Subtropical Plant Science 小白菜施用不同有机肥的产量及效益比较分析 陈龙杰 (厦门市翔安区农林水利局，福建 厦门 361100) 摘 要：以小白菜Brassica campestris subsp. chinensis var. communis 为试材，通过田间试验，研究同等肥料成 本条件下，豆粕有机肥、绿营高生态肥、宝大牌有机肥及鸡粪有机肥配施化肥对小白菜株高、叶片数、单株重 及产量、效益的影响。结果表明，4 种有机肥配施化肥，小白菜株高、叶片数、单株重和产量、净收入明显高 于对照，其增幅分别为 7.04% ～16.08%、20.43% ～23.66% 、108.07% ～163.60%和 158.06% ～232.26% 、250.28% ～ 408.09% ，且差异极显著。其中以绿营高生态肥种植的小白菜产量(15 451.5 kg ·hm-2) 、净收入(2.858 万元·hm-2) 最高，分别较鸡粪肥处理增加 28.75% 、43.26% ，差异极显著。经产量效益分析表明，绿营高生态肥配施化肥 可促进小白菜增产增收，其用量与方法为生态肥 3349.95 kg ·hm-2 配施基肥型复合肥(15-15-15) 300 kg ·hm-2 ，作 为基肥一次性施入收益最佳。 关键词：有机肥；化肥；蔬菜；产量；效益 Doi: 10.3969/j.issn.1009-7791.2017.01.018 中图分类号：S634.3 文献标识码：A 文章编号：1009-7791(2017)01-0092-04 Effect of Different Organic Fertilizers on Yield and Benefit in Pak-choi CHEN Long-jie (Agricultural and Forestry Bureau of Xiang’an District, Xiamen 361100, Fujian China) Abstract: The effects of combined application of different kinds of organic fertilizers (with soybean meal organic fertilizer, Lüyinggao ecological fertilizer, Baoda organic fertilizer and chicken manure organic fertilizer) and chemical fertilizers on plant height, leaf numbers, weight per plant, yield and economic benefit of pak-choi (Brassica campestris subsp. chinensis var. communis) were studied in field. The results indicated that the fertilization showed a significantly impact on the vegetables height, leaf number, weight, yield and net income with an increase rate of 7.04%—16.08%, 2
