通过田间试验,研究了苏南地区2006—2007年稻麦轮作体系下,施用菜粕堆肥有机无机复混肥(RCC)、猪粪堆肥有机无机复混肥(PMC)、中药渣堆肥有机无机复混肥(CMC)和化肥(CF)对小麦和水稻;产量及氮素利用率的影响.结果表明:各施肥处理的小麦和水稻产量均显著高于对照;RCC、PMC和CMC处理的小麦产量分别比化肥处理(6760kg·hm-2)减少了13.1%、32.2%和39.3%;而不同有机无机复混肥处理的水稻产量(8504～9449kg·hm-2)则显著高于化肥处理(7919kg·hm-2),增产率达7.4%～19.3%.在小麦季,RCC、PMC和CMC处理的地上部干物质量、氮素积累量、氮素利用率普遍低于化肥处理,而水稻季则显著高于化肥处理或与之相当.综上,在苏南稻麦轮作体系下,3种有机无机复混肥均能提高水稻产量及氮素利用率,其中菜粕堆肥处理提高效果最为显著.
A field experiment was conducted to study the effects of organic and inorganic fertilizer (RCC), pig manure composting organic and inorganic fertilizer (PMC), Chinese medicine residue composting organic and inorganic complex The results showed that the yield of wheat and paddy were significantly higher than those of the control. The yield of wheat treated with RCC, PMC and CMC was significantly higher than that of the control Which was 13.1%, 32.2% and 39.3% less than that of fertilizer treatment (6760kg · hm-2) respectively. However, the yield of rice with different organic-inorganic compound fertilizer treatments (8504-9949kg · hm-2) · Hm-2), and the yield was 7.4% -19.3% .In the wheat season, the aboveground dry matter, nitrogen accumulation and nitrogen utilization of RCC, PMC and CMC treatments were generally lower than those of chemical fertilizers, Significantly higher than that of chemical fertilizers or comparable.In conclusion, under the system of rice rotation in South Jiangsu, all three kinds of organic-inorganic compound fertilizers can increase the yield and nitrogen use efficiency of rice, in which the effect of rapeseed compost treatment is the most significant.
