摘　　要：为探索花生在青海地区的适宜播期,本研究以花生品种白沙171为研究材料,分析不同播种期对白沙171的生育期、农艺性状、产量和品质的影响。结果表明,处理3(4月20日播种)表现最好,其出苗率、带壳两果、带壳一粒果、带壳一粒果重量、2粒果长、2粒果最大宽、果仁长、果仁宽、单株果数、饱果、百果重、百仁重、公顷产量、含油量、蛋白质、油酸、亚油酸均最高,其次是处理4(4月28日播种),处理1(4月9日播种)表现最差。综合考虑农艺性状、产量以及果实品质,青海地区大田花生的适播期为4月20日—4月28日,最晚不应晚于5月5日。To explore the suitable sowing period for peanut in Qinghai region,this study used the peanut variety Baisha 171 as the research material,and analyzed the effects of different sowing periods on the growth period,agronomic traits,yield,and quality of Baisha 171.The results showed that Treatment 3(sown on April 20th)was the best,with the highest emergence rate,two fruits with shells,one fruit with shell,weight of one fruit with shell,length of two fruits,maximum width of two fruits,length and width of kernels,number of fruits per plant,full fruit,weight of 100 fruits,weight of 100 kernels,hectare yield,oil content,protein,oleic acid,and linoleic acid.Treatment 4(sown on April 28th)performed the better,Treatment 1(sown on April 9th)was the worst.Taking into account agronomic traits,yield,and fruit quality,the suitable sowing period for field peanuts in Qinghai region is from April 20th to April 28th,and should not be later than May 5th at the latest.
