No hay insectos en el cobertizo, ¿por qué está furioso el virus?

Hora de lanzamiento:2025-08-05 Vistas de la página: El tamaño:grande en pequeño

Recientemente, el lector de Shaanxi, el maestro Liu, llamó para informar que los tomates de su cobertizo eran amarillos, parecían una enfermedad vírica, y que la velocidad de transmisión era rápida. No sé cuál es la situación. Después de una cuidadosa observación, se encontró que las hojas superiores de los tomates se hicieron más pequeñas, arrugadas, moteadas de color verde amarillento, los bordes estaban enrollados hacia arriba o hacia abajo y las plantas se empequeñecían. Sospechó que los tomates estaban infectados con por la enfermedad vírica.

¿Qué causó exactamente la aparición de la enfermedad vírica? Después de la comunicación, se supo que el maestro Liu prestaba gran atención a la prevención de plagas a diario, y no se encontraron rastros de plagas infecciosas en el cobertizo, lo que podría descartar la posibilidad de transmisión de plagas. Sin embargo, además de la transmisión de virus, la transmisión de savia también es un aspecto muy importante. Resulta que en el proceso diario de poda y ramificación, las plantas que han sido infectadas no se evitan, sino que se manejan de manera uniforme. De esta manera, la razón por la que los tomates del Maestro Liu se propagan tan rápido es por la propagación del jugo causada por el hombre durante la poda y la ramificación.

La experiencia del Maestro Liu también recordó a la mayoría de los agricultores de hortalizas: hay muchas formas de transmisión del virus, no solo se limita a la transmisión de insectos. La infección mutua causada por la poda y la ramificación también es un aspecto importante de la transmisión del virus. Se recomienda prestar atención a los siguientes puntos en la gestión:

En primer lugar, en la gestión diaria, es necesario hacer un buen trabajo en la prevención y control de insectos venenosos. A medida que aumenta la temperatura, las redes de prevención de insectos deben instalarse a tiempo. Se recomienda elegir 80 ~ 100 redes de prevención de insectos encriptadas.

En segundo lugar, se debe prestar atención a dos puntos a la hora de podar y ramificar: uno es clasificar y manejar las cepas enfermas y sanas. Durante el manejo, primero se pueden operar las cepas sanas y luego se pueden operar las cepas enfermas para evitar infecciones mutuas; el segundo es unificar el manejo, y las manos o herramientas deben desinfectarse a tiempo. Lleve agua jabonosa o desinfectante con y desinfecte una planta una vez finalizada la operación.

Nuevamente, saque las ramas podadas del cobertizo a tiempo y destrúyalas. No los tires al suelo durante mucho tiempo sin tratamiento.

Finalmente, en respuesta a la situación de enfermedades virales en el cobertizo, se recomienda que el Maestro Liu rocíe rápidamente todo el cobertizo con agentes antivirus, como los anticuerpos del virus Hei Kui, tres veces seguidas para lograr un control efectivo del virus. (Ma Yonglu)
