用室内测定及田间试验的方法,从10种供试药剂中筛选出1号、3号、4号、5号、10号等5种防霜剂,用于防除INA细菌,减轻蚕豆霜冻,效果稳定。在此基础上开发的农大防霜剂5号,防霜效果好,能使蚕豆增产10%～20%,具有良好的应用前景。
ＭＢ５０式冲锋枪是仿照丹麦麦德森１９４６式９ｍｍ冲锋枪设计的，只是将口径改为１１．４３ｍｍ，并将拉机柄由机匣上方移到机匣右侧，其他结构基本相同。该枪于１９５０年至１９５３年大量生产。１９５３年底，巴西国营武器工业公司对ＭＢ５０式进行了改进，定名为Ｍ９５３式１１．４３mm冲锋枪。这种冲锋枪曾在巴西武装部队和警察中广泛使用，而且也曾向南美洲其他国家出口。目前，ＩNＡ ＭＢ５０式和Ｍ９５３式１１．４３ｍ...
