马铃薯具有产量高,生育期短,用途广的特点。适于贮藏运输,既可粮菜兼用,又是轻工业原料和出口物质,在城市蔬菜供应淡季,可调剂市场需要。春栽马铃薯是我省习用的主要栽培方式。在马铃薯生产中,除了因种薯退化影响产量外,也常因栽培技术不当,使产量不能提高。为了摸索增产的有效措施,1971-1972年我们进行了试验。 Potato has the characteristics of high yield, short growth period and wide use. Suitable for storage and transportation, both food and agriculture, but also light industrial raw materials and export substances in the urban vegetable supply off-season, adjustable market needs. Spring planting potato is the main cultivation method used in our province. In potato production, in addition to the degeneration of seed production affect the yield, but also often due to improper cultivation techniques, so that the yield can not be increased. In order to explore effective measures to increase production, 1971-1972 we conducted a test.
