Nitrogen fertilizer plays an important role in the growth of potato. After the application of nitrogen fertilizer, the growth of stems and leaves is lush, the color is dark green, and the effect of increasing production is very obvious. So some people have a preference for nitrogen fertilizer. When one mentions increasing fertilizer, it means increasing nitrogen fertilizer. In some places, the land is already very fat, but when it is used in potato, it still uses a large amount of urea. The application rate is 50 kg per 667 square meters (1 mu), and the amount of pure nitrogen is as much as 23 kg. As a result, the seedlings are pushed high. Very big, top-heavy, lodging serious, stems and leaves spread to more than 30 centimeters thick on the ground, the lower leaves do not see the sun is not breathable, there will be rot, and the underground stem tubers late, the tubers are tender, the low starch content will affect the total Yield, nitrogen fertilizer can not be applied too much when planting potatoes.
