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。
Beet standardized cultivation technology system, with the optimal yield and sugar content and economic efficiency as the overall goal, comprehensive domestic and international research achievements and peasants beet cultivation of advanced experience, the systematic experimental study, combined with the demonstration area of large area Promotion of feedback correction, the formation of the beet yield of 2-3 tons, the sugar content of about 19.5% of live beet and paper tube seedling transplanting beet standardized cultivation of technical specifications, the beet cultivation management into the index, quantitative, quantitative The level of the stage. The practice of 1986 to 1988, the promotion of an area of 78933.2 acres, an average yield of 2.040 tons, the rate of 15.85% sugar, yield increased 47.8%, 1.20% increase in sugar, of which 1.953 tons of live beet per mu, Planting 2.750 tons per mu, industry and agriculture a total increase of 9.96 million yuan in economic benefits.
