摘要
通过田间试验,研究了施用硼、锌和钼肥对紫云英种子产量、根瘤菌数量的影响。结果表明:与不施硼、锌和钼肥处理相比,施用硼、锌和钼肥处理的紫云英种子产量提高13.7%～38.9%,且差异均显著(P<0.05);主要因单株结荚数和每荚种子粒数等产量构成因素提高,施用硼、锌和钼肥处理的单株结荚数和每荚种子粒数分别提高18.9%～44.3%和21.4%～33.3%,均达显著差异(P<0.05)。施用硼、锌和钼肥可以促进紫云英根瘤的形成,施用硼、锌和钼肥处理紫云英根瘤数增加2.1%～82.4%。施用钼肥处理紫云英的种子产量、经济性状和根瘤数量均高于未施钼肥处理。说明紫云英生长发育及种子产量形成对钼的敏感性高于其它微肥种类。
A field experiment was conducted to study the effects of applying B, Zn and Mo on seed yield and the number of rhizobia of the Milk vetch in hilly upland red soil. Compared to no B, Zn and Mo fertilizer treatment, applying B, Zn and Mo fertilizer could increase the seed yield of Milk vetch signicantly by 13.7% to 38.9% （ P 〈 0.05 ） ; The main reasons due to the result was the increasing of the number of single plant pod and seed grains per pod, which increased by 18. 9% to 44. 3% and 21.4% to 33.3% （P 〈0.05）, respectively. Additionally, applying B, Zn and Mo fertilizer could increase the amount of Milk vetch rhizobium by 2. 1% to 82. 4%. The seed yield, economic characters and the number of rhizobium of applying molybdenum fertilizer treatments were better than the one without it, which indicated that the growth condition and seed yield form of Milk vetch was more sensitive to Mo than to B or Zn.
