There are skills to prevent potato sprouting during storage.
To prevent potato sprouting during storage, the field can be sprayed with 2~3g/kg in the late growth stage (that is, 2-3 weeks before harvest), or the whole plant can be sprayed with 2,4,5-ray T at the concentration of 0.5~1g/kg one week before harvest to prolong dormancy and storage period. In the later stage of growth, spraying the whole plant with the mixture of 3g/kg and 2,4 and 5m T of 0.3g/kg was more effective in preventing sprouting. In addition, after the potato is harvested, the

Causes and Prevention of Potato decay during Storage
Potato is one of the main crops in Qinghai province, which has the characteristics of high and stable yield, short growth period, strong adaptability, rich nutrition, both grain and vegetable, and high economic utilization value, so it is deeply welcomed by the general public. In recent years, with the development of potato industry, significant production benefits have led to the expansion of potato planting area year by year. However, due to the extensive scientific management of potato during production, harvest, transportation and storage, a large number of seed potatoes rot during storage. According to the survey in recent years, most of the Naoshan areas in Qinghai Province

Storage management of potato
The summer harvest of potatoes is in the high temperature season, and the potato pieces after harvest can be stored in a cool and ventilated room, cellar or shade shed. The potato pile is generally no more than 0.5m and no more than 2m wide. Put an appropriate amount of ventilation pipes in the heap for ventilation and cooling, and cover the light with straw curtains. During the pre-storage period, according to the weather conditions, we should often check and remove rotten potato chips. 1. Potatoes were harvested in Lvda area of Liaoning Province in mid-July and stored in shady sheds or empty houses until October. The depth of the trench is 1-1.2 m and the width is 1-1.

Potato sprouting prevention during storage
To control potato sprouting during storage, 2000-3000ppm penicillin could be sprayed in the field in the late growth stage, and the whole plant could also be sprayed with 2,4,5-1000ppm 2,4,5-1000ppm one week before harvest to prolong the dormancy and storage period. Spraying the whole plant 2-3 weeks before harvest with 3000ppm and 300ppm's 2,4,5-murT had a better effect in preventing germination. In addition, after the potato harvest, methyl naphthyl acetate was sprayed on the dry soil, and then

Storage and fresh-keeping Technology of Potato
Potato is a vegetable with dormant period, summer storage does not need cooling, but to prevent stacking heat. The specific method is: pile the non-injured high-quality potato blocks in a well-ventilated house or ventilated storage, the heap height is not more than 0.5 meters, in order to prevent the heat injury of the potato blocks in the pile, set up a ventilator every 1 meter, if the baskets are stacked, it is best to form a "well" shape to facilitate ventilation. During storage, regular tipping inspection should be carried out to remove infected potatoes in time to prevent the spread of germs. In order to prevent potato pieces from sprouting during storage, one can be used.

Symptoms and Control methods of main Diseases of Potato
1. Late blight 1. Symptoms identify that the disease is a fungal disease, which harms stems, leaves and potato tubers. brown water-stained spots appear in the damaged parts of stems and leaves, and then expand into black patches. When wet, there is a circle of white mildew around the disease spot, and the back of the leaf is very obvious. after the potato block is damaged, brown or blue disease spot occurs at the initial stage, and then expands, the surface is gradually sunken, and the potato meat in the lower layer of the disease turns brown. 2. The selection of resistant varieties is the most economical and effective way to control late blight, such as Wushu 8, 9, 11, Longshu 3 and 5.

Problems and Countermeasures in Potato planting
The perennial planting area of potato in Yutian County is 70,000 mu, and the yield per mu is generally 2500-3500 kg. Most potato growers have some experience and good methods in cultivation and management, but on the whole, there are still many problems in potato cultivation and management. it is summarized as follows. The main results are as follows: 1. after continuous planting for several years, the potato often appears dwarfing, clumping, weak growth, shrinking, smaller, brittle or ringed spots, dark brown veins, leaves easy to fall off, and serious withering of the whole plant.

Technical guidance of potato planting
Select tubers with neat potato shape and delicate and smooth skin as seed tubers. The method of disinfection and disinfection is to mix 200 parts of 40 ‰ formalin with water, spray potato pile or seed potato for 5 minutes, cover with film and steam for 2 hours, then spread it into a thin layer, ventilate and dry. The cutter should also be sterilized. The whole potato planting selects the robust whole potato planting, which can prevent the disease infection, give full play to the top advantage, and ensure the good effect of the whole seedling. Sprouting is sometimes imperative in order to save seeds and break dormancy. The weight of the cut piece is 25g.

Skills of planting, managing and harvesting potatoes
(1) selecting and fertilizing the sandy loam with deep soil layer and loose and fertile soil, ploughing and crushing the soil and cultivating it after leveling. Potato needs a large amount of fertilizer in the early and middle stages of growth. In order to ensure normal growth and development, base fertilizer must be re-applied. Generally, 2500-3000 kg of farm manure, 50 kg of phosphate fertilizer and 15 kg of potash (or 100-200 kg of plant ash) are applied per mu. Nest or furrow application is carried out when transplanting. (2) sowing 1. Select improved varieties: it is appropriate to choose high.

Prevention of Potato poisoning
Potato is rich in soluble carbohydrates and has good digestibility for all kinds of livestock, and the nutrition of raw and cooked feeding is basically similar. However, the stems, leaves and tuber kernels of potatoes all contain toxic substances, so feeding should be more cautious. Potatoes contain more non-protein nitrogen, accounting for about half of crude protein, among which there is a nitrogen-containing substance called solanine, which is toxic. The content of this substance is the highest when the tuber is immature and germinated, and it is generally the most in the turquoise skin and bud eye of the stem, and there is more nitrate in the stem and leaf, which will cause the intestine after the livestock are collected and fed.

Starch for potato reagent
Starch for reagent can be prepared from potato with low cost and high economic benefit. Production method 1. Washing and making potato pulp: wash the potatoes with water for 2 or 3 times, remove all the mud and sand, and cut off the potatoes with hoes and rotten holes. Turn on the crusher, put in the washed potato pieces and flow out the potato pulp immediately. Because the fresh potato itself contains about 75% water, there is no need to add water when beating. two。 Filter powder and starch rinsing: the potato pulp is filtered by machine or manually, and the starch milk (water containing starch) is stored in the pool to clarify.

Potato dregs can be made into protein feed
Recently, researchers at Harbin Institute of Technology have made gratifying progress in the production of single-cell protein feed from waste potato dregs. The researchers not only screened out the excellent strain combination for producing cell protein, but also designed and formulated a complete technological route for the production of single-cell protein feed from potato dregs. The production of cellular protein by liquid fermentation by adding juice to potato dregs is proposed and applied for the first time at home and abroad. China produces more than 7000 million tons of potatoes annually and processes more than 3.4 million tons of starch surplus potato dregs.
