郭佳康 《现代农业科技》2019,(13)

以藏羊肉和蕨麻为主要原料进行新型复合型蕨麻佐餐藏羊肉酱的制作,在单因素试验基础上采用感官品评和正交试验分析,对复合酱配比、植物油添加量、藏羊肉添加量、蕨麻添加量以及复合酱添加量5个因素进行正交试验,依据感官评分表进行感官品评,确定蕨麻佐餐藏羊肉酱加工的最佳配方。结果表明,对蕨麻佐餐藏羊肉酱品质影响的因素依次为复合酱配比>复合酱添加量>植物油添加量>蕨麻添加量>藏羊肉添加量;并确定最终配方为植物油20.7%、羊肉17.2%、蕨麻3.4%、辣椒酱13.8%、甜面酱5.2%、花生酱5.2%、牛肉精膏0.3%、葱沫8.6%、蒜沫8.6%、盐1.0%、鸡精2.0%、味精1.7%、白糖3.1%、生姜粉0.3%、海天酱油3.1%、白芝麻1%、瓜子仁1%、辣椒粉3.4%。  相似文献   

The effects of density and artificial substrate on intensive shrimp Litopenaeus vannamei nursery production     

《Aquacultural Engineering》2020

Recirculating aquaculture systems (RAS) can be installed indoors, allowing year-round production of tropical animals in nearly any climate. A nursery phase is commonly used in Litopenaeus vannamei production since it allows for enhanced biosecurity and better quantification of animals while reducing space requirements. However, it is unclear whether animal density and inclusion of artificial substrate may improve shrimp performance during the nursery phase. In this experiment, we compared shrimp production parameters in two stocking densities with or without the use of an artificial substrate by creating four treatments: low-density LD; 1500 PL/m⁻³, low-density with substrate LDS, high-density HD; 3000 PL/m⁻³), and high-density with substrate (HDS). The LDS and HDS treatments included 0.46-m² of high-density polyethylene 2.5-cm mesh as a substrate, which increased the tank surface area by 21 %. Each treatment was randomly assigned to four 160-l culture tanks, each with a biofilter. The shrimp had an initial weight of 4 mg and were grown for 50 days. The low-density treatments had significantly higher dissolved oxygen (DO) and pH than the high-density treatments (P ≤ 0.001). Specifically, LDS had the highest DO and pH followed by the LD, HD, and HDS treatments, respectively. High-density treatments had significantly higher NO₂-N levels than low-density treatments during week 2 of the experiment when an unusually high concentration of nitrite was observed. FCR was significantly lower in both low-density treatments than in high-density treatments. At harvest, the total biomass (kg m⁻³) was significantly higher in high-density treatments than in low-density treatments (P ≤ 0.001), and the HDS treatment had a significantly greater biomass output than HD. Producers should consider artificial substrate and higher densities during nursery production to maximize shrimp production; however, the effects on water quality should also be taken into account.  相似文献

无菌条件下野蔷薇种子快速催芽的研究     

韩益  赵梁军 《勤云标准版测试》2006,(6)

野蔷薇种子休眠深,发芽极不整齐,给育苗带来很大麻烦。以野蔷薇的3个无刺品系No.3、No.4、No.11和野蔷薇变种荷花蔷薇为试材,研究在无菌条件下,冷藏时间、GA3浓度和不同基质对野蔷薇种子发芽的影响,探索快速得到无菌实生苗的条件。结果表明:(1)影响野蔷薇种子萌发最主要的因素是冷藏时间;(2)3个无刺品系种子在冷藏10～15d、GA30.05～0.1mg/L处理时发芽率均在90%～100%,而荷花蔷薇种子在冷藏15d、GA30.05mg/L处理时最高发芽率为73%;(3)选用沙子作基质比蛭石更适合种子发芽。  相似文献   

The rates of maize growth and lignin biosynthesis change after root-applied chalcone     

WEIJUN CHEN  MIN-SOO YUN  FAN DENG  YASUHIRO YOGO 《Weed Biology and Management》2005,5(3):118-122

The effects of root-applied chalcone at 0.15 mmol L⁻¹ on the growth and lignin biosynthesis in maize were investigated. The contents of 4-coumarate: CoA ligase (4CL, EC 6.2.1.12) substrates in maize shoots were increased more rapidly in the samples with chalcone application than in the control and the increase occurred at ≤ 3 h after the application (HAA). The lignin content was reduced by chalcone at ≤ 6 HAA. The shoot growth was suppressed by chalcone at ≤ 9 HAA. Consequently, the results suggest that chalcone suppressed maize growth by inhibiting monolignol biosynthesis.  相似文献

杨飞  姚金晓  张志刚  张成浩 《分子植物育种》2020,(6):1983-1990

以传统基质草炭、蛭石及腐熟羊粪和玉米秸秆为原料,配制成12种不同配比的栽培基质,以商品叶菜类栽培基质作为对照,研究不同基质配方对生菜生长的影响,以期获得最适合生菜栽培的基质配比组合。结果表明,不同组合基质配比均能满足生菜的正常生长,所有处理的株高、叶面积、单株鲜重和单株干重都较对照组(CK)有着不同程度提高,其中T11(草炭∶腐熟羊粪∶玉米秸秆∶蛭石=1∶4∶3∶4)条件下各指标表现最好,分别较CK提高了31.80%、47.15%、59.43%和79.53%;从生理生化指标来看,T11处理的Vc含量最高,是CK的2.5倍;T10(草炭∶腐熟羊粪∶玉米秸秆∶蛭石=3∶1∶4∶4)的根系活力是所有处理中最高的,达到CK的2.02倍;T12(草炭∶腐熟羊粪∶玉米秸秆∶蛭石=3∶4∶1∶4)处理的叶绿素含量最高,是CK的1.41倍,硝酸盐含量最低,较CK降幅达到74.59%。通过隶属函数进行综合比较分析,我们认为T11是所有供试处理中最适合生菜栽培的基质配比。  相似文献   

东北“三大硬阔”叶片和叶轴质量分配比较     

张海燕  陈立明 《东北林业大学学报》2016,(6)

以3个树种健康复叶为试材,研究了叶内光合构件和支撑构件的生物量投资的种内种间变化规律。结果表明:水曲柳、胡桃楸和黄檗叶轴质量占复叶质量的比例分别为0.18、0.26和0.17,胡桃楸显著大于其它2个树种。跨物种尺度上,复叶大的树种需要更多的叶内支撑结构投资。但物种水平上,水曲柳叶片投资随叶增大而增大,胡桃楸则降低,黄檗基本稳定,表现出与跨物种水平上的叶片投资随叶增大而降低的普遍规律不同。今后需要加深物种水平上叶内生物量分配的异速生长的了解。  相似文献
