Reasons for the poor emergence of maize seedlings

① low temperature or heavy rain: experiments show that low temperature will reduce the germination rate or germination energy of seeds. Too much Rain Water will hinder the normal respiration of seeds and easily cause seeds to be infected by mold and cause rotten seeds. ② extensive soil preparation or improper application of fertilizer: bumpy grains, uneven land, uneven soil moisture or different sowing depth will affect the normal germination of seeds. When sowing, too much fertilizer, uneven distribution, or seeds in direct contact with fertilizer will burn out the buds. ③ interplanting is too early: wheat field interplanting is too early, the symbiotic period of wheat and corn is too long, and it is easy to form weak seedlings. ④ seeder problem: the seeder is careless and unskilled to the planter, resulting in missed seeding. ⑤ underground insect harm: mainly small land tiger harm, bite off buds, resulting in lack of seedlings and broken ridges. ⑥ drug damage: when mixing seeds with chemicals, overdose or uneven seed mixing will result in drug damage.
