1, sowing quality: in the clay, sowing too deep, poor soil permeability, will affect the bud germination.
2. Seed coating agent injury: When the old irons coat themselves, the amount of drug is large and the coating is not uniform, which may easily cause damage to the embryo or radicle and affect normal development.
3, fertilizer burning seedlings: species, fertilizer simulcast, did not do a good job, it is easy to burn buds or burning root.
4, low temperature and high humidity: low temperature after sowing, soil moisture is too large, poor air permeability, affect the normal differentiation of buds and roots.
5, underground pests: the early ground pests eat buds or roots, resulting in the seeds can not grow properly.
6. Herbicide injury: Improper application period, large dose or sandy soil permeability, will lead to liquid infiltration, affect the normal development of buds and roots.
7. Seed freeze injury: The hybrids did not dry in time after being harvested, suffered freezing damage at low temperature, and suffered frostbite radicles or germs, resulting in failure to develop normally.
8. Injury to the seeds: During the seed production process, the embryos or radicles are damaged by the apparatus, so that the buds or roots do not germinate normally.
Corn rootless shoot prevention method
1, pick seeds before sowing, drying seeds, ensure seed vigor. Must use seed coating agent to prevent the underground pests, but must control the amount of drug coating, and to ensure uniform coating.
2, according to soil moisture control sowing depth, humidity, broadcast two fingers; humidity is small, broadcast three fingers.
3, soil moisture greater land, it is recommended to late broadcast, in case of heavy rain after sowing, timely discharge of water from the field.
