通过等氮量的沤制蓝藻湖靛、人畜粪和碳酸氢铵作为早、晚稻追肥肥效的比较试验,以及通过沤制蓝藻湖靛对早、晚稻不同施用量的追肥和基肥的试验说明,沤制蓝藻湖靛的肥效与碳酸氢铵相似;在一定数量的范围内,其施用量与水稻产量呈正相关。 Through the same amount of nitrogen, such as cyanobacteria Lake indigo, manure and ammonium bicarbonate as early and late rice fertilizer efficiency of the comparative test, and through the control of blue algae Lake on the early and late rice topdressing and basal fertilizer application rates of different test instructions, The effect of producing blue-green algae lake is similar to that of ammonium bicarbonate. Within a certain amount of range, the application rate is positively correlated with the yield of rice.
