Apply enough base fertilizer. Potato fertilization is based on base fertilizer, which generally accounts for 70% to 80% of total fertilization. The base fertilizer is often applied in combination with organic fertilizer and chemical fertilizer, and is applied in combination with soil preparation or soil covering. The base fertilizer is based on the application of 2500-3000 kg of high-quality organic fertilizer per acre, and the 60-80 kg of Schulsi series compound fertilizer.
Apply seed fertilizer as appropriate. When the base fertilizer is insufficient or the cultivated land is too late to fertilize, it is often used for planting, and 15 to 20 kilograms of special compound fertilizer is applied as the seed fertilizer. The application of seed fertilizer is mainly carried out by means of ditch application or acupoint application, but the fertilizer should not be in direct contact with the seed potato to avoid burning the seed potato.
Apply fertilizer early. Nitrogen fertilizer should not be too late in topdressing, especially in the later stage, to avoid the growth of stems and leaves and affect tuber swelling and quality. In the middle and late period, potassium fertilizer is the main application. It can be divided into 2 to 3 applications. When the seedlings are used, the first top dressing is carried out to promote early growth and increase the photosynthesis area. At this time, nitrogen fertilizer accounts for 30% of the nitrogen application rate, and potassium fertilizer accounts for 20% of the total potassium application rate. At the time of the bud, the second top dressing is carried out to promote the continuous growth of the stems and leaves, and increase the area of ​​photosynthesis, which is conducive to the expansion of the tuber.
Appropriate root dressing. Potatoes have a relatively large demand for micronutrients such as calcium, magnesium, sulfur, boron, zinc, etc. Therefore, it is necessary to combine external soil fertility conditions and potato growth conditions, and timely external fertilization (generally referred to as foliar fertilization) to Improve potato resistance and yield. From the time when the potato seedlings began to spread, every 7 to 10 days, the leaves were topped with 0.1% magnesium sulfate, 0.3% potassium dihydrogen phosphate, 1000 times triacontanol mixture, sprayed 3 to 5 times, evenly sprayed. Wet blades.
Supplement magnesium fertilizer. During the rapid expansion of potato underground tubers, each plant is applied with 50-60 grams of magnesium sulfate, applied with clear water or decomposed manure, or digging shallow trenches around the plants to promote rapid expansion of underground tubers.
Avoid applying chlorine fertilizer. Potato is a chlorine-free crop. Do not apply potassium chloride or compound fertilizer containing chloride ions. Rational fertilization is a prerequisite for high yield and stable yield of potato.

The body produces carnitine in the liver and kidneys and stores it in the skeletal muscles, heart, brain, and other tissues. But its production may not meet the needs under certain conditions such as increased energy demands and therefore it is considered a onditionally essential nutriention. There are two forms (isomers) of carnitine, viz. L-carnitine and D-carnitine, and only the L-isomer is biologically active.
