    摘要
  • 摘要:
      目的  分析蚕豆（Vicia faba L.）花荚期疏枝的饲用和肥用成分，为合理利用蚕豆疏枝提供参考。
      方法  在田间试验条件下，测定11个蚕豆品种（系）的花荚期疏枝的生物量、养分含量及截获量。
      结果  花荚期蚕豆可疏枝2～3次，产生茎叶干物质1.22～2.54 kg·hm−2。作为饲草利用，蚕豆疏枝相对饲用价值介于96.79～120.23，从高到低依次为通蚕鲜6号＞陵西一寸＞I3＞通蚕鲜8号＞通蚕鲜10号＞通蚕鲜7号＞通09-110-1＞日本大白皮＞I2＞I1＞I4。依据等级划分可知，I3、通蚕鲜6号、通蚕鲜8号、通蚕鲜10号、陵西一寸属于二级偏上水平，通蚕鲜7号属于二级偏下水平，I1、I2、I4、通09-110-1、日本大白皮属于四级偏上水平。作为绿肥利用，蚕豆疏枝翻压回田可提供N、P、K截获量分别为43.79～75.20、6.52～13.95、61.91～120.69 kg·hm−2，相当于34.09～98.82 kg 氮、8.50～14.21 kg 磷、80.73～128.63 kg 钾的有效养分。
      结论  综合分析比较参试蚕豆品种（系）生物产量、品质及营养价值，认为在福建地区，I3、通蚕鲜6号、通蚕鲜8号、通蚕鲜10号、陵西一寸花荚期疏枝饲用价值较高；I2、I4、通蚕鲜8号、通09-110-1花荚期疏枝肥用价值较高。

     

    Abstract:
      Objective  Composition and value of the broad bean branches pruned at flower-pod stage to be used for forage or fertilizer were evaluated.
      Method  Pruned branches from 11 varieties of Vicia faba L. were collected in the field to determine the biomass, nutrients content, and NPK uptake of the waste material.
      Result  It was found that the broad bean plants could be pruned 2 to 3 times at the flower-pod stage to yield 1.22-2.54 t·hm−2 on dry matters. As forage, the branches had a relative feeding value ranging from 96.79 to 120.23 that ranked by the various varieties as Tongcan (fresh) No.6＞Lingxiyicun＞I3＞Tongcan (fresh) No.8＞Tongcan (fresh) No.10＞Tongcan (fresh) No.7＞Tong 09-110-1＞Ribendabaipi＞I2＞I1＞I4. Thus, I3, Tongcan (fresh) No. 6, Tongcan (fresh) No. 8, Tongcan (fresh) No. 10, and Lingxiyicun were classified as upper Grade-2 and Tongcan (fresh) No. 7 as the lower level of the same grade, whereas I1, I2, I4, Tong 09-110-1, and Ribendabaipi as upper Grade-4. To be used as green manure, the pruned branches could be buried in soil to provide nutrient uptake on N at 43.79–75.20 kg·hm−2, 6.52–13.95 kg·hm−2on P, and 61.91–120.69 kg·hm−2on K, which represented effective equivalents of 34.09–98.82 kg of N, 8.50–14.21 kg of P, and 80.73–128.63 kg of K on a per hm2 basis.
      Conclusion  The biomass yield, quality, and nutritional value of the pruned branches of the broad bean variety I3, Tongcan (fresh) No. 6, Tongcan (fresh) No. 8, Tongcan (fresh) No. 10, and Lingxiyicun in the province had high values as forage, and I2, I4, Tongcan (fresh) No. 8, and Tong 09-110-1 high as fertilizer.
