Wheat production process to determine the reasonable application of nitrogen fertilizer, nitrogen fertilizer to achieve efficient use of resources. A field test method to study the habits of farmers (T1), optimal management 1 (T2), super high-yielding planting (T3), optimal management 2 (T4) under four different culture and management model transformation and the winter wheat grain protein yield on and Content. The results show that the optimal management of the two (T2 and T4) and the farmers used to (T1) and ultra high (T3), not only can improve the early growth stage of wheat nitrogen absorption capacity, but also significantly increased the amount of nitrogen accumulation and late growth stages; T1, T3 grain nitrogen accumulation mainly depends on the flower shoot vegetative organs before the storage of nitrogen transport, the pattern of the two optimal management to improve the coordination of nitrogen transport and flowers after flowering before its nitrogen accumulation, and obtain a higher nitrogen harvest index .
Winter wheat production process to determine the reasonable application of nitrogen efficiency of resource use, realize the nitrogen. Using field experiment method was used to study the farmers habits (T1), optimizing management 1 (T2), super-high-yeild planting (T3), optimizing management 2 (T4) four different cultivation management mode of winter wheat n uptake transshipment and grain protein yield of the content and influence. The results show that these two optimizing management (T2 and T4) and peasants habit (T1) and super-high-yeild (T3), can not only improve wheat early growth absorbing ability of nitrogen, and can obviously increase of nitrogen accumulation quantity growth anaphase; T1, T3 grain nitrogen accumulation of dancers depends on the flower of upper vegetative organs storage nitrogen transhipment, two optimizing management mode, the coordination raised before flower nitrogen transshipment and flowers, and accumulated nitrogen after itself get higher n harvest index
