In general, the diseases of fruit trees can be divided into four categories, fungal diseases, viral diseases, bacterial diseases, and physiological diseases. Today, Xiaobian talks with you about the prevention and treatment of vegetable fungal diseases. I hope everyone Helpful. Fruit tree fungus control methods: 1. Seed dressing with fungicide . 2. Clean the garden and timely bury the diseased leaves, diseased fruits and diseased plants out of the field or burn them. 3. Rotating the recommendation, adding organic fertilizer and phosphate fertilizer. 4. Strengthen the ventilation in the protected area such as the greenhouse, and pour small water under the membrane to reduce the humidity. 5. The fungicides such as chlorhexidine, mancozeb, carbendazim, chlorothalonil, kelu, toxic myricium manganese zinc have certain effects on most fungal diseases, and can be used as appropriate. Common fungal disease medication standards (1) Downy mildew, prevention and control of epidemics: the choice of agents, 53% Jin Lei Duoer 600 times liquid, 72% metalaxyl manganese zinc 500-600 times liquid, 66.8% mildew 600 times liquid, 70% Antai Raw (zinc-rich) 500-700 times solution, 600 times liquid or 600 times liquid. (2) Prevention and control of powdery mildew and rust: biomimetic pesticide -green emerald powder or powder rust 1000 times liquid, 40% virulence suspension agent 300-400 times liquid, 25% enemy power off 1000 times liquid, Xiansheng 800 Double liquid, get 2000 times liquid or spray 600 times liquid. (3) Control of Fusarium: 2.5% timely suspension seed dressing and timely 2000 times liquid, 500 grams of wilted gram, 500 times liquid, 50% methyl thiophanate 400 times liquid and other roots. (0.3-0.5 kg per solution) More pesticide knowledge, please pay attention to China Pesticide Network
The vacuum tube collector with CPC (Compound Parabolic Concentrator)
reflector has high energy yield due to special collector structure that
contains Vacuum Tubes with highly selective absorber layer, U-shape copper
pipes inside vacuum tubes for heat transport, aluminum heat transfer fin and
highly reflecting CPC reflector. The CPC reflector ensures that direct and
diffuse sunlight will fall onto the absorber inside of tubes, even at the back
of tubes. The CPC reflector can improve collector efficiency by 15%
