What are the control measures for root burn in bean sprouts?
There are many varieties of bean sprouts, and they are relatively comprehensive in nutrition. They are a common vegetable in our daily lives. However, during bean sprout production, root burn can occur, often causing all the bean sprouts in the whole jar to rot and resulting in huge losses. So how should root burn in bean sprouts be prevented and controlled? Let's take a look together.
1. Select good seeds
When planting, choose fresh seeds with no mold for growing. Before planting, the seeds must undergo strict treatment to remove mixed grains, diseased and insect-damaged grains, and inferior seeds. Then put the seeds into hot water at 60 degrees for 1-2 minutes. Rinse with clean water until they return to room temperature, or soak them in a low-concentration bleaching powder and limewater solution for 2-3 minutes. Both methods can achieve the purpose of disinfection and sterilization, can kill pathogenic bacteria on the surface of the bean seeds, improve the germination rate, and reduce the possibility of root burn.
2. Clean containers and tools
Just like the bean seeds, the containers and tools used for growing must also undergo strict disinfection and sterilization treatment, so as to prevent pathogens from invading and causing root burn. In addition, after each batch is taken out of the jar, wash it once with clean water, and use it after sun exposure for sterilization. If there is a phenomenon of rotten sprouts, also disinfect the containers and tools with limewater before use.
3. Keep water quality clean
Growing bean sprouts cannot be done without water. Bean sprouts do not need soil to grow. As long as there is sufficient moisture, they can grow normally. However, water quality is also a key point. If the water quality is not clean, it can also cause root burn in bean sprouts. In addition, attention should also be paid to the water quality used for soaking seeds and cleaning before planting. It is not advisable to use river water or pond water, so as to avoid bacterial infection. It is recommended to use tap water. When watering during growing, it is recommended to use well water, because well water is warm in winter and cool in summer, which can speed up the growth of bean sprouts.
4. Temperature regulation
The suitable temperature for the growth of bean sprouts is 20-25 degrees. It must not be too high or too low. The temperature must be stable and should not fluctuate suddenly. This is not conducive to the growth of bean sprouts, and in severe cases it can also lead to root burn and rotten sprouts. When the temperature is too low, close doors and windows, pour warm water, or cover with film and use other methods to raise the temperature; when the temperature is too high, remove the film in time, pour some low-temperature water, and strengthen ventilation to lower the temperature.
