摘要
[目的]研究适合胡萝卜生长的生物菌肥用量,为胡萝卜高效优质栽培提供科学依据.[方法]以橙胡萝卜和华微生物氮磷钾A50为原料,研究不同浓度的生物菌肥对胡萝卜长势、胡萝卜素、叶绿素及肉质根生长的影响.[结果]在施加570 kg/hm2生物菌肥时胡萝卜的长度、粗度与肉质根重量均达到最大值,但继续增加施肥量时其反而减少.胡萝卜中叶绿素与胡萝卜素的含量均在施加570 kg/hm2生物菌肥时最高.[结论]最适合胡萝卜生长的华微生物氮磷钾A50的浓度是570 kg/hm2,此时胡萝卜产量最大,营养价值最高.
Abstract
[Objective] To research the suitable dosage of bio-bacterial manure for the growth of carrot, and to provide scientific basis for the high efficiency and high quality cultivation of carrot. [ Method] With orange carrot and Huawei biological NPK A50 as the raw materials, the effects of different concentrations of bio-bacterial manure on the growth, carotene, chlorophyll and fleshy root growth of carrot were researched. [ Result] the length, roughness and fleshy root weight of carrot all reached the maximum values when applying 570 kg/hm2 bio-bacterial ma-nure. However, when the bio-bacterial manure was higher than 570 kg/hm2, they reduced. The contents of chlorophyll and carotene were the highest at 570 kg/hm2 bio-bacterial manure. [ Conclusion] The most suitable concentration of Huawei biological NPK A50 was 570 kg/hm2 for the growth of carrot. Under this condition, the yield and nutritional value of carrot were both the highest.
