In the prevention of vegetable dead trees, bacterial fertilizer plays a vital role. Therefore, more and more vegetable farmers recognize the importance of biological bacterial fertilizer in vegetable production. As a result, many vegetable farmers in production have shown excessive dependence on and use of bacterial fertilizer, and gradually entered the misunderstanding, which is mainly manifested in the following three aspects:
First, mixed with chemical fertilizers Some vegetable farmers believe that bacterial fertilizer can not be mixed with chemical fertilizers. After mixing, the high concentration of chemicals will kill the active bacteria in the sterilized fertilizer, thus causing the bacterial fertilizer to lose its effect. It is not known that the nutrient content of the bacterial fertilizer is very small, and it is difficult to meet the crop growth demand by using it alone.
The fertilizer can be mixed with the fertilizer. If calcium perphosphate or the like is applied to the soil, it is easily fixed, and mixed with bio-organic fertilizer can reduce the fixation and loss of nutrients. Moreover, when a large amount of chemical fertilizer is applied alone or the application of the chemical fertilizer is uneven, it is easy to produce toxic side effects on the crop, and if it is mixed with the bacterial fertilizer, the occurrence of such problems is reduced.
Second, the application of more bacteria fertilizer in the appropriate amount of soil, although there will be no burning roots, but the more it is applied, the better. Blindly applying a large amount of biological bacterial fertilizer, although it does not cause vegetable roots and dead seedlings like chemical fertilizers, but the accumulation of salt in vegetable plants increases, which is harmful to the health of the sanator and worsens the soil texture, but at the very least increases the cost of fertilizer input. (Because the price of biological bacterial fertilizer is higher), the cultivation efficiency of vegetables is reduced. Therefore, according to the needs of different crops and soil nutrient status, scientifically determine the amount of fertilizer applied to the biological fertilizer, in order to achieve the purpose of increasing production and income.
In the case of relatively normal soil conditions, it is generally appropriate to apply about 80 kg of biological bacterial fertilizer in acres (667 square meters). If the degree of soil salinization is high, the application amount of the biological fertilizer can be appropriately increased. Generally, according to the degree of salinization of the soil, it is appropriate to increase the application of 10-20 kg per mu (667 square meters).
Third, to meet the requirements of biological bacteria fertilizer efficiency Organic biological fertilizer contains a large number of soil microbial agents, these microorganisms can release soil insoluble phosphorus and potassium fertilizers, fertilizers, significant synergy after application. However, most of these microorganisms are aerobic fungi, and all their life activities require appropriate temperature, moisture and proper amount of oxygen. Therefore, it must be applied after the high temperature chamber, so as to avoid the high temperature of the chamber, so that it loses vitality, and it should be applied shallowly. The depth of the soil is 5-8 cm. It should not be deeper than 10 cm to prevent the lack of oxygen in the deep soil. It affects the activity of microorganisms and reduces the effect of use.
