摘要
为解决西北寒旱区马铃薯全膜覆盖种植模式下,由于放苗不及时产生的高温烧苗等问题,结合国内外研究现状,解析了膜土系统温度场特征、幼苗高温胁迫响应机制、作物生长力学及应力作用下生长行为;研究了作物生理生化特性、膜顶坐土、种子播前预处理对作物自动破膜能力的影响;提出了从生理生化特性、膜土苗力学系统和播前预处理等方面提升种薯自动破膜出土成苗能力的措施,以期为西北寒旱区构建高产、高效的机械化马铃薯栽培技术体系提供理论和实践依据。
In order to solve the problem of potato seedlings getting burnt due to high temperatures because of delayed seedling release under a full film mulching mode in in cold and arid areas of northwest China,coupled with the research status both at home and abroad,the characteristics of temperature field in membrane soil system,seedling response mechanism under high temperature stress,crop growth mechanics and growth behavior under stress were analyzed.The effects of physiological and biochemical characteristics of crops,coating on soil and pretreatment of seeds before sowing on automatic film breaking ability of crops were studied.In order to provide a theoretical and practical basis for the construction of a high-yield and high-efficiency mechanized potato cultivation technology system in cold and arid areas of northwest China,measures to improve the seedling capacity of seed tubers were proposed from the aspects of physiological and biochemical characteristics,membrane soil seedling mechanics system and pre-sowing pretreatment were put forward.
