摘要
基于2018—2023年间在江西、湖南、湖北等9个县(市)对赣芝14号开展试验示范的数据,分析了赣芝14号多年多点试验在种植土壤、培种方式、播种方式、播种时间、种植密度等不同条件下保持高产的原因。结果表明:品种比较试验中赣芝14号产量为1526.25~2049.30 kg/hm^(2),平均产量为1783.93 kg/hm^(2),较当地对照品种增产了11.65%~75.24%,平均增产35.58%,有较好的丰产性;条播较撒播增产效果更为明显;能够适应不同土壤条件;最适播期为6月中旬—7月上旬;最适播植密度为18万~22万株/hm^(2)。综上,赣芝14号是一个兼具高产、稳产、广适、低镉、抗性好等特性的优良黑芝麻新品种,适合在我国江西、湖南、湖北等黑芝麻产区省份种植应用。
Based on the experimental demonstrations results which were carried out in 9 counties(cities)in Jiangxi Province,Hunan Province and Hubei Province from 2018 to 2023,the reasons why Ganzhi No.14 could maintain high yield under different conditions of planting soil,sowing method,sowing time and planting density were analyzed.The results showed that the yield of Ganzhi No.14 was 1526.25~2049.30 kg/hm2,and the average yield was 1783.93 kg/hm2,which was 11.65%~75.24%higher than that of the local control species,and the average increase was 35.58%,which revealed that it had good fertility.The yield increase effect of drill sowing was more obvious than broadcast sowing,which could adapt to different soil conditions.The optimum sowing period was from mid-June to early July.The optimal planting density was 180,000~220,000 plants/hm2.Therefore,Ganzhi No.14 is an excellent new black sesame variety with high and stable yield,wide adaptability,low cadmium accumulation and good resistance,which is suitable for planting and application in south black sesame producing areas such as Jiangxi,Hunan and Hubei.
