摘要
测定11个功能叶片含钼量在0.15—1.30ppm,84个土壤有效钼含量在0.01—2.87ppm,41个子实钼含量0.10—12.15ppm。在中部中性、东部酸性土壤上有效钼0.30ppm以下,种子含钼2.30ppm以下钼酸铵拌种有效,高含量时无效甚至减产,种子拌钼能提高子实钼的含量。西部石灰性土壤、子实含钼量均较低,钽钼酸铵拌种效果不稳定,种子拌钼不能提高子实钼的含量,用含钼较高2.06ppm以上大豆种子比用0.53—0.90ppm的种子增产5.5—23.9％。
11 functional leaves and 41 samples of soybean seeds were analysed, the content of molybdenum was 0.15-1.30ppm and 0.10-12.15ppm respetively. 84 samples of soil were detected , the content of available molybdenum was 0.01-2.87ppm. The content of molybdenum was below 2.30ppm in seeds and the content of available molybdenum was below 0. 3ppm in neutral soil in the middle part and acid soil in the east part of Jilin province. Seed dressing with ammonium molybdate was effective and increase yield, but the content of molybdnum was high in seed and soil, seed dressing was not effective even reduced yield, seed dressing with molybdenum can improve content of molybdenum in the seed. In the calcarlous soil in the west part of Jilin province, the content of molybdenum all was low in seed, the effectiveness of seed dressing with ammonium molybdate was not stable and could not improve the content of molybdenum in seeds. The yield of soybean seed with over 2.06ppm molybdnum was higher than soybean seed with 0.53-0.91ppm molybdenum, the yield can increase 5. 5-23. 9%.
