赵光农垦局自1949—1964年的资料统计,大豆亩产量平均为114.5斤,而不同年份产量的变化幅度较大。 大豆产量所以不高、不稳的原因较多,主要是我省北部地区生育期短,前期地温低,土壤养分转化缓慢影响大豆生长。另一个重要原因是连年种植作物而施肥较少,地力减退。为此,我院生物物理研究室与赵光农垦局农科所共同研究了氮磷营养对该地区大豆生长发育以及植株体内氮代谢的影响。
Zhao Guangnong Reclamation Bureau data from 1949 to 1964 statistics, soybean yield average 114.5 kg, while the output of different years, a larger margin of change. Soybean production is not high, unsteady for many reasons, mainly in the northern region of our province has a short growth period, early low ground temperature, soil nutrients slowly affect soybean growth. Another important reason is that crop plants are planted year after year with less fertilizer and fertility. To this end, the Institute of Biophysics and Zhao Guangnong Bureau of Agricultural Reclamation co-study of nitrogen and phosphorus nutrition on soybean growth and development in the region and plant nitrogen metabolism.
