为探讨接种微生物对枸杞枝条基质化发酵品质的影响,采用随机区组设计,以干燥鸡粪和尿素为氮源,进行了接种外源微生物对枸杞枝条基质化发酵性能参数的影响试验.结果表明:接种粗纤维复合益菌、锯末专用复合菌和纤维素类复合酶堆体升温速度快,高温持续时间较长(高于55℃,分别达到9、5和5 d);至发酵80 d时,堆体总有机碳分别下降了8.46%、7.43%、8.06%,C/N值分别降低7.48、6.99、6.23,全氮分别为17.1、17.2、16.2 g·kg-1,全磷分别为5.1、5.2、5.0 g·kg-1,全钾分别为16.5、16.3、16.4 g·kg-1,均显著高于其他处理,且3种菌剂间无显著差异,容重分别增加了1.10%、0.91%、1.20%,总孔隙度分别增加了9.78%、10.45%、10.51%,持水孔隙度分别增加了6.21%、5.36%、8.80%,瓜菜种子发芽指数(GI)均高于85%,腐熟后的各项理化指标基本达到栽培基质的要求.综合基质的发酵温度、腐熟周期和基质保护作物根系生长及固定植株的功能对基质各项理化性质的要求,接种粗纤维复合益菌、锯末专用复合菌和纤维素类复合酶更适合枸杞枝条基质化处理. In order to explore the effects of inoculated microorganisms on the quality of the wolfberry branches, the randomized block design was used to test the effects of foreign microorganisms on the fermentation parameters of the wolfberry branches, using dry manure and urea as nitrogen sources. : Inoculation of crude fiber composite probiotics, sawdust complex bacteria and cellulose composite enzyme reactor heating speed, high temperature duration longer (higher than 55 ℃, respectively, 9,5 and 5 d); to 80 d fermentation , Total organic carbon of the pile decreased by 8.46%, 7.43%, 8.06%, C / N value decreased by 7.48,6.99,6.23, total nitrogen were 17.1,17.2,16.2 g · kg-1, total phosphorus were 5.1 , 5.2 and 5.0 g · kg-1, and the total potassium were 16.5, 16.3 and 16.4 g · kg-1, respectively, which were significantly higher than those of other treatments. There was no significant difference among the three inoculants and the bulk density increased by 1.10% and 0.91 % And 1.20%, respectively. The total porosity increased by 9.78%, 10.45% and 10.51%, and the water holding porosity increased by 6.21%, 5.36% and 8.80%, and the seed germination index (GI) After the maturity of the physical and chemical indicators to achieve the basic requirements of the cultivation of the substrate.Comprehensive substrate fermentation temperature, maturity cycle and substrate protection crop roots Function of the plant growth substrate and the fixed nature of the physical and chemical requirements, crude fiber composite inoculated bacteria, fungi and sawdust specific cellulosic composite enzyme more suitable for processing substrates wolfberry shoots.

摘要:对于高中英语这样一个需要对大量信息进行综合处理的学科而言,教师应注重学生信息处理能力的培养。笔者根据多年高中英语教学经验,在文中就如何在高中英语教学中培养学生整合英语信息的能力问题进行了浅要探讨。  关键词:高中英语教学;信息整合能力;应用策略  中图分类号:G427文献标识码:A 文章编号:1992-7711(2013)15-044-1引言  普通高中英语课程标准提出,根据高中生的学习认知
一、活动背景与理念    自信是一种信念。它是成功的必要条件,同时也是成功的源泉,所以从小培养小学生的自信心就显得尤为重要。新学期刚一接手这帮孩子,我就发现他们不管做什么事情都不积极:上课没有人愿意主动回答问题、竞选班干部时没有人愿意参加……面对这样的情景,我静静反思后,渐渐地我找到了问题的所在——他们缺乏自信,所以培养孩子自信已经成为我工作的首要任务。  本设计旨在以“活动”、“体验”为主,指导
