First, nurture strong seedlings to ensure that the whole seedling 1, bed soil preparation and disinfection will be fully cooked farmyard fertilizer and vegetable garden soil mixed in accordance with the ratio of 4:6 sieve, formulated as seedbed soil, after mixing with every cubic meter and then mixed with 250 grams 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 bactericidal insecticide. The sprayer was used to spray the water so that the water content reached the level of hand-squeezing without water leakage, falling to the ground, and then distributed into the nutrition cup. 2, soaking germination germination tomato seeds into warm water 55 °C, stirring constantly to 25 °C, soaking for 10 minutes, placed in 1% potassium permanganate solution soak for 15 minutes, with a gauze bag filter, tie a good bag mouth Into the water, 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, timely sowing with a small bamboo stick to loosen the soil in the middle of the nutrition cup, and then each of the nutrition cup central seeded 1-2 seeds germinated, covered with a nutritious soil thickness of about 1 cm, and then the nutrition cup neatly discharged in the width of 12 cm Depending on the condition, the depth of 16 cm deep, depending on the circumstances, is covered with a plastic film, and the small bow sheds are placed on both sides. The tomato and early spring tomatoes are covered with plastic film and straw; the summer plants and autumn and winter plants are covered with tomatoes. Shade net, plastic film, in the 1 leaf 1 heart, and time seedlings to fill the seedlings, to ensure that every nutrition cup has a healthy seedlings. 4. Seedling 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 and dwarfing control can significantly reduce virus invasion and cultivate healthy seedlings. Second, intensive cultivation, replanting basal manure commonly used per mus of chicken manure or cow dung (every 50 kg of fertilizer by adding 10% phoxim 812 powder or 10% grain full of granules 200 g mix, buckle film 7 days) 5000 Kg, 50 kg of ternary compound fertilizer or 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. 3. Prevention of seedling diseases during planting Each 3kg of fixed root water can be supplemented with 30% of the seedling enemy 60g or 72.2% Prec 50g to prevent seedling disease. Line spacing is 60 centimeters and 40 centimeters, and about 3,200 acres are planted. Select the cloudy afternoon colonization, set aside enough water. Be careful not to plant after heavy rain. Fourth, the field of fertilizer and water management, pay attention to the former control in the promotion after the attack and colonization 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 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 the first ear was whitened to the garden, 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. . Fifth, timely sparse blossoms and fruit thinning, prompting the tomato fruit to grow vigorously When the plant height is about 33 cm, it must be timely inserted bamboo, binding vines, while removing lateral buds, pruning, generally remove the leaves below the first order, retain the middle and top Leaves to protect against sunburn. There are the following types of single pruning, pruning, dry pruning, and double dry pruning. The pruning can be determined according to the planting density using three different methods, one or two of which 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, dredging 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 rate of commodity. Pay attention to the selection of sunny days for pruning and thinning and fruit thinning. Low temperature in spring and winter and fall in high temperature in fall, should use 2,4-d within 3 days of flowering in tomato (When the temperature is higher than 15°C, the concentration is 10 mg/L; when the temperature is lower than 15°C, the concentration For 20 mg/litre, the flowers are preserved and each flower can only be treated once. Sixth, the fruit red early maturing varieties generally winter and spring planting results early and autumn and winter planting results can be used in the middle and late 30% ethephon 2000 (15 mg / l) coated fruit fruit surface or peeled fruit in 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.
