【目的】研究桂春8号在不同地区间作条件下适宜的间作播期和夏繁时间,为广西大豆生产及大豆间套种提供参考。【方法】2011年以桂春8号为试材,在广西武宣县、武鸣县和都安县进行播期试验。【结果】在不影响间作主体作物的条件下,武宣县3月中上旬播种大豆产量为1459.5~1597.5kg/ha;武鸣县2中旬~3月下旬播种大豆产量为2476.5~2877.5kg/ha;都安县2月初~3月上旬播种大豆产量为2262.0~2499.0kg/ha,6月上旬~7月上旬为2122.5~2409.0kg/ha。【结论】在间作条件下,桂春8号在武宣县适宜的播期为3月中上旬;在武鸣县适宜的播种期为2月中旬~3月下旬;在都安县适宜的播期为2月初~3月上旬,夏繁适宜的播期为6月上旬~7月上旬,且在适宜的播期内可适时早播。
【Objective】 The objective of this study was to study the appropriate sowing date and summer time of Guichun 8 in intercropping in different regions to provide references for soybean production and inter-soybean intercropping in Guangxi. 【Method】 In 2011, Gui Chun 8 was used as sowing material in sowing in Wuxuan County, Wuming County and Du’an County in Guangxi Province. 【Result】 Sowing soybean yield was 1459.5-1597.5kg / ha in mid-to-early March in Wuxuan County, and mid-late March to late March in Wuming County was 2476.5-2877.5kg / ha. The output of soybean in the early February to early March in Du’an County was 2262.0 ~ 2499.0kg / ha, and from early June to early July was 2122.5 ~ 2409.0kg / ha. 【Conclusion】 Under the intercropping condition, the suitable sowing date of Guichun 8 in Wuxuan County was in the middle of March; the suitable sowing period in Wuming County was from mid February to the end of March; the suitable sowing date in Du’an County was From early February to early March, suitable summer sowing date is from early June to early July, and sowing can be carried out in suitable sowing date.
