Abstract

The invention relates to a simple indoor preserving method for sweet potatoes. The simple indoor preserving method includes the steps that before frosting occurs, the ripe sweet potatoes are harvested on a sunny day, potato stalks and vines 5 cm to 15 cm in length are reserved during harvesting, careful digging, careful taking and careful transport are conducted, and digging injuries, touch injuries and breaking should be prevented to the greatest extent; the sweet potatoes are aired to enable skin to be dry, the sweet potatoes without diseases, insect holes and the digging injuries and with the single weight larger than 60 g are selected to be directly placed into bags, the weight of the sweet potatoes in each bag ranges from 20 kg to 25 kg, and bag openings are well tied; after the sweet potatoes are dug up and transported to the home, the woven bags with the sweet potatoes are directly stacked in a storage room in the length direction of the bags layer by layer till five to six bags are stacked in the height direction, parallel lines are formed, and spacing reserved at the two ends of each line ranges from 30 cm to 50 cm so that convenience can be brought to ventilation and management.

Description

The simple and easy preserving process of a kind of indoor Ipomoea batatas

Technical field

The invention belongs to grain preservation technology field, particularly relate to the simple and easy preserving process of a kind of indoor Ipomoea batatas.

Background technology

According to data report, in Ipomoea batatas, be rich in bata-carotene, zinc, iron and pyridoxamine, the heat that every 100 grams of Ipomoea batatas produce is lower by 1/3rd than rice, and the content of vitamin B1, vitamin B2 exceeds 3-6 doubly than rice.In Ipomoea batatas, contain abundant lysine, satiety can increase sharply.And contained potassium in Ipomoea batatas can effectively be prevented and treated the generation of the angiocardiopathy such as hypertension and prevention of stroke.The World Health Organization has issued " 2007 Global Health food ranking list ".Because sweet potato dietary fiber content, content of chemical substances are few, " vegetables list " umber one is stepped in honor for the first time.In addition, sweet potato leaves, nutritional labeling is also very abundant, and Vegetable Research center, Asia is referred to as " vegetables queen ".In every 100 grams of fresh sweet potatoes leaves, contain 2.28 grams, protein, 0.2 gram, fat, 4.1 grams of sugar, 16 milligrams, potassium, 2.3 milligrams of iron, 34 milligrams, phosphorus, 6.42 milligrams of carrotene, 0.32 milligram of vitamin C.Studies show that the food that edible sweet potato leaves is made has digestion, stomach invigorating, defaecation, raising immunologic function, hemostasis, hypoglycemic, the vision protection of promotion, delays senility and the effect such as skin care.Most importantly: Ipomoea batatas is preferably in this prime time of lunch and eats, because eat up after Ipomoea batatas, calcareous in potato need to be through within 4-5 hour, absorbing in human body, and afternoon, solar light irradiation can promote the absorption of calcium.Sweet potatoes is the thing that people take a lot of trouble always, slightly inconsiderately will make intact Ipomoea batatas rot.Therefore, people have thought a lot of ways, and as cellar for storing things storage, grain bin, chamber, antistaling agent etc., effect is undesirable, program complexity.

Summary of the invention

For overcoming above-mentioned weak point, invent this method: select breedingas osmanthus through No. 2, potato, osmanthus through No. 3, potato, osmanthus through No. 5, potato, osmanthus through No. 6, potato etc.; seize the opportunityipomoea batatas autumn planting, implantation time is than common 5-10 days in advance, and results are before frost occurs, because frost meeting frostbite Ipomoea batatas, the Ipomoea batatas of frostbite is difficult for storage for a long time, selects bright day gas the morning ripe Ipomoea batatas to be gathered in the crops; prepare Ipomoea batatas storeroomselection has window, the airtight Zuo Zhu chamber, room of energy that physical features is slightly high, and clean, sterilize for 5-15 days in advance; the preparation of storage bag and ropeselection filled the rotten old sack of not having of cement or did not go up the woven bag of slurry, in order to ventilation, cleaned, and dried, simultaneously prepare the rope of bundle sack, as the rope made of hemp, cotton thread; when results, stay 5-15CM long potato handle and rattan, note gently digging, gently take, gently transport, prevent from digging wound, damage and fractureing as far as possible, dry epidermis.Select good potato pack: do not have disease insect population and the single heavy 60 grams of above Ipomoea batatas that dig wound directly to put into bag, every packed Ipomoea batatas 15-25 kilogram, has tied sack; ipomoea batatas seasoning, after Ipomoea batatas digs back, by the woven bag direct code that Ipomoea batatas is housed be placed on storage chamber in, straight keeps flat, and then it is high to stack from level to level 5-6 bag in the above, form line by line parallel, the two ends of every row and spacing 30-50 centimetre, so as to ventilate and management. the management of storage chamber(1) temperature treatment Ipomoea batatas starts rudiment more than 15 DEG C, easily infects sick under hot conditions; Be subject to below freeze injury at 10 DEG C, be subject to freeze injury Ipomoea batatas to subject to Bacteria erwinia and infect rotten.Therefore, the preference temperature of Ipomoea batatas storage is 10 DEG C～15 DEG C.Usable temp instrumentation amount room temperature and potato stack temperature, according to temperature conditions, increase and decrease covering, or the amount of door window also can regulate the room temperature with the measure of seal up a door window insulation or door window heat release.(2) behind moisture management potato piece people chamber, when indoor humidity is lower than 80% time, the moisture in potato piece is evaporation outward just, causes the dehydration of potato piece, wilting, shrinkage, the chaff heart, and edible quality declines.When relative humidity exceedes 95%, the potato piece brown stain of fading, pathogen breeding, rotting rate rises.Require indoor relative humidity to be stabilized in 80%～90%.Note timely adjusting, should be to the potato piece clean cold water of splashing when humidity is too small, the venting of should ventilating when humidity is excessive, reduces humidity.Checked temperature, humidity and potato heap state every 10 days one time, while finding that there is rotten potato, sort out in time.(3) light management does not allow direct sunlight store chamber.Points for attention (one) alcohol prohibition, oils.The personnel of drinking can not enter the room, and accelerate to rot because cocktail party makes potato piece; Oil is also like this.(2) other fruits of firework control and foreign material, in case pathogen contamination.Like this storage Ipomoea batatas, both met required temperature, humidity, light and the api request of Ipomoea batatas physiology, again unlikely make to breathe too fast, grow accelerate, advance germination.The invention has the beneficial effects as follows: in order to the pachyrhizus of upper method storage, fresh keeping time can reach 5 months, and pachyrhizus serviceability rate can reach 93%.By fresh-keeping, can extend the supply time of Ipomoea batatas.Method is simple, safe, economic, practical, is applicable to rural area and promotes.

Detailed description of the invention

Below in conjunction with embodiment, the present invention is further illustrated.19.1 DEG C of county's average year temperature on average, 38.5 DEG C of Extreme Maximum Temperatures, the extreme lowest temperature-4.0 DEG C; Mean annual precipitation is 1 566.1 mm, and in 1 year, precipitation is the variation of " many in the middle of two is few ", and precipitation concentrates on for 4-September relatively, and rainfall reaches 1213.9 mm, accounts for 77.5% of annual rainfall.On average in mid-November, frost occurs, and generally all in the early November Ipomoea batatas of gathering, this method can preservation can not be germinateed or rotten to the April of next year.The Guangxi Luo Chengxian east gate town Huang of Baima community, excavates 5865 kilograms, Ipomoea batatas by upper method on October 29th, 2012, and preservation is to next year daily inspection in April 2, and storage time reaches 5 wheat harvesting periods, Ipomoea batatas serviceability rate 95%.
