Abstract

The invention discloses a method for storing sweet potatoes through the winter. Because requirements for temperature and humidity are strict in the storage process of sweet potatoes, sweet potatoes get mildewed easily due to any carelessness, and economic losses are brought to growers. In the prior art, most sweet potatoes are stored by adopting a cellar lime powder method; however, lime powder emits heat after absorbing water, environment temperature fluctuation is caused easily, sweet potato storage is not facilitated, and sweet potatoes get mildewed and rotted in the storage process. Sweet potatoes stored according to the method are unlikely to get mildewed and are high in freshness.

Description

A kind of Ipomoea batatas storage for the winter method

Technical field

The present invention relates to farm produce storage field, particularly relate to Ipomoea batatas storage for the winter method.

Background technology

Ipomoea batatas is China's staple food crop, and heat content is high, is rich in vitamin, mineral matter, cellulose, present Ipomoea batatas receives wide acceptance as health-care good product, the Ipomoea batatas cultivated area of China was steadily increasing in recent years, and in Ipomoea batatas stable and high yields cultivation, safe storage protects the important step of producing.

Because Ipomoea batatas requires strict in storage to temperature humidity, careless slightlyly easily to go mouldy, cause economic loss to plantation family, the pulverized limestone method storage of existing technology many employings cellar, but heating after pulverized limestone water suction, easily cause environmental temperature fluctuation, be unfavorable for the storage of Ipomoea batatas, cause in storage go mouldy rotten.

Summary of the invention

The object of this invention is to provide and a kind ofly can reduce the Ipomoea batatas storage practice going mouldy rotten in Ipomoea batatas storage for the winter process.

The technical scheme taked in order to the present invention that solves the problem is:

A kind of Ipomoea batatas storage for the winter method, comprises the following steps:

(1) prepare before storage: build storeroom, adopt cellar storage method, with 50% carbendazol wettable powder, 1500 times of liquid, comprehensively sterilized in cellar before storage, get out thick river sand, ash, rice straw, described thick river sand and rice straw are exposed to the sun 7-10 day after utilizing the 1500 times of liquid sterilizations of 50% carbendazol wettable powder under sunlight, get out temperature measuring equipment and hygrometric equipment, remove and need to go mouldy in the Ipomoea batatas of storage rotten individuality, be placed on ventilation airing 5-8 day;

(2) preserve: during storage, thick river sand is laid on bottom cellar, thickness 10-15cm, rice straw is laid on thick river sand, thickness 5-6cm, ash is laid on rice straw, thickness 2-3cm, is placed on Ipomoea batatas on ash, and placement thickness is 40-50cm, rice straw 5-6cm is re-layed thick thick with ash 2-3cm after putting bamboo cane, and then lay Ipomoea batatas 40-50cm, three layers, Ipomoea batatas layer is so laid in each cellar, top layer Ipomoea batatas covers the rice straw of 10-15cm; Temperature measuring equipment is arranged in the Ipomoea batatas heap of intermediate layer, and hygrometric equipment is arranged in cellar open environment;

(3) daily management: under Ipomoea batatas behind cellar for storing things, the storage temperature that controls environment is at 11-15 DEG C, and ambient humidity is at 65%-75%, and when discovery intermediate layer, Ipomoea batatas temperature anomaly rises to more than 15 DEG C, need open cellar ventilating opening, ventilate.

Before Ipomoea batatas is stored sth. in a cellar, use treatment fluid to process, treatment fluid uses the 100 parts of decoctions that add water of monkshood 2 parts, the banksia rose 0.5 part, sealwort 0.6 part, purple perilla 3 parts, the root of straight ladybell 0.2 part, 0.35 part, Poria cocos, curcuma zedoary 4 parts, rhizoma nardostachyos 2 parts to make by weight.

Beneficial effect of the present invention: the present invention utilizes Ipomoea batatas storage experience for many years, abandon traditional moistureproof preservative of lime, adopt the combination collocation of thick river sand, rice straw and ash, coordinate unique storage form, well maintenance group can hide the drying of environment, prevent from Ipomoea batatas from making moist to go mouldy, utilize carbendazim to kill harmful levels of pathogens in cellar simultaneously, to storage accessory also rational sterilization, Ipomoea batatas in preventing bacterial infestation from preserving, provides a good environment for storing, and adopts the present invention to store Ipomoea batatas, mouldly tail off, freshness is high.

Embodiment

The storage for the winter method of Ipomoea batatas, is characterized in that comprising the following steps:

(2) preserve: during storage, thick river sand is laid on bottom cellar, thickness 10-15cm, rice straw is laid on thick river sand, thickness 5-6cm, ash is laid on rice straw, thickness 2-3cm, is placed on Ipomoea batatas on ash, and placement thickness is 40-50cm, rice straw 5-6cm is re-layed thick thick with ash 2-3cm after putting bamboo cane, and then lay Ipomoea batatas 40-50cm, three layers, Ipomoea batatas layer is so laid in each cellar, top layer Ipomoea batatas covers the rice straw of 10-15cm; Temperature measuring equipment is arranged in the Ipomoea batatas heap of intermediate layer, hygrometric equipment is arranged in cellar open environment, use the mode process Ipomoea batatas that rice straw, thick river sand, ash combine, not only high insulating effect, and there is the effect of good dehumidifying, water conservation, relative to other raw materials of use, the successful of storage Ipomoea batatas promotes;

Preferably, before Ipomoea batatas is stored sth. in a cellar, treatment fluid is used to process, treatment fluid uses the 100 parts of decoctions that add water of monkshood 2 parts, the banksia rose 0.5 part, sealwort 0.6 part, purple perilla 3 parts, the root of straight ladybell 0.2 part, 0.35 part, Poria cocos, curcuma zedoary 4 parts, rhizoma nardostachyos 2 parts to make by weight, treatment fluid is spread upon on Ipomoea batatas, store sth. in a cellar after drying, obviously can promote the effect of preservation, prevent crying that Ipomoea batatas in the process of Tibetan is mouldy, blackspot and rotting, relative to not processing, the intact rate of the Ipomoea batatas after process promotes more than 20%.

By finding after practice test, adopt technology of the present invention, when preserving Ipomoea batatas, except only a few Ipomoea batatas goes mouldy, major part Ipomoea batatas is intact, and intact Ipomoea batatas ratio reaches 97.6%, has obvious lifting relative to the intact rate of existing store method 73.6, and the cost that the inventive method is preserved is low, be convenient to promote.

Claims

1. an Ipomoea batatas storage for the winter method, is characterized in that comprising the following steps:

2. a kind of Ipomoea batatas storage for the winter method according to claim 1, it is characterized in that: before Ipomoea batatas is stored sth. in a cellar, use treatment fluid to process, treatment fluid uses the 100 parts of decoctions that add water of monkshood 2 parts, the banksia rose 0.5 part, sealwort 0.6 part, purple perilla 3 parts, the root of straight ladybell 0.2 part, 0.35 part, Poria cocos, curcuma zedoary 4 parts, rhizoma nardostachyos 2 parts to make by weight.
