Partial application of nitrogen fertilizer in summer corn


The application of nitrogen fertilizer to summer maize, wild summer corn, and vegetative growth, the formation of carbohydrates for the synthesis of proteins, the reduction of fiber and lignin formation, the underdevelopment of the mechanical organization of stems and leaves, stems soft, easy Collapsed, and delayed flowering.

It is easy to infect the insects with excessive nitrogen application. The soluble nitrogen of maize plants increased, the cell protoplasm was rich, the cell wall became thin, the leaves drooped, the air and light were poor between groups, and the air humidity was high, which was conducive to the occurrence of pests and diseases. Reduced pest and disease ability.

Affecting the absorption of trace elements by crops and reducing the ammonium and ammonium carbamide in fertilized nitrogen fertilizers, the bicarbonate produced by decomposition will seriously affect the absorption of zinc by maize. For example, if nitrogen fertilizer is applied when the corn seedlings are stiff, the stiff seedlings will become stiffer; if there is too much nitrogen in the soil and rainy weather occurs during the pollen period, the starch stored in the pollen grains will be significantly reduced, resulting in poor fertilization and increase in grain size.

Destruction of soil structure Nitrogen fertilizers do not contain organic matter and do not have the effect of improving soils; single application and long-term large-scale application of nitrogen fertilizers will gradually compact the soil and cause soil pH to change.

Electric Heating Cape is quite similar to Electric Over Blanket. Their main difference is the shape. Heating cape is more like a clothes.

People can wear it during a cold night, and choosing the suitable heat setting to keep warm, as it has adjustable 4 temperature settings.

Heating cape is also not suggested to be used during sleeping.

It also has the function of automatic shut off, normally it is set up by 2 hours, which is approved to be the best for human health.
