“西瓜重茬剂1号”是北京市水利科学研究所高级工程师丁正熙主持的北京市科委重大项目“西瓜土壤消毒重茬增产技术研究”课题组,经过5年刻苦攻关研制成功的成果,本项技术1992年底通过北京市科委主持的专家成果鉴定。鉴定会认为:该项研究成果是西瓜生产的一个重大突破,在解决西瓜重茬生产方面属国际先进水平。复合型“西瓜重茬剂1号”集杀菌与刺激生长于一体,对防治西瓜枯萎病,实现重茬增产有特效,防治效果达75.4%—88.1%。对其它瓜类、蔬菜等作物的枯萎病、炭疽病、霜霉病、白粉病等真菌病害亦有效。经北京市食品卫生监督检验所、北京农业大学食品检测中心等部门检测,施用重茬剂生产的西瓜,完全符合国家食品卫生标准。本项技术成果实现了西瓜可连作7年,亩产量仍达5000公斤左右的水平,西瓜重茬增产技术的突破,产生了两个效果。
“Watermelon stubble agent 1 ” is the Beijing Municipal Science and Technology Institute of water conservancy researcher Ding Zhengxi presided over the Beijing Municipal Science and Technology Commission major project “watermelon soil disinfection stubble yield increase technology research group,” after 5 years of painstaking research achievements By the end of 1992, this technology was appraised by experts from Beijing Science and Technology Commission. Appraisal will think: The research results is a major breakthrough in the production of watermelon, watermelon in the resolution to solve the problem of crop production is an international advanced level. Compound type “watermelon stubble agent No. 1” set bactericidal and stimulating growth in one, the prevention and control of watermelon blight, to achieve the effect of stubble increase, the control effect of 75.4% -88.1%. Fusarium wilt, anthracnose, downy mildew, powdery mildew and other fungal diseases of other melons, vegetables and other crops are also effective. The Beijing Municipal Food Sanitation Inspection and Inspection Center, Beijing Agricultural University Food Testing Center and other departments testing, application of stubble agent produced watermelon, in full compliance with national food hygiene standards. Achievements of this technology can be continuous watermelon for seven years, the mu yield still reached the level of about 5000 kg, watermelon continuous cropping breakthroughs in technology, resulting in two results.
