| 摘 要： | 皖油10号不同施硼水平田间试验结果表明，苗期各器官NPK含量、蕾薹期各器官PK含量、盛花期花蕾和茎NP含量及各器官含B量、成熟期角果和籽粒含K量均随施B量增加（0～0．6mp／kg）而升高，再增加施B量，各元素含量均下降。籽粒NPB含量亦如此，其最大施B量为0．7mg／kg。蕾薹期和盛花期各器官含B量及叶含N量、花蕾含K量均随施B量增加而升高，而苗期植株含B量和盛花期根含N量、茎叶含K量却相反。不同生育期各元素分布是地上部分＞根，其地上部分在盛花期各元素分布是花蕾＞叶＞茎；在成熟期NP主要集中于籽粒，角果次之；KB主要集中于角果，籽粒和茎次之。

| Abstract: | A field experiment with applied different amount of boric fertilizer on Wanyou No.10 was conducted. The results indicated as follow: The contents of N,P,K in all organs in seedling stage, P, K in all organ in stem eongation stage, N, P in flower and stem and B in all organs in flowering stage, and K in pods and grains in ripening stage increased with the increase of boric fertilizer level (0-0.6mg/kg), but they dropped by over 0. 6mg/kg boric applied. The contents of N,P,B in grain had the same trends (with applied 0-0. 7 mg/kg B).The contents of B in all organs in stem eongation and flowering stage and N in leaf and K in flower in flowering stage increased alone with the increase of B level, but the content of B in all organs in seedling stage, N in root in flowering stage and K in stalk and leaf were contrary. The distribution of the all elements in all organs was arenal parts>root,that was flower>leaf>stem among the aerial parts in flowering stage. In ripening stage, the contents of N,P in grains and B in pods were higher than that of other parts. |
