1Soil boron fertilization:The role of nutrient sources and rootstocks in citrus production显示文摘Boron(B) is a key element for citrus production, especially in tropical regions, where the nutrient availability is commonly low in the soil. In addition, information about doses, fertilizer sources, methods of application, and particularly, differential nutrient demand of scion/rootstock combinations are required for efficient fertilization of commercial groves. In a non-irrigated sweet orange orchard(cv. Natal), grafted onto Rangpur lime, Swingle citrumelo or Sunki mandarin, we studied the application of two sources of B: boric acid(17% B, soluble in water) and ulexite(12% B, partially soluble in water) at four levels of supply(control without B, and soil application of 2, 4 and 6 kg ha^(-1) yr^(-1) of B). The experiment was carried out for three years(2004-2006). Boron availability in the soil and concentration in the leaves, as well as the fruit yield and quality of trees were evaluated. Soil B extracted with hot water and total leaf B positively correlated with doses of the nutrient applied to the trees. Levels of B in the soil and in the leaves did not vary with fertilizer sources. Fruit yield of trees grafted onto Rangpur lime and Swingle citrumelo was more responsive to B doses than those grafted onto Sunki mandarin. The maximum fruit yield of trees grafted onto Swingle was obtained with 3.2 kg ha^(-1) yr^(-1) of B, and leaf B level of 280 mg kg^(-1) that point out to a highest demand for B when this combination was compared with other rootstocks. Furthermore, fertilization with B did not affect the quality of fruits, but correlated with B and potassium(K) concentrations in the leaves. These results also support that the current recommendations for levels of B in leaves should be revisited.Dirceu Mattos Jr Franz W R Hippler Rodrigo M Boaretto Eduardo S Stuchi Jose A Quaggio 2017Journal of Integrative Agriculture2017,16,7:5
2Optimization of the transmitted wavefront for the infrared adaptive optics system显示文摘The adaptive optics system for the second-generation Very Large Telescope-interferometer(VLTI)instrument GRAVITY consists of a novel cryogenic near-infrared wavefront sensor to be installed at each of the four unit telescopes of the Very Large Telescope(VLT).Feeding the GRAVITY wavefront sensor with light in the 1.4–2.4μm band,while suppressing laser light originating from the GRAVITY metrology system requires custom-built optical componets.In this paper,we present the development of a quantitative near-infraredpoint diffraction interferometric characterization technique,which allows measuring the transmitted wavefront error of the silicon entrance windows of the wavefront sensor cryostat.The technique can be readily applied to quantitative phase measurements in the near-infrared regime.Moreover,by employing a slightly off-axis optical setup,the proposed method can optimize the required spatial resolution and enable real time measurement capabilities.The feasibility of the proposed setup is demonstrated,followed by a theoretical analysis and experimental results.Our experimental results show that the phase error repeatability in the nanometer regime can be achieved.YANG PengQian HIPPLER Stefan ZHU JianQiang 2014Science China(Physics,Mechanics & Astronomy)2014,57,4:4
3基于自参考的高精度红外点衍射干涉仪研制(英文)显示文摘介绍了一种结构简单紧凑、可用于高精度实时相位波前测量的红外点衍射干涉仪,采用类迈克耳孙的光学结构,并结合低通小孔滤波,同时使用窗口傅里叶变换的方法解调单幅离轴载波条纹。与传统波前测量技术相比,所提出的准共光路的光学系统结构有效地抑制了系统像差及外部环境干扰等对测量结果的影响,实现高精度和高分辨率的波前探测。实验结果表明,该方法能够实现高精度的相位测量,且其重复精度达到了纳米量级。杨朋千 Stefan Hippler Casey Deen Wolfgang Brandner Sarah Kendrew 缪洁 张艳丽 朱健强(指导) 2013中国激光2013,40,5:3
