| 摘 要： | 通过对我省黑土肥力、以料施用及作物产量情况的监测，得出结论：⑴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；⑵作物养分的吸收大于养分的供给；⑶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
monitoring the stations about the blacksoil fertility, fertilizer application and crop
output in our province, the conclusions are gotten (1) The amount of organic fertilizer
applied is more than the chemical fertilizer. But the proportion of the pure nutrients is
opposite;(2) The part of nutrient absorbed by the crop is more than supporting;(3) In a
certain limitation, the crop yield will be increased by following increasing the amount of
fertilizer applied and keeping increasing the amount of fertilizer applied the potentialty
of increasing the yield will be smaller. |
