Black potato planting technology

Want to grow good black potatoes, it is best to choose a piece of land with a loose texture, good ventilation, and the soil fertility should be sufficient, so that the basis of high yield, and this piece of land is best not to have been planted in the previous sweet potatoes and peppers, etc., and it is best to be planted in the previous crop of wheat, maize, or cabbage, etc.. Before planting, the land should be plowed y once, at least 25-30 centimeters in depth, to ensure that all the soil is plowed very fine, without large pieces of soil, so that the ability to conserve moisture will also increase. When plowing the soil, you should spread enough sump on it, because black potatoes depend on a lot of fertilizer to produce high yields, so it is important to have enough fertilizer in place.

The organized land, the next thing to consider the sowing of seeds, before this must be a good choice of seeds, seeds must not have any wounds, so that the seeds have not been subjected to disease and damage, the surface looks smooth, and should be cut into cubes, all the seed pieces should be uniform, about 25 grams. In order to ensure that the seedlings can grow out earlier, to catalyze the teeth before sowing, germination should be about 20 degrees in the environment, and there should not be any sunlight.

Sowing to choose the most suitable time, black potatoes generally more than five degrees can grow, but the most suitable temperature is 18 degrees, so as long as the local temperature is more than five degrees can be sown, in the sowing to pay attention to the density of the seed, every 667 square meters of land can be planted out of roughly four thousand black potatoes. After planting, we should pay attention to good field management, in order to ensure that each stage of normal growth, fertilizer must keep up, in addition to timely watering, so that the soil is always moist.

While the general yield of black potatoes are very high, but also under the premise of normal planting, so these techniques must be clear, so as to ensure their own yield, in addition to preventing black potatoes from pests and diseases, once the disease appeared, all the hard work may be in vain.
