１９８９～１９９０年在甘肃省河西走廊灌区的３个县（市），研究了甜菜种植密度、氮、磷用量栽培因子对甜菜间作套种后的产质量及亩产糖全的影响。并建立了相应的实用数学模型，经计算机模拟综合进优得出了河西灌区甜菜小麦间作套种的栽培模式及主要技术规范。经大田生产验证，可获取亩产２５０～３６０ｋｇ小麦、２．５～３ｔ甜菜（含糖率１７％以上），本项研究为粮糖双丰收开辟了新途径。 From 1989 to 1990, the effects of planting density, nitrogen and phosphorus fertilizing factors on the yield and quality of sugar beet after interplanting were studied in three counties (cities) of Hexi corridor irrigation area in Gansu Province. And established the corresponding practical mathematical model. Through computer simulation, the cultivation pattern and main technical specifications of beet intercropping were obtained. After verification of field production, 250-360 kg of wheat per mu and 2.5-3 tons of sugar beet (containing more than 17% of sugar content) can be obtained. This research has opened up a new way for double harvest of grain sugar.
