Potatoes are potatoes. Almost every household grows. Potatoes grow mainly by potato stalks. How can they produce high yields? Some people say that they need to be good, but some people say that they don’t need it. Between the seedlings? Let's take a look at the next.

First, the situation of potato planting does not require seedlings

Generally, potatoes are planted with tubers. Before planting, the machine first ditches, then puts the potatoes into the ditch, and finally covers the soil with a machine, and finally covers the mulch. If you follow this method, then potatoes do not need seedlings, because the planting distance according to a certain plant spacing, the distance after emergence is also certain, so this situation does not require seedlings.

Second, potato planting should consider the problem of seedlings

Some growers in the north are suffering from freezing cold in the spring when they are planted, and their potato tubers do not ensure 100% emergence. Therefore, the amount of potato tubers used will increase when planting. In this case, the amount of seedlings will increase. The spacing is too small, and it is natural to carry out the seedlings later.

If it is not seedlings, it will cause the plant spacing to be too dense, which is not conducive to the subsequent ventilation and light transmission, affecting the expansion of potato tubers, resulting in small potatoes and low yield, which is not conducive to later sales.

If we planted potatoes at a certain interval, and there is no natural disaster, the emergence is also very good, and the latter can also be seedlings. The seedlings are mainly a measure taken when the potatoes are grown to about 10-15 cm. Planting potato tubers, people will pick good buds and then cut when cutting potatoes, but some potato tubers are not only one bud, some have two or even more.

If there is no seedling, there will be 2-4 plants per tuber growing, which is equivalent to competition. The amount of water and fertilizer is certain. After too many shunts, the result is only one. But the size is small, the quality is low, and it is naturally difficult to buy high prices.

Thinning practice:

When the seedlings are in use, it is recommended that each potato retains one of the best growing potatoes as the main seedlings, and the rest are eliminated to avoid competing with each other. Need to pay attention to the seedlings, try not to move the remaining new seedlings, you can use the hand to press the soil on both sides of the whole seedlings, and then remove the seedlings that need to be removed. If the number of seedlings is large, it is recommended to water the water after the end. Conducive to return to normal growth as soon as possible.

Third, the technical points of high yield of potato cultivation

1, variety. Nowadays, the potato species are basically from the potato breeding base, which are all virus-free seed potatoes, which are good in both yield and stress resistance.

2. Soil. Now planting is ridged and mulched planting, the soil is loose and fertile, and the drainage is convenient, which is very suitable for potato growth and late expansion.

3, fertilizer water. It is recommended that farmers' friends should apply a top dressing before the flowering of the potato when applying the base fertilizer. It is recommended that the three 15 compound fertilizers or the fertilization can be applied as soon as possible to promote the potato plants to cover the furrows and ridges, and enter the expansion period and the late growth stage. The leaf can be sprayed with 0.3% potassium dihydrogen phosphate, once every 7 days, 2-3 times, which can significantly increase the yield and quality of the potatoes.
