氮吸附法分析生物质焦孔隙结构

采用氮吸附法对4种生物质焦(稻壳、树叶、玉米秆、棉花秆)的孔隙结构进行测量,结果表明,不同种类焦样的比表面积和孔径分布有明显差别,树叶的比表面积最大,为242.21 m2·g-1,玉米秆的比表面积最小,为0.81 m2·g-1.850℃时,稻壳、树叶、玉米秆焦样的孔径分布曲线在微孔和中孔范围各有一个分布峰,而棉花秆焦样的孔径分布曲线只在中孔范围内出现一个分布峰.热解温度是影响孔隙结构的一个重要因素,在高温条件下,同步热解得到的焦样的比表面积较大,微孔较多.在本研究中,600℃、850℃的稻壳焦样和850℃的树叶焦样具有较大的比表面积,比较适合做吸附剂.

钾肥施用量对脐橙产量和品质的影响

１９９６～１９９９年连续４年在湖北省秭归县进行了脐橙钾肥施用量田间试验。结果表明，尽管各处理脐橙产量年度变化很大，但施钾显著提高产量和经济效益，１９９７～１９９９年施钾平均增产２６．３％～４１．８％，施钾（Ｋ２Ｏ）１２５、２５０、３７５ｋｇ／ｈｍ２年均增加纯利 １０１１０、１５８４０、９９７０元／ｈｍ２，产投比分别为 １９．３８、１５．４０和７．０４；在试验条件下施钾（Ｋ２Ｏ）２５０ｋｇ／ｈｍ２增产效果最好；施钾有提高脐橙外观品质和内在品质的趋势，例如施钾提高或保持单果重、增加果皮厚度、提高维生素Ｃ含量等；但施钾对品质的影响年度间差异较大，尚需进一步研究。     

The Effect of Nitrogen and Phosphorus Fertilization on the Nitrogen Absorption by Sunflowers

Little is known about the effect of fertilization on the N uptake of sunflowers. A 4² factorial trial with 0, 60, 120 and 180 kg N ha⁻¹ and 0, 15, 30 and 45 kg P ha⁻¹ was conducted over three years. The N content and concentration of leaves, stems and capitula were determined at three growth stages. High N levels increased the N content and concentration of all plant parts at all growth stages sharply. High P levels increased the N content of all plant components through better growth. P has an inconsistent effect on N concentration but tended to decrease it. After flowering the crop assimilated 20 to 25 % of the total N. This implies that N applied can still be applied and utilized by the crop at a late stage. This should be substantiated by further research.     

Die Wurzelentwicklung von Zuckerrübenpflanzen auf einem Sandlöß-Standort und ihre Bedeutung für die Stickstoffernährung

Root development of sugar beet plants on a sandy loess site with regard to nitrogen nutrition.
Root development of sugar beet plants in a sandy loess soil (Haplic Phaeozem) was observed from the early seedling stage up to harvest by measuring at first the greatest vertical and lateral extension of the root systems of single plants and later the rooting density of the whole plant stands (auger method, profile wall method).
During the seedling stage not only the subsoil, but also large parts of the topsoil between the plants remained unoccupied by the root systems. In this phase the greatest lateral extension of single roots reaches nearly the length of the greatest leaf of the plant. With the closure of the canopy the rooting density in the topsoil accounts to 1–2 cm cm⁻³.
In summer roots penetrate to a depth of 100–150 cm with rooting densities of 0.1 to 1 cm - cm⁻³. Thus, the plants gain not only access to water reserves, but sometimes meet remarkable amounts of nitrate which under the relatively dry conditions of the region tends to accumulate in 60–120 cm depth and – when taken up by the beet plants in the late stage of growth – affects crop quality negatively.

不同碳源氮源对腐霉菌株生长的影响

在喀麦隆芋芳根涡病病原研究中，测定了不同碳源、氮源对分离自喀麦隆芋艿田间及来自中国的腐霉菌株生长习性的影响。实验结果表明，除了钟腐霉（Ｐｙｔｈｉｕｍｖｅｘａｎｓ）菌株只能吸收葡萄糖、果糠而不能吸收蔗糖外，其余腐霉菌株均能利葡萄糖、果糖、蔗糖作为碳源。所有试验菌株均不能利用半乳糖、麦芽糖及可溶性淀粉。钟腐霉菌株之形态特征与特殊碳源营养的相关性显示了用碳源作为菌株鉴定辅助标准的可行性，氮源营养试验结果表明，所有腐霉菌株均能利用四种氮源，根据不同氮源对菌丝生长的影响，依次为Ｌ－天门冬氨酸，Ｌ－精氨酸，硝酸铵，硝酸钾。
