In the hundred vegetable garden, there are two“King vegetables”: they are large, covering more than 200 square meters of space; they bear so many fruits that during the expo, a total of more than 10,000 fruits can be produced. These two vegetables are the tomato trees in the center of the indoor exhibition area.
Entering the indoor exhibition area of the vegetable garden, many visitors will choose to have a rest under the tomato trees. Sitting in a comfortable chair, looking up to see the eyes full of small red tomatoes, like a small red lantern, such a unique landscape is not easy to enjoy.
According to Beijing Agricultural Technology Extension Station senior agronomist Li Xinxu introduced that the tomato tree's cultivation technology characteristic has three aspects.
Special production facilities and cultivation methods are needed to create suitable growth conditions for tomato trees. When cultivating tomato trees, pruning methods should be combined with soilless culture. Tomato seedlings are selected from Beijing Maoyuan Guangfa Agricultural Development Co. , Ltd. base of high-quality seedlings, in the growth of about 40 cm when transplanted to the vegetable garden.
Li Xinxu introduces, the vegetable facility that involves in tomato tree cultivation basically has fill light system and soilless culture system. Fill light system to ensure that tomato trees need to increase light, can be artificial fill light. The soilless system is hydroponic, and the tomatoes are grown in two square meters of troughs at a depth of 10 centimeters. The temperature, nutrient value and ph of the nutrient solution are precisely regulated to support the growth of the tomato tree through this delicate“Nutritional diet”.
Techniques for routine plant maintenance are different. Both to play tomato tree unlimited growth characteristics, but can not let it grow at will, to maintain a good“Body”, suitable for viewing. During this period, the tomato trees need to be cleaned, trimmed, and shaped.
Due to the long growth cycle and display cycle of tomato trees, in order to ensure a better display effect during the opening period, tomato trees were originally cultivated in advance. At that time, it was winter, and the temperature in the indoor exhibition area of the vegetable garden was relatively low. It was necessary to create suitable temperature and light conditions for the growth of tomato trees, and it was necessary to increase temperature, fill light and other technologies and corresponding auxiliary equipment.
According to Li Xinxu introduced that the tomato tree is suitable for planting in many places, because the demand is different, the cultivation site is different, the technology and the cost are not the same. For example, production greenhouses, sightseeing greenhouses, agricultural parks and so on, as long as there are corresponding facilities, can be planted, or even residents of the balcony, as long as the temperature and water and fertilizer supply to ensure that it can be.
The greatest value of tomato trees is both production, but also as a landscape for viewing, with a very strong interest. Compared with the traditional tomato cultivation method, although the cost of cultivation facilities and maintenance has been increased, it belongs to the cultivation method of high input and high output, and has a very good prospect in the industrial production of vegetables. According to Li Xinxu introduction, at present this kind of tomato“Tree-type” soilless cultivation in the suburbs of Beijing has been promoted more than 2000 MU.
