Preparation of flaky mashed potatoes
1. Production process potato → cleaning → peeled → slices → pre-cooking → cooling → cooking → grinding → dry → crushing → packaging → finished products. two。 Main points of production (1) raw materials are selected to remove germinated and green potatoes and rotten and diseased potato pieces. If there is sprouting or turning green, the germinated or green part must be cut off or completely removed before it can be used to ensure that the content of solanine glycosides in potato products does not exceed 0.02%, otherwise it will endanger personal safety.

Control Methods of Potato Diseases
1. Late blight (1) Conditions of incidence. Potato late blight, also known as blight or potato plague, is a devastating disease of potato. In low-lying, poor drainage, field moisture, or excessive nitrogen application of the plot, the disease is more serious. When the temperature and humidity are appropriate, late blight spreads rapidly and the diseased plants die in pieces. (b) Symptoms. At first, round or irregular dark green spots appeared on the tip and edge of the diseased leaves, which became brown large spots after expansion. When the humidity was high, a circle grew at the junction of the diseased part and healthy part.

Key points of Potato cultivation techniques
1. Preparation before sowing: in mid-February, prepare agricultural materials such as seed potatoes, pesticides, chemical fertilizers and agricultural films. Take the seed potatoes out of the basement and put them indoors at about 12 degrees Celsius to sprout. 2. Cut a good seed potato: make sure that each seed potato has at least 1 color 2 bud eyes and weighs about 30 grams. The chopped seed potato pieces were mixed with medicine. The formula of the powder is to add 250 grams of 70% methyl topiramate wettable powder with 50 kg of fossil powder. 3. Timely early sowing: generally sowing from March 5 to 15, row spacing 90 cm, plant

Technical methods of Potato cultivation
First, catch early before snatching and get ready. The first is the choice of stubble, the first stubble is corn and wheat, the second is soybean and sorghum, and the beet stubble is the worst. The second is the selection of plots, such as soft soil, high content of organic matter, deep soil layer, drought and waterlogging resistance, good fertilizer and water conservation, and suitable for tuber growth. The third is to straighten the ground, the main depth is about 25 cm, so that the leveling and raking fine, the upper solid and lower virtual, is conducive to the formation of tubers, good stem shape, and increase the yield. Fourth, rational fertilization, and organic fertilizer is the main base fertilizer.

Techniques of raising Potato seedlings
Potatoes like a cold climate. Seed potato is often used as sowing material in production, but seed is also used for sowing production. For potato seed breeding, the suitable temperature for seed germination is 21 ℃ 23 min, which can begin to germinate in 5 days, while at lower temperature, it takes about 10 mi 20 days to prolong germination time. -the sowing rate is 5ml / mu, and the seedling age is about 60 days. The management is basically the same as eggplant fruit vegetables. The main seedling breeding methods of seed potato (tuber) are whole potato propagation, slicing propagation, seedling dissolving propagation and so on. Potatoes

Potatoes and sweet potatoes should be stored in separate cellars
Although sweet potatoes and potatoes are potato crops, they are different. The growth of the two and the suitable temperature for potato storage were obviously different. When storing sweet potatoes, in order to prevent invading sweet potatoes such as black spot and soft rot, after entering the cellar, the pit temperature is generally raised to 34 ℃ ~ 37 ℃ and the relative humidity is about 85%, and lasts for about 4 days, so that the wounds caused by potato blocks during excavation can be healed as soon as possible to prevent infection, which is called high temperature healing in production. After that, the pit temperature is generally controlled at 10 ℃ ~ 15 ℃, and the relative humidity

"five attentions" in the introduction of Potato
Most of the potato seeds are transferred back from other places, which is actually an act of introduction. When adjusting and purchasing seeds, it is necessary to understand the factors such as latitude, altitude and climatic conditions of potato seed stem producing area, and correctly select the producing area and variety according to the introduction law of potato. Pay attention to latitude and altitude. It is easy to succeed when introduced from high altitude to low altitude and from high latitude to low latitude. The reason is that the temperature is lower during the growth of potato at high altitude and high latitude, and the virus of potato seed stem is lighter and degrades slowly, which leads to planting at low altitude and low latitude.

Techniques of Potato Bud planting
Potato bud planting is according to the characteristics of potato with multiple bud eyes, so that each bud eye seedlings transplanting, to achieve multi-propagation, rapid propagation, to ensure the species nature of the variety. The propagation of bud planting technique can effectively prevent the occurrence of potato ring rot, increase the yield and starch content, put it on the market earlier, and save the amount of seed potato. First, the seed potato which is healthy and disease-free and has fully passed the dormant period is selected as the sprouting material. Second, select the land with leeward and sunny, good soil moisture, if the greenhouse cultivation needs to be carried out.
