- 摘要:
- 通过对我省黑土肥力、肥料施用及作物产量情况的监测,得出结论: ( 1)有机肥实物施入量基本上大于化肥施入量,折纯施入量比例相反; ( 2)作物养分的吸收大于养分的供给; ( 3)施肥量在一定限度内,作物产量随肥料施入量的增加而增加,继续增加施肥量,增产潜力较小。
- Abstract:
- By moni to ring the statio ns about the blacksoi l ferti li ty , fer tili zer applicatio n and crop o utput in our province, the co nclusions are go t ten: ( 1) The amo unt of orga nic fertili zer applied is more than the chemical fer tili zer. But the proportion o f the pure nut rient s i s o ppo site; ( 2) The part of nut rient abso rbed by the crop i s mo re than suppo rting; ( 3) In a certain limi ta tion, the crop yield will be increased by follow ing increasing the amount of ferti li zer applied and keeping increasing the amount o f ferti li zer applied the potentialty o f increasing the yield will be smal ler.
