| Abstract: | For planting soybean on reclaimed bog land, the experiment was conducted for proper proportion and amount of applied nitrogen, phosphate, potassium, fertilizers. The results showed that: it was necessary to apply phosphate fertilizer for planting soybean on reclaimed bog land and complementary with some potassium fertilizer. The suitable proportion was N:P 2O 5:K 2O=1:2:0.3. The suitable fertilizer amount per ha was N34.5kg, P 2O 5 69.5kg, K 2O 10.3kg. |
