Abstract:In yellow river irrigation areas of middle Gansu province,effects of different water supply conditions on yield and water production effect of processed potato cultivar Atlantic were studied. The results showed that yield of processed potato was significantly increased by increasing irrigation quantity and times from squaring period to flowering period;On the basis of adequate water supply in flowering stage, increased irrigation quantity moderately from final flowering period to mature period, it is beneficial to improve potato yield and water use efficiency. Under the condition of water and fertilizer integration, the suitable water management mode of processed potato cultivar Atlantic is that irrigated water volume was 2 400 m3/hm2 and irrigated 16 times from squaring period to flowering period, irrigated water volume was 900 m3/hm2 and irrigated 6 times from final flowering period to mature period. Under this water management mode, the number of tubers per plant and the weight of tubers increased significantly, which increased by 2.02%~16.91% compared with other treatments, and the commercial property of potato tubers was relatively optimized.

蔬菜產业是张掖市农业增效、农民增收的支柱产业之一[1 - 2 ],2018年,全市各类蔬菜播种面积达到5.59万hm2,约占农作物播种面积的19.2%,总产量310万t,总产值40亿元[3 ]。进入21世纪以来,张掖市充分挖掘和发挥自然条件优越、市场前景广阔、运销网络健全、生产技术先进等有利因素,抢抓“一带一路”倡议机遇,蔬菜产业进入了快速发展阶段。种植基地面积稳步扩大,标准化程度逐步提高,市场体系逐步健全,目前产品已远销广东、浙江、上海等23 个省市,部分出口中亚、东南亚国家和我国的港、澳地区[4 ]。设施蔬菜、高原夏菜、脱水蔬菜生产在西北地区乃至全国拥有较高的知名度,生产水平、产品质量均位居全省前列。
1 张掖市蔬菜产业发展的技术瓶颈
张掖地处河西走廊中段,农业生产水平总体上在甘肃省属于领先水平。但是随着近年来农业生产组织方式发生变化,土地流转经营对农业生产提出了新的要求,加之蔬菜产业具备的劳动密集型、资金密集型、技术密集型等产业特点,张掖市发展蔬菜产业要进一步科学布局、合理规划,逐步形成设施果菜进滩、喜寒蔬菜上山、喜温蔬菜入川的生产格局。……
