不同施肥处理对款冬产量品质的影响

目的：研究氮、磷肥的用量对款冬产量和品质的影响。方法：采用随机区组实验设计,定期测定款冬生长指标并统计产量。结果：在和政县高寒阴湿地区氮、磷肥对款冬植株性状及花蕾产量有一定的影响,对款冬施基肥60%+60d后施肥20%+孕蕾期施肥20%的处理款冬株高、叶片、株幅生长均最佳。施基肥60%+60d后施40%处理对款冬单个花蕾数、蕾径、单个花蕾长及产量的影响最佳,款冬在生长过程中对磷肥的利用好于氮肥的利用。结论：施基肥60%+60d后施40%组合,能有效增加款冬花产量和提高款冬花的品质。

Effects of Different Fertilization Treatments on Yield and Quality of Tussilago farfara L.

Objective: To study the effect of nitrogen and phosphate fertilizer dosage on the yield and quality of Tussilago farfara L. Methods: Randomized block design was used to measure the growth index of Tussilago farfara L. and count the yield. Results: Nitrogen and phosphorus fertilizer had certain effects on plant characters and bud yield of Tussilago farfara L. in cold and humid areas of Hezheng County. The treatment of applying 60% basal fertilizer+60 days, 20% fertilizer+20% fertilizer in bud stage had the best plant height, leaf and plant width growth. Applying 60%+60 days of basal fertilizer and 40% of basal fertilizer had the best effect on the number, diameter, length and yield of single bud of Tussilago farfara L. The utilization of phosphate fertilizer was better than that of nitrogen fertilizer in the growth process of Tussilago farfara L. Conclusion: Applying base fertilizer 60%+40% after 60 days can effectively increase the yield and quality of Tussilago farfara L.
