What are the effects of fertilization on wheat?

Everyone knows that wheat is a crop that requires a lot of fertilizer. It is also necessary to apply a lot of fertilizers when it is planted during the cultivation of wheat. What effect does fertilization have on wheat?

Effect of Nitrogen on Wheat

Nitrogen is the main factor affecting wheat quality. Within a certain range, the grain protein content increased with the increase of nitrogen application rate. The effect of nitrogen application time on the protein content of wheat grain was greater than the yield. Basically, the protein content gradually increased with the delay of the fertilization period. Both nitrogen topdressing time and method have a significant effect on the formation of wheat yield and quality. Under the same nitrogen application rate, postponing nitrogen application at the top-dressing stage and filling stage can enhance the ability of nitrogen metabolism and transformation in the later growth stage, and it is beneficial to increase wheat yield. Yield and improve nutritional quality and processing quality. Nitrogen application rate can significantly increase the content and output of dry and wet gluten, and with the delay of nitrogen application period, the dry and wet gluten content will gradually increase, which will have a good effect on increasing the content of dry and wet gluten. However, it is not always the case that the later the better, the most important factor is the application of nitrogen at flowering stage.

Effect of phosphorus on wheat

Maintaining a soil available phosphorus content of 22-30 mg/kg is very important for ensuring the high yield and quality of wheat. Phosphorus application had no adverse effect on nitrogen metabolism and grain protein. Phosphorus spraying has a good effect on the grain quality of wheat, but due to the excessive increase in yield due to phosphorus application, nitrogen is diluted in grains, which may reduce the protein content. In addition to being a nutrient that promotes the growth of crop roots, phosphorus plays an important role in enhancing wheat drought resistance. The combination of nitrogen and phosphorus has a greater effect on increasing wheat yield and improving quality, and is an important way to high yield and quality.

Effect of Potassium on Wheat

Potassium has a significant effect on wheat yield and quality. Potassium application can increase yield and improve quality. The use of potash fertilizer can improve the quality of wheat products. In the case of long-term application of organic fertilizer, the application of potash fertilizer can improve the processing quality of flour, but there must be sufficient supply of nitrogen and phosphorus to show good results, because potassium application promotes Absorption of nitrogen, if nitrogen is insufficient, does not function well as potassium. In short, balanced fertilization is a key measure for high yield, quality and efficiency of wheat.

The above is the introduction of the effect of fertilization on wheat. Friends who cultivate wheat can understand and apply fertilizers more rationally.
