The latest precautions for green bean cultivation

Kidney beans, also known as kidney beans, must be no stranger to them. String beans are the main vegetables in our lives, and their nutritional value must be not low. It calms the mind, prevents heatstroke, stabilizes the body's blood pressure and is rich in iron. It is the best food for people with iron deficiency and has a wide range of planting areas in our country. So what should we pay attention to in the planting process? Next, let's take a look at the notes for growing green beans with the editor.

1. Lighting

Kidney beans do not have a great demand for light, but they still need a certain amount of light time in the growth process, but the light time varies according to different varieties. The suitable light time can promote the photosynthesis of kidney bean and increase the nutrient accumulation of the plant. Usually the appropriate light length of kidney beans is about 4-6 hours, but it still depends on the variety. If the light time exceeds, it should be shaded properly to prevent the normal growth of kidney beans from being affected. Mainly according to the actual situation, appropriate lighting and shading.

2. Temperature

Although it is called string beans, it is not suitable for planting in all seasons, because string beans are suitable for growing in a warm environment and are very weak in resistance to cold and cold weather. The most suitable temperature for seed germination is about 25 degrees, which cannot exceed the temperature range of 10-40 degrees. And the seedlings are very fragile, and a slight change in temperature will affect them in varying degrees. If the seedling is in a relatively low temperature after germination, the color of the seedling will gradually decrease, and it will be frozen after it is below zero, so that it can not continue to grow.

3. Soil

Kidney beans have relatively strict requirements on the soil, and the soil suitable for growing green beans must be rich, soft and deep sandy soil. However, it can also grow in general clayey soil, but avoid planting in topographic clay, as it will affect the respiration of the roots, hinder the absorption of nutrients and prevent them from transmitting enough nutrients. The PH value in the soil is moderate, excessive acid and alkali will cause certain harm to the plant. Soil is the basis of crop growth, if there is not a piece of soil suitable for planting, then later management will be more troublesome.

4. Moisture

The roots of kidney beans grow fast and have strong extensibility, but they are not resistant to waterlogging. But on the contrary, a large amount of water is still needed when the seeds germinate, but we should pay attention to the water content in the soil, which makes the roots lack oxygen and the seeds can not germinate or even rot. Therefore, it is necessary to maintain an appropriate amount of water, which can not only provide plant growth, but also ensure that stagnant water will not be too much. When kidney beans grow to the flowering stage, the water demand gradually becomes more and more, and there are certain requirements for the humidity content in the air, which should not be less than 65%.

The above are several aspects that need to be paid attention to when planting green beans, in fact, we should also find that it is the environment needed for the growth of green beans. These are the most important basic tasks of growing green beans, and if they are not done well, it will be very difficult to plant them successfully. Therefore, when planting, we must improve all the preparatory work in order to make the first step of this kind of planting.
