For the study of the influence of oxidation-reduction conditions of thesoil on the growth of rice plant,pot experiments with three paddy soilswere conducted.The used soils included an acid paddy soil derived from quartiary red clay,an acid mountain paddy soil derived from granite anda neutral alluvial paddy soil.It was found that the application of green manure just before plantingin amount equivalent to 1% of the soil led to the retardation of growth ofrice as compared with the control treatment;dry weights of tops of riceplant amounted to only 78%,22% and 45% respectively of the controls forthe three soils.The difference in growth between the two treatments wasmost remarkable in the early period of plant growth.If the green manurehad been decomposed for one month in pot under semi-aerobic conditionsbefore planting,then the unfavorable effect could be noted only in theneutral alluvial paddy soil which contained a relatively larger amount oforganic matter.The improvement of oxidation-reduction conditions of the soil by inter-mittent applications of hydrogen peroxide and keeping the soil moisturecontent at a level of about 50—70% of water-holding capacity instead ofwaterlogging improved plant growth in soils with intensive reductionprocesses,the effect being most conspicuous in the acid mountain paddysoil where the unfavorable effect of green manure was also most remark-able.Measurements of oxidation-reduction potentials of leaves and stalks ofrice showed that the potentials were lowest when grown in pots with greenmanure,and were highest when hydrogen peroxide had been applied intothe soil.There was also a rough correlation between potentials determinedwith platinum electrode and with quinhydrone electrode,thus indicatingthat the redox systems of rice plant when grown under different oxidation-reduction conditions were not the same both expressed as intensity factor(redox potential)or as quantity factor(the change in redox potential ofquinhydrone).For the purpose of explaining the unfavorable effect of intensively re-duced conditions of the soil on the growth of rice plant,it was noted thatthere was a parallelism between the amounts of exchangeable and water-soluble ferrous iron of the soil and the magnitudes of unfavorable effect.Further pot experiment confirmed this supposition,in which the applicationof ferrous sulfate in amount of 50 mg.iron per 100 grams of soil alreadyled to the retardation of growth of rice.Conclusions were made that the unfavorable effect of reduction condi-tions of paddy soils on the growth of rice was due to the excessive amountof reduced materials,in which ferrous iron probably occuppied an out-standing position,and measures leading to the improvement of oxidation-reduction conditions of the soil could overcome this unfavorable effect.

1.土壤处于强烈的还原条件下时,对水稻生长有不良的影响,如果将土壤中的氧化还原条件改善,则对水稻的生长有益。2.土壤中的氧化还原情况,直接影响水稻体中的氧化还原电位,土壤电位低者,水稻中的电位也低。3.土壤中还原性物质的数量与水稻生长情况表现了明显的一致性,可见水稻在强烈还原条件下的生长不良,与还原性物质的过多有关。在还原性物质中,亚铁离子约占一半左右。4.试验结果指明,土壤中过多的亚铁离子,对水稻有毒害作用。

An adsorption-magnetic separation process for oily wastewater treatment was developed. The removal of mineral oil, COD, turbidity, SS and colour by soil, and the removal of mineral oil and COD by bentonite, activated carbon, coal dust and kaolin as adsorbents were studied. The settling characteristics of SS in the effluent from the process and the reuseability of the soil adsorbent were also investigated. When both mineral oil and COD concentrations in the influent were less than 300mg/L, an effluent with mineral...

An adsorption-magnetic separation process for oily wastewater treatment was developed. The removal of mineral oil, COD, turbidity, SS and colour by soil, and the removal of mineral oil and COD by bentonite, activated carbon, coal dust and kaolin as adsorbents were studied. The settling characteristics of SS in the effluent from the process and the reuseability of the soil adsorbent were also investigated. When both mineral oil and COD concentrations in the influent were less than 300mg/L, an effluent with mineral oil less than 2mg/L, COD less than 100mg/L and SS less than lmg/L could be obtained. After treatment under 400°C for 30 minutes, the used soil adsorbent could be regenerated and used again.

This paper was delivered on the effect of applying molybdenum fertiliser in planosol which was lack of molybdenum(The used soil contained molybdenum of 87 ppb). It firstly promoted the development of soy-Leans both upper and under part of ground, increasing the photosynthesis rate and the area of the leaf by 30% or so; also increasing the weight of root nodule and the activity of nitrogeuase from, two to tenfold. secondly, the remarkable increasing effect was shown ,thus increasing the average per-mu soybean output of 16.98 catties(increasing 9.26% of its out put). The way of its infiltration of seeds was not stabilized. Its effect was sometimes high but occasionally not. while the noiybdenum was sprayed on the surface of the leaves in blooming period, it can reach the best result, increasing 10.7-22.2 catties per mu, increasing 11.3-26.0% compared with the collation. No remarkable accumulated effect was found in spite of applying, molybdenum in the exparmental field for four years running.So it is still a better increasing measure at present to practise molybdenum on the cultivation of soybeans.

本文论述了在缺钼的白浆土上施用钼肥的良好效果(供试土壤有效钼含量为87PPb)。它首先促进了大豆地上地下部分的生长发育。使光合生产率和叶面积提高30%左右,使根瘤鲜重和固氮酶活性增加二陪到十倍以上,其次,表现出显著的增产效果,平均每亩增产大豆4.25公斤,增产9.26%。从钼肥施用方法看,浸种效果不稳定,花期叶面喷钼效果较突出,每亩增产10.7—22.2公斤,较对照提高11.3—26.0%,尽管在试验地连续四年喷施钼肥,未发现钼的明显积累效应,故当前栽培大豆施用钼肥仍是一项良好的增产措施。
