| 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. |
