甜菜规范化栽培技术体系的研究

The Study on the Standardization System of Siigarbeet Cultural Technics

甜菜规范化栽培技术体系,以最佳产量和含糖率及经济效益为总目标,综合国内外的单项研完成果及农民种植甜菜的先进经验,进行系统的试验研究,并結合各示范点大面积推广进行反馈修正,形成了亩产甜菜2—3吨,含糖率19.5％左右的直播甜菜和纸筒育苗移栽甜菜规范化综合栽培技术规程,使甜菜栽培管理进入了指标化、数量化、定量化水平的阶段。经1986～1988年的实践,推广面积78933.2亩,平均亩产2.040吨,含糖率15.85％,产量提高47.8％,含糖率提高1.20％,其中,直播甜菜亩产1.953吨,纸筒育苗移栽亩产2.750吨,工农业共增加经济效益996万元。

The standardization system of sugarbeet cultural technics has been developed based on various research results of sugarbeet cultivation and advanced experiences of sugarbeet farmers. In the areas of cultivation sugarbeet by following the indication of the system, the yield of 2—3t/ mu and sugar content of 16.5% were gotten. In the experiments of 1986—1988, the yield of 2.75t/mu was gotten with method of raising seedling in paper pot and the yeild of 1.953t/mu with traditional method. The total planting area in this experement is 78933.2mu. The net profit is 9.96 million yuan.
