This investigation was undertaken to attain by means of pot cultures and chemical analyses a better understanding of the significance of the degree of base saturation in relation to the growth and mineral composition of certain crops. Two relatively pure mineral colloids, bentonite and kaolin, and a lucastrine orchard soil containing illitic type of clay minerals were used for the studies. Bentonite and kaolin were first electrodialyzed and then mixed with different amounts of pure quartz sand to give different levels of base exchange capacity. Treatments were made to all three cultural media for varying degrees of base saturation with constant ratio between exchangeable bases. Oats and rye were grown in succession in montmorillonitic and kaolinitic media, while peach, soybean, proso, tomato and oats were grown in the illitic soil. Dry weights and contents of certain mineral constituents of oats, rye and tomato were determined. Yield data from the montmorillonitic media showed nearly linear relationship between the degree of base saturation and the growth of the plants. In the kaolinitic media the increase of yield was only noticeable from the first increment of bases, effects above 40% total base saturation being insignificant. The results from illitic soil were intermediate between those mentioned above, i.e., the highest yield of tomato was obtained at the 75% saturation level. The yield data further indicate that the growth of plants was more closely related to the degree of base saturation than to the total supply of exchangeable bases. With the same amounts of bases and at the levels below 60% base saturation, the yields of rye in the kaolinitic colloid were higher than in the montmorillonitic colloid. In the montmorillonitic media, the increase of Ca uptake by the plants from the first increment of Ca was pronounced with only little effects above 30% Ca saturation (or 40% level of total base saturation). The K content of the plants was increased appreciably at only the higher levels of base saturation, while significant increases of the Mg content of the plants occured at lower levels (i.e. below 60% base saturation level). In the kaolinitic media, no appreciable change of Ca and Mg contents of the plants was noticed. This is an interesting contrast to the results obtained with the montmorillonitic media. However, there were definite increases in K content of plants with increasing increments of K at the lower levels of saturation. The higher contents of Ca and Mg in the plants were found in kaolinitic media rather than in the montmorillonitic media provided that the total base saturation level was under 60% of the exchange capacity. On the other hand, the K content of the plants from montmorillonitic media was invariably higher than from kaolinitic media. In the illitic soil, the most marked increase of Ca content in plants occured when the degree of base saturation increased from the 50% to the 75% level. Beyond that point, no appreciable increase was noticed. As the degree of base saturation of illitic soil increased, the K and Mg percentages in plants increased also. Among the conclusions obtained from the experiments, the following are of outstanding significance: 1. Exchangeable cations are not equally available. With the equal supply of total exchangeable cations, their availability varies with the degree of base saturation. Within a certain range, the higher the degree of base saturation, the greater the availability of the exchangeable cation. This affords a theoretical explanation of the advantage of localized application of fertilizers. 2. The availability of exchangeable cations varies with the nature of clay minerals. With the given amount of exchangeable cations and the same degree of base saturation, the individual exchangeable cation held by the clay mineral differs in availability according to the following order: For Ca" and K', kaolinite>montmorillonite>kaolinite. This gives the reason why a montmorillonitic soil should be fertilized with respect to the Ca and K to higher levels than a kaolinitic soil. 3. In order to afford sufficient amount of active cations for the growth of plants, higher degree of ionic saturation is required for Ca" than is for Mg", which in turn should be higher than for K'. The study also discusses, from the theoretical point of view, some of the factors involved in determining the availability of exchangeable bases.

本研究之主要目的在于寻求不同粘粒矿物所吸附的代換性陽离子对植物生長及其矿質营养成分的影响。通过这一試驗,希望了解影响代换性陽离子的若干重要因子,从而提供关于施肥原則及技术的若干理論。试验分温室栽培及植株化学分析兩部份。栽培所用植物包括燕麦、黑麦、小米、大豆、番茄、桃树等数种,培养基根据所合粘番矿物不同,分微晶高陵土系,高陵土系及水化云母系三大类。培养基的鹽基代換率、鹽基飽和度,以及各代换性鹽基間的互相比例,均加以控制。另以砂培处理为对照,試驗的主要結果可以綜結如下: 1.在微晶高陵土系的栽培試驗里,植物的生長概和鹽基飽和度成直线相关,但高陵土系及水化云母系的栽培試驗結果并不完全如此。在这些培养基理,植物的生長,虽然也因鹽基飽和度的增加而改善,但其改善的趋势停止于一定的鹽基飽和度水平上。例如,在本試驗里,对黑麦和燕麦言,当高陵土系培养基的鹽基飽和度达到40%时,或对番茄言, 当水化云母系培养基的鹽基飽和度达到75%时,植物的生長都不再因鹽基飽和度的增加而改善了,这說明就植物的矿質营养言,鹽基飽和度具有特殊重要的意义。一般說来,鹽基飽和度愈大,代换性鹽基的有效度也愈大。 2.作为影响植物矿質营养的土埌肥力因素,鹽...

