A Detailed Guide to the Latest Key Points for Growing Green Beans
Green beans are also called kidney beans, and everyone is surely familiar with them. As one of the more common vegetables in our daily lives, green beans are certainly high in nutritional value. They have the effect of calming the mind and stabilizing the spirit, preventing heatstroke, and can also stabilize blood pressure. They are rich in iron. They are the best food for people who are deficient in iron, and they are widely grown in our country. So what should we pay attention to during the growing process? Let's take a look below with the editor at the key points for growing green beans!
1. Light
Green beans do not have a very large demand for light, but they still need a certain amount of light time during the growing process. However, depending on the variety, the required light time is also different. Suitable light time can promote photosynthesis in green beans and increase the nutrient accumulation of the plant. Usually, the suitable light duration for green beans is around 4-6 hours, but it still depends on the variety. If the light time is too long, appropriate shading should be provided to prevent it from affecting the normal growth of green beans. The main thing is still to adapt according to the actual situation, with appropriate supplementary light and shading.
2. Temperature
Although they are called four-season beans, they are not suitable for planting in all seasons, because green beans are suitable for growing in a warm environment and have very weak resistance to cold and low-temperature weather. The most suitable temperature for seed germination is around 25 degrees, and it cannot exceed the temperature range of 10-40 degrees. In addition, the seedlings are very fragile, and even a slight change in temperature will affect them to varying degrees. If after germination they are in a relatively low-temperature environment, the color of the seedlings will gradually fade, and after dropping below zero degrees they will suffer cold damage, making it impossible for them to continue growing.
3. Soil
Green beans have relatively strict soil requirements. The soil suitable for growing green beans must be fertile, loose and relatively deep sandy soil. However, they can also grow in general clay soil, but avoid planting in clay at low-lying terrain, because it will affect root respiration, hinder the roots from absorbing nutrients, and prevent them from transporting enough nutrients. The pH value in the soil should be moderate; too acidic or too alkaline will cause certain harm to the plant. Soil is the foundation of crop growth. If there is no suitable soil for planting, then later management will also be more troublesome.
4. Water
The roots of green beans grow quickly and have strong extensibility, but they are not tolerant of waterlogging. On the contrary, however, a large amount of water is still needed when the seeds germinate, but attention should also be paid to the moisture content in the soil. Too much will cause root hypoxia, and the seeds will be unable to germinate or even rot. Therefore, an appropriate amount of water should be maintained, which can both supply plant growth and ensure that there is not too much accumulated water. When green beans grow to the flowering stage, the water demand gradually increases, and there are also certain requirements for the humidity content in the air, which must not be lower than 65%.
The above are several aspects that need attention when growing green beans. In fact, everyone should have noticed that it is the environment required for green beans to grow. These are exactly the most important basic tasks for growing green beans. If these basic tasks are not done well, then it will be very difficult to succeed in growing them. Therefore, when planting, everyone must complete all the preparatory work well in order to do the first step of planting well.
