双城县是黑龙江省种甜菜的老区,有70多年的历史,历年种植甜菜面积10万亩左右,占全县总耕地面积2.8％。近十年来,甜菜块根产量和含糖率呈大幅度的下降,形势对发展生产十分不利。为了改变这种局面,1985年,我们在双城县四个村的4059亩的土地上,采用了综合栽培技术的治理措施,平均亩产块根1237公斤,比对照提高49.9％,含糖提高0.6度以上。初步取得了治理的效果。主要的栽培技术措施:①合理密植:据以往各地调查,一般每亩收获株数平均为2323.5株,与正常要
Shuangcheng County, Heilongjiang Province is the old beet species, 70 years of history, years of planting about 100000 acres of beet, accounting for 2.8% of the total cultivated area of the county. In the past ten years, the root yield and sugar content of beet have dropped drastically. The situation is very unfavorable to the development and production. In order to change this situation, in 1985, we adopted the comprehensive cultivation techniques on the 4059 mu of land in the four villages of Shuangcheng County, with an average of 1,237 kilograms per mu of roots and tubers, 49.9% more than the control and an increase of 0.6 Degree above. Initially achieved the effect of governance.
