Embodiment 1

[0025] A cultivation method for controlling tomato yellow leaf curl virus disease, specifically:

[0026] Seedlings were raised on June 9, 2019, planted on July 10, 4 leaves and 1 heart were planted, with a large row spacing of 80cm and a small row spacing of 50cm, 667m 2 2000 plants were planted. On the day after planting, irrigate the roots with Sifenghuan aqueous solution with a mass concentration of 0.01%, 200ml per plant;

[0027] The Sifenghuan aqueous solution with a mass concentration of 0.01% is prepared by adding water to 50% Sifenghuan wet seed dressing agent.

[0028] Delay hanging seedlings. Before hanging seedlings, let the plants lie down and climb on the ground without cutting branches. Before hanging seedlings, water every 2-6 days to keep the ground moist, that is, the relative moisture content of the 10cm soil layer is not less than 75 %;

[0029] When the main stem of the plant grows 1 spike of fruit and 2 spikes of flowers, that is, when the trunk of th...

Embodiment 2

[0040] A cultivation method for controlling tomato yellow leaf curl virus disease, specifically:

[0041] Seedlings were raised on June 25, 2020, planted on July 22, 4 leaves and 1 heart were planted, with a large row spacing of 100cm and a small row spacing of 70cm, 667m 2 2000 plants were planted. On the day after planting, use 0.02% Sifenghuan aqueous solution to irrigate the roots, 150ml per plant;

[0042] The Sifenghuan aqueous solution with a mass concentration of 0.02% is prepared by adding water to 50% Sifenghuan wet seed dressing agent.

[0043] Delay hanging seedlings. Before hanging seedlings, let the plants lie down and climb on the ground without cutting branches. Before hanging seedlings, water every 2-6 days to keep the ground moist, that is, the relative moisture content of the 10cm soil layer is not less than 75 %;

[0044] When the main stem of the plant grows 1 spike of fruit and 2 spikes of flowers, that is, when the trunk of the plant has 16 leaves and...

Abstract

The invention discloses a cultivation method for controlling tomato yellow leaf curl virus, which comprises the following steps: using tomato seedlings which are not resistant to yellow leaf curl virus, performing field planting when four leaves and one core exist, and irrigating roots with 0.01-0.02% (mass concentration) Silatrane aqueous solution on the same day after field planting; delaying seedling hanging and conducting watering once every 2-6 days before seedling hanging; and when the trunk of each plant has 16 leaves and 1 core, starting to hang seedlings, and spraying 60 mg/kg chitosan oligosaccharide aqueous solution on the leaf surfaces on the seedling hanging day. According to the cultivation method, the morbidity of the yellow leaf curl virus of infected tomato varieties is reduced from 56.8%-61.6% to 3.5%-4.1%; the soluble solid content of tomatoes can reach 4.5%-5.2%; and the single plant yield of the tomatoes can reach 4.81-5.28 kg.

Description

technical field [0001] The invention relates to a cultivation method for controlling tomato yellow leaf curl virus disease, and belongs to the technical field of vegetable pest control. Background technique [0002] At present, yellow leaf curl virus disease has become the main obstacle to tomato cultivation in solar greenhouse in autumn and winter. Varieties resistant to yellow leaf curl virus are usually used to control the outbreak of autumn and winter tomatoes in solar greenhouses, but the varieties resistant to yellow leaf curl virus are often of poor quality, especially poor "taste". How to control non-resistant tomato yellow leaf curl virus disease will become the key factor for the success of high-quality cultivation of autumn and winter tomatoes in solar greenhouses. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cultivation method for controlling tomato yellow leaf curl virus disease, which can effe...
