殺菌銾藥劑的製備:本所製備的殺菌銾製劑:(一)乙基氯化銾,相當於美國貨‘西力生’;(二)乙基燐酸銾,相當於美圃貨‘谷樂生’;經華東農林部派員試驗,證明:其對棉籽立枯病菌、炭疽病菌和紅腐病菌的生長抑制作用,和撲滅孢子的效用,均較美國貨更强。(但這或許是因爲美國貨經過久留,效力減低之故)現在工作,一方面,由華東農業科學研究所進行田間藥效的比較試驗;另一方面,則在以電解食鹽水製造鈉銾齊作爲製造殺菌劑的原料,使其成本减低而便於大量生產。半工廠性試驗在計劃進行中。 膠狀石墨的製備:膠狀石墨。在無線電製造上應用很廣。本所接受華東工業部的委託,代爲製 Preparation of bactericide 銾 agent: The preparation of bactericidal 銾 preparations: (A) ethyl chloride, equivalent to the United States of America ’Lisili’; (B) ethyl 燐 acid 銾, equivalent to the United States nursery goods ’Gule Sheng’; The East China Ministry of Agriculture and Forestry dispatched personnel to prove that: its growth on cottonseed Rhizoctonia solani, anthracnose and red rot bacteria growth inhibition, and fight the spores of the utility, are stronger than the United States. (However, this may be because American goods persist for a long time to reduce their effectiveness.) Now working on the one hand, the East China Institute of Agricultural Sciences field trials of comparative efficacy; the other hand, As a raw material for the manufacture of fungicides, to reduce the cost and ease of mass production. Half-factory testing is underway. Preparation of colloidal graphite: colloidal graphite. It is widely used in radio manufacturing. The Institute accepted the East China Ministry of Industry commissioned on behalf of the system
