毕节市漆树品种产量与树皮性状的灰色关联度分析     

刘崇欣  周应书  毕宁 《贵州农业科学》2015,(5)

为漆树优良品种的选择以及灰色系统理论在林业林木品种评价上的运用提供参考，对毕节市8个漆树品种红漆大木、粉皮大木、灯台大木、红尖大木、肤胭皮、粉红皮、白杨皮、青杠皮等树皮解剖中6个主要性状与产漆量的关系进行灰色关联度分析。结果表明：漆树树皮解剖的单个性状对产漆量有直接影响，其中以漆汁道直径的大小关系最重要，直接关联度达0．7964；其次是活皮漆汁道单位面积与活皮厚度。从树皮解剖的综合性状看，漆树品种最好的依次是红尖大木＞红漆大木＞肤胭皮＞灯台大木＞白杨皮＞粉皮大木＞粉红皮＞青杠皮。分析结果与实际生产基本一致，表明在林业生产中运用灰色关联分析进行综合评价是可行的。  相似文献   

蛋鸡场清粪技术效能的层次分析法评价     

毕璐璐  廖新俤  吴银宝  王燕 《中国家禽》2014,36(21)

蛋鸡场采用的清粪技术包括人工清粪、刮粪板清粪、传送带清粪等.本文通过现场调研不同地区不同规模的蛋鸡养殖场清粪技术,构建了层次分析法模型,从技术成熟度、技术应用效果、技术经济评价等方面对蛋鸡场清粪技术进行了效能评价.结果表明,蛋鸡场采用人工清粪、刮粪板清粪和传送带清粪技术效能得分分别为77.72、85.83和87.36,传送带清粪和刮粪板清粪技术的效能得分均显著高于人工清粪技术(P＜0.05),传送带清粪技术效能与刮粪板清粪技术间无显著差异(P＞0.05);随着蛋鸡存栏数的增加,传送带清粪技术的效能值增加,但不同规模未显著影响传送带清粪技术效能(P＞0.05);年存栏20万～50万只商品蛋鸡的蛋鸡场,采用刮粪板清粪、传送带清粪和人工清粪技术时效能值分别为85.83、84.00和77.72,3种清粪技术间差异不显著(P＞0.05).本研究可为不同规模和不同区域的蛋鸡场选用清粪技术时提供参考.  相似文献   

Pathogen Analysis of Goat's Respiratory Diseases     

TAO Li  LAN Xian-li  LI Jun  MA Chun-xia  LAN Jin-hong  HUANG Ming-xue  LAN Mei-yi  BI Bing-fen  CHEN Ze-xiang  YANG Wei 《中国畜牧兽医》2016,43(4):1072-1078

To investigate the pathogens of goat's respiratory disease from a goat farm in Guangxi province, the epidemiological investigation, clinic observation, pathological examination, bacterium isolation and identification, biochemical test, PCR and animal experiment test were conducted.The preventive and control measures were taken on the basis of pathogen epidemiological characteristics and drug sensitive test results.The results showed that Mycoplasma, influenza virus and parasite were negative by isolation and culture or PCR, however, two strains of gram-negative bacteria named MS1 and MS2 were isolated from lung.MS1 was identified as Serratia marcescens by biochemical test and 16S rRNA sequencing, which shared 99% nucleotide homology with other Serratia marcescens in GenBank.And MS2 was identified as E.coil by the same methods that shared 99% nucleotide homology with other E.coli in GenBank.Animal experiment showed that two strains could cause death in mice.The drug sensitive tests showed two strains were highly sensitive to spectinomycin, amikacin, kanamicin and neomycin.Kanamycin and dexamethasone were used to treat the sick goats, and achieved good results.  相似文献   

玉米胚芽综合利用研究进展     

毕韬韬  吴广辉 《农产品加工．学刊》2014,(15):72-73

我国是世界上第二大玉米生产国,播种面积和总产量均占世界玉米播种面积和总产量的15%以上。玉米胚芽是酒精工业、玉米淀粉工业的副产物,其主要成分是脂肪和蛋白质,脂肪含量高达55%左右,蛋白质和灰分含量次于脂肪,因此对玉米胚芽进行综合利用意义重大。  相似文献   

Infections Investigation of ALV and REV in Guangxi Local Poultry Breeds and Sequence Analysis of gp85 Gene of ALV Isolates     

ZHONG Xing-fu  WANG Pei-kun  YANG Yong-li  QIN Li-li  BI Yu-yu  ZOU Guang-zhen  PENG Hao  WEI Ping 《中国畜牧兽医》2015,42(7):1647-1653

In order to investigate the infection status of avian leukosis virus (ALV) and avian reticuloendotheliosis virus (REV) in the major local breeds of Qinzhou,Guangxi,totally 953 samples of egg white,cloaca swab and serum of Ma duck,Shitou goose,Tiejiao-Ma chicken,turkey and pigeon were collected from the representing flocks and detected by the commercial ELISA kits.ALV was isolated for the ALV p27 positive samples by culturing on DF-1 cells,and gp85 gene was sequenced.The results showed that the detections of ALV were negative in the samples except those of Tiejiao-Ma chicken,while REV antibody was found positive in Ma duck,Tiejiao-Ma chicken and turkey.The nucleotide sequences of gp85 gene of two isolates shared 94.5% identity with each other,and shared 86.9% to 94.9% with reference strains.The amino acid sequences of gp85 gene of two isolates shared 91.5% identity with each other,and shared 84.0% to 91.6% with reference strains.There were many variable sites in the hyper variable region hr1 and hr2,and the vr2 and vr3 variable regions were relatively conservative.Phylogenetic tree analysis showed that the two isolates shared the highest homology with SCAU11-XG strain.  相似文献

葡萄山椒落花落果规律及提高坐果率研究     

赵京献  毕君 《北方园艺》2012,(22)

以5～7 a生葡萄山椒为试材,研究了葡萄山椒落花落果的规律;并针对上述原因,开展了不同雌雄株配置比例20:1、10:1、4:1处理、喷布不同植物生长调节剂等方法对提高葡萄山椒坐果率的影响试验.结果表明,葡萄山椒落花落果的主要原因是授粉受精不良、生理失调、营养不足及环境不良等.不同雌雄株配置比例表明:雌雄株比例为4:1时葡萄山椒坐果率最高;喷布赤霉素、枣丰灵和硼砂等可明显提高葡萄山椒的坐果率,喷布清水对提高葡萄山椒坐果率也有一定效果,2,4-D溶液对提高葡萄山椒坐果率效果不明显,其中以花期喷施50 mg/L赤霉素效果最好.  相似文献
