甜菜露地越冬采种种子产量的高低,质量的优劣不仅受其本身遗传因素的制约,也受环境的影响。现根据试验结果从栽培技术方面入手,试论提高我区甜菜露地越冬种子产量和质量的有效途径。一、不同土质对甜菜露地越冬采种产量和质量的影响我区土壤以淤土、砂淤两合土、砂碱土、砂僵黑土为主。试验资料表明,各类土壤对种 Beet harvest winter seed production level, quality is not only affected by its own genetic factors, but also affected by the environment. Based on the test results from the cultivation techniques to start, try to improve my area beet seedling winter yield and quality of effective ways. First, the impact of different soil on the winter harvest of sugar beet yield and quality I soil silt, sand and silt two soil, sand alkaline soil, sand black soil dominated. Test data show that all kinds of soil on the species
