不同肥料配比对设施青菜生产的影响

Effects of Different Fertilizer Ratios on Greenhouse Cabbage Production

为探索不同肥料配比对设施青菜产量和品质的影响,以青梗菜品种夏升1号为试验材料,开展不同施肥试验研究。结果表明,青菜生长过程中,应用配方肥和缓释肥、有机肥代替部分化肥,减少化肥纯量22.1%、18.3%和2.3%,青菜长势良好,产量较常规施肥有所增加,虽肥料投入成本增加,但增产效果显著,各处理青菜的经济效益都优于常规施肥。其中,每667 m2基肥施商品有机肥300 kg、硝态氮型配方肥(22-9-9)30 kg,追施尿素20 kg,既能减少化肥投入、降低生产成本,又能增加作物产量、提高种植收益。

In order to explore the effects of different fertilizer ratios on the yield and quality of greenhouse cabbage,the fertilization experiment was carried out with Xiasheng No.1 as the experimental material.The results showed that the application of formula fertilizer,slow-release fertilizer and organic fertilizer instead of chemical fertilizer reduced the purity of chemical fertilizer by 22.1%,18.3%and 2.3%,the growth of cabbage was good,and the yield was higher than that of conventional fertilization.Although the cost of fertilizer input increased,the effect of increasing yield was significant,and the economic benefits of each treatment was better than that of conventional fertilization.Applying 300 kg of commercial organic fertilizer,30 kg of nitrate-N fertilizer(22-9-9)and 20 kg of urea per 667 m2 could not only reduce the input of chemical fertilizer and production cost,but also increase the crop yield and improve the planting income.
