Spring potato sprouts preservation
In recent years, in southern central Yunnan, potato and cotton have larger units and planting areas. Potatoes are planted in the spring and harvested in the middle and late June. Intercropping areas produce more than 10,000 kilograms of potatoes, and are stored until the vegetable market is sold in the off-season in August. The price is good and efficient. After the spring potato is harvested, it is stored under high-temperature and high-humidity conditions from June to July, and budding will occur after more than one month of dormancy. After the potato germinates, the nutrients in the body are consumed quickly, the cortex appears shrinking, the tubers start to reduce, the germinating part is poisonous, the food is not safe, and the taste is not good, which affects the market sales and directly influences the popularization of the new planting technology between potato and cotton. In order to solve the problem of sprouting during storage of spring potatoes after harvest, we introduced potato sprouts (CIPC) from DECCO, USA, and used sprout inhibitors during the storage and preservation of spring potatoes. The research work has formed a complete set of storage bud suppression techniques, ranging from species selection and harvesting requirements, from selection of storage sites to the use of inhibitors for the use of inhibitors, and has achieved significant results. 1. Variety selection and harvesting In the spring of planting potatoes in the south of Fujian, it is necessary to select early-maturing cultivars such as Zhengshu 5 and Jintai 8 and the growth period is 80 to 90 days. In mid-March, the mulching film covers the planting and can be harvested before and after the summer solstice. Long-growing varieties do not mature normally before they enter the hot season, and they begin to bud in the soil, affecting safe storage after harvest. Potatoes should be harvested before 11am and after 3pm. When the spring potato is harvested, the outer coriaceous material is still poor. When it is shipped, it is easy to damage the epidermis. After entering the pit, it causes rot. It should be lightly loaded, lightly transported, and gently unloaded to avoid wounded epidermis and shattered fries. 2. The choice of place and storage of the potatoes have a great influence on the market supply and quality. After harvesting, the potatoes should be stored in a clean, ventilated, cool, dry semi-basin or indoors. The tubers should be stacked on clean sand and the thickness should not exceed 33 cm. After the potato block is put into the pit, it is poured 3 to 5 days, and it is poured into the pits and chambers within 15 days. It is found that the rotten potato blocks are picked up at any time to prevent the spread of other potato chips. To keep the cellar, indoor drying, ventilation, and require dark storage, to prevent the potato block after the light turn green, solanine increase, loss of food value. Can be covered with newspapers and haystacks on the potato piles, or weeds or dark curtains can be added to the windows. During the day, the window can be closed halfway, and ventilation and cooling can be performed at night to extend the safe storage period of the potatoes. Continue to store in the winter, through the regulation and control measures, keep the pit, the indoor temperature reaches 4 °C ~ 6 °C above, from frost damage. 3. Medicament selection and use During the storage period of spring potatoes, the dormancy period of potatoes is shortened due to the influence of high temperature and high humidity environment. After one month of storage, the germination begins. The measures to control potato sprouting include temperature control and chemical treatment. We chose Daike's bud inhibition agent (potato bud inhibition agent, which was registered in China in 1993 and obtained approval from the Ministry of Agriculture's Institute of Drug Control, in the country. Promote the use of) to prevent potato sprouting, with good results for many years. The method of use is: the potato is stored in the cellar and stored in the chamber for 10 to 15 days. After the injured wound is naturally healed and stored, the rotted lumps are rarely present. During the period from the healing period of the potato to before germination, the CIPC powder is applied to the potato heap. If the potato is stored in excess, it must be applied in a layered manner during heaping, and the sprout inhibiting agent will sublimate into gas. To suppress the bud effect. After spreading the pesticide, immediately cover the potato heap with rags for 3 days to 5 days, and then remove the tarpaulin. You can also use a duster to spray on the potato stack, which will have a more pronounced inhibitory effect. Use a dose of 2.5% of effective powder, apply 400 to 500 grams per ton of potato, effective suppression period of up to 60 days; apply 800 to 1000 grams of bud inhibiting agent per ton, long-term storage, anniversary supply market. In order to reduce the input of potatoes, according to the market demand for potatoes, the dosage of pesticides can be controlled flexibly to achieve the best effect of inhibiting buds. The anti-budding agent belongs to an efficient, low-toxicity, low-residue medicament with a large safety factor. The potato can be eaten at any time after spraying budding inhibitors, and it has no pollution to the pits or rooms storing potatoes and has no effect on human health. In the past few years, the use of potato in pits and rooms in the summer combined with the suppression of budding agents to suppress the germination and preservation of potatoes to meet the off-season supply of vegetables in the market, has achieved greater economic benefits, and can increase the value of 0.3 yuan per kilogram of potatoes grown in intercropping fields. Each mu can increase income 300 yuan.
