Abstract:
      To overcome constraints such as rigid restrictions, salinization and tuber easily deformed green top, facing potato production in Qinwangchuan irrigation area, planting pattem, variety,water-saving irrigation techniques and planting techniques were investigated in the study, key techniques for potato production in Qinwangchuan were as follows, 75 cm width with a large ridge mulching cultivation,use of early-maturing varieties of LK99, 50 g virus-free potato seed about 1 small whole potato, sown early in April, 4 500 points/667m2, the whole growth period in four irrigation 160 m3/667m2, growing season topdressing 5~10 kg 50% potassium, 2 000 kg goods of potato can be obtained in 667 m2. Potato industrial production in Qinwangchuan can be realized by carrying out early mature cultivation a large ditch and high ridge mulching soil cultivation mode.
