| 中文摘要: |
| 针对秦王川灌区土壤僵硬、盐碱化的限制及薯块易变形绿头等制约因素,进行了栽培模式、品种、节水灌溉技术、播种技术的研究。通过田间试验得出秦王川灌区马铃薯生产的关键技术:采用75 cm宽度的大垄覆膜覆土栽培,选用中早熟品种LK99,用脱毒种薯一级良种50 g左右小整薯,4月初播种,4 500穴/667m2,全生育期分4次灌水160 m3/667m2,生长期追施510 kg/667m250%硫酸钾,商品薯产量可达到2 000 kg/667m2以上。秦王川灌区马铃薯生产以早熟栽培为主,采用大沟高垄全生育期覆膜覆土栽培模式,可实现产业化生产。 |

| 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. |
