Selection and Storage of seed Potato

I. seed potato selection

The high yield of potato mainly depends on the seed. The quality of seed potato affects the yield and income of growers. Therefore, it is a major problem to identify the quality of seed potato.

Judging from the appearance of the seed potato, we should not only look at the size of the potato seed, but also look at the luster of the seed potato, which is good, fresh and without decay. The potato piece is soft in the hand, and it feels crisp and soft when cut with a knife. From the first half centimeter of the potato block, there is no ring rot (black circle). This can be said to be a better kind of potato.

Good seed potato, strong disease resistance, good quality, high yield, generally up to 3500Mu 4000 kg per mu.

II. Storage of seed potatoes

It should be kept in a cool and ventilated place. To minus 3 ℃ 4 min, seed potatoes should be covered with things, such as sacks, old clothes and so on. To minus 6 ℃ 7 should put it in a closed house, in case of strong cold air should also be covered with a little more cloth, film, when the weather turns warm, should remove the cloth or film.

The temperature in the house where potatoes are stored should not be too high and must not be placed by the fire. Potato seeds are afraid of heat and cannot exceed 7 ℃ in the warmest places (potatoes germinate when they are more than 7 ℃).

If the temperature is too high, it will grow a lot of buds and consume the nutrients of seed potatoes. Later, planting in the field will easily lead to a reduction in yield. In short, seed potatoes are stored in winter, and the temperature in the house is not lower than 0 ℃ without covering anything. Bao Jinshan
