摘  要：
以十字花科蔬菜小松菜为研究试材,采用茶渣有机无机活性肥、井上政微生物肥料和黄腐酸钾3种肥料和3个施肥水平及3种种植密度的三因素三水平正交设计方法,研究最佳有机肥的施用方法和最适种植密度。结果表明:无论是单株产量,包括叶重、叶柄重,还是叶柄重/单株重或单位面积产量,决定经济性状和出口商品利用率大小的主要因子是种植密度,其次是施肥量,肥料种类影响最小。施用茶渣有机无机活性肥最佳施肥量为1 125 kg.hm-2;在施用345 kg.hm-2NPK复合肥基础上,井上政微生物肥料和黄腐酸钾的最佳施用量均为300 kg.hm-2。提高小松菜的出口商品利用率的最适种植密度为36万株.hm-2。获得最高产量和经济效益的组合是A2B2C3,即施用300 kg.hm-2井上政微生物肥和345 kg.hm-2复合肥,种植密度为45万株.hm-2。

摘  要：
In order to study effects of fertilizer kinds and rates as well as planting density on growth and yield of Komatsu dish under facility cultivation condition,an orthogonal design experiment of 3 kinds of fertilizers(tea dregs organic-inorganic compound fertilizers,inoue Masa microbial fertilizer and fulvic acid potassium),3 fertilization levels and 3 kinds of planting density(27,36,and 45×104 plant· hm-2)was selected.The results of the experiment showed that improvement of growth and increases of yields of Japanese Komatsu dish generally followed the order:plant densities>fertilizer rates>fertilizer kinds.Optimum application rates of tea dregs organic-inorganic compound fertilizers was 1 125 kg·hm-2;while inoue Masa microbial fertilizer and fulvic acid potassium was all 300 kg·hm-2 under the condition of application of 345 kg·hm-2 NPK compound fertilizer.Optimum planting density of Komatsu dish for improving the utilization rate of export goods was 36×104 plant·hm-2.The highest yields and economic benefits of Komatsu dish was obtained from the treatment with 300 kg·hm-2 of inoue Masa microbial fertilizer and 45×104 plant·hm-2 of planting density.
