Embodiment 1

[0015] Example 1, tomato was cultivated with delayed cropping in autumn in solar greenhouse at a certain vegetable greenhouse in Shouguang, Shandong Province, and the experiment was continued for 2 years. The first year: sowed on July 5, 2012, planted on August 10, the variety is FA-1420, which is not resistant to yellow leaf curl virus disease; the second year: sown on June 30, 2013, July 25 Colonization, the variety is Provence, the variety is not resistant to yellow leaf curl virus disease.

[0016] Tomatoes are cultivated in rows according to size, with a large row spacing of 80cm and a small row spacing of 60cm; 15-20 days before tomato planting, Abutilon is transplanted. 20cm; plant a row of velvetleum in the middle of the small rows of planting rows, with a plant spacing of 2.0m; after the fifth ear of tomato is settled, pull out the velvetleum between the small rows.

[0017] Abutilon adopts plug-in seedlings for seedling cultivation, and Abutilon grows seedlings 40-4...

Abstract

The invention discloses a method for preventing and treating tomato yellow leaf curl virus diseases. The method includes cultivating tomatoes in sunlight greenhouses in large rows and small rows; transplanting abutilon theophrasti 15-20 days before the tomatoes are planted in fields; planting one row of abutilon theophrasti at the planting distances of 20cm along the inner side of the root of a north wall of each greenhouse; planting a row of abutilon theophrasti at the planting distances of 2.0m between each two adjacent small field planting rows; pulling out the abutilon theophrasti among the small field planting rows after fruits of fifth panicles of the tomatoes are set. The row spacing of the large rows of the tomatoes planted in the sunlight greenhouses is 80cm, and the row spacing of the small rows of the tomatoes planted in the sunlight greenhouses is 60cm. The leaf age of the abutilon theophrasti is 4 leaves and 1 core when the abutilon theophrasti is transplanted. The method has the advantages that the incidence of the tomato yellow leaf virus diseases can be effectively reduced, and the incidence of tomato yellow leaf virus disease infected tomato varieties can be within the range of 10% under the control generally.

Description

technical field [0001] The invention relates to a method for preventing and treating tomato diseases, in particular to a method for preventing and treating tomato yellow leaf curl virus disease, and belongs to the technical field of vegetable planting. Background technique [0002] Tomato yellow leaf curl virus disease is a fulminant and devastating disease. The affected fields generally reduce yield by 20%-30%, and in severe cases, even fail. Tomato yellow leaf curl virus (Tomato yellow leaf curl virus, TYLCV) belongs to the Begomovirus genus (Begomovirus) of Geminiviridae, because this virus can only be infected by whitefly (Bemisia tabaci) under natural conditions. Persistent mode transmission, also known as whitefly-borne twin virus, is a type of plant DNA virus with twin particle morphology, which can cause devastating damage on tomato crops. Bemisia tabaci is the main carrier of tomato yellow leaf curl virus disease, and the main way to prevent the disease is to preve...
