摘　　要：为优化毕节地方线椒施肥技术、提高线椒生产经济效益,采用了"3414"完全实施方案对毕节线椒、大方皱椒、黔西线椒的施肥技术进行研究。试验表明:毕节地方线椒的最优施肥方案为N16.41kg/667m2、P2O59.30kg/667m2、K2O18.96kg/667m2,N∶P∶K为1∶0.57∶1.15,干椒产量可达208.57kg/667m2;N、P、K平均肥料利用率分别为29.88%、26.97%、32.20%;土壤的肥力性状供N水平中下等、供P水平中上、供K水平中等;平均每667m2纯收入达1823.61元,投产比为1∶3.46,经济效益显著。In order to optimize fertilizer application technique and improve economic benefits of Bijie linear pepper production, some local hot pepper varieties such as Bijiexianjiao, Dafangzhoujiao and Qianxixianjiao were used as experimental materials in this study by using the 3414 design. The results showed that the optimal fertilization pattern for the Bijie linear pepper was 16.41kg N per 667m2, 9.30kg P2O5 per 667m2 and 18.96kg K2O per 667m2. The dry fruit yield could reached 208.57kg per 667m2 when the N∶P∶K was 1∶0.57∶1.15. The utilization rate of N, P and K was 29.88%, 26.97% and 32.20%, respectively. The soil fertility was below the middle N level, above the middle P level and at the middle K level. And the average net income reached 1823.61 RMB yuan per 667m2 with the input-output ratio of 1∶3.46 and significant economic profit.
