Autumn winter is coming. How's your greenhouse cucumber growing? Are you worried about how to deal with the new threat of disease? This paper will focus on ways to effectively combat the vulnerability of cucumbers in the autumn and winter greenhouses and to ensure their healthy growth。
The planting of greenhouse cucumbers in the autumn and winter is widespread and widespread, especially in the form of atrophy, disease, frost, anthrax, etc., which causes cucumber leaves to decay and to die, as well as limited fruit growth, which greatly affects yields and quality。
Specific responses
In particular, it can help cucumber grow robustly during the autumn and winter season, starting with the selection of varieties, soil management and pharmaceutical control。
Preparation for decontamination
The remaining leaves and weeds in the greenhouses are completely removed and greenhouse facilities, planting equipment, etc. Are disinfected. The number of bacteria can be reduced and potential sources eliminated earlier。
Selection of excellent varieties
The selection of more resistant cucumber varieties for disease and pests can offer some resistance to disease and significantly reduce the incidence of disease。
3. Be careful with rational fertilization and maintain soil nutritional balance
The slower release of soil fertilizers during autumn and winter requires long-term, balanced and stable fertilization and a reasonable proportion of nitrogen, phosphorus and potassium fertilizer to prevent cucumber plants from growing too well and becoming susceptible to disease。
4. Focus on humidity and temperature management in greenhouses
Active ventilation, avoidance of water retention and control of appropriate temperatures are needed to help plant resistance。
5. The appropriate selection of pesticides to combat disease
During the cucumber boom, before flowering, during the outcome period, the cucumbers were released from the disease using ®10 g + 20 g ® ® (35% 寡 喹啉 铜 酯 ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® ® 。 。 ® ® ® ® ® ® ® ® ® 。 。 。 。 。 。 ® ® ® ® ® ® ® ® ® ® ® ® + + + + + + +。
Note: note that the best use is made before the disease occurs, and more therapeutic use is recommended at the epidemic stage。
