摘要
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。
Through deterntining soil exampls isoils contain Zn about 0.20-1.10 ppm (meaning 0.39ppm), signifying lack of Zn. The subject studied the regularity of beet absorpting Zn in every growing period and the Zn distribution in every parts of plant. The applying Zn fertilizer have effects on both beet accumulating dried substance and beet yield-quatity. The test result showed (in 1988-1990), applying Zn fertilizer can increase yield 16％(mean), sugar content 0.7％, sugar yield 16%, and strengthen a dear disease resistance to plant.
