Nitrogen fertilizer is used skillfully, economically and efficiently.
First, the effect of nitrogen conservation is good. Changing nitrogen fertilizer from surface application to deep application can greatly reduce the volatilization loss and denitrification of nitrogen fertilizer. Reduce the consumption of fertilizer by weeds and algae, so that the nitrogen fertilizer has a good effect on nitrogen conservation. The nitrogen fertilizer was deeply applied to 7ml / 5cm. According to the determination, ammonium bicarbonate ball fertilizer was applied deeply, and the nitrogen loss was 3% 30 days after fertilization.

The proportion of nitrogen, phosphorus and potassium applied to potatoes should be appropriate.
The demand for nitrogen, phosphorus and potassium in potato is equally important. In the process of yield formation, nitrogen supply is the basis to ensure the formation of sufficient green leaf area for photosynthesis; phosphorus supply is also indispensable for tuber formation and starch accumulation; on the basis of sufficient nitrogen and phosphorus, potassium supply is necessary for carbohydrate assimilation in the early stage, aboveground to underground tuber transportation and starch accumulation in the later stage. The field test showed that the absorption ratio of nitrogen, phosphorus and potassium in potato was about 1 ∶ 0.5 ∶ 2.5.
