Using Special functional melt granulated humic acid fertilizer can significantly increase the content of protein in wheat, effectively improves wheat quality.
The impact of 3.2 different fertilization on wet wheat gluten content
The impact of Fig. 3 different fertilization on wet wheat gluten content
Wet gluten is that wheat flour dough washes away after starch, the elastic-plastic materials obtaining, and 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 content and the quality of gluten, and the nutritional quality shape that it had both reflected wheat, reflects again its processing quality shape.
As shown in Figure 3, use Special functional melt granulated humic acid fertilizer and can significantly increase the content of wet gluten in wheat.Compared with processing with T1, the wet gluten content that T2 processes raises 6.72%, and compared with processing with T3, the wet gluten content that T4 processes raises 6.37%.
The impact of 3.3 different fertilization on 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 declines, and output also reduces.Therefore, only, in the situation that three coordinates mutually, could obtain high yield.
The impact of table 1 different fertilization on wheat yield and constituent element thereof
| Process | Grain number per spike (individual/fringe) | Thousand seed weight (g) | Hectare spike number (ten thousand/hm 2) | Output (kg/hm 2) |
