通过在高、中、低产田的施肥试验，探讨了水稻品种天丰优101的养分吸收特征。结果表明：天丰优101对氮反应最敏感，对磷反应较敏感；天丰优101籽粒的含氮和含磷量均高于茎秆的，而茎秆的含钾、含锌量则均高于籽粒的；在养分供应平衡条件下籽粒与茎秆各养分含量均较高；天丰优101对N、P2 O5、K2 O吸收量的比例，低产田为1．00∶0．36∶1．63，中产田为1．00∶0．42∶1．81，高产田为1．00∶0．44∶1．81；在该品种中，氮的运转率为61．5％，磷的运转率为62．0％，钾的运转率为15．6％，锌的运转率为36．6％。

The nutrient uptake characteristics of rice new variety Tianfengyou 101 were studied through fertilization tests in high-yielding, middle-yielding and low-yielding paddy fields .The results showed that Tianfengyou 101 was the most sensitive to ni-trogen, and more sensitive to phosphorus .The seed of Tianfengyou 101 contained higher nitrogen and phosphorus than the stalk of this variety , while the latter contained higher potassium and zinc than the former .Under the condition of balanced nutrient supply , the contents of various nutrients in both seeds and stalks were higher .The amount proportion of N , P2 O5 and K2 O absorbed by Tian-fengyou 101 was 1.00∶0.36∶1.63 in low-yielding field, 1.00∶0.42∶1.81 in middle-yielding field, and 1.00∶0.44∶1.81 in high-yielding field.In this variety, the transportation rate of nitrogen , phosphorus, potassium and zinc was 61.5%, 62.0%, 15.6%, and 36.6%, respectively.
