When cooking usually blackens the potatoes grown in overpopulated the soil and stored in case of insufficient ventilation. These two factors lead to the lack of oxygen, causing the potato "choking". To prevent this from happening, once a week, check the basement and inspect stored vegetables.
It is important to monitor the humidity and temperature in the room. It is impossible to prevent the emergence of sweat on the lids of boxes, boxes and covering fabric. Perspiration causes rapid mould growth, which absorbs oxygen. Wet roots must be thoroughly dried and moldy and poveglia immediately remove.
Another reason for darkening of potatoes is the lack of potassium in the soil. During its growth the potatoes are consume potassium two times more than other minerals. But in some soils may not always be necessary for plants the amount of potassium. To solve this problem by adding the ground of any potash fertilizers, do not contain chlorine. And to the tubers during cooking blackened, you need a pan, add three or four Laurel leaves.
In addition to the reasons for the darkening of potatoes may be incorrect compliance with storage temperature and damage during harvest or transport. At harvest no need to throw the potatoes, allowing her to constantly hit her. Avoid extreme temperatures when storing. Before placing the potatoes in the basement, give him a little soak in a dry and cool place – this will allow the tubers to dry and gradually cooling off.
Peeled raw potatoes and after a while begins to darken because it contains compounds that interact with the air they begin to oxidize quickly. To avoid this the peeled roots must be filled with water.
Advice 2: How to plant potatoes
Potato - the second bread. In Russia it is on every plot. But how to plant potatoesto get a good harvest? Here there are subtleties.
In mid-April start to sprout potatoes. To better tubers sprouted, they should be folded in plastic bags at 50-80 pieces and put in enough warm, lit room. Soon the potatoes will begin to sprout and even adventitious roots. To plant potatoes usually start when flowering birch. This means that the earth will get warm enough.
When the time comes for planting potatoes, dig the field, so that the earth became loose. Shape on the field furrows with a size of 10-12 cm Distance between them should be approximately 70-80 cm Furrow can be done berestovica, any improvised tools, even feet.
Put in furrow seed tubers with the shoots facing up. Distance between tubers should be 30-35 cm and Then grown bushes will develop freely and will give a good harvest. After all the potatoes laid in furrows, it is necessary to cover it with dust. Better to do it than a shovel, and a rake. Should be a level field, without ridges - they appear when hilling. Potatoes will be in the ground at a depth of 6-10 cm, this will allow her to warm up.
On top of the potatoes put the fertilizer - compost, rotted manure, peat, ash, mineral fertilizers. When it rains, they fall into the ground and will nourish the tubers. The fact that the shoots of potatoes that spring up, and the roots appear just above the tuber. Therefore, they will get a sufficient amount of nutrients.
Advice 3: How to pick the early varieties of potatoes
Early varieties of potato and crops give before - after 50-60 days after planting. They are grown for summer consumption in Central Russia, where a short growing season, and also in the South before the heat. If you have a small house, put them on it early potatoes. It arrives to your table in the middle of summer. To get a good harvest you must skillfully choose the variety most appropriate for the area where there is your plot.
Be sure to choose planting material subject to zoning. For the North-Western, Western and Central regions of the European part of the country you want to buy only rakoustoychivyh varieties, such as "Vyatka", "Arina", "Warbah", "Bellarosa", "Rosalind", "Impala" etc. In the South, in the Volga region, where light soil with lack of moisture, it is better to grow varietiesresistant to drought and various viral diseases. Among them: "Spring", "Vineta", "Nevskiy", "good Luck."
Choose seed that is not grown South of Central Russia. Best in the Northern areas, for example, in the Arkhangelsk oblast or Komi Republic. Good seed potatoes are grown in the Leningrad and Murmansk regions. There, in the coastal Baltic sea site, summer is the cool weather. In the South due to high temperatures and numerous pests of potatoes is easily spread disease. Therefore, there is even the most elite varieties can degenerate in just one season. However, this factor is a big limiter of vectors — aphids, cicadas and the Colorado potato beetle.
Do not forget that palatability of potatoes is directly dependent on the starch content. The more starch, the better the vegetable. Increased compared with the other starch content of the early and mid-season have varieties of "Snow white", "Adretta", "nymph", "Svitanok Kiev".
When purchasing seed be sure to ask for a quality certificate. This will protect you from the fact that under the guise of "elite" you sell an ordinary potato. Should not be planted very small seeds — a good harvest will not work. In an extreme case, put in the hole 2-3 small potatoes.
Early and medium early varieties of potatoes to plant in late April – early may when the soil warms up to 6-8 degrees.
