土壤中磷酸固定作用每受外界环境之影响而有很大差异,如粘土矿物的种类,土壤反应,代换性盐基等,黏土矿物与土壤反应对于磷酸固定前,人已有较详细之报告,本文特重视代换性盐基之种类对于磷酸固定之关系。本试验以紫色土与黄壤为代表,均取于北碚。紫色土系发育于白垩纪自流井层紫色页岩,属中性而无石灰性反应,pH=7.0,黄壤系自侏罗纪灰色砂岩风化者,心土微红,pH=4.5—5.0,为避免过高之有机质,均采取心土,按照 Stoke 氏定律提取5微米(micron)直径之黏土粒,晒干后,分别以 N NaCl,N KGl,N NH_4Cl,N MgCl_2,N BaCl_2及 pH=3 HCl 处理,然后再以90%酒精洗涤至无氯为止,总之以不变更胶体之构造为原则,经处理之黏土,先分析其中之代换性盐基以及盐基代换总量,然后再测定其磷酸固定量,在酸性反应如 H~-黏土,其磷酸固定之主要因子为水化铁及水化铝,故再以 pH=2之盐酸淋洗,除去其中游离铁铝,再测定其磷酸固定量以资比较。按分析结果,黄壤胶体(<2 micron)中之(SiO_2)/(R_2O_3)为2.19,紫色土为2.56,前者盐基代换总量每百克黏土粒(<5 micron)...

土壤中磷酸固定作用每受外界环境之影响而有很大差异,如粘土矿物的种类,土壤反应,代换性盐基等,黏土矿物与土壤反应对于磷酸固定前,人已有较详细之报告,本文特重视代换性盐基之种类对于磷酸固定之关系。本试验以紫色土与黄壤为代表,均取于北碚。紫色土系发育于白垩纪自流井层紫色页岩,属中性而无石灰性反应,pH=7.0,黄壤系自侏罗纪灰色砂岩风化者,心土微红,pH=4.5—5.0,为避免过高之有机质,均采取心土,按照 Stoke 氏定律提取5微米(micron)直径之黏土粒,晒干后,分别以 N NaCl,N KGl,N NH_4Cl,N MgCl_2,N BaCl_2及 pH=3 HCl 处理,然后再以90%酒精洗涤至无氯为止,总之以不变更胶体之构造为原则,经处理之黏土,先分析其中之代换性盐基以及盐基代换总量,然后再测定其磷酸固定量,在酸性反应如 H~-黏土,其磷酸固定之主要因子为水化铁及水化铝,故再以 pH=2之盐酸淋洗,除去其中游离铁铝,再测定其磷酸固定量以资比较。按分析结果,黄壤胶体(<2 micron)中之(SiO_2)/(R_2O_3)为2.19,紫色土为2.56,前者盐基代换总量每百克黏土粒(<5 micron)为18m.e.后背为30m.e.,兹将试验所得结果归纳如次: 1.磷酸固定量每因土壤胶体之不同而有差异,由黄壤所提取之黏土其磷酸固定量亦较紫色土为高。 2.土壤之磷酸固定量,非特因土壤胶体之不同而有差异,即或同一黏土,其磷酸固定量亦因其代换性盐基之不同而有差异,概言之,钠黏土之磷酸固定量为最小,钾黏土次之钡、铵黏土又次之,而以钙黏土为最大,其磷酸固定次序为: Ca-黏土>Mg-黏土>H-黏土>B(?)-黏土>NH_4-黏土>K-黏土>Na 黏土 3.各种不同代换性盐基的粘土,加磷酸溶液后,其反应亦各不相同,H~-黏土之 pH 值为3.2—4.5,因其酸度较高,溶液中之游离铁与游离铝含量较多,是故磷酸固定量亦较高,如以淡盐酸(pH=2)洗涤,除去其中游离铁铝后,其磷酸固定量则大为减少,Na~-黏土与 K~-粘土之溶液中,因 OH 离子较多(pH=8.0—8.6),而磷酸钠与磷酸钾又为水溶性,故磷酸固定量为最少。Ca~-粘土与 Mg-粘土其反应属中性至微碱性,pH=7.5—8.0,因溶液中 Ca,Mg 离子浓度较高,磷酸则为此 Ca,Mg离子所固定,故在中性土壤中,磷酸固定以 Ca 为其主要在子,酸性土壤则以水化铁为其主要因子。 4.钙粘土所固定之磷酸,如以0.002 N H_2SO_4提取,其所固定之磷酸复可溶解,是项固定之磷酸与 Heck 所称「暂时固定磷酸」颇为相似。

1. In order to study the distribution of the two species of bedbugs,Cimex lectularius and C. hemiptera, 81 representative localities of 23provinces and Inner Mongolia were selected for the collection ofbedbugs.2. Among the 81 localities, 55 had only C. lectularius, 11 had onlyC. hemiptera, while the remaining 15 localities had both species.3. Atmospheric temperature forms one of the most important factorslimiting the distribution of bedbugs. Consequently C. hemipteralimits itself in the North at Chian-Yang of Fukien, Lo-Chang ofKuangtung, Heng-Yang of Hunan, Tsun-I of Kweichow, Ch'eng-Tuof Szechuan and Ya-An of Sik'ang. In these localities the wintertemperature is usually at 4°- 8℃. North of this belt, because thewinter temperature is much lower, the condition is not suitable forthe existence of this species. Cimex lectularius is more resistant tocold. It is, however, less resistant to extreme heat. In localities inSouth China where the summer temperature runs over 30℃, thecondition is not suitable for the survival of this species. Its southernlimit of distribution has been found to be a line connecting Amoy,Chu-Kiang of Kuangtung, Kwei-Lin of Kuangsi, P'ing-T'ang of Kwei-chow and Meng-Tze of Yunnan.4. The relationship of latitude, altitude, atmospheric pressure andhumidity to the biology of bedbugs were briefly discussed.
