加强行业管理 促进茶叶出口 总被引：1，自引：0，他引：1
本文针对中国“入世”后，国家进一步放宽了外贸经营权，拥有茶叶出口权的企业数量增多，竞争也更加激烈，而出口配套管理机制却相对滞后，茶叶行业的无序竞争及存在的问题导致茶叶出口额的下降，提出了加强行业管理的必要性和迫切性，并探讨了主要对策。 相似文献

现代管理学之父彼得·德鲁克说过：“当今企业之间的竞争，不是产品之间的竞争，而是商业模式之间的竞争。”21世纪企业竞争的最高境界，不再是产品的竞争、人才的竞争、营销的竞争、服务的竞争……其最高境界是一种商业模式（即赢利模式）的竞争。 相似文献

由于产量与竞争力之间呈负相关，因此植株被分成了两个极端类型，即理想的高产－弱竞争型（Ｙｃ）和不受迎的低产－强竞争型（ｙＣ）．在负竞争占主导地位的密植条件下，ｙＣ型超过了Ｙｃ型，而在无竞争条件下情况正好相反．因此，要获得Ｙｃ型品种，必须在无竞争条件下进行选择．无竞争也是直接和同时选择生产力、品质和稳产性的理想条件．若能保证Ｘ和ｓ的无偏估计，那么综合指标ＣＣ＝Ｘ（Ｘ－ｓ／ｓ）则是联合选择生产力和稳产性的最有效标准。 相似文献

Two experiments were set up in a semi-controlled glasshouse environment to determine the nature of the competitive stress, and the characters associated with competitive ability, during the seedling growth of some grass species. Over a period from sowing until the attainment of a relatively stable tiller population root competition was almost entirely responsible for the suppression of Festuca arundinacea in association with H1 ryegrass at two densities. In contrast, root and shoot competition were of equal importance in bringing about the suppression of Phalaris coerulescens in association with H1 ryegrass, an effect which only occurred at the high density.
Differences in the patterns of root growth of the species and populations are discussed in relation to differences in their competitive abilities.
It is suggested that the rate and extent of nodal root production are closely associated with seedling competitive ability. 相似文献

The aim of this research is to study the feasibility of removing nitrates from water by means of anion exchange. In the purposed work an attempt was made to utilize strong basic anion resin to remove nitrate in the presence of competitive anion. Amberjet Cl- 4200 ion exchange resin was used in a batch scale. The fixation rate of nitrate without the presences of any competitive anion was almost constant (94.60-96.43) when the nitrate concentrations are in the range of 100-150 mg L(-1). The fixation rate of nitrate in the presences of two competitive anions (sulphate and chloride) was reduced to 82% when the concentration of nitrate was 100 mg L(-1). 相似文献

The aim of this study was to evaluate the effects of iron deficiency on intelligence of 11-17 years students. This study conducted on the 540 students (11-17 years) that educated at guidance and high school of Boroujerd city. Laboratory investigations were included serum iron, TIBC (total iron binding capacity) and ferretin. Riven matrix was used in order to determine intelligence quotient. Data were analyzed using SPSS 13 and chi2 and t-tests. Results showed that 78 (14.4%) students had iron deficiency and 14 (25.9%) had iron deficiency anemia. There was no significant difference between different sexes for iron deficiency distribution (p > 0.05), while iron deficiency anemia was significantly higher in girls as compared with boys (p > 0.05). Mean quotient was 115 +/- 12.1 in iron deficiency students, while it was 113.7 +/- 13.9 in patients without iron deficiency. There was also no significant difference between normal and iron deficient students for intelligence quotient (p > 0.05). 相似文献

Perennial ryegrass and white clover were grown in boxes with either no competition, root competition only, shoot competition only, or both root and shoot competition between them, Boxes received either no nitrogen or 200 kg N ha−1 as a split application. The experiment was harvested at 8, 12, 16 and 20 weeks after sowing. Perennial ryegrass was more competitive than white clover throughout the experiment and its overall competitive ability increased with Lime. The effects of root competition were greater than those of shoot competition at the first harvest, with both forms of competition having similar affects at the second harvest, while at the third and final harvests shoot competition had greater effects than root competition. At the later harvests N application increased the overall competitive ability of perennial ryegrass, relative to white clover, mainly owing to the increase in its shoot competitive ability. 相似文献

Two pot experiments were carried out in a semi-controlled environment to examine the response of individual plants to competitive stress in simple systems incorporating varying cutting frequencies and soil–nitrogen levels. A third experiment was set up outdoors to examine the effect of competition on individuals in an association, on the association as a whole, and to extend the controlled environment studies to a more complex model involving micro-plots.
Phalaris coerulescens , although its seedlings possessed a high competitive ability, showed a dramatic decline in competitive ability in later stages of the association, this decline being associated with extensive floral development. In micro–plots the effect of competition was so severe as to prevent the expression of seasonal growth characteristics by P. coerulescens .
Considerable inter-specific differences existed in the response to competition of leaf-area production per tiller during periods of regrowth.
Whilst P. coerulescens remained highly productive and maintained a dense tiller population in monocultures, its tiller regeneration following flowering was severely suppressed in competition with vegetative plants of HI ryegrass or Festuca arundinacea .
The number of heads produced per plant, head length and time of head emergence were all affected by competitive stress, the former response being a reflection of the relative competitive abilities at the time of floral initiation. The response of the latter two characters reflected the decline in competitive ability which occurred during later stages of the growth and development of P. coerulescens . 相似文献
