The latest notice of soybean fertilization

Edamame is soybeans, soybeans are scientific names, and edamame is commonly known. Edamame bean is a kind of crop that likes temperature and water, which is generally planted in the summer in the south. Edamame bean cultivation needs a lot of nutrients to achieve the effect of high yield and high yield. Therefore, in the daily management, we should pay attention to fertilizing frequently and adding nutrients, but also pay attention to some problems in the process of fertilization. Let's take a look at it.

1. Types of fertilizers

First of all, it is necessary to apply fertilizer according to the growth and trend of edamame beans, such as the most common foliar fertilizer. If the growth rate of edamame bean is slow, the plant is weak and the leaf color turns yellow, this is the manifestation of nitrogen deficiency of edamame bean, so nitrogen fertilizer should be used mainly when spraying foliar fertilizer. On the other hand, if the edamame bean grows normally, the plant is tall and large, and the leaves are green and fat, it means that the edamame bean is rich in nitrogen. Therefore, at this time, foliar fertilizer should be applied more phosphorus and potassium fertilizer, depending on the situation.

2. Fertilizer concentration

Not only edamame beans, different plants, in different growth stages, different places also have different requirements for fertilizer concentration. If the concentration of fertilizer is too high, not only will not increase the growth rate of edamame, but also burn out the roots and leaves of edamame. When the temperature is high, if you want to spray foliar fertilizer, the concentration should not be too high, it should be about 60%. The concentration should be controlled within the suitable range of edamame. When the edamame bean seedlings are first unearthed, the concentration should be controlled below 50%, because the leaves of the newly unearthed seedlings are very tender, and the leaves will be burned out if the concentration is too high.

3. Fertilizer spraying time

The best fertilizer spraying time of edamame bean is in the growth stage of green leaves and tall plants, and the effect of fertilizer spraying is the best at this stage. If the leaves of edamame bean are not fully mature, not only the effect is not obvious, but also the fertilizer sprayed will be wasted. And the time of fertilizer spraying should be chosen in dry and rainless weather to ensure that there is no water on the plants and leaves, because if there is water, it will reduce the concentration of fertilizer and fail to achieve the desired effect. Spraying fertilizer in hot weather will cause the fertilizer to evaporate soon after it is sprayed.

4. Times of spraying

Many friends spray fertilizer completely depends on their own mood and time, spray when there is time, spray if you want. And many people think that the more fertilizer is sprayed, the better. In fact, this is not the case. For example, foliar fertilizer, foliar fertilizer is generally sprayed once a week or so, lasting for a month, because the content of foliar fertilizer is mostly some trace elements, too many trace elements can lead to edamame bean trace element poisoning.

These are some precautions about spraying edamame beans. In fact, these precautions are not only for edamame beans, but also for most vegetables. Even some crops that need a lot of nutrients to grow normally will have a degree, excessive not only can not promote growth, but also affect the development of crops.
