摘要: <正>研究了不同成分配比的根际微生态保健剂在拌土和蘸根两种施用方式下,对河北杨造林成活率、树高、胸径、树皮相对膨胀度、烂皮病发病率、感病指数以及树体电容的影响。结果表明,根际微生态保健剂对造林成活率、树皮相对膨胀度、树体电容、树木的高生长和胸径生长具有明显的促进作用,对林木的发病率和感病指数有明显的降低作用。同时,拌土处理下树木的各项指标显著优于蘸根处理。保健剂的4种主要成分菌剂、植物生长调节剂、复合肥以及保水剂对树木的作用特点也不同。在此基础上,确定了最佳杨树抗逆保健的各因素水平以及施用方法,优化后的抗逆保健剂成分质量配比为:菌根制剂74.997%,保水剂10.000%,复合肥14.999%,植物生长调节剂0.004%。

Abstract: The methodological condition of extracting the tea polyphenols from the bamboo leaves of Phyllostachys glauca Mcclure under microwave radition, using the ethyl hydroxide as the extracting agent was studied. The condition of the extraction in the experiment, the influent factors of the power of microwave radiation,concentration of the solvent,proportion between of the bamboo leaves and the solvent (g/mL),extracting time,stages of the extraction and times of the ethyl acetate extraction and so on were also studied. By microwave radition, the proper condition of extracting tea polyphenols from the bamboo leaves could be obtained. According to the GB/T 8313--2002, the UV-9200 spectrophotometric instrument was used to analyze the absorbancy of the tea polyphenols and the content of the tea polyphenols was analyzed. By the experiment, the proper condition of extracting tea polyphenols from the bamboo leaves under microwave radition was got 1.43% (mass percent) tea polyphenols was prepared with the 0. 125 g/mL proportion between of the leaves of the Phyllostachys glauca and the solvent,60% concentration of the ethyl hydroxide under the 320 W microwave radiation for 4 rain.
