What is the method of growing potatoes? What do you breed with?

Potato is a food crop widely cultivated all over the world. Its tubers are rich in starch, protein, amino acids, vitamins and minerals, which can provide rich calories for human body. So, what is the potato growing method? Breeding with what?

What is the potato growing method?

1. Timely sowing

Potato planting time is generally around March of each year, need to wait for the planting of soil thaw, and when the temperature of 10cm soil layer stable through 10℃ for 3 consecutive days, you can sow. The specific sowing time should also be determined according to the geographical environment and climate type of each place.

2. Soil preparation and fertilization

Should choose fertile soil, deep soil layer, loose, good permeability of the plot. Before sowing, stubble cleaning and deep ploughing should be carried out 20 cm. Combined with ploughing mu, apply decomposed organic fertilizer 2000 kg/mu, and at the same time, according to soil moisture, add more than 20 kg compound fertilizer (nitrogen, phosphorus and potassium ratio is 1: 0.5: 2).

3. Seed potato treatment

Select suitable excellent varieties, and should be germinated treatment, can be spread under scattered light, maintain 15-20℃, directly promote short strong buds, sowing; before sowing, plant ash plus chlorothalonil plus new lipid film for seed dressing, promote the cut edge as soon as possible healing, reduce seed rot, increase potassium, disease prevention.

4. Reasonable close planting

Ridging on flat ground or ridging after breaking the original ridge, ridge spacing 80~90cm, single row cultivation, plant spacing 15~20cm, covering soil thickness 10~15cm. The number of seedlings per mu is 4000~5000. According to the variety and soil fertility, early-maturing varieties should be planted densely and late-maturing varieties should be planted sparsely.

5. Field management

It is necessary to loosen soil, cultivate soil and ridge in time, water in time, intertill and weed, apply fertilizer reasonably, and spray Diguozhuangdiling in time before flowering, tuber formation period and expansion period of potato, so as to effectively control the excessive growth of branches and leaves on the upper layer of the ground, accelerate the ultra-fast expansion of underground tubers, enhance the ability to resist pests, and ensure the high quality, high efficiency and bumper harvest of potato.

6. Prevention and control of pests and diseases

3-4 bottles of phoxim/mu are applied when sowing or before potato bearing to eliminate underground pests, and new lipid film is sprayed to improve the efficacy; meanwhile, for aphids, ladybugs, early blight, late blight and other pests, the targeted chemicals can be sprayed according to plant protection requirements to kill, and at the same time, 800 times solution of new lipid film is sprayed to consolidate the effect.

7. Timely harvest

Harvest when reaching physiological maturity, early maturing varieties in mid-late August, mid-late maturing varieties in mid-September harvest. About a week before harvest, potato fields are mechanically cut or chemically destroyed, and stems and leaves are cleared from plots. The digging depth should be reasonable when harvesting to prevent potato loss and skin damage. Handle with care during shipment, and prevent sun, rain and freezing damage during transportation and storage.

2. What do potatoes breed with?

It is propagated mainly by bud eyes on tubers. Plant reproduction mode is divided into sexual reproduction and asexual reproduction, through the sperm and egg cell combination of reproductive mode called sexual reproduction; do not need the combination of sexual reproductive cells, the mother directly produces new individuals, this reproductive mode called asexual reproduction; potato use bud reproduction on the tuber, not through the combination of sexual reproductive cells, but there are new individuals directly produced by the mother, belonging to asexual reproduction.

In addition, if you want to get high yield of potato, you should choose the right variety according to planting season, crop rotation and market demand. Seed potato should have good appearance, shallow bud eye and smooth skin.
