    1. This is a report of the discovery of a widespread, probably infectious pneumonia of goats in the Canton area, based on X-ray diagnosis. Of a total of 1464 goats examined, 339 positive cases were encountered. Autopsy of 14 positive cases all confirmed the X-ray diagnosis, whereas postmortem findings of 16 negative cases showed accordance in 14 cases. Owing to the fact that X-ray examination in this disease affords rapid and early diagnosis, acquaintance with the development of the pathological state, timely isolation and treatment of sick animals, as well as assessment of therapeutic effect, it assumes an important place in mass scale veterinary inspection and clinical practice among goat herds. 2. X-ray presentation of this disease is amalgamative broneopneumonic shadowing in the lower part of the pulmonary field. Pathologic changes are most frequently encountered in the cardiac and apical lobes, extending to the diaphragmatic lobes in serious cases. Lesions persist for a long time but often show spontaneous disappearance on continued observation. Secondary fibrosis of the lungs and bronchiectasis were met with in a few cases with bad courses. 3. The incidence of this disease is high, 23.15% of 1464 goats being found infected on X-ray examination. The incidence of One milk goat herd was found to be 43.15%, with a high 69.2% among the immature females. Clinical findings were cough, nasal discharge, increase in rate of respiration, a chronic course with rather long duration, no response to penicillin, streptomycin, sulfathiazole, neoaspharmine and with only partial therapeutic effect in the case of terramycin. This disease seems unlike primary broncho-pneumonia, contagious pleuropneumonia of goats. Pasteurella pneumonia, diplococcal pneumonia, pulmonary type of infectious agalactia of goats, and is suspected to be another kind of infectious pneumonia. Methods to raise the accuracy of X-ray diagnosis, as well as immediate steps to control the disease have also been discussed.

    This paper sums up the results obtained from more-than-ten-year studies of the fertilizer practice through nutrient diagnosis(leaf analysis)of rubber trees. It falls into three parts: the time for sampling, the critical values for nutrient diagnosis and the effect of trial application on plantations,Investigations on the variation of leaf nutrient contents in different Stowing stages of rubber trees in South China showed that less fluctuation occurred in the contents of nitrogen, phosphorus, potassium, calcium and magnesium in the lower shaded leaves during the period from July to September, which is therefore dasirable for sampling to make leaf analysis and determine the fertilizer requirements, because the nutrient analysis of leaves collected in this period is more accurate.Studies on leaf nutrient eontents of and fertilizer effect on the rubber trees differing in clone and growth on different soil types under different managements brought about the following critical values for healthy, normal-yielding rubber trees: N 3.2-3.4%, P 0.21-0.23%, K 0.9-1.1%, Ca 0.8-1.0%, Mg 0.35-0.45%. This method tends to result in accurate diagnosis of the nutrient status of rubber trees. Fertilization based on the diagnosis can enhance the effect of fertilizers, thereby increasing the yield by 10-20%. The results of field experiments proved that this practice is effective and suitable for rubber enltivation in South China.

    本文总结了十多年来橡胶树营养诊断(叶片分析)指导施肥技术的研究结果,包括叶片采样时间、营养诊断指标和生产上试用的效果。结合我国橡胶树生长情况,研究不同时期叶片养分含量的差异后,确认低部位荫蔽叶片的氮、磷、钾、钙、镁养分含量的差异在7—9月间较小,与施肥的关系表现显著。故以7—9月为叶片分析诊断橡胶树需肥量的适宜采样时间。在此期间采样,诊断的准确性高。研究了不同土壤类型上不同品种、不同生长类型、不同管理下的橡胶树叶片养分含量和施肥效应后,得出生长健康、产量正常的橡胶树叶片营养指标是:氮3.2~3.4%,磷0.21~0.23%,钾0.9~1.1%,钙0.6~1.0%,镁0.35~0.45%。应用此项技术,可以确切地诊断胶树营养状况,据此对症施肥,可以提高肥效,增加产量10~20%。经过田间试验应用的结果,这是符合我国情况的有效技术。
