What to Do About Rotting Bean Sprouts? Detailed Cause Analysis and Solutions

Sprouts are one of the traditional vegetables that people in China love to eat, and the most common one in our daily lives is bean sprouts. There are many varieties, and during the growing process, bean sprouts can develop rot, causing huge losses to bean sprout yields. So how should rotting bean sprouts be dealt with? Let's take a detailed look together.

1. Bean seeds carrying pathogens

Before planting, because the selection of bean seeds was not strict, bean seeds carrying pathogens were used. During the growing process, these pathogens multiply rapidly in suitable environments, causing bean sprouts to rot.

Solution: Carefully select bean seeds, choosing plump, disease-free seeds. During seed soaking, carefully remove diseased insect-damaged seeds, shriveled seeds, broken seeds and other inferior bean seeds. Then wash the seeds with a low-concentration bleaching powder and limewater solution. Hot water can also be used to scald the seeds. This can kill the pathogens on the surface of the bean seeds, improve the vigor of the bean seeds, and increase the germination rate.

2. Containers not strictly disinfected

Just like bean sprouts carrying pathogens, the containers used for cultivation are also quite important. If strict disinfection measures have not been taken, pathogens will also invade during planting, causing bean sprouts to rot.

Solution: Cultivation containers must undergo strict disinfection measures. Before planting, in addition to keeping tools and containers clean and sanitary, they must also be strictly disinfected before use. They should be washed and disinfected with a low-concentration bleaching powder solution or alum solution.

3. Temperature too high or too low

Temperature is the most important factor in growing bean sprouts. If the temperature is too high or too low during the bean sprout growth period, it will cause them to rot.

Solution: The suitable growth temperature for bean sprouts is between 20-25 degrees. After planting, when sprouting, the most suitable temperature is 18 degrees. After sprouting, the temperature should be appropriately raised to around 23 degrees. Within this temperature range, they grow extremely quickly and rot can also be reduced.

4. Water quality not clean

Besides temperature, the next thing is water management. Bean sprouts differ from other crops in that they only need water to grow normally. During the growing process, they need sufficient water. However, if watering is not timely, causing the bean sprouts to lack water, or if the water quality is not clean, these situations will cause them to rot.

Solution: It is recommended to use clean well water or stream water. It is strictly forbidden to use unclean river water or pond water. Well water and stream water are clean and free of pollution, and are warm in winter and cool in summer, which helps bean sprouts grow. Watering must be done at fixed times and in fixed amounts, generally once every 5 hours, to wash away metabolic waste.

The above is an introduction to the causes of rotting bean sprouts and the solutions. We hope it can help you. If you want to learn more related knowledge, please stay tuned to us.
