Recently, the sweet potato harvest season, the sweet potatoes from all over the country have their own characteristics, the new varieties and new technologies introduced today will let you discover that there are so many magical places in the small sweet potato. 1, potato 17 A variety of starch, edible and food processing multi-purpose varieties of 17 genera. Good germination, medium and long vine; potato-shaped spindle, red-skinned orange and yellow meat, concentrated in potato, tidy potato, about 4 potatoes per plant, high rate of large and medium potato; excellent taste; more storage-resistant; The drying rate is 34.97%, the starch rate is 24.06%; the high resistance to vine disease, the middle resistance to black spot, the medium resistance to stem nematode, and the root rot. In 2012, in the regional trial of the national sweet potato variety in the Yangtze River Basin, the average fresh potato yield was 2440.1 kg, the dried potato yield was 860.4 kg, and the starch yield was 593.3 kg. In the 2013 district trial, the average fresh potato yield was 2356.6 kg, the dried potato yield was 816.6 kg, and the starch yield was 560.4 kg. In the 2014 and 2015, Shanshu 17 passed the identification of new sweet potato varieties in Chongqing and the country. The new sweet potato variety, Shanshu 17 has a high yield of fresh potato and starch. It has excellent taste and good taste and beautiful potato shape. It can be used as a special product for starch processing, high-quality edible fresh-selling and food processing. 2, æ¸ purple potato 7 æ¸ç´«è–¯7 is a purple sweet potato variety for food and food processing. Excellent germination, medium and long vines. Potato-shaped spindle, purple red skin purple meat, concentrated potato, potato lumps are relatively neat, about 3 potatoes per plant, high medium and high potato rate, excellent taste; storage resistance; resistance to stem nematode, root rot and dark spots disease. In the 2010, 2012 and 2014, æ¸Zishu 7 participated in the regional experiment of the northern potato area, the Yangtze River basin and the southern potato area. The average fresh potato yield was 1581.7, 2179.79 and 1757.14 kg/mu, respectively. In the first or second variety, the anthocyanin contents were 16.69, 20.86 and 20.86 mg/100 g, respectively. æ¸Zishu 7 was identified in 2012 and 2014 by the national and Chongqing sweet potato varieties, which can be used as high-quality edible fresh food and food processing special varieties. 3. High-yield starch-type sweet potato new variety “æ¸è‹8†A new high-yield starch-type sweet potato variety jointly selected by Chongqing Sweet Potato Engineering Technology Research Center of Southwest University and Food Crop Research Institute of Jiangsu Academy of Agricultural Sciences. Characteristic advantages: In the 2006-2007 biennial national sweet potato regional trials in the sweet potato region of the Yangtze River Basin, the average fresh potato, dried potato and starch production ranked first. Technical indicators: In the 2006-2007 biennial sweet potato regional trials in the Yangtze River Basin, the average yield of fresh potato is 2414.6 kg, ranking first; the yield of dried potato is 699.0 kg, ranking first; the yield of starch is 460.0 kg. Ranked first. In the potato block, it resists black spot disease and resists root rot. The average dry matter rate is 29.2%, the average starch rate is 19.1%, and the cooked food quality is good. 4. A new potato harvesting and collecting device The invention relates to a novel potato harvesting and collecting potato device, which comprises a detection, a control, a hydraulic device and a pulley assembly, a potato collecting box and a frame. The wall of the potato box is fixed on the frame, the bottom of the movable box is placed obliquely in the wall of the box, and the discharge port is arranged at the bottom of the rear side of the box wall; the photoelectric sensor in the detecting device is installed at the upper edge of the left and right sides of the box wall , each set is equipped with a protective cover, and the position sensor is installed between the bottom of the movable box and the frame; The fixed pulley in the pulley assembly is fixed on the frame, the movable pulley is fixed on the protruding end of the hydraulic cylinder, the hydraulic cylinder is installed on the frame below the collecting box, one end of the wire rope is connected with the bottom of the movable box, and the other end is fixed on the frame; The unit is installed in the cab. The invention can automatically control the drop height of the potato within a safe range, effectively solve the problem of the potato scar when collecting the potato, and the bagging is convenient, and the working intensity of the driver can be greatly reduced.
