High yield potato fertilization technology

China's Hebei, Gansu, and Northeast China are high yield areas for potatoes. Taking Gansu as an example, the area of ​​Gansu sowing potatoes is about 20,000 hectares every year. Every year, 65% of the commodity potatoes are exported to the south and coastal areas. High-quality potatoes have become an important factor for local farmers to get rid of poverty and promote local economic development. engineering. To get good quality potatoes, we must manage fertilization rationally.
1, Shizujifei: potato fertilizer is mainly based on fertilizer, generally accounting for 60% to 70% of the total fertilizer. The basal fertilizer is applied in combination with soil preparation or soil covering. After planting, 2 to 3 tons of stubble fertilizer is planted per acre. At the same time, 50% of the total amount of nitrogen fertilizer, 40% of potash and phosphate fertilizer (all phosphate fertilizers are used as basal fertilizer) and 2 bags of golden treasure microbes After the bacterial fertilizers were mixed, the strips were applied to the manure and then soiled. It is an ideal potato organic fertilizer and cover material because it has a wide range of sources, convenient materials, and complete nutrients. Note that it is necessary to use a good fermented manure, if the fermentation is not good, it will carry out "secondary fermentation" in the soil and will carry germs, affecting the growth of potatoes. It is best to use Fermentation Fertilizer Fermentation Fermentation. Fermentation and decomposed manure is safer and more effective.
2, early application of top dressing: nitrogen fertilizer in the top dressing should not be too late in the early application, especially in the late, in order to avoid the stem and leaf length and affect the tuber enlargement and quality. In the middle and late period, potassium fertilizer is mainly used together with the golden baby microbial fertilizer. When the seedlings are planted, they are topdressed for the first time, promote early-onset growth, and increase the area for photosynthesis. Top dressing is best avoided at noon, should be carried out in the afternoon, it is best to ditch, should avoid fertilizer on the leaves, if fertilizer is spread immediately after the application of fertilizer should be watered to speed up fertilizer dissolution, taking into account the cleaning of the leaves.
3. Appropriate root dressing: potatoes require large amounts of calcium, magnesium, sulfur and other elements, in order to improve the quality, can be combined with pest control outside the root dressing.
