等氮条件下有机无机肥配施对大棚和露地青菜产量及品质的影响
Effects of organic manure?chemical fertilizer ratio on paKchoi yield and quality in greenhouse and open field under the same N fertilizer rate
摘要
Abstract
The effects of pig manure compost and chemical fertilizer applied alone or combined ap-plication on pakchoi yield and quality in greenhouse or open field were studied.Under the same N con-dition(150 kg?hm2 ),greater ratio of inorganic nitrogen achieved the higher yield and better economic benefits.The production and efficiency of pakchoi in greenhouse was significantly higher than that in the open field.The nitrate content of pakchoi in greenhouse were significantly higher than that in open field,while the Vc content,the protein content and the soluble sugar content in pakchoi were sig-nificantly lower in open field than in greenhouse.Regardless of cultivation methods,the nitrate con-tent of pakchoi reduced,the Vc content,the protein content and the soluble sugar content of pakchoi increased with the increase of organic nitrogen.Organic fertilizer ratio was helpful to improve the quality of pakchoi,and the effect was more evident in the facilities production.关键词
