彭清华  彭俊  谭涵宇  戴宗顺  陈柯竹 《勤云标准版测试》2015,35(10):1-5

目诊是通过观察眼睛各部位的神、色、形、态变化来诊断疾病的一种方法,是中医学的重要组成部分,中医目诊的理论依据是目为五脏六腑的缩影,目与脏腑经络密切相关;眼分五轮八廓,分属于脏腑;及现代生物全息理论的进一步支撑。中医目诊研究的主要方法包括传统中医的望、问、切诊和在此基础上发展的分区望诊法、虹膜诊断法、及眼底图像分析法等借助现代诊断设备的方法。  相似文献   

基于产量响应诊断冬小麦水分亏缺适宜土层及其水分阈值   总被引：4，自引：3，他引：1

明确作物产量对水分亏缺的响应是实施非充分灌溉的科学基础。该文在华北气候下,通过设置不同灌水次数造成处理间的土壤供水差异,探讨了大田冬小麦籽粒产量与不同生育时期、不同土层深度的土壤水分之间的关系,系统分析了影响小麦产量的水分阈值,提出了适宜的土壤水分诊断深度。结果表明:不论从土壤水分动态、还是从全生育期平均水分来看,亏水处理与充分供水对照在浅层土壤的水分差异最大,且随土层深度增加而减小。0~0.4、0~0.8、0~1.2 m的水分差异分别在19.7%~36.5%、9.3%~21.7%和2.9%~9.7%之间。此外,土壤水分变异程度随土层深度增加而减小。不同生育期、不同深度的水分与小麦产量关系多为开口向下的抛物线函数,但函数关系的显著程度随生育期及土层深度而变化,其中0~0.4 m的水分与产量关系最为密切。影响小麦产量的水分阈值随生育进程呈下降趋势。自拔节孕穗至乳熟期,0~0.4、0~0.6、0~1.0、0~1.2及0~1.6 m的水分阈值由田间持水率的83.1%~95%下降到72.3%~90.0%。依据处理间土壤水分动态差异、全生育期平均水分差异、不同土层的水分变异程度、土壤水分与小麦产量关系显著性程度4方面的分析,该文提出0~0.4 m为适宜的水分亏缺诊断深度,相应在拔节孕穗、抽穗、开花、灌浆初期、灌浆中期、灌浆后期、乳熟期的水分阈值分别为95.0%、98.4%、79.9%、73.7%、88.6%、79.6%和75.7%。该结果对小麦亏缺灌溉管理具有实际指导意义。  相似文献

Digit innervation of the thoracic limb of Criollo horses: Anatomical description and consequences to perineural blocks     

Bruno Belmonte Silveira  Erick Candiota Souza  Matheus Damasceno Nunes dos Santos  Marcelo Lameiro Porciuncula  Marcos da Silva Azevedo  Claudia Acosta Duarte  Amarílis Díaz de Carvalho  Paulo de Souza Junior 《Anatomia, histologia, embryologia》2020,49(6):728-736

Criollo horse breeding is an important economic activity in South America. Because of their athletic performance, these animals tend to show great incidence of musculoskeletal disorders, many of them diagnosed by means of perineural blocks. However, incorrect interpretation of these blocks may be due to anatomical differences in nerve distribution. The objective of this study was to describe the innervation of the digit region of thoracic limbs in Criollo horses, in order to improve the interpretation of tests for claudication diagnosis based on nerve block. Thirty thoracic limbs from Criollo horses were dissected. It could be observed that in 90% of the limbs, dorsal branches of the palmar nerve originated proximally to the proximal sesamoid bone. In 93% of the cases, the palmar digital nerve and the dorsal branches communicated; in 87% of the cases, communication between branches of the dorsal branch was observed; and in 27% (8/30) of the limbs, the palmar metacarpal nerve and the dorsal branch presented communications. None of the specimens showed complete symmetry in the distribution of nerves in contralateral limbs. The high frequency of communication between the nerves may be a particularity of the Criollo breed that may interfere with the interpretation of perineural blocks. Based on the anatomical position, it may be inferred that divergent results in Criollo horses may occur when abaxial sesamoid nerve block is used. Palmar digital nerve block may be less influenced by these variations, provided it is performed as distal as possible from the ungular cartilage.  相似文献

红壤性水稻土的分类及其鉴定指标     

吴金奖  邢世和  林景亮 《福建农林大学学报(自然科学版)》1990,(1)

提出以水型和起源土壤类型作为亚类的划分依据。土属必须考虑母质因素的影响。红壤性水稻土亚类的划分除了考虑指示性土层特性外,还必须考虑土体构型、物质淋淀以及土壤属性的剖面变化趋势。本文初步提出划分红壤性水稻土亚类的一系列指标。  相似文献   

Production and Spad Reading in Marandu Palisadegrass Fertilized with Nitrogen and Magnesium     

T. B. Garcez  M. M. Megda  A. G. Artur  F. A. Monteiro 《Journal of plant nutrition》2014,37(9):1475-1486

The increase in tropic grass production and its estimation by the SPAD value can be related to combined supply of nitrogen and magnesium. The objectives were to check the effect of magnesium (Mg) rates on the productive response of Marandu palisadegrass to nitrogen (N) rates; correlate the supply of N and Mg with the SPAD reading; establish the use of SPAD reading as a way of predicting the N and Mg concentrations in diagnostic leaves (DL) and shoot dry matter (SDM). The experiment was carried out in a greenhouse. Five N rates and five Mg rates were used in nutrient solutions, in a fractionated 5 × 5 factorial design with four replications. High N and Mg rates resulted in high dry mass yield and leaf area, in greater numbers of leaves and tillers. The correlations between SPAD reading and SDM, N and Mg in DL were high, high and low, respectively.  相似文献
