土壤测定结果表明:土壤中有效锌含量一般为0.20—1.10ppm,平均0.39ppm,属缺锌土壤。本项目研究了甜菜不同生育期吸收锌的规律及在不同部位的分布状况;施锌后对甜菜积累干物重以及对甜菜产质量的影响。1988—1990年试验结果表明:施锌后可使块根平均增产10%;含糖率提0.7%;产糖量增加16%左右。且可明显增强植株抗病能力,甜菜褐斑病发病率降低1级。
Soil determination results show that: the effective zinc content in the soil is generally 0.20-1.10ppm, an average of 0.39ppm, is a zinc-deficient soil. The project studied the beet zinc absorption during different growth stages of the law and in different parts of the distribution of zinc after the accumulation of sugar beet dry weight and the impact on the quality and yield of sugar beet. The experimental results from 1988 to 1990 showed that after rooting zinc, the average root tuber yield increased by 10%, the sugar content increased by 0.7%, and the sugar yield increased by about 16%. And can significantly enhance the resistance of plants, the incidence of beetle leaf spot decreased by one.
