Original title: New cultivation model can increase the sugar content of tomatoes by 60%
In the past 20 years, the group has carried out a more systematic study on the cultivation technique and physiology of high-sugar tomatoes, and for the first time in China has determined the limited root cultivation and loss-making irrigation control techniques of tomato yield and quality, and increased the soluble solids from 5% to more than 8%. This paper establishes a high-sugar tomato cultivation model suitable for China's national conditions, and conducts a study on the influence of 8 agronomic factors, such as fruit varieties, water, fertilizer and hormones, on the formation of quality and aromatic substances, and expounds the mechanism of the formation of aromatic substances in vegetable fruits, which provides a theoretical basis for high-quality tomato production.
" high-sugar tomato cultivation model has achieved four important innovations: the establishment of a root-limiting groove system, the innovation of three-dimensional model of irrigation, the capture of key technologies of nutrient liquid regulation, the development of direct use of groundwater nutrition solution, so that the cultivation cost is lower, the first 'yield and quality balance' of high-sugar tomato cultivation model. Liu Mingchi said.
it is learned that the study by the National Natural Science Foundation, the State Science and Technology Support, the Ministry of Agriculture industry projects, the Beijing Natural Science Foundation and other projects, has been the National Invention Patent 3. At present, all the equipment and varieties of this cultivation system developed by the subject have been domesticated, and the cost is only about 50% of the advanced cultivation system abroad.
