Essentials of Potato Fertilization Techniques

With the adjustment of the planting structure, more and more farmers are planting potatoes. However, due to the impact of traditional fertilization, only fertilizer and diammonium are used as the bottom fertilizer on potato fertilization, and no top dressing is used. The average amount of fertilizer used by northern potatoes is (pure) 10 kg / mu nitrogen, 5 kg / mu phosphorous, 5 kg / mu potassium, converted to 300 kg of urea, 150 kg of 64% diammonium, and 50% sulfuric acid. 150 kg of potassium. To obtain high-quality and high-yield potatoes, the following fertilizers should be used as fertilizers in the planting process:

1. Base fertilizer. The base fertilizer is applied with high-quality farm manure combined with chemical fertilizer. All the farm manure and phosphate fertilizer, 50% nitrogen fertilizer, and 70% potassium fertilizer are used as the base fertilizer. The method of fertilization is furrow or hole application before planting, and the fertilization depth is 15 cm.

2. Topdressing. Topdressing is divided into two times: â‘  Protect seedlings after the seedlings are promoted to promote the growth of stems and leaves. The amount of fertilizer applied is 2/3 of the remaining nitrogen. â‘¡ Promote potato fertilizer before the plant is planted and at the stage of potato setting. The dosage is: 1/3 nitrogen fertilizer and 30% potassium fertilizer. Fertilization method: Strip application or hole application, 10 cm in depth to prevent fertilizer loss.

Potatoes are more sensitive to zinc fertilizer and boron fertilizer. You can spray zinc and boron fertilizer by foliar spray, 50-70 kg of fertilizer solution per mu, spray once every 7 days, spray 2-3 times.
