| | The present paper reports studies on the relative rate of decomposition of nine different oil cake-meals [soybean, peanut, sesame, rape seed, cotton seed(with and without hull), chinese tallow seed (with and without hull)]. In the course of decomposition of the different oil cake-meals, freguent measurement were made of the quantity of evolved CO_2 gas, and amount of the NH_4~+, NO_3~-, and NO_2~- nitrogen formed at the given intervals of the day. These measurement served as indices of the intensity of deco... | | 研究了浙江省施用的九种主要餅肥在土壤中分解的情况,各种餅肥都經磨碎,并通过20孔篩。实驗証明,在夏天的温度下,餅肥施入土壤后即迅速分解,它的分解最盛时期是在一星期左右,此后即迅速下降,到二星期后,即漸趋穩定。餅肥施入土壤后,铵态氮的大量發生是在一星期以內,此后即迅速降低,轉化成硝酸态氮。硝酸态氮在一星期到二星期的时間内开始大量發生,到二星期后就漸趋穩定。土壤中有效态氮总量在各个形态轉化的过程中,有顯著的減少趋势。餅肥在施入土壤前用石灰、草灰或水处理一星期,可提早土壤中有效氮的發生,其中單用水处理的效果尤其好。实驗証明,用石灰或草灰处理餅肥,使有效态氮大量損失,而用水处理則沒有这种情况。在本实驗的条件下,各种餅肥的分解速率依次为:豆餅、芝麻餅、花生餅、棉仁餅>棉籽餅、生菜餅、熟菜餅>桕餅、青餅。各种餅肥中氮素化合物转化后所產生的有效态氮总量依次为:豆餅、花生餅、芝麻餅、青餅>棉仁餅、生菜餅、棉籽餅>熟菜餅>桕餅。 | | 文摘来源 | | 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... | | 在蒙脱石系、高陵石系及水化云母系的培养基里,人为地调节 Ca、Mg、K 三种代换性阳离子的饱和度,把其中任意两个阳离子的饱和度维持不变,而把其余一个阳离子作为陪补离子,调节其饱和度,使其在适当的范围内变化,以观察其对植物生长及其组织的化学组成的影响。试验的主要结果,简要地总结如下:1.陪补离子对代换性阳离子的有效度的影响,无论在高陵石系中或蒙脱石系中,结果都是一致的。这说明它们之间有共同规律可循,和粘粒矿物的种类无关。2.陪补离子钙对代换性镁离子的有效度有不利的影响。反之,陪补离子镁对代换性钙离子的影响也相同。3.作为陪补离子的钙,当其饱和度增大时,代换性钾离子的有效度亦随之而增加。但反之作为陪补离子的钾,当其饱和度增大时,却反降低了代换性钙离子的有效度。4.至于镁离子和钾离子间的相互影响,则情况和钙、钾之间的相互影响同。(见3)5.水化云母系的试验结果表明:对代换性钾离子的有效度而言,作为陪补离子的钙比镁更为理想,而对代换性钙离子的确效度言,则陪补离子钾又比镁更为理想。6.从试验结果看来,在含同量代换性钾及同一盐基代换量的条件下,钙质粘土的钾素供应状况应优于氢质粘土。这对酸性土壤提供了一种新的看法,并对酸土... | | 文摘来源 | | Field observations and laboratory studies revealed that the “white soil” in Tai Lakeregin was formed as a result of surface water-logging.The iron content of the wholesoil and the clay fraction in the “white horizon” at a depth of from about 25 cm to 40cm was rather low,and as a consequence the alumina/iron oxide ratio of the “WhiteHorizon” was high as compared with other horizons.The soil differed from the “de-graded paddy soil” of Japan in that it was not a result of present-time formation.The infertility... | | 根据研究结果,认为太湖地区的低产白土,曾经遭受过一定程度的表面潜育过程。但是白土层的出现,并不是现代水稻土成土过程的产物,而且这种白土的特性,又与太湖地区的一般脱沼泽土不同。这种白土的低产原因,是由于施肥过少,因而有效养分,特别是氮和磷比较缺乏所致。物理性质不良也可起有一定影响。由于有机质含量和胶体含量都较少,所以保蓄养分的能力也较差。通过田间试验证明,深耕结合施用大量有机肥料,可以变低产为高产,在一次改良措施后,水稻即可增产一倍以上。 | | 文摘来源 | |   | | << 更多相关文摘 |
