结球甘蓝测土配方施肥同田对比研究

One-field Comparative Study on Soil Testing and Fertilizer of Cabbage

[目的]验证不同肥力水平下蔬菜结球甘蓝的最佳施肥量在实际应用中的效果,指导大面积生产。[方法]选取高肥力与中肥力地块2组,各设置无肥区、习惯施肥和配方施肥区3个处理,研究测土配方施肥对蔬菜结球甘蓝产量及经济效益的影响。[结果]高肥力地块配方施肥区与习惯施肥区相比,增产率达到了4.8%,与无肥区相比,增产率达到了22.4%;中肥力地块配方施肥区与习惯施肥区相比,增产率达到了4.3%,与无肥区相比,增产率达到了26.8%,增产效果显著,经济效益明显。[结论]在今后结球甘蓝生产中,应大量推广使用配方施肥技术,既提高产量又增加效益,同时提高肥料利用率,减少环境污染和肥料副成分的残留,对可持续农业发展意义深远。

[Object] The aim of this research was to test the effect of the best fertilizer rales of cabbage in different soil tertility levels in practical application and Io guide the production in large tracts of land. [Method] Non-fertilizing,conventinnal fertilization and formula fertilization treatments were taken on the high fertility and medium fertility soil, the soil testing and formulated fertilization on vegetable cabbage yield and economic effect were studied. [Result] The results showd that in the high fertility test formula fertilization plot, comparing with the eonventional fertilization plot, the yield rate was increased and reached 4.8%, anti comparing with the non-fertilizing plot, the yield rate reached 22.4%. in the medium fertility test formula plot. comparing with the conventional fertilization plot, the yield rate reached 4.3%, and comparing with the non-fertilizing plot, the yield rate reached 26.8%. The production was increased greatly, and the economic benefit is obvious. [Conclusion] In the future,the fertilizer technology should be popularized in cabbage production, since it not only increase the production and the benefits but also improve the fertilizer using efficiency and reduce the fertilizer pollution to the environment, which is of far-reaching significance to the sustainable development of agriculture.
