Causes of and Solutions for Spontaneous Bud Rot in Yellow Soybean Sprouts and Mung Bean Sprouts: Why Does Sprouting Lead to Rot

Sprouts are one of the traditional vegetables that people in China love to eat. The most common one in our daily lives is bean sprouts. There are many varieties, and during the cultivation of bean sprouts, bud rot can occur, causing huge losses to bean sprout yields. So how should bean sprout bud rot be solved? Let's take a look at the detailed introduction below.

1. The bean seeds carry pathogens

Before planting, because the selection of bean seeds was not strict, bean seeds carrying pathogens were used. During the cultivation process, these pathogens multiply rapidly under suitable conditions, causing bud rot in bean sprouts.

Solution: Carefully select bean seeds, choosing plump, disease-free bean 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 lime water 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 are not strictly disinfected

Just like bean sprouts carrying pathogens, the containers used for cultivation are also quite important. If strict disinfection measures are not carried out, pathogens will also invade during cultivation, causing bean sprout bud rot.

Solution: Cultivation containers must undergo strict disinfection measures. Before planting, in addition to keeping tools and containers clean and sanitary, strict disinfection must also be carried out before use. A low-concentration bleaching powder solution or alum solution should be used for washing and disinfection.

3. Temperature is 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 bud rot.

Solution: The suitable temperature for bean sprout growth 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, it grows extremely quickly and can also reduce bud rot.

4. Water quality is not clean

In addition to temperature, the next factor is water management. Bean sprouts are different from other crops. They only need water to grow normally. During the growth process, they need sufficient water. However, if watering is not timely, causing bean sprouts to lack water, or if the water quality is not clean, both will lead to bud 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 pollution-free, and are warm in winter and cool in summer, which helps bean sprout growth. Watering must be done at fixed times and in fixed amounts, generally once every 5 hours, to wash away metabolic waste.
