In Xiqing Pizizi Village, Tianliu Town, Shouguang City, the Zhu Institute was mentioned. The farmers all gave thumbs up and praised him for his good management of the tomato. “The Laozhu couple manages the tomato is a set, the tomato yellow leaf curl virus disease is so serious in these two years, we are afraid to plant susceptible varieties. But others are shed tomatoes are all susceptible varieties. It is also planted at the end of July. However, there was no disease, and farmers praised the Zhu Institute. What are the tricks of Lao Zhu's two spouses, so that their three shed tomatoes do not get infected with the yellow leaf curl virus disease? “Nothing is outstanding. I think that this year's anti-yellowing disease has been successful, mainly with the idea of ​​early prevention, and all the work is done in detail, especially in the outlet vent effort.†Zhu learned to laugh. Front and rear vents 5 days ahead of time to install insect nets "I cover insect nets earlier than anyone else's home. This year, I covered insect nets in the front and rear air outlets 5 days before the emergence of tomatoes. Then sprayed imidacloprid, acetamiprid and other drugs in the shed, or smoked with IsoVenture. I also hanged a yellow sticky board in the shed, so that I can use the medicine to prevent and treat it as soon as I see the whitefly on it.By adopting these conventional measures, when my tomatoes are planted, there is basically no ash in my greenhouse. After the tomato is planted, only the shed entrance is the way for pests to enter the shed, so you should pay attention to close the door when entering or exiting the greenhouse. By adopting the above series of measures, you can ensure that there are no pests (mainly whiteflies) and cut off the spread of the virus. Some farmers have reported that they have no effect after covering the insect nets. I have pondered that they usually cover insect nets when the tomatoes are planted or after planting. The time is a bit late and the effect is much worse, Zhu learned. The Zhu Society also emphasized that the size of the air outlet of the greenhouse should be measured before the cover insect nets. The insect net must be longer than the outlet and have a wide point. It is necessary to overlap with the film. The upper part of the shed at the upper part of the insect net is tied with a rope to the film rope. The insect net on the front face of the shed is dragged to the bamboo pole and the column with the rope, and the earth is pressed on the ground with the lower end. Summer does not close the upper air outlet of the shed In midsummer, the temperature is high and the rain is high. To prevent the death of the tomatoes caused by the rainwater irrigation, the vegetable growers will close the air outlet behind the shed in rainy days. Although this can prevent rainwater from irrigating, after the air outlet is closed, the temperature in the shed increases, the nutrient consumption of the plant is large, and the resistance is reduced, thus creating conditions for virus infection. The tomato greenhouses of the Zhu Institute have never closed down in the upper summer, whether it is raining or sunny. "At the beginning, I covered the film under the vent to prevent rain, but I found that this would affect the ventilation conditions in the shed, and it was not conducive to cooling. Later, I placed a 1.2-meter-wide mulch on the underside of each shelter outlet. Does not affect the ventilation, but also to prevent the rain splashed on the plant caused dead seedlings." Zhu learned to say. Open the front of the shed to release the air outlet, depending on the weather conditions This summer, many vegetable farmers are worried that yellow leaf curl virus disease will spread through the air flow, and they dare not open the vents at the front of the shed. However, the courtyard of the tomato greenhouse of the Zhu Society has been open for sunny days. “In the summer, my management focus was on reducing the temperature inside the shed, so the front face of the shed was not closed, but there was a difference in the size of the open. When the wind was small, the bleb was wider, and when the wind was large, the bleb was slightly smaller; the rain was short. The time was closed, and many vegetable farmers did not dare to open the front of the greenhouse in the summer. I think this is a mistake. In the summer, if you don’t open the front of the greenhouse, the temperature inside the greenhouse will be too high, which will not only increase the risk of tomato yellow leaf curl disease. It will also affect the differentiation of flower buds and affect fruit setting," Zhu learned.
