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. Thus, the production of many farmers exhibit excessive reliance on the use and situation of the fertilizer, and gradually into use errors, mainly in the following three aspects:
First, mixed with fertilizer
Some vegetable farmers believe that bacterial fertilizer cannot 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. And a large amount of fertilizer administered alone or more non-uniform application of chemical fertilizers, crop prone to side effects, if administered mixed with fertilizer, will reduce such problems.
Second, the right amount of application
More fertilizer is applied to the soil, although there is no burning phenomenon, but the more it is applied, the better. A large number of blind application of bio-fertilizer, although not cause root burn dead vegetable seedlings, vegetable plants just in vivo accumulation of salt increases, harmful consumer Eucharist health, deterioration of soil texture, but at least to increase fertilizer chemical fertilizers as input costs (Because the price of biological bacterial fertilizer is higher), the cultivation efficiency of vegetables is reduced. Therefore, it should be based on need and soil nutrient status of different crops, bio-fertilizer scientifically determine the amount of fertilizer, in order to achieve the purpose of increasing production.
In the case of relatively normal soil conditions, it is generally appropriate to apply about 80 kg of biological fertilizer in acre ( 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 to 20 kg per mu ( 667 square meters) .
Third, to meet the conditions of biological bacteria fertilizer efficiency
The organic biological fertilizer contains a large amount of soil microbial agents, which can release fertilizer elements such as insoluble phosphorus and potassium in the soil, and the effect is remarkable after application. However, these are mostly aerobic microorganisms like bacteria, they are all life activities, we need the right temperature, the right amount of moisture and oxygen. Therefore, it is necessary to be administered after a high temperature stew room, so as to avoid high soil temperature, making it lose its vitality stew room, but also light facilities, buried depth of 5 to 8 cm as well, can not be deeper than 10 cm, to prevent the lack of deep soil oxygen It affects the activity of microorganisms and reduces the effect of use.
