    To three cultural media composed of montmorillonitic,kaolinitic and illitic type of clay minerals,treatments were made for varying degrees of saturation of exchange- able calcium,magnesium and potassium with constant base exchange capacity.The effect of complementary ions on the availability of exchangeable Cations was judged from the yields as well as their chemical composition of the plants growing on them. The results are summarized as follows. 1.No difference was noticeable among different types of clay minerals with respect to the effect of the nature of complementary ions on the availability of the exchangeable cations. 2.As a complementary ion,the higher the degree of saturation of calcium,the lower the availability of the exchangeable magnesium.Similarly,magnesium as a complementary ion has also the same effect on the availability of exchangeable mag- nesium as calcium does on magnesium. 3.The availability of exchangeable potassium increases with the increase of the degree of saturation of calcium functioning as a complementary ion to the exchangeable potassium.But,to the contrary,potassium as a complementary ion affects the availa- bility of exchangeable calcium in the reverse direction.Situation is just about the same between the mutual effect of the exchangeable magnesium and potassium. 4.Results from illitic series of the cultural media showed that with respect to the availability of exchangeable potassium,calcium as a complementary ion is preferable to magnesium,and with respect to the availability of exchangeable calcium,potassium as a complementary ion is superior to magnesium. 5.From the results,it seems that under the conditions of the same base exchange capacity and the same amount of exchangeable potassium content,calcium clay will afford more available potassium as compared with hydrogen clay.This gives a new explanation of the disadvantages of the acid soil and adds to the support for liming an acid soil.According to the author's opinion,the reported deficiency of available calcium supply in some of the alkali soils,in which the total calcium content was known to be sufficient,may be explained from the standpoint of the unfavorable effect of the complementary ion (Na) on calcium. 6.Suggestions are made that rational application of mineral fertilizers should be made according to the status of the exchangeable cations of the soil.It is rather the degree of saturation of the exchangeable cations and the nature and proportion of the complementary ions than the absolute amount of the nutrients as such or the total percentage content of them on the soil weight basis,that will count in order to afford sufficient quantities of available cations for the nutrition of the plants.The unit of fertilization rate (dosage) is,indeed,a relative concept (relative to the base exchange capacity) and not an absolute weight or an ordinary percentage concept. 7.Attempts were made to explain the effect of different complementary ions on the availability of exchangeable cations by the concept of exchange bonding energy of the various cations.The explanation is serviceable in limited cases.More work is yet to be done before a satisfactory theory can be found to fully explain the com- plementary ion effect. 8.It is reasonable to doubt whether some of the antagonistic phenomena between cations observed on the plants growing in soil reported by physiologists are actually physiological problems at all.Might not these be just matters of complementary ion effects in the soil?

    The present paper deals with the influence of the intensity and its persistence of nitrogen supply to the formation and development of the organs of rice plant and also with the resulting physiological feature of these influences. Pot culture experiments with paddy soils were conducted in open field. Organic manure and ammonium sulphate were applied at different stages of growth, i.e. tillering, internode elongating and panicle differentiating stage. The results are summarized as follows:1. Experiments revealed that various organs of rice plant gave different responses to the status of nitrogen supply, and to the same organs, their responses of nitrogen varies at different stages of growth. At the tillering stage, a strongly intensified and less persistent supply of nitrogen, as in the case of ammonium sulphate, promoted the assimilation of dry matter in leaf blade, and consequently enlarged the leaf areas. Such an effect on the leaf blade, however, terminated after the internode elongating stage, and more accumulation of dry matter was found in the stems. Top dressing of manures, pertinently after the internode elongating stage, gave a moderate but persistent supply of nitrogen at that time and resulted the formation of large and healthy ears. Under theexperimental condition, such treatments have been proved favourable to the growth and yield of rice.2. The influence on the growth of the organs, as resulted by changing the status of nitrogen supply, is mainly induced by the rate of accumulation and translocation of nitrogen in plant. A strongly intensified, but less persistent, nitrogen supply accelerates the rate of translocation of nitrogenous materials, while a less intensified but rather persistent supply of nitrogen retains more nitrogenous materials in leaf blade.3. It is evidently that the demand of nitrogen supplying status of rice plant differs at different growing stages. Under the experimental condition, high yields of rice crops were attained by a slower but persistent rate of nitrogen suppy in the tillering stage; a faster but less persistent rate in the internode elongating stage and also a moderate but persistent rate in the penicle differentiating stage. Since property of soil nitrogen varies in different soil type, the regulation of nitrogen supplying status by fertilization should be different in cach cases.

