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.

This invention relates to a double-pruning method for fresh broad beans, belonging to the field of broad bean cultivation technology. The method includes six major steps: first-season planting, first-season harvesting, first pruning, second-season management, second pruning, and second-season harvesting. This invention breaks the notion that fresh broad beans can only be harvested once per planting, and overcomes the technical challenge of enabling summer-planted broad beans in mid-altitude areas south of the Yangtze River, represented by Yunnan, to produce a second crop of pods, thus allowing for the harvesting of two crop seasons. It innovates a planting method for summer-sown fresh broad beans that involves two pruning stages: pruning the branches and topping. Within the same growth period, it increases the yield of fresh pods in the second season while ensuring the first season's yield. The combined yield of fresh pods in both seasons reaches a maximum of 2285.54 kg / mu, with a total output value of 17107.98 yuan / mu. This represents a new high in both actual fresh pod yield and output value, achieving maximum economic benefits on limited land.
