不同施肥方式对款冬生长情况和产量的影响

Effects of Different Fertilization Methods on Growth and Yield of Tussilago farfara L.

为研究施用氮、磷肥对款冬生长情况和产量的影响,采用随机区组试验设计开展试验,定期测定款冬生长指标并统计产量。结果表明,在和政县高寒阴湿地区,基肥施60%+60 d后施肥20%+孕蕾期施肥20%处理款冬株高、叶片数、株幅生长表现佳,基肥施60%+60 d后施40%处理款冬产量表现佳,且款冬在生长过程中对磷肥的利用好于对氮肥的利用。说明采用基肥施60%+60 d后施40%的施肥方式有利于增加款冬产量。

In order to study the effects of applying nitrogen and phosphorus fertilizer on the growth and yield of Tussilago farfara L., a randomized block design was used to carry out the experiment, and the growth indicators of Tussilago farfara L. were measured regularly and the yield was calculated. The results showed that in the cold and humid area of Hezheng County, the plant height, leaf number and plant width of Tussilago farfara L. treated with 60% basal fertilizer+20% topdressing after 60 days+20% fertilization at bud pregnancy stage had a good growth performance, and the yield of Tussilago farfara L. treated with 60% basal fertilizer+40% topdressing after 60 days had a good performance, and the utilization of phosphorus fertilizer was better than that of nitrogen fertilizer in the growth process of Tussilago farfara L. It showed that 60% basal fertilizer+40% topdressing after 60 days was beneficial to increasing the yield of Tussilago farfara L.
