Tobacco topping time and method steps

When planting tobacco, topping is needed, which can control the growth advantage of the top, promote the timely distribution of nutrients to each leaf, and make the upper leaves fully mature, thus improving the quality and yield of tobacco leaves. The topping height of tobacco should be suitable, which is generally determined according to variety characteristics, climate conditions, soil fertility, planting density and cultivation conditions. There are 19-20 tobacco leaves when topping, and 2-3 more when growing vigorously. The growth rate of tobacco is still relatively fast, so many new leaves can be produced one week after topping.

When will tobacco be capped?

The topping time of tobacco should be in the morning and evening, and the timely topping method should be flexibly mastered according to the climatic conditions, soil fertility, fertilization level and tobacco plant growth. If the conditions are right, you can top it, but if you don't grow well, you can't top it.

Tobacco topping method steps

When topping tobacco, it is usually done on sunny days. The position of topping depends on the growth and fertility of the field. After it blooms, fireworks and two flower protection leaves are removed. If it grows vigorously, you can only destroy the fireworks and keep the flower protection leaves.

Problems needing attention in tobacco topping

1. When topping tobacco, it is best to beat the disease-free tobacco plants first, and then the disease-free tobacco plants to avoid contact and infection. And take the damaged stamens out of the field to prevent the spread of the disease. 2. When topping tobacco, it should be done on a sunny day after dewdrops are dried, so as to facilitate wound healing and reduce the chance of disease transmission. 3. When topping tobacco, 2-3 leaflets on flower branches should be removed at the same time, leaving about 1-2 top stems to meet the demand of top leaves for nutrients and water.
