How to grow autumn tomatoes well? Please give detailed guidance and introduction


         Autumn tomatoes are mainly marketed around National Day, but during the autumn tomato growing period, temperatures are high, rainfall is heavy, sunlight is intense, and pests and diseases are numerous, with viral disease being the most serious. Therefore, growing autumn tomatoes well is quite difficult, but you can refer to the cultivation techniques provided by Zhongdiwang:

　　I. Autumn tomato varieties and sowing dates: At present, Xifen No. 3 performs well. Generally sow around June 20, and no later. 

　　II. Cultivating virus-free strong autumn tomato seedlings:To cultivate virus-free strong seedlings, it is necessary to adhere to the "four preventions." (1) Prevent flooding and avoid aphids. Make high beds and set up drainage ditches. Clear weeds around the area to prevent aphids from parasitizing and migrating onto the tomatoes. (2) Prevent rain and high temperatures. Set up an arch frame about 1 m high, cover it with agricultural film (with the sides lifted) and shade netting or aphid-proof gauze. (3) Prevent excessive vegetative growth. Spray paclobutrazol, and the concentration must be accurate to prevent excessive inhibition. (4) Prevent viral disease. Tomato viral disease is spread by aphids, and because it has the characteristic of showing no symptoms during the seedling stage, prevention must be the main approach. First, cover with silver-gray shade netting or special aphid-proof gauze (40 mesh) to repel aphids and block aphids; second, after the 2 cotyledons of the seedlings have flattened, apply antiviral agent No. 1 by spraying combined with irrigation to prevent viral disease. 

　　III. Autumn tomato transplanting:Transplant when the seedling age is about 20 days. Before transplanting, water first to "lure weeds," then after 4-5 days fertilize and plow the soil, form ridges and make beds. The bed width is 1.2 m, with 2 rows planted per bed, row spacing 60 cm, plant spacing 20 cm, and 5500 plants per mu. Transplanting should be done in the afternoon or on a cloudy day, and the key is to be fast: lift the soil and insert the seedling. Water immediately after planting to prevent the seedlings from wilting. 

　　IV. Autumntomatomanagement:After 3-4 days from transplanting, water again to help the seedlings recover, and hoe once every 1-2 days, hoeing 3 times in a row. On the 3rd hoeing, combine with topdressing and earth up along the cultivation rows, with the height of the earth not exceeding the height of the bed ridge. The purpose of earthing up to form ridges is to prevent watering from soaking the root crown. Otherwise, the root crown will rot. Set up stakes and guide the vines onto the stakes. Use single-stem pruning, and remove any side shoots as soon as they appear. After all fruits have set, no new leaves should be seen in the field. After flowering, apply 2,4-D at a suitable concentration to treat the flowers to ensure fruit set, and every cluster must be treated. If many fruits are retained, the fruits will be small; if few fruits are retained, the fruits will be large. In addition, prevent damage from cotton bollworm, and spray promptly when eggs hatch.
