Onions are a good vegetable, nutritious and market demand. And the onion crop is very adaptable, and it is actually very easy to grow. As long as you pay attention to scientific management, you can raise it very well. The following is a small series of Huinong. I will talk about the technical points of scientific planting management of onions. 1. Land preparation The adaptability of this kind of onion is very good, and the requirements for the land are not very high. Generally speaking, it is ok to choose sandy soil. After choosing the soil, remember to turn it over. It prefers loose soil, and then pay attention to the base fertilizer. The roots of onions are not very strong, and the effect of absorbing fertility is not very high, so it must be rich in fertilizer. It is recommended to use organic fertilizer, so that the nutrient elements are more abundant, including some trace elements, such as copper, boron, although the demand for these elements is not much, but the effect is very large. Make sure that the fertilizer and soil are fully dressed, so that the soil can contain nutrients at all levels. Second, colonization The adaptability of onions to temperature is still relatively strong, but the temperature should not be too high, otherwise the growth will start to slow down, the most suitable temperature is 21 ° to 27 °. When planting, be careful not to be too dense. Otherwise, it will affect the illumination. The distance between each line is about 20cm. And be sure to pay attention to separate management, such as the seedlings and seedlings do not plant in the same area. Third, management When planting onions, the temperature is generally low. At this time, the demand for water is not very large, and there is no need to pour a lot of water. Especially in the seedling stage, if the watering is too much, the temperature will decrease, and the seedling will grow slower. Of course, it does not mean that there is no need to water, and the growth of plants cannot be separated from water, so it is important to control the amount. After the leaves of the seedlings become thicker, the watering will be slightly more, and the water should be poured about ten days. However, do not water the water one week before the harvest, or it will affect the quality. Then, in the aspect of fertilizer, we must pay attention to the fact that the nitrogen fertilizer should not be used too much, otherwise it is easy to have a prosperous situation, which is also a problem that many novice growers often make. The above is the key points of the high-yield scientific planting management technology of Onion, which is compiled by Huinong. I hope that it will help everyone in the process of planting onions.
