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。

The scientific application of an ideal rotation system on paddy fields,has now been considered as a very important problem for ensuring highergrain yields and promoting soil fertility.As the commencing work onrotation researches,authors had selected to study the Rice-Cotton rotationsystem in Yuyao,Chekiang Province.A series of investigations and ex-periments were conducted in the year of 1955,in order to realize thevariations of soil chemical properties and rice growth on those rotatedpaddy fields.The results obtained are summerized as follows:(1)During the period of Cotton rotation in paddy fields,the organiccontents in the soil tend to decrease,while the total exchangeable bases andavailable phosphorus show an apparant increase.By cultivating rice in suchfields,a reversible tendency appears,namely manifesting an increase ofsoil organic matter content and a decrease of both total exchangeable basesand available phosphorus contents.Besides,the formation of more am-monical nitrogen is found in the later case.(2)The Rice-Cotton rotation will assuredly increase the rate of ricegrowth as well as the yields of grains.Comparing with the unrotatedplot,paddy fields so rotated show an average increase of 9% in grainyeilds,as confirmed by field experiments.(3)In those rotated paddy fields,winter crop-green manure(Medicagodenticulata wild)grew vigorously and showed an increase of 70% in yields(based on fresh weight)as compared with unrotated paddy fields.(4)Rice-Cotton rotation may adjust the rate of the alternation of ac-cumulating and decomposing of soil organic matter,which we know willmarkedly promote soil fertility in paddy fields.Therefore,to save the ap-plication of manure and solve the shortage of fertilizers in grain produc-tion,the use of Rice-Cotton rotation system in certain district,is ofparamount importance at present time.

(1)稻田轮种棉花期间,土壤有机质含量有减低的趋势,但土壤代换性盐基总量及速效磷的合量均增高。轮种水稻期间,土壤有机质又有增加的趋向,而代换性盐基总量及速效磷则渐次减低。此外,土壤中铵态氮则有增多的趋势。(2)稻棉轮种能增强水稻的生长势,提高水稻的产量。根据对比试验及统计资料,一般比连种区增产9%左右。(3)稻田轮种棉花后,冬作绿肥生长良好, 鲜草产量比一般连种稻田增加70%以上。(4)在保证增产的前提下,轮种区的水稻基肥用量,一般可比连作稻区节省40%左右,而轮种区的绿肥产量又能增加,因此可自轮种田内割出60%的绿肥鲜草,作为其他稻田的基肥,而达到全面增产的目的,这在目前肥料普遍不足的情况下有其重要意义。

1.水稻根部的氧化还原电位较根外部者为高。根愈密集,电位也愈高。小麦根部的电位则较根外者为低。水稻根系对土壤氧化还原电位的影响,随其生理情况而不同。2.在氧化性较强的土壤中生长的萵苣体内的电位较高,在还原性较强的土壤中生长者,电位也较低。3.在土壤的氧化还原电位低时,萵苣的生长受到抑制,而在本试验的条件下,水稻仍能生长良好。4.叙述了一种甘汞电极的制作方法,用这种电极,可以很方便地作为直接用白金电极测定植物体中氧化还原电位时的对照电极。
