How is the European Shield tomato planted? Euro Shield is the name of the latest tomato variety introduced by American companies. Euro Shield is an infinite growth type that is resistant to storage and transportation. The fruit is pink and nearly round. And this variety has excellent merchandise, good performance and strong vitality. Let's learn about the cultivation techniques of Ou Duan tomato in summer.
1. Choose the right variety
(1) Selection requirements After many experiments and demonstrations, it can be concluded that in order to successfully complete the summer cultivation of tomato, the selected varieties must meet the characteristics of high yield and thick skin, and are suitable for transportation, high temperature resistance, anti-virus, most Red wants to have a strong ability to achieve fruit in a row.
(2) Variety introduction
The fruit of the European Shield tomato is pink and similar to a high circle. The transverse diameter of the fruit is close to the longitudinal diameter and the size is equal. The weight of the single fruit is usually between 200 and 240 g. The flesh is thick; the peel has no green shoulder, no green skin, and hardness. Good, not easy to crack, special transport, long shelf life, can be stored for up to 30 days; vitality, continuous fruit set, good fruit rate of more than 97%; anti-viral ability, low temperature resistance, so suitable It is cultivated in the early spring, after the autumn, and in the summer.
2. Shed processing
(1) Clear shed: first shed film, then remove other crops or weeds
(2) Soil disinfection: Spread the fully decomposed farmyard manure on the surface of the soil, and then mix the soil with 2kg of carbendazim. Finally, the soil was turned deep by 30cm.
(3) Air disinfection: firstly close the greenhouse. For the greenhouse of bamboo and wood skeleton, use 5 to 8 kg of sulfur powder per 667 m2, mix it with straw and sawdust, stack them separately every 10 meters, and ignite with fire. After leaving in time, wait for 2 to 3 days of processing time to achieve the effect of air disinfection.
3. Cultivation of strong seedlings
According to the conditions of the facility and the cultivation area, the appropriate sowing date and sowing amount are selected. The Shandong area is usually planted at the beginning of April. The seedling age is about 42 days, and the physiological seedling age is preferably 4 or 5 pieces; the average is about 2400 per 667 m2. Granules, and ensure that the number of planting seedlings reached 2,100; the seedling method that can be used is to use seedlings without soil seedlings or directly purchase the seedlings cultivated by the factory.
4. Preparation before colonization
(1) Proper selection and use of base fertilizer
About 5,000 kg of farmland fertilizer, about 25 kg of diammonium phosphate, about 18 kg of German red calcium sulfate, and 50 kg of organic superphosphate.
(2) Site preparation: evenly apply manure and perform deep turning. If the original production line spacing is too large ridge can be made according to the original production line spacing for good drainage on a flat ridge cultivation, poor drainage on the ridge pedestal. The number of cultivation was controlled at 2,100 plants per 667 m2.
(3) planting time, density, methods: planting time in mid-May; planting density of 2,100 per 667m2 planting; planting method is good after planting seedlings, wherein the spacing is calculated, while gracefully lump seedlings, the seedlings lump eliminate lice were placed under the spiritual roots of a sustained-release tablets of pest control. If fertile Po with fertilizer, it is blended into about 180 times irrigated planting position, casing immediately after water penetration, to ensure that the casing is higher than 1 ~ 2cm nutrient medium, followed by water, until drenched up.
5. Post-plant management
(1) Temperature: Because it is cultivated in summer, the weather is hot and the temperature is high, so it is necessary to pay attention to cooling work at any time. Make sure that the temperature is between 25 and 28 °C during the day and between 15 and 19 °C in the middle of the night. Try to keep the temperature difference between day and night between 12 and 18 °C. On the other hand, it is also possible to take different measures depending on the weather conditions, such as sliding small water on the ground, increasing the air discharge space, installing a sunshade net, and the like.
(2) Water and fertilizer: In summer, the water is easy to be lost. Therefore, you should remember to replenish water at any time after planting, but you should not over-water the water. When watering, 2.5kg Wodibao will be applied with water to keep the soil moist. After 10 days, the remaining 2.5kg of Wardibao will be applied with water.
(3) Hanging vines, pruning: When the height of the plant exceeds 30cm, hang the vines in time and remove the side branches at any time.
(4) Spraying flowers and leaving fruits: When the plants enter the flowering stage, when there are 3 flowers in the tomato inflorescence, immediately remove the first flower, and then add a proper amount of advertising red with a No. 2 Shenyang Agricultural University high-yield agent. 1kg blended with water, before ten o'clock disposable stencil printing swelling fruit. If the number of continuous fruit set is not enough, you can spray more than one liquid at the time of flower cracking. On the other hand, remember to ensure that each plant has 4, 5 ears of preserved fruit, and remove the flower front leaves and other diseased fruit, small fruit and deformed fruit.
(5) Pest control: 1 early blight: 20% Tianke 1500 times liquid, 70% product run 500-600 times liquid, 50% Anke 1000 times liquid, Doppong long 800 times liquid; once a week, continuous use 3 ~ 4 times; 2 nights of disease: 80% of the big 500 times liquid, 70% of the product 500-600 times liquid, 50% of the toxic manganese zinc 600 times liquid, more 70% chlorothalonil 600 times liquid, 64% antivirus 矾 liquid Once a week, once every 3 to 4 times; 3 leaf mold: 50% Kai 1000 times liquid, 40% Baike 1500 times liquid, 40% Shi Jiale 1000 times liquid; once a week; 4 gray mold disease: prevention Mildew 600 times solution, 20% spring leimycin 600 times solution, 47% plus ruin 600 times solution; once a week, once every 3 to 4 times.
