我国农村使用量较大的碳铵在南方水田一般利用效果30%左右。腐肥与化肥混合使用能形成腐植酸盐类,在一定程度上能减少化肥的损失,提高可给养分的利用效果,促进水稻的产量提高。本试验布置在同样土壤肥力条件下,腐肥混合化肥与单施化肥进行比较试验,探讨腐肥对水稻吸收可给态氮、磷、钾三要素的有利作用与对水稻产量的影响。 The use of ammonium bicarbonate in rural areas in China is generally about 30% of the effect of paddy fields in the South. Combined use of rotting fertilizer and chemical fertilizer can form humic acid salts, which can reduce the loss of chemical fertilizer to a certain extent, improve the utilization of nutrients available and promote the increase of rice yield. The experiment was conducted under the same soil fertility conditions, comparing fertilizers with chemical fertilizers to test the beneficial effects of fertilizers on the absorption of nitrogen, phosphorus and potassium by rice and their effects on rice yield.
