Fertilization methods for High yield of Potato

Potatoes are rich in starch, and they are the tuber vegetables that many people like to eat. Xiaobian is one of them. The amount of fertilizer needed in the whole growth period of potato is relatively large, and a more reasonable fertilization method is needed if you want to achieve high yield. But many people do not know how to fertilize and when to fertilize. So today, the editor has brought you the high-yield fertilization technology of potatoes, let's have a look!

1. Characteristics of fertilizer requirement

The demand for fertilizer in each growth stage of potato is different, but the nutritional requirements are also more comprehensive. For example, when potatoes emerge after sowing and reach the seedling stage, a large amount of nitrogen and potassium fertilizer is needed, the demand for two kinds of fertilizer is about 1 × 5 of the total, and the demand for phosphate fertilizer is small. Then the demand for potash fertilizer is the highest when it reaches the flowering and budding stage, followed by nitrogen and phosphorus fertilizer. The demand for nitrogen and phosphorus increases at the final maturity and expansion period. Therefore, when applying fertilizer, we must make a good collocation of fertilizer nutrition according to the soil fertility and the growth stage of potatoes.

2. Base fertilizer

Potatoes like a cool environment and require the soil to be fertile and loose. Because the growth period of potatoes is relatively short, a large proportion of fully mature base fertilizer should be used when fertilizing. This can effectively improve the soil planting environment and promote the emergence and growth of potatoes. Base fertilizer is the most important when fertilizing, the use of farm manure should also be properly mixed with nitrogen, phosphorus and potassium to improve the quality of potatoes. Nitrogen, phosphorus and potassium fertilizer is the basic nutrition of plant growth, ensuring adequate nutrition can make potatoes grow better and increase yield.

3. Topdressing

The high temperature and rainy environment in summer is an important time for topdressing potatoes, the first topdressing is seedling fertilizer, when 80% of the seedlings grow to 12-16 cm. Topdressing combined with ploughing and soil cultivation, topdressing fertilizer can use urea mixed with water to promote the growth of stems and leaves of the plant. The second time in the potato growth stage and tuber growth period to apply tuber fertilizer to meet the nutritional needs of potato expansion. The second fertilizer is mainly nitrogen fertilizer, and the amount of fertilizer is determined according to the growth of the plant.

4. Potash fertilizer

According to the experience of growing potatoes, potatoes have the greatest demand for potash fertilizer, because the yield of potatoes is higher, so the demand for potash fertilizer naturally increases. When potatoes are in the potato promotion period, apply corresponding potassium sulfate according to the planting area, and then do a good job of ridging and soil cultivation. And with the ploughing and weeding work together, enough potash fertilizer can significantly increase the yield of potatoes, so we can apply potash fertilizer appropriately according to the plant conditions in the planting process to increase the yield of potatoes.

The above is a brief introduction of potato fertilization methods, in fact, is the potato demand for some fertilizers, nitrogen, phosphorus and potassium as a basic nutrition is essential. However, it is also necessary to apply appropriate amounts of magnesium, calcium and other elements to ensure adequate and comprehensive nutrition in the growth of potatoes. That's all for today's introduction. This article is for reference only. I hope it can help you.
