In recent years, Shaanxi, Shandong and other provinces agricultural sector, according to the characteristics of local wheat sowing agronomic, developed a dryland wheat sowing fertilizer, after a large area test to promote and promote the sowing of agronomic wheat sowing, a significant increase in yield. Shaanxi Province, Baoji, Xianyang, Weinan three (city) to promote the technology of wheat dry gully sowing for several years in the amount of 200 to 300 kg per mu, sowing than the traditional method of yield 30% to 60%. First, the wheat dry trenching sowing growth reasons 1. Sowing quality Sowing, opener to the surface of the open-leaved seed, sowing in the wet soil, but also reduce the surface floating and sowing too weak species, the emergence rate
