In terms of temperature, black beans like to grow in a warm environment with a temperature range. In the germination stage of black beans, the highest temperature should not exceed 25 degrees, and should be kept above 18 degrees to make black beans grow faster. Especially when black beans just emerge, the temperature requirement is relatively high, about 20~25 degrees, which is more conducive to its growth. After the later period, the temperature is kept at about 25 degrees, which is the favorite growth temperature of black beans.
Farmers can judge that if it is too cold, it is not suitable for growing black beans. Therefore, growers should think ahead and see if the local environment is suitable for this crop. If the temperature exceeds 35 degrees, black beans cannot grow. Therefore, growers should meet these conditions, and for better control, many people choose to plant in greenhouses, which have been in a relatively constant temperature environment, which is conducive to the growth of black beans.
Followed by water, black beans have a great demand for water. Especially in the early stage, black beans gradually become bigger and need water to support them, so growers should water them more and wait until they grow up slowly. In the middle and late stages of growth, the water demand will gradually decrease, so we just don't have to let it dry. Everyone should pay attention to control the degree.
Furthermore, in terms of light, don't let black beans receive strong light. If it lasts for a long time, it will delay flowering and mature later. Because they are sensitive to light, as long as they meet the needs. The temperature in some areas is too high, and it will be unbearable in summer. We need to consider covering black beans. As long as the leaves can carry out photosynthesis normally, the illumination time should not be too long.
Regarding the soil, black beans are not very demanding on it. It is necessary to check the soil in advance and measure its pH value first. Preferably a neutral environment. Too much acid and too much alkali are not conducive to the growth of black beans. Moreover, before planting, we should pay attention to turning the soil deeply to make it in a fertile soil environment, which will grow faster.
If the soil is too acidic, it will not be able to stabilize nitrogen, and its ability to absorb nutrients will be even worse, so naturally it will not grow too well. If the soil environment is alkaline, it is not suitable for planting black beans, because black beans belong to alkali-tolerant crops, so we'd better control the PH value of the soil between 6 and 7, and the difference is not too much.
Therefore, growers need to know clearly that the environment that black beans like is neutral soil and needs high temperature. At different stages, they should not be too cold or too hot, and the soil should be treated in advance. It doesn't like the light for too long, so these growers should grasp it clearly so as not to affect the growth of black beans in the later stage.
