After the seeds are planted, over time it will be found that the seeds underground will sometimes rot, which is caused by many reasons.
Tillage caused by buds. Long-term flooding after sowing results in low temperature and hypoxia, resulting in poor hair roots and budding sheaths, forming plowing and budding. In addition, the serious damage caused by drum mudworms can also cause plowing and plowing. The prevention method is to insist on humid management in the bud period and prevent early irrigation. Drum mud insects can be boiled with 20 pounds of dried tea per acre before sowing and boiled, then splashed with water and applied to the noodles.
Caused by pathogenic bacteria. Long-term low temperature and rain, the viability of seed buds is reduced, and the growth of roots is stagnant, which causes the infection of microbial pathogens such as Pythium and rotten buds. To prevent rotten shoots, we must pay attention to improving the quality of the field preparation, seize the cold tail and warm the head to sow, and adhere to the early wet management.
Toxic substances. The application of fresh organic fertilizer or grass and moss coverings in the rice field. In the case of long-term rainy weather or large-scale water accumulation, the organic matter rots to produce toxic substances that cause the seed buds to die. This phenomenon is more serious when the rain turns over after the rain. The remedy is to irrigate the horse to wash the poison and decontaminate in time, and then ventilate in the field.
