Field experiment and Laboratory study were made for the comparisionof transformation of nitrogen and the yield of rice in the paddy soil ploughedunder dry and water-logged conditions.The drying of the soil after ploughing did not effect the ammonia-nitrogen content of the soil or the yield of rice under field conditions.After water-logging,the amount of nitrate-nitrogen decreased rapidly,and it disappeared within a few days as the soil intensely reduced.The effect of drying of different typies of paddy soil on the ammonia-nitrogen content were studied in the Laboratory.These results showedthat there was a Large increase of ammonia-nitrogen content in the soilunder water-logged conditions after drying as compared with the non-airdried samples.The magnitude of the increase in ammonia-nitrogen contentwas influenced by the characteristics of the paddy soil,such as the redoxpotential and the content of organic matter,especially the degree of drying.It is considered that the drying of paddy soils under cultivation is apowerful means in increasing the soil fertility and the yield of rice,especially for the subhydrogenic paddy soils,but in case of soils with highredox potential and low content of easily decomposable organic nitrogeneouscompounds,such as those soils derived from loess-like material,on whichthis field experiment was conducted,the drying of the soil did not increasethe amount of ammonia-nitrogen of the soil or the yield of rice.

1.在南京低丘地区,发育于黄土性母质上的轻度潴育性水稻土,在水旱连作的栽培制度下,本田耕地,通过干耕晒垡过程,并无效果。2.本文对不同类型水稻土干燥后的铵态氮动态,进行了测定和讨论,认为对于还原性强烈而腐殖质较多的水稻田,干耕晒垡是发挥水田潜在地力的有效措施,且只有在土壤充分干燥情况下,才能加速土壤有机质的矿化过程,但是,对于一般腐殖质含量较低,而无显著沼泽化迹象的轻度潴育性水稻土,由于土壤氧化势较高,土壤本身对促进有机物的分解具有良好条件,在田间情况下,对于耕作上某一短期的土壤干燥过程,不易产生较为明显的效果是可能的。3.对于水稻生长期间,土壤中NH_4~+及NO_3~-的动能进行了初步分析和讨论,初步指出,在长江下游地区,水田肥力的发挥,可能在很大程度上有赖于对土壤矿化过程的促进。

For the purpose of comparing the relative effect of various farm manures,field experimentswere carried out for four years at Nanking on a paddy soil;containing organic matter 1.5%,deri-ved from yellowish brown earth.The adsorption of nitrogen by one harvest of rice plant of the medium ripening variety was22—27% for rape-seed cake,17% for green manure,15% for water-logged compost,13% forstable manure,and 4.6—6% for pond mud.For rice of the early ripening variety,the percentageadsorption of nitrogen was 30%,20%,7.3% and 5.7% for the green manure,water-loggedcompost,mixed stable manure of cattle and swine,and grass compost respectively.On the basis of relative effect of various manures on the yield of rice,it was calculated that1 kg N of stable manure was equivalent to 0.45 kg N of rape-seed cake,0.55 kg N of greenmanure,0.7 kg N of water-logged compost,and 2.1—2.5 kg N of pond mud.For rice of theearly ripening variety,1 kg N of stable manure was equivalent to 0.38 kg N of gree manure,0.49 kg N of water-logged compost,and 1.19 kg N of grass compost.The liberation of nitrogen from manures proceeded most rapidly for the green manure,rape-seed cake entering the second and then water-logged compost.The liberation of nitrogen fromthe pond mud was so slow that it could hardly be distinguished from the controll treatment.Attention must pay to use nitrogen fertilizers as top-dressing when large amount of green manurehad be applied in order to prevent the lodging of rice plant,and on the contrary the applicationof top-dressing was essential when pond mud was used as the basic dressings.

