The seed nursery machine can cultivate the tobacco seedlings well, but you still need to manage them in the later period to increase the tobacco yield.

Temperature management is the key to ensuring neat and healthy growth of tobacco seedlings. After the tobacco seeds are sown in the greenhouse, under the sealed and insulated condition of greenhouse, the sowing area must be covered with a film.
It takes about 10-15 days for the tobacco seedlings to grow neatly from the sowing. The temperature in the film should not exceed 30 ℃, and it is best to keep it within 25-28 ℃.
When the temperature is lower than 10 ° C, from 10am to 2pm every day, it is necessary to observe the temperature in the green, especially the temperature of the small arch shed. If necessary, you should adjust it to the proper temperature.
If the temperature is higher than 10 ° C, observe the temperature in the greenhouse from 8am to 3pm.
If the temperature is lower than 13 ℃ for a long time, the greenhouse must be insulated and warmed. Generally, there are two ways to improve the temperature including covering the greenhouse and heating inside greenhouse. When the seed nursery machine works in the greenhouse, we generally adopt the later heating way. Ignite the refractory and put it in the greenhouse. The temperature should keep above 18 ° C.
If the temperature in the greenhouse exceeds 30%, you should ventilate and dehumidify in a timely manner. If the fog is heavy or the temperature is low with rainy weather for a long time, even if the temperature in the shed is lower than 18%, you still need to properly ventilate. During continuous rainy days, it is better to ventilate for 1-2 hours at noon every 2 days.
Tobacco leaf cutting
Disinfection of leaf cutting tool
The disinfection solution can be 10% to 30% bleach powder, or 150 times of 2% chlorine dioxide. After using the agent, the blade must be washed with clean water. The disinfection of the electric leaf cutter is to soak in the disinfection solution for more than 3 minutes.
When the tobacco seedlings grow for about 35 days with 5-6 true leaves, it is time to cut some of the leaves. The blade is 3-4 cm away from the top bud, and the leaves are cut by 1/3. In addition, it needs to be trimmed 3-5 times before transplanting.
After the tobacco seedlings reach 5 true leaves, the greenhouse film should be opened to keep insect nets, strengthen the light and ventilation, and make the tobacco seedlings completely contact the external environment. If the temperature is higher in the late seedling period, you shall ventilate greenhouse day and night. In addition, you need to drain the nutrient solution 10 days before transplanting without watering or fertilizing.