    Ammonium bicarbonate, still being one of the main nitrogen fertilizers at present time in China, is easily volatilizable in soils. Various field experiments as well as practices have repeatedly shown that, if prilled and applied beneath the soil surface about 6 cm, its effect on the growth of crops will be markedly increased. In order to get some idea about the mechanism involved in its beneficial effect, the present study was undertakers. Experiments were carried out in pots under greenhouse conditions as well as in the paddy field using N~(15)-tracer technique. The following is a summary of the results.1. When ammonium bicarbonate was prilled and deeply applied to the soil, much more total available nitrogen as well as ammonium nitrogen alone were found in the soil throughout the growing season, as compared with the surface-application of the powdery form. Neither surface application incorporation of the powdery fertilizer into surface soil have hardly matched with it in these respects.2. As compared with the powdery fertilizer applied in the conventional way, the deeply applied ammonium bicarbonate prills showed its fertilizing effect quite slower but rather steadier and hence lasting longer. The improved nitrogen supplying status of the soil resulted in a greater amount of nitrogen assimilation and dry matter production with an apparent strengthening of the over-all growth vigor of the rice plants.3. With high rates of fertilization (corresponding to 130 catties/mow), and under dense planting conditions, the nitrogen recovery of the deeply applied ammonium bicarbonate prills as calculated from the amounts of labelled nitrogen (N~(15)) found in the adjacent rice plants around the site of application, amounts to 75.5±3.4%, which constitutes more than half of the total nitrogen in the rice plants (i. e. 54.6±1.8% of the total nitrogen, to be exact). On the other hand, the nitrogen recovery of the powdery fertilizer applied in the conventional manner is generally much lower as has been widely reported. The difference in their recovery perentages may be ascribed mainly to the difference in their volatilization losses of ammoniacal nitrogen. Besides, the differences in their amounts of ammonium ion fixed by the soil, immobilization of available nitrogen by rhizosphere microorganisms, as well as the accessibility and availability of the fertilizer nitrogen to the plant roots may also bear some effects on their nitrogen recovery rates. Just to what extent each of these factors contributes to the total effects is yet to be illucidated by further experimentation.4. Under field conditions with a planting space of 10×10 cm. between hills, the nitrogen released for absorption from ammonium bicarbonate applied deeply in the center of space can only be accessible to the four rice plants around the site of application. This amounts to over 90% of the total nitrogen released for absorption from the fertilizer as shown by the N~(15)-tracer experiment.

    通过盆栽试验和田间N~(15)同位素试验,研究了碳铵粒肥在水田深施的氮素供应状况。结果表明,在碳铵粒肥深施情况下,土壤氮素总供应量在整个水稻生长期中,土壤NH_4-N量和速效氮量在施肥后持续30天的时间内,均显著高于粉肥表施和粉肥混施。粒肥深施对水稻的供氮特点是缓、稳、长,这反映在不同时间水稻的氮素积累量、干物质积累量和长势的变化上。粒肥深施明显地增进了水稻对肥料氮素的吸收。通过N~(15)的田间示踪试验表明,即使在重肥条件下,水稻对深施碳铵粒肥的氮素利用率也高达75.5±1.8%,水稻总积累氮量中有54.6±3.4%是来自于深施碳铵粒肥的。深施碳铵粒肥在田间的有效供肥范围为施肥点四周的第一圈稻株,约占碳铵总供肥量的90%以上,而第三圈已完全无效。
