First, nurture strong seedlings 1. Bed soil preparation and disinfection: The fully cooked farmyard manure and onions and garlic vegetable garden soil are mixed and sifted at a ratio of 4:6 to be formulated as seedbed soil, and then mixed with 250 m2 per square meter. Gram of urea and 1-2 kilograms of superphosphate, plus 50 grams of carbendazim (or mancozeb) and 100 grams of phoxim and 50 kg of bed soil, can play a role in sterilization, insecticide. Spray the water with a sprayer so that the water content reaches a point where the water is squeezed into a group and does not seep through to the ground, and then it is distributed into the nutrition cup. 2, soaking disinfection, germination: the tomato seeds into the warm water at 55 °C, stirring constantly to 25 °C, soaking for 10 minutes to remove, put in 1% potassium permanganate solution soak for 15 minutes, filtered with a gauze pocket, Put a good bag mouth, into the water and wash until the water becomes clear, then soaked in 25 °C water for 4 hours, remove and drain, germination to dew, ready to broadcast. 3. Seeding: Loosen the soil in the middle of the nutrition cup with a small bamboo stick, then sow 1-2 seeds of germination seeds in the center of each nutrition cup, cover the nutrient soil to a thickness of about 1 cm, and then neatly discharge the nutrition cup to a width of 12 cm. The depth of 16 cm deep, depending on the circumstances, and then covered with plastic film, on both sides of a small arch truss, winter and spring tomato planted plastic film and grasshoppers: autumn and winter tomatoes covered shade net, plastic film, in 1 leaf 1 At the time of heart and time, the seedlings will be planted to ensure that each nutrient cup has a seedling. 4, the management of seedling period: winter and spring planting seedlings pay attention to prolong the light, strengthen insulation, ventilation and humidity, regulate the light, temperature, humidity in the nursery protection facilities, the main prevention of damping-off disease, blight. Second, intensive cultivation, reuse basal fertilizer: generally per acre Shi cooked chicken manure or cow dung (every 50 kg of fertilizer by adding 10% phoxim 812 powder or 10% granules full of 200 grams of granules mix well, buckle film for 7 days) 5000 kg, 50 kg of compound fertilizer, 50 kg of Norwegian compound fertilizer, and 20 kg of superphosphate. The purpose of "three ploughs and three rakes" is to achieve land-breaking, loose-breathing, and lay the foundation for stabilizing production. Third, the prevention of seedling disease when planting: Each 50 kilograms of fixed root water can be added 30% of the seedling enemy 60 grams or 72.2% Prec 50 grams, to prevent seedling disease. Line spacing 60 cm 40 cm, about 3200 plants per acre. Select the cloudy afternoon colonization, set aside enough water. Be careful not to plant after heavy rain. Fourth, the field of water and fertilizer management attention before the control in the promotion of attack: planting to the seedling period, appropriate loose soil, pay attention not to dry, can be used 0.2% of urea and 0.2% potassium dihydrogen phosphate mixture for foliar fertilizer promotion Slow early seedlings. When the seedlings of the first inflorescence are inflated, they are followed by 1-2 times of dilute feces to raise the seedlings and take a shelf of high yield. The walnuts from the first ear fruit to the fourth ear fruit have just bloomed as a fruit period, paying attention to the heavy dressing (with nitrogen fertilizer). And mainly potassium fertilizer), re-sprayed fruit water, every 10 days per mu recovery urea and potassium sulfate 8-10 kg. The fruit of each ear fruit was white to the garden, watered once every 7 days, and 0.2% urea and 0.3% potassium dihydrogen phosphate were sprayed on the leaves to promote rapid fruit enlargement, prevent premature aging, and increase yield. . Fifth, timely sparse fruit thinning, to promote the fruit of the tomato Wang Liang: When the plant height is about 33 cm, timely insert bamboo, binding vines, while removing lateral buds, pruning, generally the first order of the following leaves removed, retaining the middle and The top leaves protect against sunburn by masking fruit. There are the following pruning: single dry pruning, pruning dry half pruning, double dry pruning, pruning can be determined according to the planting density using 3 different methods, one or two of them can also be used. Early-maturing and self-sealing tomato varieties are generally concentrated in fruit set, and the fruits are too small. It is necessary to carry out sparse flowering and fruit thinning during full bloom or full fruiting period. The number of controlled fruit per plant is about 40, and when the fruit of each ear is large, for example, broad beans, leave 3-4. A good fruit, dredged excess flowers and fruits and deformed fruit, so that the nutrient concentrated supply, in order to increase the weight of a single fruit and improve the fruit. To select a sunny day for pruning and thinning and fruit thinning. Due to low temperatures in spring and winter, it is necessary to use 2,4-D within 3 days of tomato flowering (10 mg/l when the temperature is higher than 15°C; 20 mg/l when the temperature is lower than 15°C) ) The flowers are preserved and preserved. Each flower can only be processed once. Sixth, the fruit redness: the general winter and spring planting results in the early and autumn and winter planting results can be used in the middle and late 30% of the ethephon 200015 mg / l smear the fruit surface of the ripe fruit or the fruit is soaked in 2500 mg / l solution soaking 1- In 2 minutes, the fruits can be red-marketed after the fruits are placed in a 22-25°C hotbed for 4-6 days. VII. Pest control: The major diseases of tomato are bacterial wilt, virus disease, and fungal diseases.
