Abstract:

Abstract:Wheat production not only by the genetic characteristics of species，but also closely related to the ecological environment and cultivation measures . Scientific experiment results showed that:planting density, sowing date, nitrogen logistics, irrigation and other cultivation measures play a vital role on the high yield of wheat. Suitable planting density can improve the reproductive period of super high-yielding wheat, increase the synthesis and accumulation of photosynthetic products, coordination three factors of wheat yield and achieve super-high-yield,appropriate early seeding within suitabl sowing date of wheat can extend the time for grouting ,served to increase grain weight, increase production, The jointing stage and booting stage of Nitrogen, ears can ensure an adequate basis to raise grains and grain weight, they achieve an important reason for realization of production exceeded, irrigation amount and irrigation periods of strong gluten wheat production has significant regulatory effects.
