Potatoes, as a common vegetable on people's tables, are loved by people of all ages. At the same time, because potatoes are shelf-stable, they are planted in every household in the countryside. When it comes to potato planting, although it is relatively simple, it still requires a certain amount of technology to plant potatoes well and harvest more potatoes. Among them, some villagers have discovered such a problem: after their potatoes are planted, there are straight seedlings and no potatoes. This article will focus on this issue and talk to you about it.
First, the problem of potatoes growing seedlings
When encountering such a problem, the first thing we should think of is the problem of potato seedlings growing up. Here, it is necessary to talk about the growth stages of crops, which can generally be divided into vegetative growth and raw growth. When crops are growing vegetatively, the nutrients absorbed by the roots and the nutrients produced by the photosynthesis of the leaves will be preferentially supplied to the growth of the leaves and branches.
When the leaves and branches grow rapidly, the nutrient supply for the growth of crops is insufficient, and the potato seedlings will not bloom. Even after fruiting, the potatoes will be small due to insufficient nutrient supply. So, what are the influencing factors for the growth of potatoes?
Crops should grow, and there are several influencing factors:1. Over-application of nitrogen fertilizer. In the growth of crops, nitrogen is conducive to the growth of crops, and frequent application of nitrogen fertilizer will easily lead to crop growth. 2. The temperature is suitable. In the early stage of potato seedlings, crops are prone to vigorous growth at the right temperature. 3. Water frequently. This is mainly reflected in the early and middle growth of potato seedlings, because of frequent watering, so that the crop has suitable conditions, resulting in the growth of branches and leaves.
Second, the problem of potato breeding.
Under normal circumstances, potatoes grown in rural areas are used to breed potatoes that have not been eaten in the previous year as the next year. Because of the lack of understanding of breeding technology, many villagers will sow potato seeds due to pathogens and other reasons, resulting in less potatoes in the later stage.
3. How to improve the problem of potatoes growing straight and not bearing potatoes?
1. Improvement of potato crops: Through the above content, we can avoid the growth of potato crops through several aspects. On the one hand, when we plant potatoes, we use less single chemical fertilizer and mainly compound fertilizer. On the other hand, when the potato seedlings are growing, the application of potassium fertilizer is used to regulate the growth stage of the crop. If the potatoes have long growth, they can be controlled by spraying a growth control agent.
2. Improve potato breeding: When potato breeding, we should change the existing planting habits. According to the purpose of everyone's planting, it is still unrealistic to directly buy detoxified breeding potato seeds. However, at present, some villagers have found a better way to sterilize. Some villagers breed potatoes with some plant ash before sowing seeds. Grass ash plays a certain role in sterilization here.

Summary:
Because the yield of potato crops is relatively high, most of the villagers do not care about the yield of potatoes, so in the countryside, everyone grows potatoes more "Buddhist". However, if you want to have a high yield, you must pay attention to many aspects.
