Abstract

HE STUDY focuses on effect of the complementation between the plant growth promoting rhizobacteria (PGPR) such as Streptomyces erythrogriseus 2, Bacillus cereus 54-1, and Spirulina platinsis on the growth and the quantity of oil sesame under different rates of familiar manure 0, 2, 4 ton/fed. Results indicated inoculation mixture of Bacillus cereus54-1, Streptonyces erythrogreiseus sp 2 and Spirulina platinsis had the greatest effect on dehydrogenase activity (254.0 μg TPF/g dry soil), while root colonization Bacillus cereus54-1 , the uppermost values with 60 % colonization. The photosynthetic test was carried out where implementation of all microbes resulted in the highest chlorophyll a content with 2.03 mg/ g dry weight. Growth parameters was estimated, the treatment of bacteria Bacillus cereus54-1, Streptonyces erythrogreiseus sp 2 gave the highest values of Root length, shoot height, number of branches and shoot dry weight were 22.1,22.2 cm/plant root length 153,156.2 cm/plant shoot height,4.5,4.5 number of branches and 50.3,49.4 gm./plant shoot dry weight. Bacillus cereus54-1, Streptonyces erythrogreiseus sp 2 gave the highest values of shoot height, number of pods weight of 1000 seed and seeds Kg/fed number being, 169.7,159.0 cm/plant, pods number /plant and 5.4,5.97 weight of 1000 seed/plant, and 5.8,5.67seed Kg/Fadden respectively. However, the highest values of N, P and K were, 17.29, 7.9 and 62.20 (mg.kg -1 soil) obtained under the treatment of bacterial Bacillus cereus54-1, respectively. The highest seed oil percent was observed in treatments Bacillus cereus 54-1 and Streptomyces erythrogreiseus sp 2 where the heights seed oil percent was 51,48 Kg/fed compared to the control one it was 39 Kg/fed. Inoculation of the Spirulina platinsis gave high protein content 19.62 followed by bacterial of Bacillus cereus54-1 19.53. All these results were obtained by adding compost 2 ton/Fadden.
微生物群和有机改良剂提高了沙质土壤中芝麻的品质和数量
本研究主要研究了红红链霉菌2、蜡样芽孢杆菌54-1、铂螺旋藻等植物生长促生根瘤菌(PGPR)在不同投喂量下对油芝麻生长和产量的影响。结果表明,蜡样芽孢杆菌54-1、红绿链霉菌sp 2和铂螺旋藻混合接种对脱氢酶活性的影响最大(254.0 μ TPF/g干土),而根定殖的蜡样芽孢杆菌54-1的定殖率最高,为60%。在进行光合作用试验时,所有微生物的使用导致叶绿素a含量最高,为2.03 mg/ g干重。对生长参数进行了估算,蜡样芽孢杆菌54-1、红绿链霉菌sp 2处理的根长、茎高、枝数和茎干重分别为22.1、22.2 cm/株根长、153,156.2 cm/株茎高、4.5、4.5枝数和50.3、49.4 gm /株茎干重。蜡样芽孢杆菌54-1、红绿链霉菌sp . 2的茎高、千粒荚果数和种子Kg/采食数最高,分别为169.7159.0 cm/株、荚果数/株、5.4、5.97千粒重和5.8、5.67种子Kg/法登。氮、磷、钾含量最高,分别为17.29、7.9和62.20 (mg)。kg -1土壤)分别在蜡样芽孢杆菌54-1处理下获得。蜡样芽孢杆菌54-1和红绿链霉菌sp - 2处理的种子含油量最高,为51.48 Kg/次,高于对照的39 Kg/次。接种螺旋藻后蛋白质含量最高(19.62),其次为蜡样芽孢杆菌54-1(19.53)。所有这些结果都是在添加2吨/法登堆肥时获得的。
