Suitable distance between wheat seeds and fertilizer during mechanical sowing

To determine the suitable distance between wheat seeds and fertilizer during mechanical sowing, the seed-fertilizer distance experiments were carried out. The results show that the wheat seeds that were mixed with medium and high amount fertilizer were injured seriously and germination rate, seedling growth and wheat yield were also influenced. In the case of under-fertilization and lateral fertilization, with the distance getting nearer, the germination rate, seedling growth and wheat yield were more significantly affected. In conclusion, the suitable distance is 6 cm in the underside fertilization and it is 4～6 cm in the lateral fertilization.
