应用401抗菌剂防止甘薯在储藏期和运输途中霉烂,我们在1961、1962年多次进行小型、中型、大型试验,都证明401抗菌剂防止烂薯有显著的效果。 为了进一步摸清401抗菌剂对几种主要为害甘薯微生物的有效剂量(据中国科学院上海有机化学研究所报导:401抗菌剂对甘薯黑斑病菌最低制菌浓度为11微克/毫升),研究改进剂型和使用操作方法,以提高效果、降低药剂成本,进行了一系列的剂量和剂型的室内试验: 一、“401”对黑斑病菌分生孢子的药效测定: 1.密闭条件好的:在马铃薯蔗糖洋荣培养基上(以下简称培养基),接入甘薯黑斑病菌分生孢
Application of 401 Antimicrobial to prevent sweet potato during storage and shipping rotten, we in 1961, 1962 many small, medium, large-scale test, have proved 401 antimicrobial agent to prevent tuberculosis have a significant effect. In order to find out the effective dosage of 401 antibacterial agent against several kinds of main harmful sweet potato microorganisms (according to the report of Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences: 401 antibacterial agent has the lowest bacteriocidal concentration of Alternaria solani 11 micromol / ml) And the use of methods of operation to improve the effectiveness and reduce the cost of pharmacy, conducted a series of dose and dosage forms of laboratory tests: First, the “401” on the Alternaria spores conidial determination: 1. confined conditions: good Potato sucrose Yang Rong medium (hereinafter referred to as medium), access to sweet potato Alternaria spores
