Embodiment 1

[0046] (1) Select the cellar bed: choose a sloping field with a leeward facing sun, good drainage, and a slope of 10 degrees, and the soil quality is clay;

[0047] (2) Preparation of the cellar bed: dig a width of 1.0m and a length of no more than 15m, and then dig side ditches around the cellar pool. Leave ridges with a distance of 10cm. On sunny days, dig 15cm deep cellar bed topsoil in the bed and place them on the surrounding ridges to a height of 10cm. The soil with the side ditch is selected to be stacked in a concentrated place as the heat preservation soil for covering the sweet potato, and the heat preservation soil is aired for one day and then covered with a plastic film for later use, while the cellar bed is dried until the topsoil turns white;

[0048] (3) Cellar storage: pick the selected red sweet potatoes to the side of the cellar bed on a sunny afternoon and gently stack the red sweet potatoes in two layers in the cellar bed. The stacking thickness of red swe...

Embodiment 2

[0053] (1) Select the cellar bed: choose a leeward sunny, well-drained, slope land with a slope of 30 degrees, and the soil quality is brown purple soil;

[0054] (2) Preparation of the cellar bed and disinfectant: digging width 1.33m, length no more than 15m, digging side ditches around the cellar pool, the side ditch is 30cm wide x 30cm deep, the side ditch is connected around and leads out of the cellar bed Drain the water from the outside, and leave a ridge with a distance of 10cm between the side ditch and the cellar bed. On sunny days, dig 15cm deep cellar bed topsoil in the bed and place it on the surrounding ridges to a height of 15cm. The depth of the soil reaches 20cm, and the excess soil and the soil left to dig side ditches are piled up in a centralized place as the heat preservation soil for covering the sweet potato. After drying the heat preservation soil for one day, cover it with a plastic film for later use. White; prepare 70% thiophanate-methyl wettable powd...

Embodiment 3

[0062] (1) Select the cellar bed: choose a sloping land with a leeward facing sun, good drainage, and a slope of 20 degrees, and the soil quality is yellow soil;

[0063] (2) Preparation of the cellar bed: dig a width of 1.2m and a length of no more than 15m, and then dig a side ditch around the cellar pool. The side ditch is 30cm wide and 20cm deep. Discharge, leave a ridge with a distance of 10cm between the side ditch and the cellar bed, dig 15cm deep cellar bed topsoil in the bed on sunny days, put it on the surrounding ridges and stack it 12cm high, the ridges are solid, so that the depth of the final cellar pool reaches 18cm, the excess soil and the soil left to dig side ditches are selected to be piled up in a centralized place as the heat preservation soil for covering the sweet potato, and the heat preservation soil is aired for one day and then covered with a plastic film for later use, and the cellar bed is dried until the topsoil turns white;

Abstract

The invention discloses a fresh-keeping and preserving method of sweet potatoes by using a double-film hot bed, which comprises the following steps of: (1) selecting a cellar bed; (2) preparing the cellar bed; (3) sterilizing the cellar bed; (4) soaking seeds in a medicinal liquid; (5) preserving the seeds in the cellar; (6) earthing up the seeds and covering the earth with films; (7) managing the temperature; and (8) taking the seeds out of the cellar. The method has high sprouting rate and fresh preserving rate, ensures sufficient seeds in production, and preserves nutrients and water; after the seeds are sown, sprouting is fast, and a lot of seedlings emerge, which are beneficial to earlier transplanting for field production; the yield is increased, and the planting area is promoted tobe extended; the production value is increased after preservation, and the newly-added net income of farmers can be doubled; and the invention can provide more raw materials for processing industry, prolong the processing time, promote the development of the processing industry, push forward the deep development of the processing industry, and create more values for the society.

Description

technical field [0001] The invention belongs to a method for storing agricultural products, and in particular relates to a method for overwintering fresh-keeping and storing red sweet potato in a double-film hotbed. Background technique [0002] Sweet potato has a production history of more than 400 years in my country. It has high yield, wide application and strong adaptability. It is an important food crop in my country, and its planting area ranks first in the world. It is one of the main food crops in western China, especially one of the four major food crops in Sichuan and Chongqing. It is a trinity crop of food, feed and economy in Sichuan and Chongqing. It has wide adaptability, strong stress resistance, resistance to barrenness, drought, and alkali. Except for alpine regions, it is planted in hills, mountainous areas, and flat dams. In recent years, with the continuous development of my country's agricultural production, changes in people's food composition, and th...
