1. Features Energy-saving solar greenhouses Storage Sweet potatoes have the characteristics of large storage capacity, suitable temperature and humidity, easy control, good storage effect, easy access, and low cost. 2. Selection of energy-saving solar greenhouses Energy-saving solar greenhouses run from east to west, facing south, preferably at a width of 7-8 m, depending on the amount of storage, the ridge height is 2.8-3 m, and the back wall height is 1.5-1.8 m. After the roof, in order to improve the insulation effect. The front roof should have a certain degree of solitaryness to prevent accumulation of water. The film should be made of a drip-free longevity film with a thickness of 0.15 mm or more. Insulation material with double grass screen, add a layer of film on the screen to prevent the grass screen water, reduce the insulation effect. The wall thickness of the back wall and east-west gable should reach 0.8m or more. Leave a vent hole with a diameter of 0.6m at the top of the front roof at a distance of 20m to cool and dehumidify. The groundwater level is more than 1.5m, and the soil is tight and deep, so as to prevent water accumulation and easy construction. 3. The construction of a 7m wide energy-saving solar greenhouse can be used for two pits, east-west, with an inverted trapezoidal cross-section, 1.5m wide at the bottom, 2m wide at the mouth, 1.5-2m deep, and 0.8-1m between the two pits. The earthen wall is made up of two sides of the wall by digging the earth. 4, storage (1) shop cellar: the use of the year of the pest-free, non-corrosive corn stalks, after the root shop in the cellar and around, the thickness of 10cm can be. (2) Disinfection: Each 100m2 of sulfur powder 300g + 500g sawdust began to smoke at around 19 o'clock in the evening to disinfect the fumes, it is best to keep the room temperature at about 20 °C, to kill the bacteria on the surface of the greenhouse. (3) Entry into the cellar: Sweet potatoes must be carefully selected before they enter the pit. Remove unqualified sweet potatoes such as disease, insects, rotten, wounds, and freezing, and transport them in baskets to enter the cellar on the day of harvest to prevent overnight frost. Harvesting and loading into the cellar must be avoided to avoid mechanical damage. When entering the cellar, a small bundle of corn stover is placed vertically at intervals of 1.5-2 m for ventilation, and a row of corn stover is placed at a distance of 5 m apart. The sweet potato storage height is 1.5-2m, and the rice leaves covered with 15-20cm thick are kept warm, moisturized and protected from direct sunlight. About 750kg per cubic meter can be stored. 5, management of sweet potato into the pit before the film straw curtain vents should be ready, in the bottom of the cellar, the middle, cellar top and cellar above 1.5m set the temperature and humidity meter, easy to timely and accurate control of temperature and humidity conditions. In the initial period of entering the cellar, care should be taken to adjust the temperature, humidity, and temperature of the greenhouse by adjusting the temperature and humidity in the cellar. The temperature of the greenhouse is adjusted to 10-15°C, and the relative humidity is adjusted to the range of 85%-90%. Inside. In addition, ventilation and ventilation should be conducted in a timely manner to prevent high-temperature, high-humidity, hypoxia, rotting pits and high-temperature germination and health. After entering the pit for 15-20 days, the temperature and humidity changes are basically stable, and the temperature is controlled at 12-14°C. According to the long-term weather forecast, in case of overcast days, the lighting time should be extended and the heat stored to facilitate thermal insulation. Winter should be equipped with heating facilities to prevent special weather. After the end of March, when the temperature rises, it can be used to cover the night and expose the interior, reduce indoor temperature and humidity, reduce germination, and extend storage time.
