This invention discloses a method for topping Yunyan 87 tobacco variety suitable for low-latitude, high-altitude tobacco-growing areas. The method involves transplanting tobacco plants between April 25th and May 5th, and then classifying and topping the plants according to their growth status (early flowering, poor growth, average growth, good growth, and excellent growth). Specifically, for early flowering plants, the "flowering without leaf removal" method is used, lengthening the internode distance by 5 cm and leaving 16 leaves, with the plant height controlled at 80-85 cm after topping. For plants with poor, average, good, and excellent growth, 18, 20, 22, and 24 leaves are left respectively, with plant heights controlled at 90-95 cm, 100-105 cm, 110-115 cm, and 120-125 cm. Experiments have shown that this method significantly improves tobacco yield and economic benefits, with a substantial increase in per-acre output value and the proportion of high-quality tobacco, superior to traditional topping methods. This method effectively solves the problems of unreasonable plant population structure and low tobacco yield and quality in low-latitude, high-altitude tobacco-growing areas.

Water hyacinth (Echhornia Crassipes) is an aquatic plant known as one of the most important and dangerous aquatic weeds globally. This plant has significant effects on the ecosystem and aquatic environment, causing disruptions in sea transportation and sometimes leading to the destruction of aquatic life in its habitat. Water hyacinth has led to pollution of geographical areas in many countries, recognized as an environmental problem that disrupts the food cycle, water quality, and marine industries. The destructive effects of this plant are so severe that some sociologists consider it a key factor in poverty and hindering the development of countries and the planet. Each water hyacinth plant produces about 1 liter of water waste daily, posing a serious threat to the world's fresh water resources due the millions of plants worldwide. Until today, various chemical, biological and mechanical solutions have been utilized to control this invasive plant. These strategies have not had a significant impact in some geographical areas, or on the contrary, they have had harmful effects (such as the effects of using strong herbicides) on the environment and aquatic ecosystems. Notably, many solutions have not effectively targeted the abundant and resilient seeds of water hyacinth. By utilizing biological signaling (biological messages) to promote bacterial symbiosis in water hyacinth for nitrogen fixation from the atmosphere, and spraying a solution without herbicides or strong poisons, with the aim of establishing the cycle of nitrogen fixation in the plant by inhibiting growth and or the effect on the bacterial symbiotic species in water hyacinth, the production of seeds in the plant is very little and even stopped, as well as the effects of decline and acceleration of the aging process of water hyacinth and the destruction of the plant appear. As a result, we will witness a decrease in the plant population, decrease in growth and reproduction, a significant decrease in water consumption, and a decrease in the quality of the biological tissues of the plant as a result of limiting the resources created for the water hyacinth plant. According to the investigation and study of the effects of this method on micro-organisms and macro-organisms in the water and its margins, it seems that this innovative solution by targeting the fixation of nitrogen from the air and disruption of symbiosis in water hyacinth has a significant effect and the lowest environmental risk compared to other methods.
