Cultivate strong seedlings 1, bed soil preparation and disinfection will be fully cooked farmyard manure and onion and garlic vegetable garden soil mixed by 4:6 ratio sifted, formulated as seedbed bed soil, after mixing with every 1 cubic meter mixed with 250 grams of urea and 1 - 2 kg of superphosphate, plus 50 grams of carbendazim (or mancozeb) per 50 kg bed soil and 100 grams of phoxim and mix well, can play a role in bactericidal and insecticidal. The sprayer was used to spray the water so that the water content reached the level of hand-squeezing without water penetration, falling to the ground, and then distributed into the nutrition cup. 2, soaking seed disinfection and germination tomato seeds into warm water at 55 °C, constantly stirring to 25 °C, soaking for 10 minutes to remove, put in 1% potassium permanganate solution soak for 15 minutes, with a gauze bag filter, tie A good bag mouth, into the water and wash until the water becomes clear, then soaked in water at 25 °C for 4 hours, remove and drain, germination to dew, ready to broadcast. 3, sowing with a small bamboo sticks to loosen the soil in the middle of the nutrition cup, and then in the center of each nutrition cup seeded 1-2 seeds budding, covering the nutrition soil thickness of about 1 cm, and then neatly discharged in the width of the nutrition cup 12 The centimeters and the depth of 16 centimeters on the low larvae, depending on the circumstances, are covered with plastic mulch, and the cymbals are put on small bow sheds on both sides. The winter and spring planting tomatoes and the tomato planting on the early spring are covered with plastic film; the summer plants and autumn and winter plants are covered with shade nets. , plastic film, in the 1 leaf 1 heart, and time seedlings to fill the seedlings, to ensure that each nutrition cup has a healthy seedlings. 4. Seedling stage management Winter-spring planting seedlings Pay attention to prolong the light, strengthen the insulation, ventilate and ventilate, regulate the light, temperature, and humidity in the nursery protection facilities, and prevent the damping-off disease and blight. In early spring, tomato should be strengthened with heat preservation, ventilation and humidity, and prolonged light. Pay attention to avoiding rain and light during the later period. Prevent main diseases such as early and late blight and virus disease. Pay attention to shade and shelter from rain during summer seedling tomato and autumn and winter planting tomato seedlings. Cooling, dwarfing control, etc. can significantly reduce virus invasion and cultivate healthy seedlings. For intensive cultivation, replanting basal fertiliser generally uses per os of cooked chicken manure or cow dung (adds 10% phoxim 812 powder per 50 kilograms of fertilizer or 200 grams of granules in 10% granules and mixes and mixes for 7 days) 5000 kilograms. Three yuan compound fertilizer 50 kg or 50 kg of Norwegian compound fertilizer, superphosphate 20 kg. The purpose of "three ploughs and three rakes" is to achieve land-breaking, loose-breathing, and lay the foundation for stabilizing production. Prevention of seedling disease during planting For every 50kg of fixed root water, 30% of the seedling enemy 60g or 72.2% Prec 50g can be added to prevent seedling disease. The line spacing is 60 centimeters and 40 centimeters, and about 3,200 acres are planted (Gold Diamond 1 breeds 1800-2000 acres). Select the cloudy afternoon colonization, set aside enough water. Be careful not to plant after heavy rain. Fertilizer field management of field fertilizer and water should pay attention to the former control and promote the reform. Colonization to the seedling stage, appropriate loose soil, pay attention not to dry, you can use 0.2% of urea and 0.2% of potassium dihydrogen phosphate mixture for foliar dressing to promote early slow 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 acre topdressing urea and potassium sulfate 8-10 kg. Fruits of the first ear were whitish to yield, watered once every 7 days, and a mixture of 0.2% urea and 0.3% potassium dihydrogen phosphate was sprayed on the leaves to promote rapid fruit enlargement, prevent premature decline, and increase yield. When the sparse flowering and fruiting plant height is about 33 cm, the bamboo must be inserted timely and the vines must be attached. At the same time, lateral buds and pruning should be removed. Generally, the leaves below the first order fruit are removed and the middle and top leaves are preserved to prevent fruit from sunburn. 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 the above 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. In order to concentrate the supply of nutrients, in order to increase the weight of the single, increase the level of commodity. Sunny days should be selected for pruning and thinning and fruit thinning. Due to the low temperature in spring and winter and the fall of flowers in high temperatures in the fall, it is necessary to use 2,4-D within 3 days of flowering of the tomato (when the temperature is higher than 15°C, the concentration is 10 mg/l; when the temperature is lower than 15°C At a concentration of 20 mg/l, the flowers are preserved and preserved, and each flower can only be treated once. Red fruit, timely harvesting of normal winter and spring planting results, early and autumn planting results, middle or late period, 30% ethephon (15 mg/l) can be applied to the fruit surface of the ripened fruit or the fruit can be taken in a 2500 mg/l solution After soaking for 1-2 minutes, the fruits can be red-marketed after 4-6 days of treatment when the fruits are stacked in a 22-25°C hotbed.