本试验(自1956—1959年)在南京黄褐色母质发育的水稻土(有机质1.5%,全N0.086%,速效P_2O_5 0.008%,速效K_2O 0.0178%)上进行。1.各农肥的肥效如下:(1)氮素肥效折合率约为:中稻:堆(?)肥1斤N(?)菜饼0.45斤N(?)绿肥0.55斤N(?)草塘泥0.7斤N(?)塘泥2.1—2.5斤N。早稻:猪牛(?)肥1斤N(?)绿肥0.38斤N(?)草塘泥0.49斤N(?)青草堆肥1.15斤N。(2)对水稻的氮素吸收利用率约为:中稻:菜饼22—27%,草塘泥15%,绿肥17%,堆(?)肥13%,塘泥4.6—6%。早稻:绿肥30%,草塘泥20%,猪牛(?)肥7.25%,青草堆肥5.7%。2.各农肥在水田中自6月中旬至9月上旬,NH_4-N 的释放量以绿肥最快最大,菜饼的分解速率仅次于绿肥,但在施肥一个半月后释放量达到最高峯。草塘泥兼有迟速效特性,释放速率及释放量都比较平稳,不象绿肥那样猛发,又比堆(?)肥速效成份高,比河泥养分释放快。堆(?)肥释放情况介于草塘泥与河泥之间,后期分解量较高。河泥释放量最差,有时几和对照相近。此外,土壤分析结果指出:在种中熟籼稻的土壤中NH_4-N ...

本试验(自1956—1959年)在南京黄褐色母质发育的水稻土(有机质1.5%,全N0.086%,速效P_2O_5 0.008%,速效K_2O 0.0178%)上进行。1.各农肥的肥效如下:(1)氮素肥效折合率约为:中稻:堆(?)肥1斤N(?)菜饼0.45斤N(?)绿肥0.55斤N(?)草塘泥0.7斤N(?)塘泥2.1—2.5斤N。早稻:猪牛(?)肥1斤N(?)绿肥0.38斤N(?)草塘泥0.49斤N(?)青草堆肥1.15斤N。(2)对水稻的氮素吸收利用率约为:中稻:菜饼22—27%,草塘泥15%,绿肥17%,堆(?)肥13%,塘泥4.6—6%。早稻:绿肥30%,草塘泥20%,猪牛(?)肥7.25%,青草堆肥5.7%。2.各农肥在水田中自6月中旬至9月上旬,NH_4-N 的释放量以绿肥最快最大,菜饼的分解速率仅次于绿肥,但在施肥一个半月后释放量达到最高峯。草塘泥兼有迟速效特性,释放速率及释放量都比较平稳,不象绿肥那样猛发,又比堆(?)肥速效成份高,比河泥养分释放快。堆(?)肥释放情况介于草塘泥与河泥之间,后期分解量较高。河泥释放量最差,有时几和对照相近。此外,土壤分析结果指出:在种中熟籼稻的土壤中NH_4-N 在10微克/克土(ppm)以下似难被利用(图1)。3.就植株氮素吸收利用及生长情况可看出:施用绿肥对中稻的营养生长有特别促进作用。如施用量稍多,就会引起先期猛发,徒长茎叶,增加草谷比例,产量并不能提高,因此施绿肥时,配合速效氮肥做面肥或施追肥时应特别注意,在绿肥用量较高时,再用速效氮肥往往有害无益。如直接施用绿肥,则施用量不宜过多,耕翻时也要适当提早,速效肥要看苗施用。草塘泥性平稳,用做基肥时,配合少量化学氮肥做面肥及穗肥均可进一步提高产量。堆(?)肥与河泥性质慢,不论施用于中稻或早稻,均必须增施速效肥料,不然肥效很低。早稻生长初期气温低,农肥养分释放慢,同时早稻生长期短,插秧后20天即进入幼穗分化期,因此分解较快的绿肥,及含速效氮较多的草塘泥用做早稻基肥,效果更为显著。所有农肥增施了速效氮肥做面肥及追肥都有良好增产效果,其中分解愈慢的农肥效果愈大。例如绿肥及草塘泥增施速效氮肥后产量增加48.3%及43.2%,N 素吸收利用率增加1倍及8成,而青草堆肥配合速效氮肥时,产量增加85%,N 素吸收利用率提高近四倍(表13)。4.各农肥单独施用做早稻基肥时,植株每日氮素吸收量皆以抽穗期为最多,若增施速效N 肥后,则每日氮素吸收量最多时期均由抽穗期提前至幼穗分化期,同时产量也显著提高(表5)。

