    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,根据增产百分率的...

    The v(OH) region of syn-and anti-2-hydroxy-4-sec-octyl-and 2-hydroxy-3-sec-ctyloxybenzophenone oxime was observed at various concentrations in order to study their tructure. The substituted anti-2-Hydroxy-benzophenone oxime in CC1_4 shows a free absorption vOH)of oxime group at 3580cm~(-1), but the phenolic hydroxyl group chelates with the nitrogen tom of oxime by intramolecular hydrogen bond resulting in a stable six-member ring, its v (OH) hows weak multiplets overlapped on v(CH) absorptions. However, the phenolic group of the syn--ydroxy-benzophenone oxime is free from association, its v(OH) appears at 3580cm~(-1), and the olecules exist in dimer form due to intermolecular association between two oxime groups and hows broad and medium strong absorption near 3200 cm~(-1). Infrared spectra of the copper omplexes of the substituted anti-hydroxbenzophenone oxime indicate that the structure of the omplexes is probably formed through the interactions of two extractant molecules with one upric ion in the stable trans form as shown in the Chinese text.
