近年,随着旱地吨粮工程建设的发展和旱粮作物种植结构的改革,大豆种植面积逐年扩大,由于我省旱地土壤耕层浅、肥力低,特别是新垦红壤养分贫瘠,大豆生长差,产量一般在100千克以下,国内外研究和应用证明,大豆接种根瘤菌剂是一项有效的增产措施。我们引进四株较好菌株进行筛选,并在我省红壤区的红山,常山、义乌、兰溪、东阳、潮州以及乔司等地进行了多点效果测定。
In recent years, with the development of the dry land tonnage grain project construction and the reform of the crop planting structure of dry land, the planting area of soybean has been expanded year by year. Due to the shallow tillage and low fertility of dry land in our province, especially the poor reclamation of red soil, Production is generally below 100 kg, research and application at home and abroad proved that soybean inoculation rhizobia agent is an effective stimulation measures. We introduced four strains of better screening, and in the red soil area of Hongshan, Changshan, Yiwu, Lanxi, Dongyang, Chaozhou and Qiao Si and other places for a multi-point effect determination.
