After entering Futian, the temperature is high and the rain is frequent, and the greenhouse environment is like a "sauna room". At this time, the phenomenon of prosperous vegetables, less fruit, and frequent bacterial diseases is very serious. It is recommended that vegetable farmers do the following work in management:
When measures are taken to reduce the temperature of the shed, it is recommended to cover the shading net or spray the cooling agent in time, increase the venting opening, and extend the ventilation time so that the temperature in the shed is not higher than 35 ° C during the day, and the night temperature is preferably not higher than 18 ° C. Large temperature difference between day and night to optimize flower bud differentiation. When ventilation and cooling are difficult to work, measures such as spraying water around noon can be used to cool down.
Pruning and leafing “retaining the tail†suggests that the vegetable growers should pruning and stalking in sunny weather. When pruning, leave a stalk at the base of the side branch. When picking the leaves, pay attention to retain the petiole, so that even if the pathogen enters the wound from the rainy weather, it is only A small section of the petiole or the base of the side branch is infected, and will not immediately harm the plant itself, so that the vegetable farmers can take appropriate control measures in time.
Improve the resilience of vegetables to create a suitable environment, but also to improve the resilience of vegetables, such as seaweed, amino acids, chitin, humic acid and other functional fertilizers, while also balancing the growth of plants; Spray the boron-containing foliar fertilizer in time. Supplementing boron fertilizer can improve the quality of flower bud differentiation and reduce the appearance of deformed fruit.
Do a good job in pre-rain vegetable protection work in time to fight drugs (protection + treatment), prevent disease from happening in advance; timely dehumidification after rain, timely drainage after rain into the shed, clean up the diseased plant debris, reduce the source of infection.
