Chemical analysis of seperate plant organs of green manures at various stages of growth collected from representative districts of Central China showed that the accumulation of green mass and the absorption of nutrients chiefly occurred during the last 30 to 45 days before plowing-under.Astragalus sinicus,the principal leguminous green manure in central China,showed some correlation in P and K contents with soil fertility,whereas the nitrogen content remained practically constant regardless the nutritive status of the soil.It was esti- mated that the nodular bacteria of Astragalus sinicus assimilated about 105 kg of nitrogen per hectare at the yield of 37,500 kg of green mass. Green-house experiments revealed that manure crops possessed a stronger power in assi- milating their phosphorus from rock phosphate and magnesium from serpentine as compared with winter wheat.Laboratory experiments with exciled root also demonstrated that the root systems of manure crops have a stronger absorption power,greater cation-exchange capacity,larger absorbing surface area and more intensive rate of respiration than that of the wheat.Among the tested manure crops,Raphanus sativus,a cruciferous plant widely planted on infertile soils,has been proved the best variety.

1.紫云英与苕子的绿色体一般以初花期前后或盛花期增长最快。紫云英的根系主要分布在0—10厘米,在5,000斤鲜草产量时,1平方尺内约有6克左右的干根。地上与地下部分的干物质比为6.5∶1,鲜重比为11∶1,目前一般对地下部分的产量估计似乎有些偏高。2.紫云英等含氮、磷、钾的百分率均随绿色体的增长而减低,紫云英在盛花期含 N2.7%,P_2O_5 0.65%,K_2O2.5%,CaO 1.6%,含氮量与土壤的肥沃程度没有明显的相关性,含磷量与含钾量则与土壤中磷钾含量成正相关。根部所含的养分一般均低于地上部分,叶子的氮、磷百分率远较茎等部位为高。苕子盛花期含 N 3.3%左右,其他成分大体与紫云英相近。萝卜菜在盛花期的含 N 量为1.7%,K_2O 量较高,一般是 N 与 P_2O_5的总和,含 CaO量恒多于紫云英,一般在2.0%以上。油菜的成分大体与萝卜菜相近。3.各种绿肥在一定生长时期中地上部分的阳离子总量大体为一常数。紫云英在盛花期的阳离子总量维持在110毫当量左右,萝卜菜的含量还更高。4.萝卜菜、紫云英、苕子与小麦等四种植物对蛇纹石都能利用,但对钾长石不能利用。磷灰石的施用对增产很显著,根据...

The complexometric titration method of Bennewitz and Tanzer was improved to determine the phosphorus content of a few organophosphorus componuds containing C—P bonds. In order to obtain accurate rcsults, certain aspects such as the volume of the combustion flask, the duration of boiling and the purity of reagents must be noticed. It was found that the addition of potassium cyanide was unnecessary for common organophosphorus compounds. The absolute errors were less than 4±0.3%.

本文从铸造合金角度,用大量实验数据验证磷含量、碳当量、孕育、熔炼和孕育温度对普通机床导轨用含磷耐磨铸铁性能的影响;并指出含磷耐磨铸铁的耐磨性,除金属基体外更主要决定于磷共晶及石墨的含量、形状和分布。 本文根据实验数值并用理论分析了铸铁共晶团与磷共晶间的关系,指出其规律:凡是细化共晶团的因素,大都是细化磷共晶的因素,同时亦是形成A型石墨的因素,而有利于耐磨性能的提高。 为了细化共晶团,含磷耐磨铸铁必须具备一定的含磷量,碳当量,采用孕育处理且应孕育温度适宜(不宜过高);此外并指出采用双重孕育可能更为有利。 本文否定了习惯的看法:铸铁的耐磨性能与抗张强度,尤其是与硬度之间有直接比例的关系,提出应用综合性能来衡量铸铁的质量,并认为比强度、比硬度等指标有其实际意。 本研究确定了机床导轨含磷耐磨铸铁最适宜的化学成分及熔炼处理工艺,供生产参考。 铸铁成分为C≈3.0~3.3%;P≈0.5~0.7%;CE=3.8~4.0%;Mn=0.6~0.8%;S<0.12%(导轨壁厚约40~60毫米)。 熔炼处理工艺:过热温度1400~1480℃;孕育温度1380~1440℃;孕育剂数量0.6~0.8%硅铁(75%Si);浇...
