Requirements for environmental conditions of beans

Beans are also called cowpeas, a vegetable that we often eat in our daily life. The planting of beans also has a large area in our country, and the market of beans is getting bigger and bigger, but there will still be many people who fail to grow them. In fact, growing beans is not as easy as you think. Beans have certain requirements on the environment. The following editor has brought you the environmental conditions needed for beans, let's have a look!

1. Soil

The adaptability of beans is relatively strong, the requirements for soil fertility is not very great, but want to grow high-yield, high-quality beans. Then we should try our best to choose deep, soft and permeable sandy soil. The first two crops of soil should not be crops of the same family and genus, otherwise all kinds of diseases and insect pests are more likely to occur. In fact, the choice of artificial planting soil is more important for the growth of beans, although it can grow normally in all kinds of soil, but its yield and quality of beans will certainly be affected to a certain extent.

2. Temperature

Beans are relatively warm, the temperature should not be too high or too low, its heat resistance and cold resistance are relatively poor. After sowing, the temperature should be controlled at about 22 degrees to promote seed germination, beyond the range of 8-35 degrees, its germination speed is very slow, and even can not germinate. After the seedlings break the soil, the temperature should be adjusted to about 19 degrees, not less than 13 degrees. Then when it reaches the flowering and podding stage, the most suitable growth temperature is about 25 degrees. If the temperature is too high and too low, it is easy to cause beans to fall flowers and pods. And if the accumulated temperature is less than 700 degrees after sowing, it will not bear fruit even if it blossoms in the later stage, so we should pay attention to the sowing time in spring.

3. Lighting

The growth of beans does not have a great demand for light, and the light time will not have much effect on the growth of beans. However, it is mainly based on the growth stage of beans, beans in the flowering and podding period and other peak growth period, there is still a certain demand for light. If the light demand of beans is not met during the peak growth period, it will easily lead to various physiological problems such as vigorous growth, falling flowers and pods. It has a great impact on the growth of beans, so we must control the light when planting so as to create a good growth environment for beans.

4. Moisture

Beans like to grow in a moist environment, but they are not resistant to waterlogging, but their drought tolerance is not poor. Therefore, during the growth period of beans, it is necessary to keep the soil in a moist state, and the soil water content should not be too much or too little, which can be kept at about 65%. If there is too little water, the flowering and podding of beans will be affected, the flowering time will be delayed, and the pod quantity and quality will be reduced. And bean seed germination also needs a certain amount of water, but not excessive, excessive, it is easy to lead to rotten seeds, affecting planting efficiency.

Therefore, we must do a good job of watering when planting, not only to meet the water needed for the growth of beans, but also to prevent excessive water leading to retting root rot, causing diseases and insect pests and other problems, posing a threat to the growth of beans.
