1986年宁夏甜菜糖业研究所在国营连湖农场的协助下,在该场二队、六队进行了甜菜大面积高产高糖综合栽培技术示范。取得了显著成效,520亩甜菜平均含糖17.2％,比上年提高1.6度;平均亩产3756公斤,比农场其它六个队高583公斤,增产18.37％。综合栽培技术措施是:1.选择适宜种植甜菜的土壤。示范地为灌淤土,土层深厚疏松,地下水位低,灌排畅通,前茬为春小麦,麦收后伏耕。秸杆还田。土壤耕层(0—25厘米)含有机质1.72％,速效氮62.37ppm,速效磷22.62ppm,全盐0.15％,pH值8.5,盐碱较轻,肥力较高。
In 1986, under the assistance of the state-owned Lianhu Farm, Ningxia Beet Sugar Research Institute conducted a demonstration of a large-scale, high-yield and high-sugar comprehensive cultivation technology of beet in the No.2 and No.6 teams of this field. Significant results have been achieved. The average sugar content of 520 acres of beets is 17.2%, an increase of 1.6 degrees over the previous year. The average yield per mu is 3756 kilograms, 583 kilograms more than the other six farm farms, an 18.37% increase. Integrated cultivation techniques and measures are: 1. Select the appropriate planting sugar beet soil. Demonstration for irrigated soil, deep and loose soil, low groundwater level, irrigation and drainage flow, the former crop is spring wheat, wheat harvest after tillage. Straw to the field. Soil topsoil (0-25 cm) contains 1.72% organic matter, available nitrogen 62.37ppm, available phosphorus 22.62ppm, all salts 0.15%, pH 8.5, saline and light, high fertility.
