Walking into the planting greenhouse of Shanghai Nongrui Ecological Agriculture Development Co., Ltd. located in Hengzhao Village, Jinshanwei Town, the tomato vines are full of fruits, and the golden tomatoes are bright and full, which is very beautiful. Pick one and put it in your mouth, sweet and glutinous, delicious and juicy, and the fragrance of tomato makes people have an endless aftertaste.
At present, after the refined cultivation of aerosol cultivation technology, the small tomatoes planted by Lu Dongsheng, the person in charge of Shanghai Nongrui Ecological Agriculture Development Co., Ltd., have ushered in a bumper harvest. "After several years of technology precipitation and iterative upgrading, the small tomatoes cultivated through aerosol cultivation are of higher quality and have high trace element content, especially vitamin C, which is 2-3 times that of traditional tomatoes. Lu Dongsheng said.
"My concern is not that there are too few fruits on the vine, but too much! Because the nutrients are sufficient and the growth is good, the flowers and fruits must be strictly thinned every year to ensure that the quality of the products is controllable. Lu Dongsheng said that although the small tomatoes in the planting greenhouse are now ushering in a bumper harvest, according to his production standards, only 25 small tomatoes need to be kept on each fruit ear, and then further fruit thinning will be carried out, "so that the best quality can be obtained, and it can be listed one after another this week." ”
At present, the planting greenhouse mainly grows watermelon, small tomato, large tomato three kinds of fruits, through the research and development and application of aeroponic cultivation technology, the integration of water and fertilizer has been realized. In recent years, due to the continuous research and improvement of equipment systems, the planting base has basically realized the "one-person control" of "digital planting", "low cost, zero pesticide residues, high density and high quality". Lu Dongsheng said.
Not only small tomatoes, but this year, the watermelon planting at the base is also expected to usher in a bumper yield. Through the precise control in the early stage, Lu Dongsheng strictly thinned the fruit and screened, and only one watermelon was retained on each melon vine, and the watermelon varieties such as Xiaoguan, Xiaolan, and 8424 are currently growing well, and the fastest is expected to be available in May this year.
"We have formed a set of standardized processes for watermelon planting, and the whole process can be automatically controlled through digital technology. Lu Dongsheng said, "In the next stage, we want to work the standardization of nutrient solutions and trace elements to improve the scientific and technological efficiency of agriculture." ”
