随着人民生活水平的不断提高,对芹菜的质量要求越来越高,为满足生产需要,减少种子进口,必须加大良繁力度,提高西芹种子质量,降低种子生产成本。文章从以下几点作了总结:1)抓住影响种子质量的要害,提高管理水平,确保种子质量。因为品种混杂、退化、劣变是种子质量下降的根本原因,因此在制种时一定要保证繁种操作技术规程,防止生物学混杂、机械混杂等。2)努力降低种子生产成本,提高西芹种子高产、稳产。适时播种、合理育苗、适量的播种量以及生长期的分苗密度、定植密度、水肥管理等都对西芹种子的高产、稳定起着至关重要的作用。
With the continuous improvement of people’s living standards, celery quality requirements are getting higher and higher, in order to meet the production needs, reduce seed imports, we must increase efforts to improve the quality of celery seeds and reduce the cost of seed production. The article summarizes from the following points: 1) Seize the key to affecting the quality of the seeds, improve the management level and ensure the quality of the seeds. Because of the variety of hybrid, degradation, deterioration is the root cause of the decline in seed quality, seed production must ensure that the operation of technical regulations, to prevent biological hybrid, mechanical hybrid and so on. 2) Efforts to reduce the cost of seed production, increase the yield of celery seeds, stable production. Timely sowing, reasonable nursery, the appropriate amount of seeding and growing seedling density, planting density, water and fertilizer management are all on the celery seed production and stability plays a crucial role.
