摘　　要：为研究钼肥施用方式对宁夏旱区大豆生长和产量的影响,以大豆品种中黄318为供试材料,采用单因素随机区组设计,设置4个处理,分别为CK(常规施肥,不施钼肥)、T_(1)(钼肥拌种)、T_(2)(始花期叶面喷施钼肥)和T_(3)(钼肥拌种+始花期叶面喷施钼肥),测定该作物根系特征、产量和产量构成以及地上部干物质量。结果表明,T_(1)的主根长和侧根数最高,分别为24.19 cm和11.03个;地上部干物质量最高,为2160.0 kg/hm^(2);以T_(1)产量最高,为1226.70 kg/hm^(2),较CK、T_(2)和T_(3)分别高33%、11%和22%。对产量和生长指标进行分析,结果表明,以钼肥拌种处理(T_(1))大豆的生长性状及产量最好。综合来看,在宁夏旱区及相关地区可推广钼肥拌种处理,以促进大豆生长,提高产量。To investigate the effects of molybdenum fertilizer application methods on the growth and yield of soybeans in arid areas of Ningxia,the soybean variety Zhonghuang 318 was used as the test material,a single factor random block design was adopted,and 4 treatments were set up,namely CK(conventional fertilization without molybdenum fertilizer),T_(1)(molybdenum fertilizer mixed with seeds),T_(2)(molybdenum fertilizer foliar spraying at the beginning of flowering period),and T_(3)(molybdenum fertilizer mixed with seeds+molybdenum fertilizer foliar spraying at the beginning of flowering period),the root system characteristics,yield and yield composition,as well as aboveground dry matter mass of soybean were determined.The results showed that the main root length and lateral root number of T_(1)were the highest,at 24.19 cm and 11.03,respectively;the highest aboveground dry matter mass was 2160.0 kg/hm^(2);the yield of T_(1)was the highest yield was 1226.70 kg/hm^(2),which was 33%,11%,and 22%higher than CK,T_(2),and T_(3),respectively.Analysis of yield and growth indicators showed that the growth traits and yield of soybean treated with molybdenum fertilizer(T_(1))were the best.Overall,molybdenum fertilizer seed mixing treatment can be promoted in arid areas and related regions of Ningxia to promote soybean growth and increase yield.
