摘要： 研究NPK施肥量对饲用菊苣生产性能的影响。结果表明,在北京地区中等肥力土壤,春播菊苣在莲座叶丛期施尿素600kg/hm2,过磷酸钙450kg/hm2,氯化钾150kg/hm2为最佳施肥方案,不仅能提高干物质产量和单株重量,促进其快速再生,而且每公顷增加净收入达452.9元,产生了较好的经济效益。

Abstract: A study of the effects of nitrogenous,phosphate,and potash fertilizers on the productive characteristics of Cichorium intybus L.shows that in a plot of medium fertility in the Beijing area,the best fertilizing time for Cichorium intybus L.is spring when the plant puts forth rosette leaf bunch,and the proportionate amount of fertilizers per square hectometer is 600 kg of urea,450 kg of calcium superphos- phate,and 150 kg of potassium chloride.The treatment not only increases the Cichorium intybus L.yield of dry matters and the single plant weight,but speeds the regeneration of the plant as well.The yearly net income increases by 452.9 yuan(RMB) per square hectometer.

Key words: Cichorium intybus L., Fertilization, Productive characteristics
