Onion rot causes and performance symptoms
Onion rot is mainly due to root rot, the function of absorbing water and nutrients gradually weakened, and finally the whole plant died. The main manifestation is that the whole plant leaves yellow and withered until the last occurrence of dead trees. Rotting root is a common phenomenon in the production process of green onions, which, once it occurs, leads to a large reduction in production. The main reasons for this phenomenon are the following: 1. The weight loss is the key factor that causes the rot of the scallion roots. Due to continuous cultivation for many years, there are more pathogens in the soil, and diseases of the double pods are unavoidable. This can easily cause rot of the onion roots. 2. The roots are damaged. 3. Watering onion water pollution. 4. Herbicide damage. 5. Water accumulation roots. Onion leaves have low water transpiration, weak water absorption capacity in roots, less water consumption, and less moisture. If the water is flooded during the growing period, it will make the green onion fields accumulate disasters and produce roots, dry tips, yellow leaves and dead seedlings.
