Tourism-based, multi-vine, long-season tree-based cultivation with both production and scientific research functions has recently been successful in the Hancun River Agricultural Science and Technology Demonstration Zone in Beijing. Through this kind of tree culture, the annual tomato plant yields more than 8000, the single plant level spreads 7-9m, and the plant height can be adjusted to 2-2.5m by artificially. The shape is like a tree, so some people call it For "tomato tree". There is a kind of tropical woody plant in the world. Its fruit shape resembles tomato and its botanical name is tomato tree. The "tomato tree" we introduce is not such a woody tomato tree, but the ordinary herbaceous tomato is managed by special cultivation methods and pruning and pruning to make it resemble a tree. As early as the 1980s, Japan began to conduct research on the deep-seed cultivation of “tomato treesâ€. Scientific and technical workers in China have succeeded in deep-seed cultivation of nutrient solutions in recent years. However, the cultivation of “tomato trees†has not been successful. Reported. Because it meets its growth and development needs through controlled environmental conditions, the ultimate genetic production potential of tomatoes can be explored through this research. This will have a certain guiding significance for further improving the production level and yield of vegetables. First, infrastructure requirements 1. Suitable for urban sightseeing agricultural park. As the "tomato tree" cultivation is mainly for sightseeing purposes, it must be carried out in a high-tech urban sightseeing agriculture park. Through viewing and picking, the expected economic benefits are achieved. If there is not a certain number of tourists, the purpose of the visit and the economic benefits it deserves cannot be achieved. 2. Large-scale multi-span greenhouse with controlled temperature and light environment. The "tomato tree" requires strict environmental conditions. As the plants are up to 2-2.5m in size, the required space is relatively large and must be carried out in large, multi-span greenhouses that are spacious. The suitable temperature range for the growth is 16-28°C. It is difficult to grow below 12°C and above 32°C. Therefore, it is required that there should be heating facilities in the winter and external shade, fan and water curtain cooling facilities in the summer so that the winter temperature is not lower than 12°C and the summer temperature is not higher than 32°C. Second, the cultivation of supporting equipment 1. Nutrient solution tank (slot). For the preparation and storage of nutrient solution. Plastic cans are optional, placed on the ground or buried underground, semi-subterranean. Bricks or cement can also be used to form underground cultivation tanks, requiring tightness and no leakage. The volume of the nutrient solution tank (groove) is determined by the amount of planting. It is advisable to use 2-4 square meters per 10 "tomato trees". 2. Cultivation tank. Available bricks, cement, or made of wood, iron, PE and PVC board, etc., the general specifications to length and width ratio of 1.5:1.5:0.5, a volume of about 1 cubic meter is appropriate. It requires no water leakage and no corrosion. 3. Cultivation substrate. The cultivation substrate is a mixture supporting the root system of the plant and requires light texture, stable physical and chemical properties, good water retention and air permeability. A suitable cultivation medium is a mixture of peat and vermiculite in a volume ratio of 1:1 or a mixture of peat and perlite in a volume ratio of 2:1. Rice husk, sawdust, mushroom residue and other organic materials can also be used as a cultivation medium. 4. Liquid supply facilities. It is a supporting facility that supplies plant nutrient solution. The water tank (submersible pump or centrifugal pump) should be installed in the nutrient solution tank (tank), and the timer connected with the water pump and the power supply so that the nutrient solution can be supplied regularly. The outlet of the water pump is connected to the main liquid supply pipe, which may be an iron pipe or PVC pipe with a diameter of 2-3 cm, and the branch pipe and the drop needle are connected to it. Each tomato tree needs to have more than 16 drops for the liquid, and the drop needle is to be cultivated. Slots are evenly distributed. 5. Carcass support facilities. Since it is a herbaceous plant, plant stems cannot grow upright. Therefore, it is necessary to use a cultivating frame in combination with a wire traction to achieve the purpose of forming an ideal plant shape. The cultivation frame is made of iron pipes with a diameter of about 3-5 cm, and a 33 cm square grid is made from nylon rope at 2-2.5 m above the ground. If there is an iron wire in the greenhouse, it is not necessary to set up a cultivating rack, and the wire and the nylon rope can be directly made into a 33 cm square grid to hang the vine and support the pod. Third, cultivation techniques 1. Variety selection. The selected varieties should have the following characteristics: The hard fruit pulp type that is resistant to storage and transport, the fruit red or pink, the strong disease resistance, and the ability to resist low temperature and low light and high temperature and strong light. The suitable variety is Beijing Jia Vegetable Research Center's "Jiahong 4" and several other varieties. 