Potato simple storage method
Pile storage. Per square meter can be scattered heaps of 750 kilograms, surrounded by crates, baskets or wooden panels, about 1.5 meters high, which put a number of bamboo ventilation tube ventilation and heat dissipation. This method is suitable for short-term storage and storage of autumn potatoes at lower temperatures.
Buried. Potatoes are afraid of heat, cold and fear of injury. Potatoes dug up should be kept in a cool place for about 20 days until the skin is dry and then buried. Generally 1.2 meters deep, 1.5 to 2.0 meters deep pit, the length is not limited, the bottom cushion dry sand, the potato cover 5 to 10 cm dry sand. Three layers were buried, the surface covered with straw, and then covered with a thickness of 20 cm of soil. In the ditch, a straw braided air cylinder is placed every 1m or so for ventilation and ventilation. The ventilation cylinder is 40-50cm above the ground. The thickness of the cover soil shall be increased in the winter season, and the ventilation tube shall be closed and blocked with straw mat curtains to prevent rain and snow from entering.
Cellar. Choose a pit where the terrain is high, dry, solid, and sunny. If it is an old cellar, it is necessary to dry the cellar for 7 to 8 days to reduce the temperature in the cellar. Two days before entering the cellar, clean the cellar and scrape off the old walls of the cellar walls and the bottom of the cellar by 3 to 5 cm thick and disinfect. bacteria. In general, each cellar can store 3,000 to 3,500 kilograms, but be careful not to overfill it. It is advisable to store half of the volume of the cellar, up to a maximum of 2/3. The surface of the potato potato piles in the cellar is prone to sweating, and the grasshoppers can be piled on the surface of the potato pile in the cold season.
After the potatoes are stored in the cellar, they are generally not turned over. The cellar temperature during the cellaring period is preferably 3°C. It is easier to germinate than 3°C. When the temperature drops below 0°C, the pit should be covered to prevent frozen potato chips. And to strengthen ventilation management, cellar can not be too humid, relative humidity of about 90% is appropriate, open the spring after the use of night ventilation, daytime cellar method to delay the germination time, the storage process should promptly remove the rot in the pit of potato. This method can be stored until mid-March of the following year.
Naphthalene methyl acetate treatment storage. Thirty-five grams of 98% pure naphthylacetate is dissolved in 30 grams of acetone or alcohol, and then slowly mixed with 1 to 1.25 grams of pre-prepared dry fine mud. Mix well and mix in gauze or coarse cloth as soon as possible. in. Then spread the prepared drug evenly on the 500 kilograms of tuber, pay attention to the drug to be used immediately, and spread the drug evenly. The treated potatoes are piled or boxed and piled on one side and covered in one or two layers of old newspapers or kraft paper on four walls. In general, the greater the dose, the longer the inhibition of germination. The time of drug treatment is generally appropriate after about 2 months after harvest.
