专用营养剂对烟草重金属含量的开发及应用研究

通过综合研究不同配方重金属营养剂对烤烟的生长发育、生理代谢、产质量以及烤后烟叶内重金属Pb、Cd、Cu含量的影响,结果表明:重金属营养剂对烟株生长发育、经济性状的形成有副作用,表现为清水对照>4号营养剂>2号营养剂>腐殖质>3号营养剂;通过对烤后烟叶重金属含量的检测,重金属营养剂能有效地降低下部烟烟叶内重金属的含量,并能抑制烟草对Cu的吸收,表现为4号营养剂>3号营养剂>2号营养剂>清水对照>腐殖质。4号重金属营养剂的表现明显优于其他配方,对烟株产质量的影响最小,有效降低烟株内重金属的含量。

直播稻专用壮秧营养剂应用技术研究

2002年直播稻在我市推广面积已达6万多亩,但大面积生产上生育前期常发生秧苗黄瘦僵苗,为此两年来我市应用壮秧营养剂进行了针对性试验.

为促进机插水稻的生产和发展,笔者对水稻专用壮秧营养剂的应用效果及其合理施用量进行了比较试验,结果表明,使用壮秧剂后,秧苗素质确实有了较大的提升,为机插水稻稳产高产奠定了基础,且不会产生任何肥害。壮秧剂最适用量为每667m2施40g。

Effects of Tobacco-dedicated Plant Nutrition Regulators on Yield and Quality of Flue-cured Tobacco Leaves

During 2012-2014,field trials were carried out in Huili County,Dechang County and Mianning County of Liangshan Yi Autonomous Prefecture to investigate effects of tobacco-dedicated plant nutrition regulators on yield and quality of fluecured tobacco leaves,aiming at providing reference for tobacco production.According to the results,in tobacco fields applied with tobacco-dedicated plant nutrition regulators,growth period of tobacco was shortened compared with control group;botanical characters（plant height,stem girth,the maximum leaf length,the maximum leaf width,internode length and leaf number） were superior to control group;after application of tobacco-dedicated plant nutrition regulators,yield,output value and the proportion of high-grade and middle-grade leaves were significantly improved compared with control group;moreover,flue-cured tobacco leaves exhibited more coordinated chemical composition.

泌乳进饲喂母猪的效果试验

现代规模化养猪 ,怀孕母猪多采用笼养技术。笼养母猪因缺少运动 ,易引起乳房水肿 ,难产死胎增多。试验选用重胎母猪 4 0头 (试验组、对照组各 2 0头 ) ,在产前、产后饲喂泌乳进。结果表明 ,饲喂泌乳进的试验组死胎率为 2 .87% ,对照组为 11.91% ,下降 9.0 4个百分点 (P<0 .0 1) ,平均产仔时间缩短 2 .1h。
