Effect Of Fertilizing Model On Wheat Yield And Quality Of Variety Changhan58

In order to study the high fertilizing efficiency on dryland wheat and its effect on grain yield and quality, author set different fertilizing level to understand how to increase wheat yield and grain quality with highly efficient fertilizing model. From 2012 to 2014 in Jujia town of Changwu Shaanxi, using wheat variety Changhan 58, the author set 5 different fertilizing level trials, then survey wheat yield, yield construction and analysis grain quality, to study the effect of fertilizing model on wheat yield and quality of variety Changhan58. Results show that:1. Yield of fertilizing trails are significantly higher than control. The second, third and fourth trial’s mean yield of two years has growth rate of 7.2%, 4.9% and 9.9% than control. the fifth trial has the max growth rate of 24.5%; compared with farmer’s level(second trial), the third, fourth and fifth trail has increased respectively-2.1%, 2.5% and 15.6% in two years. Yield construction of different fertilizing level differ significantly and spike increased significantly. The second, third, fourth and fifth trial’s mean yield of two years has growth rate of 17.0%, 13.5%, 23.2% and 27.4%; the third, fourth and fifth trial’s mean spike of two years increase at-2.9%,-10.1% and 9.1% than farmer’s level. Grains per spike of different fertilizing level differ significantly, the second, third, fourth and fifth trial’s mean yield of two years has growth rate of 0.2%,-6.1%,-3.5% and 4.1% than control; the third, fourth and fifth trial’s mean spike of two years increase at-6.3%,-3.7% and 4.3% than farmer’s level. Kernel weight of different fertilizing level differ significantly: the second, third, fourth and fifth trial’s mean yield of two years has growth rate of-4.1%,-0.8%, 0.2% and-1.3% than control; the third, fourth and fifth trial’s mean spike of two years increase at 0.4%, 1.4% and-0.2% than farmer’s level.2. Different fertilizing level has no significantly effect on grain hardness, flour yield, tough development time, stability time, evaluation value, FQN, max resistance and stretch area, but has significantly effect on protein content, sedimentation value, softening degree and extensibility. The second, third, fourth and fifth trial’s protein content increase at 11.6%, 6.6%, 10.1% and 10.4% than control; the third, fourth and fifth trial’s protein content increase at-4.5%,-1.3% and-1.3% than farmer’s level. The second, third, fourth and fifth trial’s sedimentation value increase at 13.4%, 4.5%, 14.4% and 25.5% than control; the third, fourth and fifth trial’s sedimentation increase at-7.8%, 0.8% and 10.7% than farmer’s level. The second, third, fourth and fifth trial’s softening degree increase at-4.1%,-7.8%,-13.0 and-15.9% than control; the third, fourth and fifth trial’s softening degree increase at-3.9%,-9.4% and-12.8% than farmer’s level. The second, third, fourth and fifth trial’s extensibility increase at 4.2%, 7.9%, 2.5% and 1.0% than control; the third, fourth and fifth trial’s extensibility increase at 3.6%,-1.6% and-3.0% than farmer’s level.
