How to grow potatoes

Potato is a very common ingredient in life, it is very popular with consumers. Potatoes are rich in starch, which makes people feel full, even in some places, potatoes are used as staple food. It is cultivated in many areas of our country.

How to grow potatoes

1. Pick potatoes first as seeds. If you bought it directly from the seed company, I won't say much. Then cut the potatoes in two or four quarters with a knife. To cut them in half, the knife should not carry oil. If there is residual oil, please wash and dry it. I won't say more about the reason. Sprinkling the cut potatoes with some carbon dust or dry soil is mainly to protect the cut wounds from the wind and inflammation, and then put the dusted potatoes in a dry place in the house, not in the place where they are facing. Where the wind blows. After the yards are finished, sprinkle more ash cover on the surface. It is better to use potatoes if there is no ash. Cover it like this for five or six days.

2. Prepare base fertilizer. There are many kinds of base fertilizers, and the usage and dosage of each one are different from the test. If they are not used properly, the potatoes will be burned to death. Otherwise, the potatoes will be too vigorous and produce very little. Let me say a few points below: If you are in a rural area, you will definitely shut down the livestock. Make the livestock excrement into a pile and growl outside for a few days to dig up to see if there is heat. It can be used. Cover the potatoes with small and large soil. If you do n’t have a domestic animal, you can groan with vegetables or weeds that you do n’t want. If you do n’t have these base fertilizers in cities, you can go to the market and buy processed base fertilizers. Not so troublesome.

3. After a few days have passed, dig the ground out of the ditch, about one foot deep, and the width is almost straight. This will be easy to take care of in the future. Pick up the covered potatoes and shake them. Don't shake them too clean. There should be sprouts of potatoes here. Don't break the sprouts. The best way is to sprout the buds. Put the potatoes into a straight line about six inches in a straight line for future care. Then put the bottom fertilizer, and finally cover the soil to cover the depth to a uniform thickness, as large as five or six inches thick soil, the loose cover can not be compacted.

Potato growth habits

1. Potatoes like cold and cold, and they like low-temperature crops. The formation and growth of underground potato chips requires a loose, breathable, cool and humid soil environment.

2. The temperature requirements of potatoes: the suitable temperature for tuber growth is 16 ℃ ～ 18 ℃, when the local temperature is higher than 25 ℃, the tuber growth will stop; the suitable temperature for stem and leaf growth is 15 ℃ ～ 25 ℃, and the growth will stop when it exceeds 39 ℃ .

3. Potatoes have only been introduced to China for more than three hundred years. It is said that it was introduced by overseas Chinese from Southeast Asia. In the 21st century, China's potato planting area ranked second in the world. Potato production is high, nutritious, and adaptable to the environment. It is now spread all over the world. It can also be cultivated and obtain higher yield in the cool season.

Potato Fertilization Technology

One is to use high-quality organic fertilizer as the main part of the fertilization; the second is to insist on the organic fertilizer and the three-element chemical fertilizer combined application, of which the three-element chemical fertilizer should be used as the base fertilizer 2/3 of the total growth period, leaving 1/3 for top dressing. The application rate of 1500-2000 kg of base fertilizer per 667 square meters of potatoes is: high-quality organic fertilizer 2000-3500 kg, urea 12 kg, superphosphate 20-30 kg, grass ash 150-200 kg or potassium chloride 10-15 kg. The above fertilizers and organic fertilizers are evenly mixed together and applied as a base fertilizer in the soil layer below 10 cm, so that the potato layer can be loosened, which is conducive to the absorption of potato roots.

Potato pest control

1. Aphids suck the plant juice, curl the leaves, consume a lot of nutrients, and destroy the photosynthesis of the leaves, and spread the virus, which has a particularly great impact on the production of potatoes. The potato grows in spring and the climate is dry, which is conducive to the occurrence of aphids. Control method: chemical control, use 2.5% bifenthrin emulsifiable concentrate or 10% chlorambucil wettable powder, such as spraying with 70% aphidone 1500 times solution, washing powder can be added to ablate the secretion of aphids Wax, the effect is better; during the flight period, yellow board can be coated with engine oil to lure.

2. The grubs can damage the roots of the potato during its entire growth period, and the adults can damage the aerial parts of the potato. Control method: chemical control, spray the soil surface with 1500 times solution of 50% phoxim emulsion before turning the ground; the organic base fertilizer should be applied only after it is thoroughly rotted; pay attention to the rotation; the grubs have serious plots, and continuous pouring can be used twice The water method is simple and effective.

When planting potatoes, the first step in grasping the potato's growth habits is to choose good varieties, and then to fertilize the land well, and then sow in time. In the later period, field management should be done well. Potatoes are also susceptible to pest infestation, and the work of pest control should be done well.
