested and the problem that the sweet potatoes are infected with soft rot diseases and rotten in the kiln due to low temperature in the severe winter are solved. As the practical geothermal water is fed through the pipeline for sweet potato freshness retaining, the influence caused by winter low temperature in the sweet potato freshness retaining warehouse on large-scale sweet potato freshness retaining is avoided, and the aim of large-scale sweet potato freshness retaining is fulfilled.
Description
Technical field
The present invention relates to agricultural technology field, be specifically related to a kind of GEOTHERMAL WATER that utilizes and fresh-keeping method is carried out to sweet potato.
Background technology
Sweet potato is a kind of nutritious, integration of drinking and medicinal herbs, broad-spectrum main farm produce, and because its moisture is large, sugar content is high, and content of starch is high, perishable, rotten.Therefore fresh-keeping the obtaining all the time of sweet potato properly effectively solves, and in particularly winter, sweet potato is afraid of to freeze, and the storage of surviving the winter of sweet potato is then an insoluble problem, directly affects my enforcement of liang potato Development Strategy and the development of rural economy.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method to be easy to realize, and what feasibility was good utilizes GEOTHERMAL WATER to carry out fresh-keeping method to sweet potato.
Technical problem to be solved by this invention realizes by the following technical solutions:
Utilize GEOTHERMAL WATER to carry out a fresh-keeping method to sweet potato, concrete steps are as follows:
1) fresh-keeping warehouse construction:
Storehouse body construction adopts brick concrete structure, and build long 26 meters, wide 15 meters, the fresh-keeping warehouse body of wall of high 4 meters, storage capacity accounts for 70% of gross space; Body of wall installs insulation material, and storehouse internal head cover adds Anti-fogging Film prevention " sweat gas ", water droplet;
2) after storehouse body builds up, auxiliary construction automatic temperature controlling, the wet device of control:
By body of wall one week 20 centimetres high, arrange 2 cun of galvanizing pipelines, pipe end is opened silk and is connected GEOTHERMAL WATER well water pump outlet pipe, and underground heat well is 1200 meters of dark underground heat wells, water temperature 48 DEG C; Pipe ends joint fluid sealant or band seal, and prevent galvanizing pipe leakage, flow in fresh-keeping warehouse; Pipeline passes into sweet potato fresh-keeping warehouse corner place and installs automatic control switch; Settle counterpart window before and after storehouse, the double-deck white glass of sash, glass ectonexine interval 3-4 centimetre, centre is thermal insulation layer, is beneficial to storehouse inner heat insulation; Sash is dull and stereotyped self-pulling type, reinforces and is sealed on body of wall, control storehouse temperature with 5-7 cm thick polyurethane thermal insulation board;
Fresh-keeping warehouse very useful polyethylene dripless water plastic sheeting for farm use, adopts chevron shaped or slope to become 70 degree of pull-ups with body of wall; Slightly high in the middle of ground level in storehouse, Ti Kaoqiang limit, storehouse is dug wide 20 centimetres, the ditch of dark 8-10 centimetre, for accepting the waste water flow down without the plastic sheeting for farm use that drips, in case the contaminated wastewater potato block that sweet potato is discharged;
Facility in storehouse is installed, observes indoor location automation controller outside storehouse, all automation installations in this controller link library, as sash, ventilation fan, GEOTHERMAL WATER pipe gauge tap, humidification water pump, temp probe and humidity probe etc.; Fresh-keeping warehouse ground does not need sclerosis, is conducive to the conduction circulation of water and ground temperature on the ground;
3) process before sweet potato warehouse-in:
Put first 3 days in storage, with 80% carbendazim, 600 ~ 800 times of liquid comprehensive sterilizations, in case by bacterial invasion after sweet potato warehouse-in;
4) manage: overwintering period, when storehouse temperature is lower than 9 DEG C, automation controller can automatic power transmission to GEOTHERMAL WATER pipe gauge tap, pipeline water flowing, storehouse temperature controls between 9-14 DEG C always, and enter at the beginning of in by the end of March, the 2nd to 5 month, daytime temperature is high, nocturnal temperature is low, when night, ambient temperature was lower than 15 DEG C, air interchanger is opened automatically, discharges carbon dioxide warm in storehouse, suck extraneous fresh cold air simultaneously, make storehouse temperature be reduced to less than 15 DEG C;
When relative moisture in storehouse lower than 80% time, automatic controller to humidification water pump, carries out ground moisturizing with regard to power transmission, increases air humidity, and make sweet potato keep a moistening storage environment, this is conducive to potato block and keeps certain moisture and tender and crisp mouthfeel.
The invention has the beneficial effects as follows: the sweet potato automatic temperature controlling control scale that wets preserves energy-saving fresh-keeping storehouse and semi-underground certificate formula fresh-keeping warehouse, and underground storage storehouse is compared, and has obvious preservation and freshness advantage:
1) storage fresh-keeping capacity is large, and novel warehouse storage capacity is comparatively large, general 1 warehouse 400m
2can deposit sweet potato 300,000 kilograms, be about 10 times of common storage storehouse, therefore, it is more suitable for scale storage fresh-keeping, has prior meaning to the sweet potato deep processing enterprise produced throughout the year.
2) epidemic disaster is controlled, novel warehouse can control effectively to storehouse temperature and humidity, according to the epidemic disaster requirement that sweet potato is deposited, can manually arrange, storehouse temperature controls within the scope of 9 ~ 14 DEG C, and realize automatically controlling, to meet the requirement of sweet potato in the winter time to temperature in storage process, guarantee sweet potato not by freeze injury; Meanwhile, by specifically equipping facility, make in storehouse keep 85% ~ 95% relative moisture, guarantee the moisture of sweet potato and mouthfeel unaffected, play good fresh-keeping effect.
3) prolong storage period, result of the test shows, the storage fresh-keeping phase of novel warehouse is 180 days, and the freshness date at common cellar for storing things is 120 ~ 130 days, novel warehouse extends 50 ~ 60 days compared with the freshness date in normal storage storehouse, thus playing the effect effectively regulating market supply, anti-season is gone on the market, and also makes sweet potato be worth simultaneously and gets a promotion.Therefore usual in May, the 2nd sweet potato price be 3 ~ 4 times of harvest season.
Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific embodiment, setting forth the present invention further.
