研究羽叶决明(Chamaecrasta nictitans)代木栽培鸡腿菇(Coprinus ovatus)对其绝对生物学效率、基物失重、呼吸消耗及木质纤维素转化的影响.结果表明,羽叶决明牧草替代60%木屑(A60)栽培鸡腿菇的绝对生物学效率最高,均为10.77%.覆土前和采收后的基物失重和呼吸消耗都以A0(CK)为最高,分别为11.47%、11.47%和31.75%、25.55%,其木质素转化率也最高,为79.21%;纤维素转化率以A100(羽叶决明牧草替代100%木屑)为最高,达50.93%;半纤维素转化率以A40(羽叶决明牧草替代40%木屑)为最高,为49.74%.回归分析结果表明,绝对生物学效率和半纤维素转化率与替代比例呈抛物线相关,而基物失重、呼吸消耗及木质素、纤维素转化率与替代比例呈线性相关. 相似文献

羽叶决明代料栽培金福菇的研究 总被引：3，自引：0，他引：3
研究了羽叶决明（Chamaecrasta nictitans）替代培养料中的麦麸栽培金福菇（Tricholoma lobayense）对金福菇绝对生物学效率,C、N、P、K利用率,培养料失重率,木质素和半纤维素的降解率及呼吸消耗的影响。试验结果表明：羽叶决明替代40％的麦麸栽培金福菇,其绝对生物学效率,N、K、C素利用率及培养料失重率最高,分别为14．51％、27．71％、35．18％、11．60％和52．04％;而羽叶决明替代100％的麦麸时,呼吸消耗、木质素和纤维素的降解率最高,分别为40．60％、69．44％和72．42％。回归分析结果表明,绝对生物学效率,C、N、P、K利用率和半纤维素的降解率及培养料失重率与羽叶决明替代量呈抛物线关系,而木质素、纤维素的降解率和呼吸消耗与羽叶决明替代量呈线性关系。 相似文献

氮素对羽叶决明缩合单宁及相关酶活性的影响 总被引：2，自引：0，他引：2
缩合单宁对牧草品质的影响极大,适量的缩合单宁含量对于提高牧草的利用率和营养品质非常重要。研究以豆科牧草羽叶决明Cassia nictitoms为材料,分析了氮素梯度处理后茎和叶中缩合单宁的含量及其生物合成酶二氢黄酮醇还原酶(DFR)活性的变化特征。结果表明,羽叶决明叶片的缩合单宁含量高于茎,随氮素的增加,叶片中缩合单宁含量从14.78%下降到1.14%;茎中从4.62%开始降低,达到0.98%后趋于稳定;DFR活性表现出与缩合单宁相似的变化规律,二者在叶和茎中都呈显著(P0.01)的二次曲线关系。植株粗蛋白含量测定发现,随氮素的增加粗蛋白含量无显著增加(P0.05)。因此,适当增加氮素的使用量可以达到减少缩合单宁含量,从而提高羽叶决明的利用率和营养品质。 相似文献

研究了羽叶决明(Chamaecrasta nictitans)替代麸皮栽培鸡腿菇(Coprinus comatus)对其产量、绝对生物学效率、基物失重、呼吸消耗及木质纤维素转化的影响。结果表明,羽叶决明牧草替代20 %麸皮(B2)栽培鸡腿菇的产量和绝对生物学效率最高,分别为235.2 g/袋和8.86 %。覆土前和采收后的基物失重、呼吸消耗都以B6为最高,分别为13.50 %、13.50 %和35.03 %、30.71 %,其纤维素转化率也最高,为33.61 %;木质素转化率以B1为最高,达78.25 %;半纤维素转化率以B2为最高,为44.10 %。回归分析表明,羽叶决明替代麸皮栽培鸡腿菇的产量、绝对生物学效率和半纤维素转化率与替代比例呈抛物线相关,而基物失重、呼吸消耗及木质素、纤维素转化率与替代比例呈线性相关。 相似文献

A 10-year-old male neutered Boxer presented with recurrence of a mast cell tumor at the right medial canthal area. Following excision including 2 cm margins, the medial one-half of the upper and lower eyelids and the medial canthus were reconstructed using an axial pattern flap based on the cutaneous branch of the superficial temporal artery. The bulbar conjunctiva of the nictitans was preserved and sutured to the medial flap edge, thus creating a conjunctival lining to the deep aspect of the flap, protecting corneal epithelium. This is a valuable surgical technique for closing a large skin defect and reconstructing the medial eyelids, thus preserving the globe. 相似文献

Objective To evaluate a new procedure for fixation of prolapsed nictitans glands to the cartilage of the nictitans that will not interfere with the mobility of the nictitating membrane.
Methods A prospective clinical trial utilizing a nonabsorbable suture to anchor the prolapsed gland to the cartilage of the third eyelid was undertaken. Fifteen eyes of 10 dogs were included in the study. A 4-0 nylon suture was passed from the anterior surface of the third eyelid through the base of the cartilage to the posterior aspect and then tunneled circumferentially beneath the conjunctiva over and around the prolapsed gland. The suture was then passed through the cartilage again to the anterior face of the third eyelid. The gland was replaced into its normal position as the suture was slowly tightened and then tied on the anterior aspect of the nictitans.
Results Over a period of several weeks, the glands reduced in size and took on a normal appearance. All glands but one remained in place for the length of follow-up, which ranged from 2 weeks to 33 months.
Conclusions This procedure results in acceptable cosmetic effects with the return of the gland to its normal position posterior to the nictitating membrane. The advantage of this technique over traditional tacking to the orbital rim is that the third eyelid retains its normal mobility and, thus, its protective functions. The procedure once mastered is very quick and can be performed in less time than many of the traditional replacement techniques. 相似文献
