| 1. | Some of the early reports of specific genes were based on inadequate data or arose from poor interpretation of available data . 早期关于专性基因的一些报道,是根据不充分的资料和现有资料的粗浅解释提出的。 |
| 2. | The liverworts divides into three types in the nature reserve , obligate , commonly facultative and occasionally facultative types and the commonly facuhative type is dominant totaling 26 species and accounting for 60 . 4 % of all the species in the reserve 保护区内叶附生苔类植物可以分成3种类型:专性、兼性常见和兼性偶见,其中兼性常见类型种类占有绝对优势,共有26种,占其总种数的60 . 47 % 。 |
| 3. | Lt is probably an obligate parasite in nature and can parasitize various nematodes with a high percentage in some 1ocalities . strain owvtl , isolated from a soybean cyst nematode supperssive soil in minnesota , u . s . a . , has showed high potential in biocontrol of nematode 由于在自然界中对线虫寄生率高、寄生性强、与线虫抑制性土壤有关、自然条件下为专性寄生菌,因而极具生防应用潜力。 |
| 4. | The comparison of adsorbing with non - adsorbing rhizobia showed no remarkable difference in content of total cu in cinnamon soil , but adsorbing rhizobia decreased exc - cu and increased spe - cu and mno - cu markedly in cinnamon soil . this indicated adsorbing rhizobia reduced the mobility of cu in cinnamon soil . the total content of zn are 16 . % 褐土吸附根瘤菌后cu的吸持量没有变化,但是可交换态cu含量显著减少,专性吸附态、氧化锰结合态cu含量显著增加。 |
| 5. | The main results were shown as follows : 1 . compared with the control , the fixation of cu by red soil increased 105 mg / kg by 28 % when the soil adsorbed rhizobia . adsorbing rhizobia by red soil increased readily soluble and exchangeable cu ( exc - cu ) , specially adsorbed and other weakly bound cu ( spe - cu ) , cu bound to mn oxides ( mno - cu ) and cu bound to organic matter ( o . m - cu ) by 22 . 8 - 123 % in the soil 土壤吸附根瘤菌后, 1 ) 、对cu的吸持总量红壤增加了105mg kg ,增加率达28 ,改变了各种形态cu的含量,可交换态、专性吸附态、氧化锰结合态和有机结合态cu的含量显著增加,增加率达23 123 。 |
| 6. | The entomophthoralean fungus , pandora delphacis ( hori ) humber , ( zygomycotina : entomophthorales ) is an insect pathogen specific to homopteran insects such as planthoppers , leafhoppers , and aphids and frequently cause epizootics in insect populations . problems with propagation of inocula at a low cost , but high efficiency , have been a technical obstacle to progress for entomophthoralean study and utilization for a long run 飞虱虫疠霉( pandoradelphacis ( hori ) humber )是同翅目昆虫的专性昆虫病原真菌,分类上属于接合菌亚门( zygomycotina )的虫霉目( entomophthorales ) ,常引发飞虱、叶蝉的流行病,也侵染蚜虫、沫蝉等寄主。 |
| 7. | Inoculating rhizobia inhibited the cu dissolution and desorption in cinnamon soil . the content of total cu increased 73 mg / kg when the cinnamon soil was inoculated with rhizobia . compared with non - inoculating rhizobia , inoculating rhizobia showed 20 . 2 - 53 . 8 % increase of exc - cu , spe - cu , mno - cu and o . m - cu in cinnamon soil 褐土中接种根瘤菌抑制了cu的溶解和解吸,褐土cu的总量增加了73mg kg ,达18 ,可交换态、专性吸附态、氧化锰结合态和有机结合态的cu增加了20 54 。 |
| 8. | Inoculating rhizobia enhanced the dissolution and desorption of zn in cinnamon soil . the dissolution of zn are 10 % higher in cinnamon soil inoculated with rhizobia than non - inoculated and spe - zn , mno - zn and o . m - zn decreased by 9 . 2 - 26 . 0 % in the presence of rhizobia . the comprison of inoculating with non - inoculating rhizobia showed no evident distinction in total zn , but inoculating rhizobia decreased spe - zn and mno - znand increased exc - zn in red soil 接种根瘤菌对褐土中zn的溶解和解吸使固定态zn减少66mg kg ,达10 ,专性吸附态、氧化锰结合态和有机结合态zn减少达9 . 2 26 . 0 ,而红壤zn的总量变化不显著,但是专性吸附态和氧化锰结合态zn含量显著减少,可交换态zn含量显著增加。 |
| 9. | Added rhizobia increased the amount of negative charge and metallo - ion specific adsorbing sites of solid compositions such as mn oxides and organic matter etc . the influences of adsorbing rhizobia by soil on the speciation of heavy metal varied with the metal and the soil and were closely related to the mechanisms of metal fixation by soils 土壤吸附根瘤菌后负电荷量增加,某些组分如氧化锰和有机质等吸附重金属的专性吸附位点有所增加。土壤吸附根瘤菌对土壤中重金属的形态影响随重金属种类和土壤类型而不同,与重金属在土壤中的吸持机制有直接关系,当重金属以沉淀机制为主被土壤吸持时,其形态分布受根瘤菌的影响不显著。 |
