啤酒大麦品种和施氮量选择评估

施用氮肥直接影响啤酒大麦的产量和品质。因此,对每一个啤酒大麦品种,需要制定一套相应的氮肥施用技术措施。1981～1983年在Hegne粉砂粘壤土试验田,对啤酒大麦品种"Morex"和"glenn"进行施肥量和施肥方法比较试验。氮肥施用量试验,每公... 详细信息

施用氮肥直接影响啤酒大麦的产量和品质。因此,对每一个啤酒大麦品种,需要制定一套相应的氮肥施用技术措施。1981～1983年在Hegne粉砂粘壤土试验田,对啤酒大麦品种"Morex"和"glenn"进行施肥量和施肥方法比较试验。氮肥施用量试验,每公顷分为0、56、112和168公斤四种处理,施肥方法分为条施法和撒施法两种。1983年增加供试品种"Robust"。试验期间测定幼苗植株,茎秆和籽粒的含氮量;测定茎秆和籽粒的产量以及籽粒饱满度百分率。因为土壤中硝态氮含量不同,引起了品种与年分之间交互作用,施氮量与年份之间交互作用均达到显著水平。通过方差分析表明,品种和氮肥施用量是引起啤酒大麦产量和品质波动的最主要的影响因素。氮肥施用方法之间差异不显著。三年试验结果表明,每公斤籽粒含氮量不超过21.6克,即符合制麦工艺的要求。在籽粒产量和籽粒饱满度方面,"glenn"品种优于"Morex"品种。但1983年试验结果,不同氮肥量处理,"Robust"品种表现最好,其次为"glenn"品种和"Morex"品种。每一个啤酒大麦品种,只要巧施氮肥,均可以获优质得高产。

Open Journal of Pediatrics 2015年第1期5卷 67-75页

It is very important to understand that the univentricular heart surgery is just palliative, not being in anyway a definitive or curative surgery, but nowadays it’s the best initial treatment of this complex heart disease. The fundamental philosophy of treatment of every univentricular heart is to ensure the flow system and/or restrict the lung flow. Thus, initially a patient with univentricular heart who is undergoing surgery may need to ensure systemic flow (reconstruction of the aortic?arch type Norwood), to restrict the lung flow (pulmonary banding) or to provide enough?pulmonary flow (pulmonary-systemic fistulae). However, some heart diseases with univentricular physiology remain “balanced” autonomously, until the “second” stage of palliation is performed (cavo-pulmonary anastomosis type glenn), but others require performance of pulmonary banding, if there’s no native lung protection and/or repair of the systemic circuit in a first stage, to reach next palliation steps in the best possible conditions.
