Management measures of Potato before and after emergence

In the emergence stage of potato, it is the key period to ensure early emergence, whole seedling, promote strong seedling and lay the foundation of high yield, so the management of this period is very important. So how to manage potatoes before and after emergence? Let's take a look at the management measures before and after potato emergence with the editor.

1. The seedlings are fixed

After the potato seedlings are unearthed neatly, the seedlings, inter-seedlings and fixed seedlings should be checked in time, and those lacking seedlings should be replenished in time to ensure that they are comprehensive. After completing the seedlings, the seedlings should be fixed in time, and the seedlings should be weak and strong. 3-4 seedlings should be left in each hole in the first time, and 1-2 seedlings in each hole after the second time.

2. Cultivate the soil by ploughing.

Middle ploughing and loosening soil can make the potato layer soil loose and ventilated, which is beneficial to root growth, creeping elongation and tuber expansion. Before emergence, if the soil is hardened, the soil should be loosened immediately to facilitate seedling emergence. After finishing the seedlings, the first intertillage should be carried out at a depth of 8-10 cm, combined with weeding, and the second intertillage should be carried out 10-15 days after the first intertillage. In the potato bud, the third intertillage is carried out, and the second intertillage is shallow, and the soil needs to be cultivated at the same time, the thickness of the soil is not more than 10 cm, in order to thicken the potato layer, avoid the potato pieces exposed, and reduce the quality.

3. topdressing at the right time

Because potato takes a long time from sowing to emergence, it is necessary to apply bud fertilizer with clear dung water and a small amount of nitrogen fertilizer as early as possible to promote the rapid growth of seedlings. In the budding stage, combined with soil topdressing and one-time potato fertilizer, potassium fertilizer is the main fertilizer, combined with nitrogen fertilizer, and the amount of fertilizer should be determined according to the plant growth. After flowering, there is generally no need to fertilize the potato. If the potato shows the phenomenon of de-fertilization and premature senescence in the later stage, foliar fertilizer can be sprayed with phosphorus and potassium fertilizer or trace elements.

4. Chemical regulation

In the budding stage, spraying evenly with 35 grams of multi-effect frustration and 60 kilograms of water per mu, on the one hand, it can prevent potato plants from overgrowing, dwarfing plants, thickening leaves, thickening stems and deepening leaf color, and on the other hand, it can also promote the growth of underground parts. accelerate tuber expansion and increase yield. At the same time, it is also necessary to do a good job in epidemic prevention and underground pest control to ensure a high yield and harvest of potatoes.
