With the increase of farmers' understanding of biological bacterial fertilizer, the application of biological bacterial fertilizer in fruit and vegetable production is more and more extensive. In the process of agricultural production, by increasing the application of biological fertilizer, it can reduce the amount of chemical fertilizer, reduce production costs, improve soil structure, eliminate soil compaction, and improve the quality of vegetables. How does the crop properly apply biological fertilizer?
First, choose a product with reliable quality. The bacterial fertilizer must be kept in a low temperature, cool, ventilated, and protected from light to avoid failure. Some strains require a specific temperature range, so farmers should carefully select the fertilizer product. It is not advisable to choose an expired product at a cheap price. Generally, biological fertilizers for more than two years should be carefully selected. Units and individuals who do not have low-temperature storage conditions should use it shortly after purchasing biological fertilizer.
Second, the use of the method should be used as a base fertilizer, application, ditch or acupoint application; can also be used for topdressing, rooting, rushing, spraying and so on. The effect of biological bacterial fertilizer is better, especially when the accumulation of pathogenic bacteria in the soil is more. In addition, the use of biological bacterial fertilizer roots not only promotes the growth of vegetable roots, but also has a significant effect on inhibiting the occurrence of vegetable root diseases.
Third, to meet the requirements of biological bacteria fertilizer efficiency. Only after extensive breeding, the bacteria in the soil can form the scale of the soil to effectively reflect the function of the fertilizer. In order to allow the bacteria to breed as soon as possible, it is necessary to provide a suitable environment. condition. Regulate the ground temperature, soil moisture, maintain good soil aeration and suitable soil pH.
Fourth, try to reduce microbial deaths During the application process, avoid direct sunlight; add water when rooting. Biological bacterial fertilizer should not be combined with or mixed with insecticides, fungicides and coated seeds containing insecticides and fungicides. After using the bacterial fertilizer, do not use pesticides to irrigate the roots to avoid killing specific microorganisms in the bacterial fertilizer.
Fifth, pay attention to the application of organic fertilizer organic matter is the main energy source of microorganisms, organic matter decomposition can also supply microbial nutrients. If the application of organic fertilizer in the soil is insufficient, the biological bacteria will be ineffective due to lack of food. If the supply of organic matter in the soil is sufficient, the probiotics in the biological fertilizer will multiply in a large amount, thereby enhancing the inhibition of harmful bacteria. Therefore, we must pay attention to the application of organic fertilizer when applying biological fertilizer.
6. The application of microbial fertilizer with other fertilizers has low nutrient content and must be applied in combination with other fertilizers. In addition to being not suitable for mixing with chemical fertilizers such as ammonium bicarbonate, the bacterial fertilizer has many advantages in combination with other fertilizers. When a large amount of quantitative fertilizer is applied alone or the application of chemical fertilizer is uneven, it is easy to produce toxic side effects on the crop, and if it is mixed with the bacterial fertilizer, such problems do not occur.
7. Pay attention to the application of more bacterial fertilizer in the appropriate amount of soil. Although there is no burning phenomenon, the more it is not applied, the better. Blindly applying a large amount of biological bacterial fertilizer will increase the accumulation of salt in vegetable plants, harm the health of consumers and deteriorate the soil texture. Therefore, according to the needs of different crops and soil nutrient status, the amount of biological fertilizer applied should be scientifically determined. In order to achieve the purpose of increasing production and income.
Eight, it is not advisable to use a variety of biological fungi at the same time to use biological bacterial fertilizer to play a role, the need for beneficial microorganisms to multiply in order to play a role. There are three types of relationships between microorganisms and microorganisms: antagonism, parasitism, competition, and predation. It is necessary to pay attention to the continuous supplement of new bacterial fertilizers. For example, after using the base fertilizer, the same kind of biological bacterial fertilizer can be chased many times to enlarge the bacterial flora and improve the control effect.

Thermal insulation is the reduction of heat transfer (i.e., the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials.
Heat flow is an inevitable consequence of contact between objects of different temperature. Thermal insulation provides a region of insulation in which thermal conduction is reduced or thermal radiation is reflected rather than absorbed by the lower-temperature body.
The insulating capability of a material is measured as the inverse of thermal conductivity (k). Low thermal conductivity is equivalent to high insulating capability (Resistance value). In thermal engineering, other important properties of insulating materials are product density (Ï) and specific heat capacity (c).
