Six chemical methods with different extractions for determining readily available phosphorus (RAP) content of three types of acid paddy soil in Jilin Province were studied.And the RAP contents evaluated from these methods were compared with A-value calculated from isotopic method with 32P and the quantity of phosphorus in seeds.Results showed that the correlation coefficient of RAP contents from Al-Abbas method to A-value (r = 0.89>r0.01=0.834),to the quantity of phosphorus in seeds (r = 0.754>r0.05=0.707) ,...

本文以~(32)P示踪法测得的“A”值与盆栽试验水稻吸磷量为标准参比项,用6种化学提取法对吉林省3种酸性土壤的磷素形态进行研究。结果表明,Al—Abbas法与“A”值和水稻吸磷量分别达极显著相关与显著相关,与供给水稻磷素的主要磷源磷酸铁星极显著相关。建议在吉林省酸性水稻土上速效磷的化学提取法应采用Al—Abbas法。

It was shown in this experiment that all compound fertilizers tested had a significant effect on yield of rice compared with control. The range of increased grain yield was 60.8-77.7%. But there was no significant difference among the compound fertilizers. By using isotope 15N tracer,the efficiency of nitrogen utilization by rice was found as follows:urea-ammonium phosphate 44.65%,ammonium phosphate-chloride 44.54%,urea 44.12%, nitric phosphate 36.65%. The nitric phosphate could not be used in paddy field.The...

在盆栽条件下几种复(混)合肥料对水稻均有增产作用,与对照相比稻谷增产60.8—77.7%,达到显著水准。但几种复(混)合肥之间无显著差异。用15~(N)示踪法测定水稻对复(混)合肥的氮素利用率:尿素磷铵为44.7%,氯磷铵为44.5%,尿素为44.1%,尿素加普通过磷酸钙(简称普钙)为40.8%,硝酸磷肥为36.4%。说明硝酸磷肥不宜于水稻田施用。用~(32)P示踪法测定水稻对几种复(混)合肥的磷的利用率:硝酸磷肥为22.6%,氯磷铵为22.4%,尿素磷铵为21.1%,尿素加普钙为20.7%,普钙为11.9%。水稻对供试复(混)合肥料磷的利用率均显著高于普钙。

: The fractions and quantities of root exudate containing P from seedlings of Chinese Pine (Pinus tabulaeformis) and 3 leguminous sp-ecies (Melilotus suaveolens, Astragalus adsurgens and Corolilla uaria) were determined, and the interrelation of root P nutrition between Chinese Pine and legumes were investigated, The exudation rates of P from root system are 15-23% for Chinese Pine,5-14% for legumes. The water soluble fraction ranges 66-76%,the lipophilic fraction ranges 15-19% of the total exudate containing...

: The fractions and quantities of root exudate containing P from seedlings of Chinese Pine (Pinus tabulaeformis) and 3 leguminous sp-ecies (Melilotus suaveolens, Astragalus adsurgens and Corolilla uaria) were determined, and the interrelation of root P nutrition between Chinese Pine and legumes were investigated, The exudation rates of P from root system are 15-23% for Chinese Pine,5-14% for legumes. The water soluble fraction ranges 66-76%,the lipophilic fraction ranges 15-19% of the total exudate containing P, the rest is P containing proteins. The study shows that there is obvious communication of P-containing substances between roots of Chinese Pine and legumes, It has been suggested that the intercropping of Chinese Pine with Astragalus or Melilotus may be more beneficial in P nutrition than with Corolilla.

本文用~(22)P示踪法测定了油松和豆科植物的含磷根系分泌物的组分和数据,并研究了两者的相互关系。据测定,油松的含磷根系分泌物的排出率为15~23%,豆科植物为5~14%。含磷根系分泌物中。水溶性组分约占66~76%,脂溶性组分15~19%,其余为含磷蛋白质。试验证明,在油松与豆科植物之问,存在着明显的含硫化合物交流现象。根据上述材料,作者认为油松与沙打旺、草木间作,在磷素营养方面可能比与小冠花间作更有利。
