What base fertilizer is used to fertilize potatoes

Views: 104    

Potatoes, also known as potatoes, are highly starchy tubers, and reasonable fertilization is very critical throughout the planting process. Fertilization techniques should follow the principle of mainly farmyard manure, supplemented by chemical fertilizers, with the base fertilizer as the main fertilizer and appropriate follow-up fertilizer. In simple terms, it is recommended that the basal fertilizer should be combined with phosphorus and potassium fertilizers, with the amount of fertilizer accounting for more than 2/3 of the total fertilization. For supplementary fertilizers, the fertilizers usually include potassium phosphate, urea and micronutrient fertilizers, etc. In the late stage, it is especially necessary to supplement a large amount of potassium fertilizers, which should be combined with different growth periods of potatoes. Let's learn more about the fertilization of potatoes at different stages!

1、Basic fertilizer

The application of good base fertilizer is the key to potato growth, usually accounting for more than 2/3 of the total amount of fertilizer. In the process of fertilization, fully rotted farm fertilizer should be the main, while adding a certain amount of chemical fertilizer, especially phosphorus and potassium fertilizer. It is not only good for growth and potatoes, but also can play a role in improving the physical properties of the soil. Note that the fertilizer should be applied 2 to 3 cm away from the potatoes to avoid direct contact with the seed potatoes, and do a good job of mulching measures after fertilization.

Potato planting requires timely and reasonable fertilization in conjunction with different growth periods. In the seedling stage, fertilize with nitrogen, combined with cultivation of soil in the middle of the year, and use 5-8 kg of urea per mu with water to help preserve seedlings. After the flowering of potatoes, spray 0.3~0.5% of potassium phosphate solution 50 kg per mu of leaves, if lack of nitrogen can increase 100~150 grams of urea, spray once every 10~15 days, spray 2~3 times. Potatoes should be supplemented with potassium fertilizer after caking, but not with potassium chloride, so as not to cause potato chlorosis. In addition, potatoes are more sensitive to boron, zinc, if the soil is boron or zinc deficiency, need to be supplemented in a timely manner.
