摘要
为检验黄淮海夏大豆在华南地区春夏秋三季快繁加代的可行性,确定最佳播种期和收获期,以广适大豆品种中黄39为材料,于2019年2月10日-10月10日,在广西南宁进行分期播种试验,观察其在不同播期下的生育时期和农艺性状表现,并分别于鼓粒期(R6)、生理成熟期(R7)和完熟期(R8)摘荚风干,测定籽粒发芽率。结果表明:中黄39可在广西南宁1年连续繁育3代。第一季最佳播期为2月中、下旬,于5月中、下旬收获;第二季最佳播期为6月下旬至7月上旬,于9月中旬收获;第三季最佳播期为9月中、下旬,于12上、中旬收获。在生理成熟期(R7)摘荚风干后籽粒的发芽率最高,为最佳收获时期。中黄39不同季度种植,秋播时其主要农艺性状表现最好,其次是春播,夏播产量最低。
In order to test the feasibility of three successive generations including spring,summer and autumn of soybean in Huang-Huai-Hai region,and determine the optimum dates of sowing and harvest,Zhonghuang 39,a summer soybean cultivar was planted by instalments from February 10th,2019 to October 10th,2019 in Nanning,Guangxi.The growth stages and agronomic characteristics were observed after different sowing dates,and pods were picked and dried to determine the germination rate of seed in filling seed(R6),beginning maturity(R7)and full maturity(R8)stage respectively.The results showed that Zhonghuang 39 could breed for three generations in a year in Nanning,Guangxi.The best sowing time of the first crop was in mid-late February and harvest in the mid-late May,the best sowing and harvest dates for the second crop were from late June to early July and middle September,respectively,and those for the third crop were in mid-late September and early-mid December,respectively.The germination rate of seeds was the highest after pod picking and air drying at the beginning maturity stage(R7),which was the best harvest time.The main agronomic characters of Zhonghuang 39 were the best in autumn sowing,followed by spring and summer sowing.
