固体肥种类与施肥量对穴盘小白菜生长及产量品质的影响

Effects of types and applying amount of solid fertilizer on growth, quality and yield of non-heading Chinese cabbage under container culture

摘要: 试验以小白菜品种“矮脚黄”为材料，以72孔黑色聚乙烯塑料穴盘为栽培容器，采用有机复合基质为栽培基质，研究固体肥种类与施肥量对穴盘小白菜生长、产量、品质及经济效益的影响。结果表明，合理的肥料配比对提高小白菜品质有显著作用，可提高小白菜可溶性糖、可溶性蛋白质和Vc含量，而硝酸盐含量明显下降。在有机肥中加入适当的无机复合肥、生物复合肥可满足小白菜生长旺期对肥料需求量大的要求，发挥基质栽培的最大肥效，使小白菜单株鲜重及整体产量达最高水平，获得较好的经济效益。

Abstract: Effects of different solid fertilizers and their applied amount on growth, yield, quality and economic benefit of non-heading Chinese cabbage“Aijiaohuang”cultivated in container were studied. The results show that the contents of soluble sugar, soluble protein and vitamin C of non-heading Chinese cabbage are improved significantly by application of reasonable compound of solid fertilizer. The nitrate content declines remarkably. The addition of inorganic fertilizer and biological fertilizer into organic fertilizer can meet the nutrient demands of non-heading Chinese cabbage during quick growth period, meanwhile the high yield and benefits can be achieved.
