加快县域经济发展,不仅是解决"三农"问题,实现十六大提出的全面建设小康社会目标的重要举措,而且是落实科学发展观,构建和谐社会的重要举措。目前,漳州县域经济还处于比较滞后的状态,经济总量较小、经济发展不平衡、财政困难等问题是制约县域经济发展的主要因素。发展壮大县域经济已是一个刻不容缓的任务,要合理确定县级政府职能,积极发展外向型经济,提高私营企业竞争力,有效推进漳州市县域经济科学、协调、快速的发展。 相似文献

要树立苗木市场的科学发展观 总被引：1，自引：0，他引：1
近年来,苗木市场风云莫测,颇有点“丈二金则摸不着头脑”的感觉。看起来搞苗木市场是门大学问,它牵涉到社会科学、自然科学和科学试验的方方面面,不单纯是做苗木生意而已。 怎样用科学发展观来指导苗木市场,坚持以人为本,树立全面、协调、可持续的发展观,有值得深入探讨的必要。以下是笔者对此问题的一管之见,供参考。 相似文献

党的十六届三中全会《决定》在论述“我国经济体制改革面临的形式和任务”时，首次提出了“科学发展观”：按照五个统筹——统筹城乡发展、统筹区域发展、统筹经济社会发展、统筹人与自然和谐发展、统筹国内发展和对外开放的要求，坚持以人为本，全面、协调、可持续的发展观，促进经济社会与人的全面发展。从此，“科学发展观”成为继“邓小平理论”、“三个代表”重要思想之后又一指导我们当前及今后改革和发展的重要理论。 相似文献

“三农”问题错综复杂,已经对中国全面建设小康社会和实现现代化形成“瓶颈”性制约。但其无论如何复杂,怎么变换,都离不开农民利益这个核心问题。关键是要坚持以人为本的科学发展观和统筹城乡发展的指导思想,充分认识农民利益的重要意义,树立综合全面的、整体协调的、区别对待的、脚踏实地的、可持续发展的、客观公正的、有制度保障的农民利益观,才能够实现好、维护好、发展好农民利益,从而推动“三农”问题的根本解决。 相似文献

Shrivel is a potential storage quality problem for kiwifruit. ‘Zesy003’ (commonly called Gold9) is a newly released, yellow-fleshed Actinidia chinensis cultivar that tends to shrivel more than other commercialised cultivars. Water loss and shrivel in Gold9 fruit were investigated during storage at 1 °C for up to 14 weeks and shelf-life at 20 °C. In addition, the water status of ripe fruit was quantified by magnetic resonance imaging and the capacity of a crude outer pericarp cell wall extract to swell. Shrivelled Gold9 fruit had 1–6% weight loss, although 6% weight loss did not always result in shrivel. Three weeks of storage resulted in fruit taking longer to shrivel during shelf-life, with a concomitant higher weight loss by the time the fruit was shrivelled. In contrast, 14 weeks of storage resulted in fruit that shrivelled more rapidly in shelf-life at a lower weight loss. At any given time after harvest, fruit with more severe shrivel tended to be softer than less shrivelled fruit. Shrivel therefore appears associated with fruit softening. Outer pericarp tissue from ripe Gold9 fruit had lower water mobility and a greater capacity to swell than pericarp from other kiwifruit cultivars. It is concluded that shrivel is not determined simply by an absolute amount of water loss. The development and ease of expression of shrivel in Gold9, and possibly other kiwifruit, is influenced by softening and the water characteristics of the fruit outer pericarp when soft. 相似文献

鞍带石斑鱼胚胎发育及仔鱼形态发育、饵料转变的观察研究 总被引：2，自引：0，他引：2
本文对鞍带石斑鱼（Epinephelus lanceolatus）的胚胎发育、仔鱼形态发育及饵料转变进行了观察研究,详细描述了胚胎发育各个时期的形态特征。鞍带石斑鱼受精卵在水温29±0.5 ℃、静水微充气、盐度30的孵化条件下,经过18 h 30 min仔鱼开始孵化出膜。胚胎发育过程分为卵裂期、囊胚期、原肠胚期、神经胚期和器官形成期。在水温25.0~30.0 ℃和盐度33.0 ~35.0的室外水泥池进行初孵仔鱼的培育试验,仔鱼在孵化出膜后72h开口摄食。4日龄仔鱼的卵黄囊几乎完全消失,开始摄食原生动物;从5日龄开始,摄食行为明显,摄食原生动物和小轮虫; 8日龄仔鱼逐渐转向摄食桡足类,兼食少量的轮虫;13日龄后,仔鱼的饵料以桡足类成体为主,摄食量大;经过21天培育进入稚鱼期。 相似文献

Summary Of 191 interspecific crosses attempted between 27 different species representing different subgenera ofLilium only 14 gave rise to seeds and only 6 of these were viable. Sterility was associated with various types of abnormality in endosperm development. Many of these irregularities involved chromosome breakage and reunion but others entailed abnormal DNA replication and chromosome coiling. In one cross the individual endosperm nuclei contained four stranded structures, the behaviour of which at division was similar to that of bivalents at meiosis. The embryo-sac ofLilium is of theFritillaria type, containing both haploid and triploid polar nuclei. As a consequence the balance between the number of chromosome sets in the embryo, endosperm and maternal tissue is 2:5:2 and not 2:3:2 as is more commonly found in diploid species. It is suggested that sterility results from genetic imbalance of the endosperm itself rather than interaction of the endosperm with either embryo or maternal tissue. 相似文献

Accurate modelling of plant development is the basis for any assessment of climate change impact on crop yields. Most rice models simulate development (phenology) based on temperature and photoperiod, but often the reliability of these models is reduced beyond the environment they were calibrated for. In our study, we tested the effects of relative air humidity and solar radiation on leaf appearance rate in greenhouse experiments and analysed data sets from field studies conducted in two extremely different rice-growing environments in Nepal and Senegal. We also analysed environmental effects on duration to flowering of one popular IRRI material (IR64) for eight different sites covering the entire temperature range where rice is widely cultivated. Both low relative air humidity and low solar radiation significantly decreased leaf appearance rate. Mean air temperature explained 81% of the variation in duration to flowering across sites, which was furthermore significantly influenced by relative air humidity. Across all sites, a simple linear regression approach including mean air temperature and mean relative humidity in the calculation of duration to flowering led to a root mean square error (RMSE) of 10 days, which was slightly lower than the RMSE of 11 days achieved with an automated calibration tool for parameter optimization of cardinal temperatures and photoperiod sensitivity. Parameter optimization for individual sites led to a much smaller prediction error, but also to large differences in cardinal temperatures between sites, mainly lower optimum temperatures for the cooler sites. To increase the predictive power of phenological models outside their calibration range and especially in climate change scenarios, a more mechanistic modelling approach is needed. A starting point could be including relative air humidity and radiation in the simulation procedure of crop development, and presumably, a closer link between growth and development procedures could help to increase the robustness of phenological models. 相似文献
