摘　　要：为进一步提高芫根产量和种植芫根的经济效益,选取玉树藏族自治州地方品种玉树芫根为材料,以不施肥(CK)为对照,研究不同配比的N、P、K肥料对芫根根长、根粗、鲜质量的影响,采用隶属函数法综合评价其农艺性状,并对各个施肥处理获得的经济效益进行比较。结果表明,NP10处理下根长最长,为5.53 cm,N20处理下对玉树芫根根粗和根鲜质量促进效果最好,分别为9.43 cm和299.33 g。在NP10处理下,根形指数达到0.69,接近圆形,商品性较好。综合评价结果表明,N20(每667 m^(2)追施20 kg尿素)隶属函数值最高,达到0.84,产生的经济效益为1006.39元。综上所述,每667 m^(2)施用20 kg尿素提高了玉树芫根的产量及经济效益,研究结果为后续芫根高产种植提供了合理的施肥方案。In order to further promote the yield of turnip and improve the economic benefits of planting turnip,the local variety of Yushu turnip inYushu Tibetan Autonomous Prefecture was used as plant materials,and the effects of N,P and K fertilizers of different proportions on root length,root thickness and fresh mass of Yushu turnip were studied with no fertilization(CK)as the control.The membership function was used to comprehensively evaluate the agronomic traits,and the economic benefits from each fertilization treatment were compared.The results showed that the root length was longest under NP10 treatment with length of 5.53 cm.The best effect of promoting root transverse diameter and fresh mass was under N20 treatment,which were 9.43 cm and 299.33 g,respectively.The root shape index reached 0.69 under NP10 treatment and the root shape was nearly circular with good commodity.The comprehensive evaluation results showed that the membership function value of 20.00 kg urea applied every 667 m^(2) was the highest,reaching 0.84,and the economic benefit was 1006.39 Yuan.In summary,the application of 20 kg urea every 667 m^(2) can promote the yield and economic benefits of Yushu turnip,and the research results provides a reasonable fertilization scheme for subsequent high-yield cultivation of Yushu turnip.
