What situations should be prevented from growing tobacco? Early flowering is the phenomenon that tobacco plants bloom ahead of time because they do not reach the height and number of leaves that the varieties should have grown normally. The root cause of early flowering is that the growth of tobacco plant is blocked and develops too fast. The factors leading to early flowering are dry climate, especially lack of water in prosperous period, early transplanting, long-term low temperature or long seedling age, malnutrition, high soil moisture, poor drainage and so on. The following measures should be taken to prevent early flowering: 1. Reasonable fertilization should be taken to make tobacco plants nutritious. 2. Timely drainage and irrigation. After the occurrence of early flowering, we can top and cultivate branch tobacco in time to reduce the loss as much as possible. Bottom drying is the phenomenon that the lower leaves of the plant yellowed ahead of time and even died before they were mature. There are two kinds of bottom drying: water drying and dry drying. Water drying is caused by lack of light, excessive light bottom, poor ventilation and humidity in the field; dry drying is soil drought, and nutrients and water in the lower leaves are transported upward, resulting in their own loss of water and nutrient deficiency and yellowing and death. To prevent bottom drying, first of all, reasonable close planting should be made to make the field well ventilated and transparent; secondly, timely soil cultivation, reasonable fertilization, timely drainage and irrigation should be done; finally, foot leaves should be harvested in time.
