| 摘 要： | [目的]为甘蓝生产合理施用有机肥提供科学依据。[方法]采用有机-无机肥料配合施用的方法种植甘蓝,在控制化肥用量一致的基础上,设计空白、3 750、7 500、11 250、15 000 kg/km2共5个不同猪粪有机肥用量的处理,测定土壤施肥前后的养分含量变化和甘蓝产量,探索不同猪粪有机肥施用量对土壤养分含量变化的影响。[结果]随着有机肥用量的增加,甘蓝产量增加。当有机肥用量为7 500 kg/hm2时,甘蓝产量最高为52 376 kg/hm2,进一步增大有机肥用量,甘蓝产量有下降趋势。[结论]施作为基肥7 500 kg/hm2的猪粪有机肥后甘蓝产量最高。增施有机肥能够提高土壤肥力,改良土壤性状。

| Abstract: | [ Objective] To provide the scientific basis for reasonable application of organic fertilizer in cabbage production： [ Method] 5 dif- ferent application rates treatments（ control, 3 750, 7 500, 11 250 and 15 000 kg/km2） of pig manure composting were conducted to investi- gate effects on cabbage yield and variations of nutrient content in soil. [ Result] More application of organic fertilizer could increase cabbage yield. The yield reached 52 376 kg/hm2 when application of organic fertilizer was 7 500 kg/hm2. The application of organic manure increased further, the growth trend of the cabbage yield slowed. [ Conelusion] Application of organic fertilizer could obviously increase cabbage yield and nutrient content in soil. |
