From April to May in spring, the weather is warmer and the ground temperature is rising. It is also the season of sowing in one year. If the seeding skills are not well mastered, it will cause rotten sprouts. When planting, pay attention to the following matters:
First, the main causes of bad species are:
(1) Immersion germination is poor and the quality of the seed buds is poor;
(2) Excessive soil moisture, sowing too deep, resulting in silt seed rotten species;
(3) The soil is too hard, the seeds are exposed, causing water shortage and drying; or due to the heavy rain after sowing, the seed buds are exposed, causing bad species.
The main methods for preventing rotten seedlings are to improve germination quality and sowing quality, and to take remedial measures against the causes of rotten seeds. If the seeds are exposed, they should promptly make up the covering to promote emergence, and serious replanting should be done in time.
Second, although the seeds can germinate after sowing, but the phenomenon that has not yet reached the point of death is called rotten buds. The main causes of bad shoots are: 1 Ploughing: The long-term flooding after sowing, resulting in a low-temperature and oxygen-deficient environment, resulting in poor hair roots, buds and elongated shoots, the formation of ploughing buds. In addition, underground pests (flea and earthworms) are seriously endangered and can also cause plowing. The prevention method is to insist on the moist management of the buds to prevent early irrigation. The hazard of underground pests is to use 50% phoxim EC at 1500g per hectare mixed fine sand or 375-450kg fine soil, and then open the shallow ditch next to the roots to pour the medicine soil, then cover the soil, or combine the soil into the soil, which can prevent Several types of underground pests. Especially when winter wheat returns to green or spring planting seedlings suffer from cockroaches or worms, it can be remedied by this method. 2 long-term rain, pathogenic bacteria cause bad shoots. With long-term low temperature and rain, the vitality of seed buds decreased, and the growth of roots stagnated. As a result, microorganisms such as Pythium bacteria infested the shoots. To prevent rotten buds, we must pay attention to improving the quality of soil preparation, rush to sow cold head warming, and adhere to pre-wet management. 3 Poisonous substances cause bad shoots: The soil is treated with fresh organic fertilizer or covered with grass and moss. In case of long-term rainy weather or ground water, organic matter will rot and produce toxic substances, which will kill buds. This phenomenon will turn cloudy after rainy weather. The performance was even worse. The remedy is to timely infuse horse water to decontaminate and remove the ventilation.
