【摘要】 通过渭北旱原永寿地区小麦肥效田间试验及品质分析表明:旱原小麦施肥既能提高产量,又能保持和改善品质,NP 配合施用是提高肥效的有效措施。确定了亩产200～250公斤小麦需施 N 肥5～7公斤,P₂O₅4～5公斤,适宜的 NP 比为1∶0.6～0.8,结果还证明,综合配套技术的应用是旱原小麦稳产高产的可靠保证。更多还原

【Abstract】 A number of field trials on fertilizer efficiency at Yongshou experimentalbase were conducted and wheat quality was analyzed.Results showed that fer-tilizers applied to wheat on the rainfed highland can not only increase theyield but also improve its quality,and that the mixture application of N/Pfertilizers with the proper ratio of 1 to 0.6-0.8 was the best way to improvefertilizer use efficiency.Also,it was determined that 200-250kg of wheatyield per mu required 5-Tkg of pure N fertilizer and 4-5kg of P₂O₅.The ex-periments also indicated that the integral techniques of cultivation was a re-liable gurantee for stable and high-yielding wheat yields on rainfed highland更多还原
