有机无机肥配施对菊苣产量和品质的影响

Effects of Combination of Manure Fertilization and Chemical Fertilizer on Yield and Quality of Cichorium intybus

在粘、砂2种质地的紫色土上,研究了不同比例牛粪与化肥配施对菊苣生物学性状和理化性状的影响。结果表明:化肥配施牛粪可提高菊苣鲜草的产量,增幅高达2.8～8.8倍,尤其以有机氮∶化肥氮=3∶7的效果最佳。此外,化肥配施牛粪还显著增加了茎叶氮、磷和粗蛋白含量,降低了粗纤维含量,改善了菊苣的营养品质。因此,牛粪配施化肥种植牧草既可粪污还田,减施化肥,又可消化养殖污染,促进农牧和种养结合。

The effect of applying chemical fertilizer accompanied with caw manure on the growth of Cichorium intybus were studied in clay and sandy purple soils. The results showed that applying caw manure accompanied with chemical fertilizer could improve the yield of Cichorium intybus as 2. 8 .C 8. 8 times, among which the treatment of organic N ： inorganic N= 3 ： 7 had the best effects. Besides,applying chemical fertilizer accompanied with caw manure increased the contents of nitrogen, phosphorus and crude protein content significantly, and decreased the contents of crude fiber significantly, then improved the nutrient quality of chicory. So, planting pasture and applying chemical fertilizer accompanied with caw manure could be profitably decrease the application amount of chemical fertilizers, slurry to field and reduce the contamination from livestock,and it might be healthy to stockbreeding.
