摘要
有机无机肥配施是一种传统的施肥方式。该施肥方式能为作物提供持续、全面的养分,更好地促进作物生长,提高作物产量,改善产品品质。通过田间小区试验,研究了5种不同有机无机肥配施对小白菜叶片叶绿素含量、根系活力、产量及品质的影响。结果表明,无机肥配施生猪养殖垫料和稻草加菌剂2发酵而成的有机肥处理(处理E)的小白菜叶绿素含量高和根系活力相对较强,产量最高,较纯化肥处理提高了8.15%;品质方面,有机无机肥配施E处理的小白菜叶片维生素C含量最高,硝酸盐含量最低。因此,与其他处理相比,有机无机肥配施E处理更能促进小白菜的生长,增加产量和改善品质。
Combined application of organic and inorganic fertilizer is a traditional fertilization method, which can supply consistent and comprehensive nutrient for crops and can promote the growth, yield and quality of crop. Field plot experiment was conducted to study the influences of five different combined applications of organic and inorganic fertilizers on leaf chlorophyll content, root vigor, yield and quality of Chinese cabbage. The results showed that the treatment E, which combined application of inorganic fertilizer and organic fertilizer fermented by pig bedding with straw and bacterial agent 2, had higher leaf chlorophyll content, stronger root vigor and the highest yield, and the yield increased by 8.15% in comparison with treatment of pure chemical fertilizer; in terms of the quality of Chinese cabbage, the leaves in treatment E had the highest vitamin C content and the lowest nitrate content. Therefore, compared with the other treatments, growth, yield and quality of Chinese cabbage can be greatlv imnroved bv treatment E.
