Growing environment of black bean

Black beans are actually black soybeans, but they contain more vitamins, yolk, especially melanin than ordinary soybeans, which are good nutrients for the human body. Regular consumption of black beans can delay the aging of body function and lower blood sugar. According to the medicine book, black beans can tonify the kidney and benefit the eyes. So what is the environment under which black beans grow and what are the requirements for the growth environment? Let's learn about it now. If you want to grow it, you must know it.

1. Moisture

It needs more water, the least in the growth period, the most in the flowering and podding stage, and between them in the pod expansion period. Seedling stage in order to take root more and quickly, generally less watering, to promote the root system, growth, which is beneficial to the growth of seedlings. Irrigation is only possible when there is a drought, so that the seedlings will not suffer from drought, root damage, inadequate absorption, and poor growth.

2. Temperature

Temperature is very important, black beans prefer temperature, germination to more than 18 degrees, but not more than 25 degrees, seedlings to 20 greenhouse between 24 degrees to grow fast. After the seedling stage, the most suitable temperature is between 24 and 26 degrees, mainly suitable for plant-by-plant growth, flowering can not exceed 30 degrees, more than flowers can not open, preferably between 25 degrees. More than 35 degrees affect growth. Afraid of the cold, cold areas, seasons can not be planted.

3. Lighting

Mainly short-day plants, long-day notes delay flowering and grow longer, but some varieties may be less sensitive to light and can grow, blossom and bear pods in longer light. The main reason is that you can choose to adapt to the local light varieties, or plant sparse in the field, which can increase the photosynthetic efficiency of leaves. Enhance the light.

4. Soil nutrition

The requirements of the soil are not strict, but it is better to be between 6 and 7.5 acidity, which is not easy for soybean rhizobium to grow and can not fix nitrogen, so the nutritional conditions are not so good. Excessive alkali of some trace elements, such as iron, affects the synthesis of chlorophyll. There is very little organic matter in jujube production. And black beans are not tolerant to salt and alkali, so it is best to plant in deep loose and fertile soil, so it is easier to grow and manage.

The main reason for the growth of Heidu is to have a warm environment and moderately acidic and alkaline soil, and it is best to need fertile and loose sandy loam. More water is needed for growth, especially in the flowering and podding period, which should be paid special attention to. Black bean is a short-day crop, long-day light affects flowering, so we should pay attention to the selection of varieties.
