Teach you to grow potatoes well (part 1)

I. seed potato selection

The high yield of potatoes mainly depends on the seeds, and the quality of seed potatoes affects the yield and income of growers. Therefore, it is a major problem to identify the quality of seed potatoes. 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 block is soft in the hand, and it feels crisp and soft 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 potato species. Good potato species, strong disease resistance, good quality, high yield, generally up to 3500-4000 kg per mu.

II. Storage of potato species

It should be kept in a cool and ventilated place. To minus 3-4 ℃, potatoes should be covered with things, such as sacks, old clothes and so on. To minus 6-7 ℃ should be put in a closed house, in case of strong cold air should also be covered with a little more cloth, film, when the weather slows down, 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. Potatoes are afraid of heat, and the warmest place can not exceed 7 degrees Celsius. If the temperature is too high, a lot of buds will grow and the nutrients of seed potatoes will be consumed. Later, planting in the field will easily lead to a reduction in production. In short, potatoes are stored in winter, and the temperature in the house is not lower than zero without anything covered.

Third, the planting method of potatoes

1. Land management before planting:

Dutch potato is a highly adaptable crop, which can be used anywhere except saline-alkali soil, but it must be watered. The land where potatoes are to be planted next spring had better be ploughed in the first year, not only for ploughing, but also for deep ploughing. Potatoes like the soft soil most, and they are also the plants that can loosen the soil the most. If you plant potatoes for a few years, they will become soft and loose.

After deep ploughing or winter ploughing, after a winter, the frozen layer can reach 15 centimeters, this winter's cold and sunlight will have a good germicidal effect. This 15cm ripening layer is very beneficial to the growth of potatoes in the coming year.

Not only the first year of ploughing, but also deep ploughing, potatoes have several layers of creeping roots, so a deep soft soil layer is needed. In recent years, the depth of mechanical rotary tillage in the field can not meet the requirements, which affects the potato yield. therefore, in order to create high yield, the depth must be less than 20 cm. If it can reach 30 cm under the same planting conditions, the yield will be increased.

2. Budding:

Although potatoes are cool crops, they are not planted too early. in recent years, some farmers have begun to plant them before they are stung. The time is too early, the seed potatoes that have sprouted are unearthed quickly, and they are easy to suffer from the late spring cold in early spring. Potatoes that have been frozen are like people suffering from a serious illness, and it takes a certain amount of time to recover after the illness is cured. Therefore, once the potato is frozen at the seedling stage, it will affect the yield of the whole season. Therefore, the planting time should not be too early. The planting time of spring potatoes in the field had better be after the sting and before the Spring Equinox, and the specific time can be around the 16th or 17th of the lunar calendar.

Budding should be carried out before planting, the budding can be unearthed ahead of time, and the whole seedling is prosperous. If the potato is unearthed in advance, it will produce potatoes in advance, which will increase the yield and achieve the goal of increasing production and income during the whole potato growth period. The method and time of sprouting is 20 days before the sting, the potatoes are planted on the fire Kang, about 30-40 cm thick, the bottom of the Kang should be covered with grass, and the potatoes are covered with something. Burn a fire every day should not be too much, when the bud grows to about 1 cm, it is necessary to remove the cover, and to stop the fire, cool sprouts, a few days later the buds will become black and stout, manual buds are not easy to fall off. The second way to sprout is to plant potatoes in bamboo baskets, circle the baskets and light a stove in the middle.
