Abstract

The aim of this study was to clarify the phytochemical property evaluation of Roselle plants grown under bio Azotobacterine (Azotobacterchroococcum) and phosphorein (Bacillus polymyxa) and mineral (N, P and K fertilizers at the rates of 25, 50 and 100% from the doses recommended by Ministry of Agriculture) fertilizers applied in different types of soil. Samples of Roselle plants were obtained from different soils (clay soil at Dar El-Ramad farm, sandy loam and saline loamy sand soil at Demo farm, Faculty of Agriculture) at El-Fayoum governorate conditions. Moreover, some of the phytochemical properties (N, P and K percentage in roselle herb and its uptake, photosynthetic pigments (chlorophyll A, chlorophyll B and carotenoids), anthocyanin pigment and pH value) of roselle plants (Hibiscus sabdariffa, L.) under different soils were determined. The data obtained showed that, bio and mineral (NPK) fertilizers increased the above compositions of roselle plants under different soils of experiment. The maximum increase of these compositions was obtained by the treatment clay soil × 100% NPK + bio fertilizers, followed by clay soil × 50% NPK + bio fertilizers as compared to saline loamy sand soil × non fertilizer treatment, although, the differences between these treatments and mineral fertilizer at the rate of 100% NPK alone were insignificantly. Therefore, it is economically and environmentally recommended to inoculate roselle seeds with mixture of Azotobacter + Bacillus and fertilize these inoculated plants with 50% NPK for improve chemical compositions (N, P and K percentage in roselle herb and its uptake, photosynthetic pigments (chlorophyll A, chlorophyll B and carotenoids), anthocyanin pigment and pH value) of roselle plants under clay soil.

不同类型土壤中生物和矿物肥料对玫瑰茄（Hibiscus sabdariffa，L.）植物化学特性的影响

本研究的目的是阐明在不同类型土壤中施用生物固氮菌（Azotobacterchroococcum）、磷蛋白（Bacillus polymyxa）和矿物肥料（农业部推荐剂量的25%、50%和100%的N、P和K肥料）的玫瑰茄植物的植物化学性质评估。玫瑰茄植物的样品是从El Fayoum省条件下的不同土壤（Dar El Ramad农场的粘土、农业学院Demo农场的沙壤土和含盐壤土）中获得的。此外，还测定了不同土壤条件下玫瑰茄（Hibiscus sabdariffa，L.）的一些植物化学特性（玫瑰茄中N、P、K的百分比及其吸收、光合色素（叶绿素A、叶绿素B和类胡萝卜素）、花青素色素和pH值）。结果表明，在不同的试验土壤条件下，生物和矿物肥料均能提高玫瑰茄植株的上述组成。粘土×100%NPK+生物肥料处理的这些成分增加幅度最大，其次是粘土×50%NPK+生态肥料处理，与含盐壤土×无肥料处理相比，尽管这些处理与单独使用100%NPK的矿物肥料之间的差异不显著。因此，在经济和环境上建议用固氮菌+芽孢杆菌的混合物接种玫瑰茄种子，并用50%的NPK对这些接种的植物进行施肥，以改善玫瑰茄草本植物的化学成分（N、P和K百分比及其吸收、光合色素（叶绿素A、叶绿素B和类胡萝卜素），花青素色素和pH值）。关键词：玫瑰茄，芙蓉，氮，磷，钾，生物肥料，土壤类型，盐度，化学成分。
