What situations should be prevented when growing tobacco? Premature flowering is the phenomenon where the tobacco plant flowers early before reaching the height and leaf count normal for the variety. The root cause of premature flowering is that the tobacco plant's growth is hindered while its development proceeds too quickly. Factors that lead to premature flowering include climatic drought, especially water shortage during the rapid growth period; transplanting too early, prolonged low temperatures or seedlings being too old...
What situations should be prevented when growing tobacco?
Premature flowering is the phenomenon where the tobacco plant flowers early before reaching the height and leaf count normal for the variety. The root cause of premature flowering is that the tobacco plant's growth is hindered while its development proceeds too quickly. Factors that lead to premature flowering include climatic drought, especially water shortage during the rapid growth period; transplanting too early, prolonged low temperatures or seedlings being too old; malnutrition; high soil moisture and poor drainage, etc.
The following measures should be taken to prevent premature flowering: 1. Fertilize rationally so that the tobacco plant has adequate nutrition. 2. Drain and irrigate in a timely manner. After premature flowering occurs, topping can be done in time to cultivate branch tobacco, minimizing losses as much as possible.
Bottom baking is the phenomenon where the lower leaves of the plant turn yellow prematurely or even die before they mature. There are two types of bottom baking: water baking and drought baking. Water baking is caused by insufficient light, too large a pale-colored bottom, and poor ventilation and moisture dissipation in the field; drought baking is caused by soil drought, where the nutrients and water of the lower leaves are transported to the upper leaves, causing the lower leaves themselves to lose water and suffer nutrient deficiency, thus turning yellow and dying. To prevent bottom baking, first, plant at a rational density so that ventilation and light penetration in the field are good; second, earth up at the proper time, fertilize rationally, and drain and irrigate in a timely manner; finally, harvest the bottom leaves in time.
