| 摘 要： | 目的]明确宁夏地区大豆的适宜播种时期。方法]以17个大豆品种为试材,分7期播种,研究不同播期对大豆生育期、产量、产量结构和农艺性状的影响。结果]宁夏地区4月23日至6月23日播种大豆均可正常成熟,其中4月23日至5月13日播种大豆产量较高;随着播期延迟不同大豆品种的产量、株高、主茎节数、单株粒数、百粒重呈递减趋势,生育天数缩短。结论]宁夏春播大豆适宜播种期是4月下旬至5月上旬,夏播早熟品种适宜播期为6月中旬至7月上旬。

| Abstract: | Objective] To make sure proper sowing date of Ningxia soybean.Method] 17 soybean varieties were tested in seven patches to research the effect of different sowing dates on growth period,yield,properties and agronomic traits of soybean.Result] The soybean sowed from April 23 to June 23 matured normally,those which were sowed from April 23 to May 13 had higher yield;the yield,plant height,node number on stem,grain number of single plant and 100-pellet weight gradually reduced and the growth period was shor... |