2. Sowing seedlings. All seasons can be nursed, the most appropriate sowing time is in mid-July, into the plastic barrel at the end of August, planted in the cultivation tank at the beginning of October, beginning to leave the fruit at the end of January, the fruit began to turn red in April. Using warm soup soaking method, with 10% trisodium phosphate disinfection, can be used to nurse seedlings. The specific method is the same as ordinary tomato production. 3. Preparation before planting (1) Nutrient composition The formulated nutrient solution is pumped to the cultivation tank for circulation. Adjust the timer and supply the liquid once every 50min during the day. Each time the liquid supply lasts for 10min, the liquid supply will make the return tube have nutrient solution outflow. Always check the EC and pH of the liquid back and adjust it in time. The pH of the nutrient solution should be controlled at about 6.5, and the EC value should be controlled within 2.5-3.0 mS/cm. (2) Preparation of cultivation tanks. In the bottom side of the cultivation tank, two holes of 3.5 cm in diameter were drilled on each side. The inside of the tank was lined with a plastic cloth, and a PVC pipe with a diameter of 3 cm was passed through the plastic to extend the pipe 5-8 cm at the bottom hole of the tank. , 7 tube head upturned, conducive to ventilation, a tube head down, connect the drainage tube for drainage. A pair of holes with a diameter of 3 mm is drilled every 3 cm on the PVC pipe for ventilation and drainage, and is placed flat on the upper part of the plastic at the bottom of the tank. Lay 10cm thick crushed stones on the plastic, lay the surface with a layer of insect-proof nets, and then pour in the prepared cultivation medium until the cultivating trough is filled, the surface is flattened, and the plants are set aside. Be careful not to trample the substrate so as not to be too tight and not breathable. 4. Colonization. When the plant height reached 30-50cm, the plants were planted in the center of the cultivation tank. One plant per tank was planted, and roots were injured as little as possible. The depth was 5cm below the surface of the cultivation tank. Immediately after planting, the nutrient solution was poured and the water was discharged into the outlet pipe. The planting density should be in the area of ​​(7-8m) x (7-8m) per plant. 5. Post-planting management (1) Pruning. Using the multi-dry pruning method, that is to choose to stay strong and strong branches, through the traction line, so that the dendrite grows in different directions like the crown, the appropriate number of trunks when the plants reach the grid when there are 25-32 growth points, plant level up to 2m should. Afterwards, the branches and vines will be continued, and the vines will be evenly distributed on the scaffolds through traction, and the dense vines will be removed by trimming to avoid mutual obscuration. All flower spikes were removed in the early stage and it was found that the old yellow diseased leaves and the lower thin and weak branches were promptly knocked out; the lower old leaves and the yellow disease leaves were later removed. (2) Leave flowers and leave fruits. When the plants spread horizontally on the cultivator up to 4m and the number of growing points is about 500, fruit and leaves are left. In order to promote the fruit growth, bumblebees can be pollinated or sprayed with 20-40mg/kg of Baoguoning. 4-6 fruits per panicle flower. After flowering, leave two growth leaves on the top of the flower crown of the crown and remove the growth point. The growth points around the crown remain and extend around to grow. (3) Warm light management. Winter heating, so that the minimum temperature of not less than 12 °C, and often cleaning the film, increase the amount of light. During the summer high temperature season, the shade should be reduced and the temperature should be reduced. Combined with the fan and the wet curtain, the temperature of the plant canopy should not exceed 32°C. (4) Pest control. The main diseases are virus disease, leaf mold, late blight and so on. Due to the small density of colonization, the disease is not very serious, and the diseased leaves were found to be removed in time, and were prevented by fumigation with chlorothalonil. Insect pests are mainly whitefly and spotted fly. They can be equipped with insect-proof nets at the entrance vents of greenhouses and hung yellow plates in greenhouses to trap and kill pests. When the insect pests are severe in summer, a net insecticide and insecticide can be killed and killed. (5) timely harvest. Because it is a species that is resistant to storage and transportation, the fruiting period is longer. After the fruits turn red, they can be preserved on the quail for 30 days. Do not harvest them immediately to increase the sightseeing effect, and the newly transformed fruit tastes bad. When the fruit turns soft, it should be harvested in time. At this time, the flavor is the best and it has a unique mellow aroma of the tomato.
