我县甜菜种植面积由1981年的三万亩到1983年实播面积发展为八万多亩。但从目前生产水平看产量、质量一直较低,平均亩产仅在一吨左右,含糖率也仅在15％左右。如何从技术措施方面提高产量和质量,增加经济收益,从1981年起我们应用黑龙江省石油化学研究所研制的新型植物激素——三十烷醇在甜菜上进行试验,从中筛选出最佳的施用浓度和施用方法,肯定了三十烷醇的增产、增糖效果。三年来,从小区试验到大面积生产示范(1982年示范面积700亩,1983年施用面积三万多亩),均收到了良好的增产增糖效果。
My county beet cultivation area from thirty thousand acres in 1981 to 1983, the actual sown area of 80,000 mu. However, from the current production level of output, the quality has been low, with an average yield of only about one tonne, with a sugar content of only about 15%. How to improve the yield and quality from the technical measures and increase the economic benefits? From 1981, we applied the new plant hormone-triacontanol, developed by Heilongjiang Institute of Petrochemical Technology, to test on sugar beet to select the best application Concentration and application methods, affirmed the triacontanol production, increased sugar effect. In the past three years, a series of experiments have been carried out, ranging from community experiments to large-scale production demonstrations (demonstration area of 700 mu in 1982 and 30,000 mu of acreage in 1983).
