Management points of Potato at Seedling stage

Potato is an important food crop in China, which has a wide planting area in our country. Potatoes will go through different growth stages during the whole growth period, among which the seedling stage is a very important period. And the management of the seedling stage also has a great impact on the growth of potatoes, so how should we manage them at the seedling stage? The following editor brings you the key points of potato seedling management, let's have a look!

1. Check and replenish seedlings

Potato seedlings in the successful emergence, we should pay attention to timely check the growth of potato seedlings, do a good job of inter-seedling work. Strong seedlings should be retained to provide enough space for them to grow. In addition, weak seedlings, pest seedlings and dead seedlings should be removed in time. If it is found that there is a lack of seedling hole, then it is necessary to make up for the same growth of healthy seedlings. If the lack of seedlings is more than 28%, you can properly replant some corn, green beans and so on. Improve the utilization rate of soil, avoid excessive loss, and improve the economic benefit of planting.

2. Ventilation and ventilation

Under normal circumstances, the potato seedling stage should be in early summer, when the temperature gradually rises. Therefore, potatoes grown in the greenhouse should pay attention to ventilation. When the temperature is above 16 degrees every morning, the vents should be opened in time for ventilation. Avoid the temperature in the greenhouse to exceed 25 degrees, too high temperature is very harmful to the growth of potato seedlings. If the ventilation is not done properly, the leaves of the seedlings may be burned. It should be checked every morning after emergence, and the potato seedlings should be roasted by breaking the membrane in time after breaking the soil.

3. Water and fertilizer management

The growth ability of potato in seedling stage is not strong, but the speed of leaf expansion is relatively fast, especially after entering the budding stage. The number of stems and leaves will increase sharply, and then the lateral branches will begin to grow. Therefore, in order to ensure the growth of seedlings in the rosette stage, a water and fertilizer work should be carried out at the rosette stage, and the fertilizer is mainly urea. The main growth site of seedlings is stems and leaves, which is also an important period of tuber formation in the later stage. At this time, there is a greater demand for nitrogen fertilizer, we should fertilize and water early to ensure adequate nutrients and water, and promote the growth of seedlings.

4. Ploughing and weeding

Ploughing and weeding is a management work that can not be ignored in every growth stage of potatoes. Mid-tillage can effectively improve soil permeability, improve the ability of soil to absorb fertilizer, and promote the nutrient absorption of seedlings. On the other hand, the weeding work can better concentrate the nutrition on the seedlings, prevent weeds from grabbing the growth and nutrition of the seedlings, hinder the growth of potato seedlings, reduce the yield and seriously affect the planting efficiency. Therefore, when planting, we must pay more attention to avoid some irreparable losses.

The above is a brief introduction of the main points of potato seedling management, we must pay attention to do a good job in these basic management work when planting potatoes, otherwise the impact is very great. This is the end of today's introduction, this article is for reference only, I hope it can be helpful to everyone!
