摘要
采用田间小区试验,研究不同有机肥对水稻产量及产量构成因素的影响。结果表明,施20%猪粪代替20%的化学氮肥处理、施10%的猪粪型生物有机肥代替10%的化学氮肥处理和施20%沼肥代替20%的化学氮肥处理的水稻产量较高,分别较不施肥处理提高了103.49%、81.62%和74.64%,较纯化肥处理提高了38.67%、23.77%和19.02%。
A field plot experiment was conducted to study effects of organic fertilizer on yield and yield composition factors of rice.The results showed that the rice yield was much higher when applying 20% pig manure instead of 20% chemical nitrogen fertilizer,applying 10% pig manure decomposed organic fertilizer instead of 10% chemical nitrogen fertilizer or applying 20% biogas fertilizer instead of chemical nitrogen fertilizer,which increased by 103.49%,81.62% and 74.64% than that of non-fertilizer treatment and 38.67%,23.77% and 19.02% than that of pure chemical fertilizer treatment,respectively.
