1.利用太阳能消毒土壤温室及塑料大棚由于长年连作,土壤中会存在大量病虫害。日本利用太阳能消毒土壤效果很好。太阳能在土壤中能有效传导、蓄热,使地表温度高达60～70℃,地表下10厘米处达60℃,20厘米处达45℃左右,能在短期内杀灭黄瓜立枯病菌,草莓萎黄病菌、芽枯病菌、白绢病菌等。方法是在盛夏气温高、不适合蔬菜生长的时期,利用大棚的保温性能,让太阳光照射。其主要优点是能够利用天然能量消毒,操作简单、安全、价廉,能杀灭杂草和作物
1. The use of solar energy to disinfect the soil greenhouse and plastic greenhouse due to years of continuous cropping, there will be a large number of pests and diseases in the soil. Japan’s use of solar disinfection soil works well. Solar energy in the soil can be effective conduction, heat storage, the surface temperature up to 60 ~ 70 ℃, subsurface 10 cm at 60 ℃, 20 cm at about 45 ℃, in the short term cucumber cucumber Rhizoctonia solani, strawberry chlorosis Bacteria, Bacillus thuringiensis, Silkworm bacteria and so on. The method is high temperature in midsummer, not suitable for vegetable growth period, the use of greenhouse insulation properties, so that the sun shines. Its main advantage is the ability to use natural energy disinfection, easy to operate, safe, inexpensive, able to kill weeds and crops