For the study of the micro-regional properties of soils,microelectrodes are useful forthe measurements of redox potential,pH value and electric conductance.When the buffered solutions were saturated with quinhydrone,the values of theoretical potentials canbe obtained by the micro pt electrode with a diameter of 0.5 mm and length of 0.2 mm.If redox potentials of soils are ranged from 80 to 450 mv,2—5 mv lower than the ordinary large electrode were found as measured by the microelectrode.For the measure-ment of...

For the study of the micro-regional properties of soils,microelectrodes are useful forthe measurements of redox potential,pH value and electric conductance.When the buffered solutions were saturated with quinhydrone,the values of theoretical potentials canbe obtained by the micro pt electrode with a diameter of 0.5 mm and length of 0.2 mm.If redox potentials of soils are ranged from 80 to 450 mv,2—5 mv lower than the ordinary large electrode were found as measured by the microelectrode.For the measure-ment of pH value of air-dried soils,the difference between the micro quinhydrone electrode and the glass electrode was insignificant.In water-logged soils with a redoxpotential below 350 mv,however,the experimental error may be 0.3—0.6 pH unit.In the measurement of electric conductance with microelectrodes,the apparent cellconstants increased with increasing concentration of KCl solution even after platinizationof the electrodes,if the length of the Pt or Ni wire in the cells is less than 1 mm and thtance between these two wires less than 1 mm.In the experiments,the reproducibility of the measured apparent cell constants at different intervals was favorable andcalibration curve can be used for correction.The results of application of the microelectrodes are summarized as follows:(1)For soil clods containing large amount of easily decomposable organic matter,the redox potential in the central part of the soil clod may be 220 mv lower than thesu(?)face.The electric conductance at the surface was 10—20% higher than the centralpart.(2)In two different soils studied,the ionic diffusion of granulated superphosphatewithin a certain distance corresponds to the Fick's log C=log A-Kx~2 relation.(3)The root system of buckwheat decreased the pH value of soils in the rhizosphere from 6.22 to 5.10 and increased the specific conductance by about 52 per cent ascompared with the bulk soil.The specific conductance of soils in the rhizosphere of ricewas 37 per cent lower than the bulk.The root of all the tested plants exc ricelowered the redox potential in the soils of rhizosphere.(4)For rice plant collected from five plots of different levels of soil fertility,theratio of electric conductance between the soil and the rice roots was found to be constant,as 0.31±0.02 in average.The electric conductance in the functional leaves also increased with the increase of conductance of the soil.

为了研究土壤电化学性质的微域变化,应用微电极,测定了氧化还原电位、pH 和电导。结果表明,在含氧化还原体系的标准液中,测得的电位值与理论值相符,在土壤中,数值可较大电极低2—5毫伏。在应用微氢醌电极法测定土壤的pH 时,对干土所得的结果与玻璃电极数值一致;对于还原性土壤,不能够应用。在应用微电极测定电导时,对于长1毫米,极间距离1.1毫米的电极,在不同浓度溶液中可得一致的电导池常数,对于更小的电极,电导池常数随溶液电阻的减小而增大。在土壤中长期磨擦时,可导致电导池常数的稍许增加。应用了标准线的方法校正了这些误差。土块表面的氧化还原电位,较其内部为高。表面的电导也可以较内部高10—20%。颗粒磷肥在土壤中的离子扩散,在一定距离范围内符合log C=log A-kx~2的Fick扩散定律。荞麦使根际土壤的pH 降低,电导升高,氧化还原电位升高;水稻使根际土壤的电位升高,pH 降低,电导降低;小麦和大豆使根际土壤的电位降低。水稻根系的电导,与土壤中者保持一基本固定的比例。
