Fengmin Tonghe technical experts teach you how to grow potatoes:
First, the plots of land for potato cultivation are selected to be loose and fertile, with deep soil layers, water-drainage and drought-irrigation, and sandy soil. Neutral or slightly acidic flat and gentle slope plots are most suitable. Such plots alone can provide more nutrients for potatoes.
The process of land preparation is mainly deep turning and rolling. Deep plunge to reach 20-25cm. In places where the spring drought is serious, whether in spring or autumn, they should follow the pressure of turning and pushing, so that the land is flat, the soil is fine, and the deficiency is real. In areas with high soil moisture, besides deep turning and rolling, ridges should also be provided in order to protect the earth and increase the temperature of the ground. When ridging, it should be according to the predetermined line spacing, spacing, to make a good foundation for sowing.
Second, seed potato preparation
1. After selecting a good variety for the seed potato, select high quality seed potato. Remove the frozen, rotten, diseased, wounded, and wilt tubers, and select the juvenile potatoes with neat tubers, smooth, soft and fresh skin.
2. Seed Potato Processing (1) Dangerous Species: The seed potatoes that have been carefully selected after being sent out are packed in sacks or plastic mesh bags or stacked in empty house cargo warehouses, so that the temperature is maintained at 10 to 15°C and there is scattered light. . After about 15 days, when the buds just sprouted to see the small white bud, they could cut and sow the seeds.
(2) Shaizhong: The seed potatoes are placed in a sunny place as far as possible to maintain the temperature of the trapped species, and they are frequently turned. When the potato skin is green, it can be cut.
3. The cutting bud test showed that the weight of each bud was best reached one or two, and the minimum was not less than 30 grams. Using Mongolian Tripitaka Microbiological Fertilizer Compound Bacteria 2.4 kg seed dressing 150 kg - 170 kg, can play Seedling Qi, budding strong effect. Buds best with the cut with the sowing, can not be stacked for too long, if a few days after the cut and then broadcast, often cause heat within the bud eye pile, such a piece of potato after the emergence of seedlings are not prosperous, thin yellow, susceptible to period of potato Viral disease, but also easy to rot, affect the seedlings.
3. Fertilization (Fengmin Tonghe Fine Fertilizer Spray Fertilizer, Foliar Fertilizer to Help You Solve Worries)
Potatoes have high requirements for fertilizers. In particular, virus-free potatoes have a strong growth potential. They have strong absorption and great potential for yield increase. They must apply good fertilizers to ensure the supply of nutrients. Every 2000 pounds of potato production requires 5 kilograms of pure nitrogen, 2 kilograms of phosphorus pentoxide, 11 kilograms of potassium oxide, and sufficient potassium for the entire growing season. The proportion of fertilizer required for potato high-yielding was obtained from the Potato District of Tangshan, Hebei Province and the Siziwangqi Potato Region of Inner Mongolia. The base fertilizer is made of 100 kg of three-element compound fertilizer per acre, Mengding's powerful bio-organic fertilizer is 60 kg per mu, and Mengding's microbial compound fertilizer is 2.4 kg. After mixing, it is spread on the surface and turned to the ground.
Fourth, sowing according to the temperature sowing around the time, when the 10cm depth of the ground temperature stabilized at 6-8 degrees Celsius can be sown, the sowing depth of 10cm, covering the soil thickness 15cm, row spacing 80cm, spacing 22cm. Planting density is about 3700 per mu.
V. Field Management
1. Cultivated soil: The first time the soil is cultivated when the white bud grows to 10cm in length, all the seedlings are buried at this time, the thickness of the cover soil is 6-8cm, and the second time the soil is applied when the seedling height is 15cm. For 5cm, it is best to bury the lower two leaves.
2, fertilize water: Fengmin Tonghe fertilizer (Fertilizer Fertilizer) to help you solve: the first time after the end of earth, 5-6 days after the seedlings all unearthed, according to soil moisture appropriate watering, potassium per acre Calcium-based kilograms 15-20 are applied with water. Large-scale sprinkler irrigation equipment uses pure Mongolian monobasic potassium dihydrogen phosphate for every 400 grams of water and 150 kg of foliar spray to increase chlorophyll content and increase photosynthesis. Spraying once every 10 days can significantly increase production. When the buds appear and grow parallel to the parietal lobe, this is the critical period for the nutrients required by the potato. Man irrigation equipment selection Jinfu Niuguo Li expansion 15 kg plus Jinfu cattle HA potassium 2 kg for 2 acres of land with water flushing facilities. Large-scale sprinkler irrigation equipment uses Mengli Shengfeng swelling fruit-specific 1500 kg foliar spraying per kg of water.
3, pest and disease control: plants grow to 20cm, with Mongolian tripod fight back each 15 kg of foliar spray, can effectively prevent potato early and late blight.
6. Timely harvest According to local climate conditions and market prices, the harvesting period can be appropriately adjusted. Potatoes in the western part of Inner Mongolia will be cut off 10 days before the potatoes are harvested, so that the potato skins will be aged to avoid mechanical damage during harvesting.
