  an value
The fertilizer N equivalent for the cropping system; "AN" value and "A" value (analogous to AN), but in fertilizer 15N units, soil biomass, and C and N mineralization were monitored.
      
Effect of nitrogen application on the AN value of soil
      
The results showed that the Rottenhaus soil had a higher AN value than the Seibersdorf soil, suggesting that the former was more fertile than the latter.
      
Thus, the AN value as determined by the two test crops differed significantly for the same soil when the rate of N application was greater than 20 kg/ha.
      
The dependence of the AN value on the level of N application and the species of crop seriously compromises the suitability of this method for determining plant-associated N2 fixation.

The molecular weights of nine fractionated samples of butadiene-styrene copolymer were determined osmometrically in toluene at 25°. Experimental technique for the use of osmometer and the swelling of cellophane membrane in 5—30 pct NaOH solutions have been described. The change of permeability during repeated use of the membrane and its possible deformation during a determination were discussed.π/C vs C plots for the system studied are non-linear, while the experimental data permitted linear extrapolation on (π/C)~(1/2) vs C plots to give M_n and A_2 values. The ratio A_2M_n/[η] was found to be a constant, independent of M_n.The[η]-M relation obtained is [η]=1.25×10~(-4)M~(0.78)dl/g in toluene at 30°. The somewhat higher value of a obtained is explained by the fact that previous workers applied linear extrapolation on π/C vs C plots and the possible branching of the samples used was neglected.

Die Hoch-und Tief-Umwandlungstemperatur des Cristobalits hngt von den Bedingungen seiner Entstehung und schwankt in einem Bereieh yon 180° bis 270℃. Um sich die Schwankungen der Umwandlungstemperatur von Cristbalit und seine Ursaehe zu erklren, haben wir den Einfluss der Faktoren, namentlich den Korngrssen der Rohstoffe, Entstehungstemperatur, Rohstoffsorten und den Mineralisatoren, auf die Umwandlungstemperatur untersucht. Folgende Regelmssigkeiten werden erhalten:1. Die Umwandlungstemperatur hngt von den Korngrssen des auf Entstehungstemperatur unter 1600℃ gebildeten Cristobalits ab. Je feiner die Korngrse dee Bildungsstoffes, um so hher liegt die Umwandlungstemperatur. Gleichfulls die Korngrsse im Bereich von 67.5 his 90μ zeigt sich besonders heftig.2. Die Umwandlungstemperatur erht sich recht gleichmssig mit seiner Entstehungstemperatur nach der Gleichung: t_i=a+bt_f (dabei ist t_i—Umwandlungstemperatur; t_f—Entstehungstemperatur). Es wrid experimentell gefunden, dass die werte a,b abhngig von Rohstoffsorten sind. Fr armorphe Rohstoffe ist b grsser und a kleiner, whrend f kristallische Rohstoffe, ist es umgekehrt.3. Mit zunehmenden Kristallisationsgrad der Rohstoffe wird die Umwandlung zu hheren Temperaturen verschoben, nach der Ordnung: Kieselquarz>Kristalline quarzite>Hornstein>Amorphe Kieselsure.4. Die umwandelnde Kraft yon Mineralisatoren auf die Quarzumwandlung ist strker, je hher die Umwandlungstemperaturen liegen. Es erhht sich folgendermassen: Li_2CO_3>Na_2CO_3>Na_2WO_4>FeO>CaO.

本文探討方石英高低温型轉变温度的变化規律及其原因。就形成方石英的原料颗粒大小、燒成温度、原料类型和矿化剂种类等因素对轉变温度的影响进行研究。結果表明: 1.原料的顆粒大小对1600°以下温度形成的方石英轉变温度有影响,顆粒愈小,轉变温度愈向高温移动,这种傾向对67.5—90μ范圍内的顆粒特別明显。 2.燒成温度以直綫关系影响轉变温度向高温移动,以方程式t_i=a+bt_f(t_i—轉变温度;t_f—燒成温度)表示此关系时,a,b的值依原料类型不同,非晶質原料的—a值小,b值大;結晶質則相反。 3.原料类型依結晶度的高低影响轉变温度移动,結晶度愈高的原料形成的方石英轉变温度愈高,即按:脉石英>石英岩>燧石岩>非晶質硅酸的次序温度升高。 4.矿化剂作用力的强弱对方石英的高低温型轉变温度亦有影响,矿化作用愈强的矿化剂愈影响所形成的方石英轉变温度向高温移动,其次序为:Li_2CO_3>Na_2CO_3>FeO>CaO。

Eighteen samples of paddy soils developed on red earth,alluvial and lacustrine de-posits and Hsiasu loam(a heavily leached loess deposit)were collected from Kwantung,Kwansi,Kiangsi and Kiangsu provinces.They possess pH value from 5.4 to 8.0 andare of different fertility.Fractionations of soil mineral phosphate were conducted accord-ing to Chang and Jackson's scheme.Analytical results revealed that iron phosphate,mostof which are coated with ferric oxide,predominate in paddy soils of acid and neutralreaction.Seven acid and neutral paddy soils were subjected to pot culture experiment.The“A” values for available phosphorus according to Fried were determined at differentgrowing stage of rice.Significant correlations between the content of iron phosphates tothe “A” values were found at all stages of growth of rice after the beginning of tillering,showing γ values 0.95 with 1% level at maturity.Correlations between the contents ofaluminium phosphate and calcium phosphate to the “A” values are rather insignificant,but it does not imply the inavailability of soil phosphorus in this form.A series of supplementary pot experiment were conducted with synthetic strengite(FePO_4·2H_2O),prepared from labelled phosphate.The effective uptake of labelledphosphate by rice plant verified the availability of phosphate ions originated fromstrengite.Solubility curve of strengite,after being transformed under anaerobic condi-tions,shows close coincidence with that of from amorphorus ferric phosphate(FePO_4·xH_2O).It is believed that strengite is firstly changed to more soluble ferrousphosphate under water-logged condition,and the phosphate ions is then reprecipitatedby active sesquioxide(predominantly iron oxide)to form amorphorus ferric phosphate,which has been proved a proper source of available phosphorus to rice plant.Littlechanges in solubility curve even occur when strengite was incubated with soils in anaerobic condition.This gives further evidence of the present conclusion.

研究了我国南方18个不同类型水稻土标本的无机磷的形态。结果表明,非闭蓄态的磷酸盐,包括磷酸铝、磷酸铁和磷酸钙三种形态,一般占土壤无机磷总量的30—60%,其中磷酸铁一极占非闭蓄态总量的50—80%。土壤无机磷中另外的40—70%主要是被氧化铁胶膜包蔽的磷酸铁和磷酸铝。应用同位素P~(32)示踪法进行的水稻盆栽试验表明:在水稻不同生育期,土壤有效磷量“A”值与水稻土中非闭蓄态的磷酸铁化合物具有极显著的相关性(成熟期的r=0.95)。用P~(32)人工合成的两种不同晶形的磷酸铁进行了水稻盆栽试验;进一步指出:在水稻土的条件下,晶形的粉红磷铁矿对水稻具有良好的磷素供应能力。这些结果说明,水稻土中非闭蓄态的磷酸铁化合物,即使是以比较稳定的结晶状态存在,但却有可能作为水稻磷素营养的重要给源。室内试验表明,粉红磷铁矿所以对水稻磷素营养具有良好供应能力,以及酸性和中性水稻土中的非闭蓄态磷酸铁化合物,所以能作为水稻磷素营养的重要给源,主要是受渍水还原过程的影响,这一过程,使原来晶形的磷酸铁化合物转化为无定形的状态。
