To ensure a high-yield and fast-growing potato crop, it is essential to select superior varieties such as Kexin No. 4, which are known for their vigorous growth and disease resistance. It is highly recommended to use virus-free seed potatoes to avoid potential infections and improve overall productivity.
When selecting seed potatoes, choose healthy ones from the spring harvest. Discard any that are diseased, rotten, or damaged. The ideal size for seed pieces is between 20 to 40 grams. For fall planting, whole potatoes weighing 25 to 50 grams are preferred. Apply 1 gram of gibberellic acid in 120 to 180 liters of water, and soak the potatoes for 15 to 20 minutes during mid-July. After soaking, place them in a shaded area to sprout naturally. Once the buds reach 1.5 to 2 cm in length, they are ready for planting.
Planting should be done in late August, ideally on days with no rain. Use shallow furrows about 8 to 10 cm deep, water them after sowing, and then cover with soil to form small mounds, approximately 8 to 10 cm high. This helps with drainage and promotes root development.
Mulching is an important step. Plant in wide and narrow rows, combining sowing with base fertilizer application. The large row spacing should be 70 to 75 cm, and the small row spacing 30 to 35 cm, with plants spaced about 20 cm apart. Spread 30 to 40 kg of potassium sulfate compound fertilizer between the two small rows. After covering the soil, the ridge height should be 5 to 6 cm and the width 60 to 70 cm. Then, cover the entire area with plastic mulch, ensuring it is tightly sealed and only 1 to 2 cm above the soil surface. After heavy rains, check and re-bury any exposed areas. Within 4 to 6 days after planting, you can start transplanting seedlings if needed.
Proper watering is crucial. Water once after the seedlings emerge, and again when the plants begin to form a canopy. From October onward, the tubers start to swell, so keep the soil consistently moist but avoid flooding. If the weather is dry, water every 7 to 10 days.
For fertilization, apply 2 to 3 square feet of organic manure and 50 to 75 kg of specialized potato fertilizer during the early growth stage. Perform hilling at the time of planting. In mid-October, during the tuber expansion phase, apply 25 to 50 kg of ammonium sulfate fertilizer and hill the plants again.
Pest control is vital. Common pests include ladybugs, beet armyworms, diamondback moths, and aphids. Use pesticides like Vegetables Farmer diluted 600 to 800 times, 2% Buck diluted 1500 to 2000 times, or 2.5% Kung Fu diluted 2000 to 2500 times, alternating between them every 7 to 10 days. From mid-September to mid-October, spray a protective agent such as 80% Mengfeiling, 8% Dasheng M45, or 58% Early Epidemic-MnZn at 600 to 800 times. If an outbreak occurs, mix 58% Ledomil, 72% Kelu, and 50% Anker at 600 to 800 times and spray every 7 to 10 days for 2 to 3 applications.
In addition to pest control, apply plant regulators during tuber formation. Spray "Tianda ~ 2116" at 750 times dilution. Repeat the application after 10 to 15 days, using the same concentration. This helps stabilize cell membranes, promote growth, and extend the growing period, leading to healthier and more productive plants.
Nutrient supplements
What is Nutrient supplements?
Nutritional supplements are preparations used to supplement nutrients that may be lacking in the body's daily diet. These formulations may be single or a combination of multiple nutrients, including but not limited to the following ingredients:
- Protein (e.g. protein powder)
- Fish oil (contains omega-3 fatty acids such as DHA)
- Various vitamins (such as vitamin A, B vitamins, vitamin C, vitamin D, vitamin E, etc.)
- Minerals (e.g. calcium, iron, zinc, selenium, etc.)
- Dietary fiber
- Other specific nutrients, such as Amino Acids, enzymes, probiotics, plant extracts, etc
The purpose of nutritional supplements is to meet the nutritional deficiencies that individuals may have due to special needs, dietary habits, digestive and absorption problems, health conditions (such as disease, pregnancy, aging, etc.) or other reasons. They are usually available in the form of tablets, capsules, oral liquids, powders, etc.
When choosing a nutritional supplement, one should consider an individual's physical condition, diet, and possible side effects. Although nutritional supplements can provide additional nutrients, it does not mean that they are a substitute for a balanced diet. The best strategy is usually to get most of your nutrients through a varied diet and use nutritional supplements when necessary under the guidance of a medical or professional. In addition, excessive consumption of certain nutritional supplements may also pose health risks, so it is recommended to consult a professional before use.