本研究之主要目的在于寻求不同粘粒矿物所吸附的代換性陽离子对植物生長及其矿質营养成分的影响。通过这一試驗,希望了解影响代换性陽离子的若干重要因子,从而提供关于施肥原則及技术的若干理論。试验分温室栽培及植株化学分析兩部份。栽培所用植物包括燕麦、黑麦、小米、大豆、番茄、桃树等数种,培养基根据所合粘番矿物不同,分微晶高陵土系,高陵土系及水化云母系三大类。培养基的鹽基代換率、鹽基飽和度,以及各代换性鹽基間的互相比例,均加以控制。另以砂培处理为对照,試驗的主要結果可以綜結如下: 1.在微晶高陵土系的栽培試驗里,植物的生長概和鹽基飽和度成直线相关,但高陵土系及水化云母系的栽培試驗結果并不完全如此。在这些培养基理,植物的生長,虽然也因鹽基飽和度的增加而改善,但其改善的趋势停止于一定的鹽基飽和度水平上。例如,在本試驗里,对黑麦和燕麦言,当高陵土系培养基的鹽基飽和度达到40%时,或对番茄言, 当水化云母系培养基的鹽基飽和度达到75%时,植物的生長都不再因鹽基飽和度的增加而改善了,这說明就植物的矿質营养言,鹽基飽和度具有特殊重要的意义。一般說来,鹽基飽和度愈大,代换性鹽基的有效度也愈大。 2.作为影响植物矿質营养的土埌肥力因素,鹽基飽和度的重要性一般超过鹽基代換率。試驗的結果表明:鹽基代換率不等,而鹽基飽和度相等的同一發生学来源的土埌,其植物生長狀况一般相等或相差不远。这說明代換性鹽基的絕对数量不足以指示作物生長的优劣。不仅如此,試驗的結果也啟示出含代換性陽离子絕对数量相等的兩种同源土埌,就对植物的矿質营养言,并不意味着具有相等的供应該有效性陽离子的能力。由于它們間質地上的可能差異,——質地輕者鹽基代换率小,質地粘重者,鹽基代換率大,——因之其鹽基飽和度就不相等。飽和度大者,鹽基的有效度就高。 3.栽培試驗及室內化学分析的結果都表明在总鹽基飽和度为60%以下的土埌中(Ca:Mg:K=15:3:2),高陵土类粘粒矿物上的代换性Ca~(++)及Mg~(++)的有效度均高于微晶高陵土,而K~+則相反。 4.植物矿質成分的化学分析結果表明:各营养离子的鹽基飽和度在一定范圍内的变化,可以显著地影响它进入植物体內的量。例如,当微晶高陵土系培养基的鈣离子飽和度在30%以下的范圍內作增减的变动时,都能明显地反映在其所生長的植物体內的含鈣量上。植物体內的鉀离子,則能反映飽和度自4%至6%的范圍內的变化。鎂的情况大体近似于鉀,只是其变化范圍更小一些。这說明同一种植物为了滿足其自身的营养需要,对于同一种粘粒矿物上所吸附的不同离子,有不同的飽和度的要求。鈣最大,(对黑麦,燕麦而言約30%以上),鎂次之(約9%),鉀最小(約6%)。这些标准也是施肥的最低要求。 5.栽培試驗及化学分析都証明同一种离子吸附在不同的粘粒矿物上,縱然离子飽和度相等,其对植物生長和矿質养分的影响也不相等。研究結果显示出在同一离子飽和度下,不同粘粒矿物上的离子有效度大体依下列次序变化:高陵土>微晶高陵土>水化云母。在农業实踐中,不同类型的土埌所要求的施肥标准不等,在这里也得到了一些理論根据。試驗結果对于实际施肥,应有一定的指导价值。除以上主要結果外,本文还对有关代換性离子有效度的理論問題进行了討論和分析,并提出了作者自己的初步意見。

The Weihe River is the largest tributary in the middle reach of the Yellow River, flow with hyperconcentration of sediment occurs frequently, often more than ten times in a year. Based on the field data of recent twenty years, the problems such as the effects on channel degradation and aggradation, flow structure and the configuration of river, etc,have been studied, and the conclusions may be drawn as follows:1. For hyperconcentration flow, the bed of Weihe River degrades at high discharges, and aggrades at low discharges with the demarcation discharge about 1700m3/s.2.The weihe River channel is aggraded in recent ten years, that is mainly due to low discharges with high concentration. Meanwhile, armoring increases the erosion resistance of the river bed.3. In natural streams, the flow with hyperconcentration of sediment affects not only the velocity distribution along the vertical, but also the velocity distribution across the width. In the river bend, this flow causes the maximum velocity shifting from the concave to the convex bank and brings the deposition at the concave and scour of shoal at the convex.4. When the sediment concentration reaches 500-600kg/m3 in the Weihe River, the velocity distribution along the vertical still follows the logarithmic distribution. But the distribution nearly approximates to a straight line and no plug-flow exists.

本文根据渭河20年的实测资料,就高含沙水流对于河道冲淤、水流结构和河道平面形态的影响等问题,进行了初步分析研究,得到如下几点认识: 1.渭河下游有大水高含沙量冲刷,小水高含沙量淤积的特点; 2.由于十多年来渭河水少沙多,下游出现河床“粗化”现象,增加了河床的抗冲性; 3.在天然河道中,高含沙水流不仅改变垂线流速分布,而且也改变垂线平均流速分布,在弯道最大流速偏离凹岸趋向凸岸,使凹岸淤积凸岸边滩冲刷; 4.渭河在含沙量高达500~600公斤/米~3的条件下,垂线流速分布服从对数分布规律。但它几乎近似于直线,而且没有发现有流核区.
