Effect of different farming methods on dry matter accumulation of dry land wheat after blooming.

Yield of wheat was not steady and high in hill drylands in the central areas of Sichuan due to water deficit.The dry matter accumulation and physiological index of dry land wheat after blooming was studied through different farming methods.The results showed the planting method of 2 m stripe width was the highest yield model of wheat in hill dry-lands, the yield of interplanting was higher than that of all-planting,and the wheat yield of planar method was higher than that of ridgy method . In order to achieve high-yield of wheat,the increase of dry matter accumulation and filling rate of wheat after blooming were key factors.
