The transformation of fertilizer-NH_4 in three representative arable soils in Hessia, West Germany (loess, alluvial soil and soil of basaltic origin)have been studied by incubation(no plant)under laboratory conditions. The results showed that the amounts of fertilizers NH_4-N fixed by clay minerals in loess and alluvial soils were up to 40% and 32%, respectively after fertilizer application. In soils of basaltic origin, on the other hand, only about 9% of fertilizers NH_4-N were fixed. It is supposed that...

The transformation of fertilizer-NH_4 in three representative arable soils in Hessia, West Germany (loess, alluvial soil and soil of basaltic origin)have been studied by incubation(no plant)under laboratory conditions. The results showed that the amounts of fertilizers NH_4-N fixed by clay minerals in loess and alluvial soils were up to 40% and 32%, respectively after fertilizer application. In soils of basaltic origin, on the other hand, only about 9% of fertilizers NH_4-N were fixed. It is supposed that the specific adsorbed sites of clay minerals in that soil were mainly occupied by K~+ ions. During the incubation process, the amount of fixed ammoniums increased obviously in early stage (about two weeks) and then declined slowly, but at last increased continuously once again. This suggests that the so-called fixed ammonium in clay minerals is no static fraction in soil. It can convert into available N for plants and exists mainly in the form of NO_3~-. The mechanism that NH_4~+ releases from clay minerals is not yet completely understood. From this experiment it is evident that there is a near relationship between the release of NH_4~+ and nitrification in soil. The content of fixed ammoniums declines obviously with the increasing of NO_3-N content. There is a significant negative correlation between the fixed ammonium and nitrate. The γ value was -0.743 for the loess and -0.578 for the alluvial soil. It may be supposed that the significant correlation also exists among these three different N-forms, fixed NH_4~+, exchangeable NH_4~+ and soluble NO_3-N. In general, there is a negative correlation between the fixed NH_4~+ and NO_3-N, and positive correlation between the fixed NH_4~+ and exchangeable NH_4~+; but a significant negative correlation between exchangeable NH_4~+ and NO_3~-. As to the correlation among these three different N-forms it is necessary to be examined by further experiments.

在室内培养条件下(不生长植物)对西德黑森州三种代表性耕作土壤(黄土、冲积土、玄武岩发育土壤)进行铵态氮的转化研究。表明;在黄土和冲积土中,施肥后肥料铵离子分别有40%和32%被粘土矿物固定。在玄武岩发育土壤中,由于粘土矿物的特殊结合位置主要被钾离子所占据,所以施肥后肥料铵离子仅有很少量约9%被粘土矿物固定。在培养过程中固定态铵离子含量呈上升—下降—上升的趋势,说明这种形态的氮在土壤中不是静止不变的,它可以转化为植物可利用的有效氮,主要是硝态氮。可以作为土壤矿质氮的一种“储备”形态。对减少氮的淋洗损失和保证肥料氮在全生长季有较多供应起重要作用。关于粘土矿物中的铵离子的释放机制目前尚未完全清楚。本试验表明,它与土壤中硝化作用有密切关系。随着固定态铵含量下降,硝态氮含量明显上升,两者呈显著的负相关。在黄土中γ=-0.743,在冲积土中γ=-0.578。此外在固定态铵离子和代换性铵离子,以及可溶性硝态氮之间,彼此亦有密切相关。固定态铵离子和硝态氮之间一般呈负相关,固定态铵离子和代换性铵离子一般呈正相关,而代换性铵离子和硝态氮呈显著的负相关。但尚待进一步的试验加以证实。

Incubation method and pot experiment were used to study the mineralization of green manure under submerged condition. The results showed that the amount of nitrogen mineralized from the green manure added to soil was corelated with the effective cumulative temperature i.e.y=k[(T—15)D]~n in which y is the amount of nitrogen mineralized, D the number of days, T the actual temperature during incubation and k and n constants. The rate and degree of mineralization of the green manure varied with the species...

Incubation method and pot experiment were used to study the mineralization of green manure under submerged condition. The results showed that the amount of nitrogen mineralized from the green manure added to soil was corelated with the effective cumulative temperature i.e.y=k[(T—15)D]~n in which y is the amount of nitrogen mineralized, D the number of days, T the actual temperature during incubation and k and n constants. The rate and degree of mineralization of the green manure varied with the species and growing stages of the green manures. It seemed that the characteristics of the mineralization of green manure were dependent mainly by its chemical composition. A good correlation was found between the percentage of the hot water soluble N of the green manure and the nitrogen mineralized when incubated to 1000 effective cumulative temperature. The amount of green manure added to soil and the soil chemical and physical properties also influenced the rate and degree of decomposition of the green manure. The results of pot experiment showed a good correlation with the incubation method. But the amount of N mineralized from the green manure with the pot experiment was greater than that with the incubation method.

为了明确绿肥氮素在淹水条件下的矿化特征,采用培养试验和盆栽试验两种方法进行研究。结果表明,在20—30℃淹水培养条件下,加入土壤中的绿肥氮矿化率与有效积温(T—15)D的关系,符合y=K[(T一15)D]~n经验公式的规律。绿肥不同品种及不同生育期,其氮素的分解率及分解速率不同。绿肥氮的分解特征,主要由其化学组成所决定,绿肥中热水溶性氮的百分率与培养1000(日·度)有效积温时氮的矿化率之间相关密切。土壤中的绿肥加入量及土壤本身的物理化学性质对绿肥的分解率及分解速率也有影响。盆栽试验结果与培养试验结果相关良好,但绿肥在盆栽条件下的矿化率较培养条件下高。

A leaching experiment of Zn through a soil column and a zinc adsorption study by soil under incubation at varying periods of time were Carried out in the laboratory to reveal the vertical movement and accumulation of Zn in the soil profile. We also analyzed the soils collected from the field experiment, in which zinc sulfate has been continuously applied for several years. The results are summarized as follows:(1)In paddy soils the downward movement of Zn was small. Most of the applied Zn was concentrated on the top soil, with a little in 15~30 cm and the least in 30~40 cm depth.(2)The application of both P and Zn did not decrease the amount of available znin the soil.(3)The application of ZnSO_4 increased not only the level of available Zn in the soil but also the Zn content of rice straw and grain significantly.
