In order to study the effect of the methods of application of phosphatic fertilizer on the yield of crops in dry land crop-rice rotation,pot and field experiments on various soils of different pH value and phosphorus composition were conducted.Results obtain- ed showed that the response in yield of wheat or soybean to superphosphate was much more prominent than that of rice in the acid and neutral paddy soils containing large amount of non-occluded iron phosphates.Furthermore,there was good residual effect of superphosphate on rice when the superphosphate was applied to its proceeding crops (wheat or soybean).Additional application of superphosphate to rice in the soybean-rice rotation gave no increase in its yield,whereas the supplementary supply of phosphatic fertilizer to soybean in the rotation of rice-autumn soybean gave marked increase in yield of this subsequent crop. The improvement of the nutrition status of phosphorus in soil after water-logging,as was revealed by the response in yield of crops to phosphatic fertilizer and by the change of “A” value of soil phosphorus,is practically due to the change of the status of iron phosphates in soil.Non-occluded iron phosphates,through the reduction of ferric ion to ferrous state,are converted into a more available form under water-logged condition.This reaction,however,seems to he reversible.The availability of iron phosphates was de- creasing again when the rice field was once drained off for dry farming. From the results obtained it is concluded that for the acid and neutral paddy soils containing large amount of non-occluded iron phosphates,as in cases prevailing in the red earth region in southern China,it seems to be an appropriable recommendation to apply phosphatic fertilizer to dry land crop and leave its residual effect to meet the need of rice.

盆栽试验和不同水旱输作的田间试验结果表明,在含有大量非闭蓄态磷酸铁化合物的南方酸性和中性土壤中,在同一条件下,磷肥对旱作的肥效远较对水稻显著。在输作中,磷肥的后效亦有两种情况:在旱—水(早大豆—水稻)输作中,残余在土壤中的磷素供应水平与继续施用过磷酸钙的供应水平比较,在水稻产量上几乎完全相等;但是,在水一旱(早稻—晚大豆)输作中,则继续施用过磷酸钙的,在晚大豆产量上又增加24%。磷肥对水稻和旱作的肥效有所差异的原因,主要是由于在渍水还原条件下土壤磷素向有效的方向转化所致,而其实质就是土壤中非闭蓄态的磷酸铁化合物的有效转化。这种转化过程的方向及其对磷肥后效的影响视条件而异。在旱—水输作时,施在旱作上的残余磷肥由于渍水还原条件的影响而向着有效的方向转化;在水—早输作时,则向着难效的方向转化。因此,在水旱交替的输作过程中,土壤磷素向有效的或难效的两个相反方向的转化过程,即土壤中非闭蓄态的磷酸铁化合物的活化和老化过程,可能是不断地反复地进行着的。根据上述的试验结果,对于南方合有大量非闭蓄态的磷酸铁化合物的酸性和中性水稻土的磷肥合理施用问题提出了一些参考意见。

The behaviour of Statically penetrating cone is different from that of the pile due to not only the "Scale effect" but also to the differences between their stress field and of thier constitutive materials.

The behaviour of Statically penetrating cone is different from that of the pile due to not only the "Scale effect" but also to the differences between their stress field and of thier constitutive materials. The current methods of determination of bearing capacity of piles by means of static penetration tests take accounts of the "Scale effect" mainly and other factors are considered insufficiently. In this paper, based on the statistical analysis of large amound of results of test piles a madified method of caleulation of ultimate load of rammed concrete piles by means of static penetration tests is developed, and the correcting functions and relation curves of the point bearing and skin friction between the penetrating cone and the pile is also given, which may be used for various soil deposits. The proposed method has been used in the pile foundation of the Zi Ya river bridge, and is verified tentatively in some other districts. It is shown this method is promising and may be useful for practical engineering.

静力触探工作性状与桩不同,不仅在于“尺寸效应”,还在于两者的应力场和所用材质不同。现有用静力触探计算桩承载力的一些方法主要考虑了“尺寸效应”,而对其他因素考虑不足。本文根据大量试桩结果的统计分析,提出用静力触探估算打入混凝土桩极限荷载的综合修正法,并给出静力触探的端阻、局部侧摩阻和桩的端承、侧摩阻间的修正函数值和关系曲线,可用于不同地层条件。本方法已在子牙河桥桩基工程中试用,并在一些地区进行初步验证效果较好,可供实际工程应用,并继续积累对比资料,以便补充改进。

Based on analysing a large quantity of data obtained from in-situ observation and laboratory experiments, it is explored that the main causes offthe land subsidence in Shanghai are the cyclic variation of the ground water table. The reological properties of the 1st and 2nd compressible strata are discussed. The important contribution of the compression of the aqueou sand stratum to the land subsidence in Shanghai is mentioned. In calculating the values of storage coefficient of various soil strata, the rule of rebound and settlement can be readily evaluated by norma-li zing the observed deformation of different soil strata according to the range of variation of the ground water table. The conception of the ratio between rebound and compression is used to study the characteristice of residual deformation of various soil strata in Shanghai.

本文在总结分析以往大量的野外实测资料和室内试验资料的基础上,阐明了地下水位的升降变化是导致上海地面沉降的主要原因。文中论证了第一、二压缩层的流变性质,并指出含水砂层的变形在上海地面沉降中的主要作用。通过对各土层单位变形量的分析,将各土层的实测变形量根据水位变幅予以规格化,以便判断各土层的回升与沉降情况,文中还运用了“胀缩比”的概念,分析了上海各土层的残余变形特征。
