Using the functional special-purpose fertilizer of fused mass granulating humic acids can significantly increase Protein content in the wheat, effectively improves wheat quality.
3.2 different fertilization is to the influence of wet wheat gluten content
Fig. 3 different fertilization is to the influence of wet wheat gluten content
After wet gluten is wheat-flour dough flush away starch, the elastoplasticity material that obtains, it is made up of gliadine and glutenin.Wet gluten is an important indicator weighing wheat quality, and the quality of wheat quality depends primarily on the content and the quality of gluten, and it had both reflected the nutritional quality shape of wheat, reflected its processing quality shape again.
Can know by Fig. 3, use the content that the functional special-purpose fertilizer of fused mass granulating humic acids can significantly increase wet gluten in the wheat.Compare with the T1 processing, the wet gluten content that T2 handles raises 6.72%, handles with T3 and compares, the wet gluten content rising 6.37% that T4 handles.
3.3 different fertilization is to the influence of wheat yield
The yield per unit of wheat is reconstituted by unit surface spike number, number of grain per ear and grain.Within the specific limits, output is along with the increase of unit surface spike number improves.Spike number is too much, and number of grain per ear reduces, and grain heavily descends, and output also reduces.Therefore, only under the situation that the three coordinates each other, could obtain high yield.
