闽南地区油菜生育期间气温较高,湿度较大,日照较短,无明显越冬期,1～2月份平均温度为12℃以上。近几年来,油菜种植面积有了较大发展,尤其是甘蓝型油菜种植面积正逐步扩大。为了探明不同熟期的甘蓝型油菜的适宜播种期和不同播种期对生育期、植株性状及产量的影响,于一九八○年在本所进行了甘蓝型油菜早熟和迟熟品种的分期播种试验。
During the growth of rapeseed in southern Fujian, the temperature was higher, the humidity was higher, the sunshine was shorter, no obvious wintering period, and the average temperature in January-February was above 12 ℃. In recent years, rapeseed area has made great progress, especially the planting area of rapeseed is gradually expanding. In order to determine the appropriate sowing dates and the effects of different sowing dates on the growth period, plant characters and yield of Brassica napus at different maturity stages, the staging of precocious and late ripening of Brassica napus was carried out in our firm in 1980 Sowing test.
