1. Variety selection Organic organic substrate cultivation has no strict requirements for the selection of tomato varieties. It is necessary to select high-yield, disease-resistant and good-quality varieties according to the local residents' consumption habits. At present, large-size hair powder 802, Zhongza No. 9, Jiafen 15, Zhongshe No. 4 and so on are used in production. 2. The construction of the cultivation bed and the filling of the matrix are followed by digging the trough in a north-south direction, with an inner diameter of 0.48 m and a depth of 0.15 m. The bottom of the tank is covered with a layer of plastic film and the soil is isolated. The tank is filled with 2 to 3 cubic meters of matrix. The ratio of the matrix is ​​peat: slag = 4:6. Each cubic metre of the substrate before mixing is to be mixed with 5 kg of solid organic fertilizer and 1.5 kg of ternary compound fertilizer. 3. Cultivation season and cornice arrangement Organic ecological substrate cultivation Tomatoes can be grown in greenhouses and plastic greenhouses, and can be cultivated in early spring, late autumn and winter. Early spring sowing in late January sowing, planting in late March; late autumn late sowing seedlings in late July, planting in early September; winter and spring in late November sowing nursery, planting in late December. 4. The drip irrigation system adopts the natural pressure drip irrigation of the storage tank. An independent storage tank is built in a single booth. The length of the pool is 4 meters, the width is 1.5 meters, and the height is 2 meters. The floor of the pool should be 0.5 meters above the ground level. In order to prevent shading and take up too much planted area, the pool should be built along the greenhouse or the gable wall. The drip irrigation belts in the main pipe and cultivation tank in the shed can use plastic pipes and troughs to lay two dropper pipes, and a layer of 0.1 mm thick narrow plastic film is coated on the drip pipe belt to prevent drip irrigation from spraying and evaporating. 5. Nursery and colonization using artificial soilless plug breeding methods. The substrate for the nursery was mixed with peat and vermiculite at a volume ratio of 2:1, and then 10 kg of dried chicken manure was mixed with 1 m3 of mixed matrix and mixed well. The substrate was drenched with water and sowed after the water was soaked. One seed per hole, dried seeds were broadcast directly, and 0.5 cm thick seedling substrate was covered after sowing. The pre-emergence temperature is maintained at 25 to 30°C, and the temperature after emergence is 20 to 25°C during the day and 10 to 15°C at night. Seedlings should be kept moist. Growing 3 to 4 leaves can be planted and planted for about 30 days. Before planting, the cultivation substrate was leveled and leveled, and water was poured 1 times to fully absorb the matrix. After the water seepage, 2 rows of pits were planted in each trough, so that the substrate was slightly higher than the shoot height, the plant spacing was 30cm, and 3000 plants were planted per acre. After pouring small water. 6. Field management 1 temperature after planting. During the growth of tomato, the temperature in the room kept 21 to 24°C during the day, and the exhalation began when the temperature exceeded 27°C; the temperature was 16 to 18°C ​​during the night. It is possible to maintain a higher temperature for 5 hours after sunset and a lower temperature for the latter half of the night. 2 fertilizer and water management. After planting, water was poured for 1 day in 5 days to keep the rhizosphere matrix moist. The fruit is poured into the log, and it is usually poured on a sunny day for 30 minutes. Little or no pouring on cloudy days. According to the number of preserved fruit spikes and planting density of the tomato, generally 3 to 5 spikes need to be topdressed 4 to 6 times. Mostly during fruit enlargement, top dressing is performed once every 10 to 15 days. Each cubic meter of substrate is topped with 1.5 kg of sterilized chicken manure plus 0.5 kg of compound fertilizer (14% nitrogen, 10% phosphorus, 14% potassium, 4% calcium, 9% magnesium, 6% sulfur, 2% iron, and manganese, Trace elements such as copper, molybdenum and boron). Fertilizer should be evenly scattered 5cm from the root, with water infiltration into the matrix. 3 plant adjustments. After the tomato flowering results, the plants were supported by a plastic rope hanging method. The pruning method uses single dry pruning to reduce pests and increase yield. Usually 3 to 4 per ear fruit. The old leaves, diseased leaves, and the lower leaves of mature fruits were promptly removed and taken out for outdoor treatment. After the general fall, it retains 6 to 7 ear tips, and leaves 8 to 10 ear tips in early spring or winter and spring. 4 pollination. Non-pollution tomato production generally does not use hormone treatment. Artificial pollination or insect-assisted pollination is used. Artificial pollination pollination was performed every day from 10 am to 11 am after flowering. Insect-assisted pollination uses honeybee pollination. 5 fruit bagging. After the fruit is set, the fruit is determined by sparsely flowering and fruit thinning, and the bag length is 220mm, width is 160mm, thickness is 0.08mm, and the product is a colorless transparent polyethylene film bag. The film bag is placed over the fruit, and the film bag mouth is tied together with a string on the shank, but it should not be too tight to prevent the lateral growth of the pedicel, while maintaining a certain degree of ventilation. Fruits can be listed together with bags. The fruit bagging prevents the pesticides from being directly sprayed onto the fruit and is not listed at the safe interval after being absorbed by the fruit epidermis. 7. Diseases and pests prevention is mainly based on agricultural control and biological control, supplemented by chemical control. When using chemical control, select low-toxicity and low-residue pesticides, and pay attention to the safe use interval to ensure that the product is not contaminated by pesticides. 8. After the harvested fruit enters the green ripening period, the harvesting is appropriate when the top begins to turn orange.
