The phenomenon of prosperous vegetables, less fruit set, 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 "leaving the tail"
It is recommended that the vegetable growers 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 wound in rainy weather, it is only a small section of the petiole or the base of the side branch. Being infected will not immediately harm the plant itself, and it is convenient for the vegetable farmers to take appropriate prevention measures in a timely manner.
Improve the resistance of vegetables
While creating a suitable environment, it is also necessary 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; in addition, timely spraying of boron Foliar fertilizer. Supplementing boron fertilizer can improve the quality of flower bud differentiation and reduce the appearance of deformed fruit.
Do a good job in vegetable protection before the rain
Timely spraying (protection + treatment) before the rain, prevent the occurrence of diseases in advance; timely dehumidification after the rain, timely drainage after the rainwater enters the shed, clean up the residuals of the diseased plants, and reduce the source of infection.
