How to Grow Potatoes for High Yield? A Detailed Guide to the Latest Cultivation Techniques
The potato is the most commonly eaten potato in our daily lives, and its planting area in our country is very large. When growing potatoes, people focus more on the yield of the potatoes, because yield directly affects the planting benefits of farmers. So now many people are trying every possible way to increase potato yield. So how should potatoes be grown to achieve high yield? Below, the editor will give you a brief introduction. Let's take a look together!
1. Plot selection
Potatoes cannot be grown in continuous cropping, so when choosing a plot for potato planting, we must first ensure that the previous three crops in the plot were not potatoes or other Solanaceae crops. If potatoes are grown continuously, they are extremely prone to various soil-borne diseases, which will have a serious impact on their yield, let alone high yield. The harm to the soil is also very great, causing soil nutrient loss, especially various trace elements. If potato growth lacks trace elements, then not only will the yield be low, but the quality will also become very poor. Therefore, they should be rotated with crops such as wheat.
2. Soil preparation
The main edible part of the potato is the tuber. Potato tuber growth requires loose soil with sufficient fertility. So if we want high potato yield, then after selecting the land, we must do a good job of soil preparation. The potato planting plot should choose soil with normal drainage and irrigation, a thick plow layer, and a soft texture. Then after the previous crop is harvested, deeply plow the soil and make beds ready for planting. Control the width of the beds according to the terrain of the plot and the soil moisture content. If the terrain is high and drainage and irrigation are good, then wider beds can be made appropriately; otherwise, narrow beds should be made.
3. Scientific fertilization
Potato growth has a high demand for nutrients, so we must do a good job of fertilization. During soil preparation, apply it together with base fertilizer. The base fertilizer should mainly be decomposed farmyard manure, combined with an appropriate amount of superphosphate, plant ash, and other fertilizers, applied in holes below the 10 cm soil layer. Then we should do a good job of topdressing according to the growth of the potatoes. After emergence, apply a sprout and seedling fertilizer once to promote seedling growth. Then at the bud stage, apply a tuber-setting fertilizer once, and control the amount of fertilizer according to plant growth. Generally, it is not suitable to apply more fertilizer after flowering.
4. Thinning and final singling of seedlings
After most potato seedlings have emerged, do a good job of thinning and final singling of seedlings. After full emergence, remove weak seedlings and keep strong ones. At the first thinning, keep about 5 seedlings per hole. Then at the second thinning, reduce it to about 3 seedlings. Before transplanting, spray an appropriate amount of diluted new high-fat film on the seedlings, which can effectively improve the survival rate of seedling transplanting. When the plants grow to about 30 cm, appropriately spray some Diguo Zhuangtiling, once every other week, about 3 times, to provide sufficient nutrition for potato growth.
The above is a brief introduction to how to grow potatoes for high yield. If you want high potato yield, you must do a good job in management, strengthen the prevention and control of pests and diseases, and ensure normal potato growth. That is all for today's introduction. This article is for reference only, and I hope it can be helpful to everyone.
