插条粗度和萌芽度对降香黄檀扦插成活率的影响

在江门市林科所苗圃选择不同粗细度、不同萌芽度的降香黄檀插条进行扦插繁殖试验,每10 d进行1次成活率调查。结果表明:插条的萌芽度和粗细度均极显著影响扦插的成活率,萌芽度和粗细度的交互作用对扦插的成活率也有极显著影响;未萌芽插条扦插成活率明极显高于已萌芽插条的扦插成活率;3种粗细度的枝条中以粗细度为0.7~1.2 cm的插条扦插成活率最高;在枝条萌芽度及粗细度交互作用下,粗细度为0.7~1.2 cm的未萌芽插条扦插成活率最高,粗细度小于0.7 cm的已萌芽插条扦插成活率最低。

Four years validation of decision support optimising herbicide dose in cereals under Spanish conditions

The Danish decision support system Crop Protection Online (CPO) optimises herbicide weed control. CPO recommends specific herbicide solutions to achieve a required level of control. The aim is to apply herbicides as little as possible but as much as necessary. CPOWeeds is a version of CPO adjusted to conditions in North-eastern Spain. The predicted efficacies and the yield obtained with CPOWeeds were validated in winter cereal field trials from 2010 to 2013. All CPOWeeds treatments were related to the efficacies obtained with standard herbicide treatments decided upon by local advisors. The predictions from CPOWeeds were compared to the actually achieved efficacies in the field trials for the nine weed species at different developmental stages and for 84.2% of the comparisons the obtained efficacies were equal to or higher than predicted. The average difference between predicted and observed efficacies was 2.35 percentage points. Yield was measured in three trials and the recommendations from CPOWeeds were maintaining yield. There were two situations where CPOWeeds were performing suboptimal. One is in the early weed growth stages, as the model is not yet prepared to account for water stress on root action herbicides applied at 10-11 BBCH. The second situation was in fields with a prior unidentified population of resistant Alopecurus myosuroides. For key species in winter cereals in Spain, such as Avena sterilis, Lolium rigidum and Papaver rhoeas, CPOWeeds achieved a satisfactory control level. It was concluded that the use of CPOWeeds allowed optimisation of the herbicide application with a very high robustness. The recommendations were satisfactorily for the conditions of the Northeast of Spain and have the potential to decrease the amount of applied herbicides by at least 30%. Therefore, it can be an important tool in Integrated Weed Management.     

不同用量松土促根剂对冬小麦产量的影响

茶和天下语境下历史典故的重温与传播——以“以茶代酒”为例

中华茶文化历史源远流长,文化内容博大精深,是中国文化乃至世界文化重要的组成部分。然而,历史茶文化尤其是历史典故,大多需要重新解读,只有将历史与现实结合起来,有针对性且有说服力地赋予新的时代内涵,才能扩大其在世界范围的价值认同。基于此,本文以“以茶代酒”为例,将其置于茶和天下的语境下,在重温这一历史典故的基础上,从增加中华茶文化魅力,促进历史茶文化的传播的角度出发,分析探讨了以茶代酒的当代价值或中华茶文化核心价值的当代体现,并根据全球化与茶文化传播的需要,从增强自信性、构建“同型性”、抢占先机性、设计备选性等方面,提出了如何通过以茶代酒,推动中华茶文化核心价值实现的相关策略。
