论种业企业服务营销

市场经济条件下,种业企业在以质量谋生存、以信誉求发展的今天,在买方市场上,种业营销除了产品、价格、渠道、促销这几个方面外,各大种业公司都把产品售前、售中、售后服务作为重要一环来抓,把服务作为企业再次创造利润不可或缺的一部分.由此,服务营销也就应运而生.服务被经济学家认为是第二次竞争,是至尊的事业,服务得民心,民心定天下.作为种业企业的服务营销,应从以下几个方面来着手. 售前服务重点是建立客情关系、提高品牌知名度、认知度,塑造品牌,整合品牌形象. 在市场经济条件下,必须以质量谋生存,以信誉求发展.正规化的种子经营首先以质量为基础,质量是企业的生命,是取得经济效益的前提和保证.要加强种子生产中各个环节的质量管理,强化员工生产名牌种子的意识,绝不允许不合格的种子入库,进入自己的销售网络.牢固树立"质量第一,信誉至上"的观念,生产出高质量的名牌种子.

6个栓皮栎种源种子形态及其幼苗生长的比较

[Objective]To compare the differences of seed morphological characters among provinces of Quercus variabilis Bl.,and explore the adaptive growth status of seedlings growing in the central distribution area. [Method]The seeds of 6 Q. variabilis provenances from six provinceswerecollected, and the seedlings were cultivated and transplanted to experimental field in the centre of natural distribution range (Wuhan Jiufeng National Forest Park), then the seed morphology and one-year seedling growth traitswere surveyed. [Result](1)There were significantor extremely significantdifferences among provenances in seed length, seed width, seed length/width ratio and 100-seed mass, the order of seed length among provenances was Beijing Provenance (22.28 mm),Hubei Provenance (22.10 mm), He'nan Provenance (20.80 mm), Shaanxi Provenance (19.57 mm), Yunnan Provenance (18.93 mm)and Liaoning Provenance (18.81 mm), the seed width of Beijing Provenance (19.71 mm) and Hubei Provenance (19.16 mm) was higher than that of the others, the seed length/width ratio of He'nan Provenance (1.38) was extremely significantly higher than that of the others; (2)There were significant or extremely significant differences among provenances in seedling height, ground diameter, leaf number, branching number and seedling height/ground diameter, the Beijing Provenance and Hubei Provenance were better in seedling height and leaf number, which were respectively 19.54 cm and 20.26 cm, 8.32 leaves and 9.50 leaves; (3)A decreasing trend with time for seedling growth traits among provenances was found; (4)There was a positive relationship between seed morphological characters and seedling growth traits except seed length/width ratio; the leaf number was significantly related to ground diameter and branching number and the seedling height and leaf number were closely related to the seed morphological characters; (5)It showed a decreasing trend with the growth time in the relationship between seedling growth traits and 100-seed mass. [Conclusion]The seedlings of Beijing Provenance and Hubei Provenance grew better in the experimental field which might be related to their larger seed mass, and the Yunnan Provenance in the south margin and the Liaoning Provenance in the north margin of distribution area of Q. variabilis grew weaker than the provenances in the centre of distribution area.With the effect of climate change, provenances in the margin of distribution area may lose in the community competition in the seedling stage if it cannot take advantage of its dispersal and settlement and affected by the disadvantage of growth and competition, so that the distribution and population renewal would surely be affected.
