国外蔬菜科技利用太阳能防治病虫害 此法是利用夏季高温农闲期,通过施用有机物、注水、地表覆盖塑料薄膜等综合处理,利用太阳能提高地温达40～45℃,持续8～14天,以热消毒方式进行杀菌、杀虫、除草,同时改良土壤的理化性质,并维持土壤有益微生物的生态体系。 具体做法首先是清除
Foreign vegetable science and technology using solar energy to prevent pests and diseases This method is the use of summer high-temperature agricultural leisure period, through the application of organic matter, water injection, plastic film covering the surface covered by the use of solar energy to improve the temperature up to 40 ~ 45 ℃ for 8 to 14 days, For sterilization, insecticide, weeding, at the same time to improve the physical and chemical properties of the soil, and maintain the beneficial microbial ecosystem of soil. The specific approach is first clear
