鉴定结果表明:用气态状况下的磷化氢(H_3p)处理马铃薯块茎,再把处理的块茎进行栽植,便可看出此种处理方法对其生长发育有明显的促进作用。处理块茎的方法是:碱性或碱性土壤金属磷化物在水解作用下释放出磷化氢(H_3p),再用H_3p来处理块茎就可表现出上述作用。使用生长刺激素能使处理过程机械化达到90％,并且用在块茎发芽上的费用消耗与常规 Identification results show that: treatment of potato tubers with gaseous phosphine (H_3p), and then the treatment of tubers for planting, we can see that this treatment has a significant role in promoting its growth and development. The treatment of tubers by alkaline or alkaline soil metal phosphide phosphine release under the action of phosphine (H_3p), then H_3p tubers can handle the above-mentioned role. The use of growth-stimulating hormone can make the process mechanized up to 90%, and the cost spent on tuber germination and conventional
