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。
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 fulvie acid potassium） ,3 fertilization lev- els 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^-2under 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 × 104plant.hm-z. The highest yields and economic ben- efits 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.
