Skillful use of microbial agents to cut off soil-borne diseases of strawberries from the root
Strawberries are sour, sweet and delicious, suitable for all ages, with high nutritional value and considerable economic benefits. However, in the process of strawberry cultivation, chemical fertilizers and pesticides are used very frequently. in the long run, the soil structure is destroyed, the species and number of soil microorganisms are greatly reduced, resulting in the absorption and utilization of soil nutrients and the decline of plant resistance. harmful substances can not be decomposed in time, strawberry Verticillium wilt, Fusarium wilt, root rot and other soil-borne diseases become more and more serious, seriously affecting the economic benefits of strawberry planting!
To avoid the occurrence of strawberry soil-borne diseases, first of all, it is necessary to increase the content of organic matter in the soil, such as applying farm manure, returning crop straw to the field, planting green manure crops and so on. Secondly, it is necessary to increase the species and number of beneficial microorganisms in the soil, and the application of microbial agents can achieve significant results. In the process of strawberry cultivation, these two aspects must be combined and promoted each other in order to avoid the infection of soil-borne diseases.
Microbial agents contain a large number of highly active beneficial bacteria, which can fix nitrogen, dissolve phosphorus and potassium, and transform the organic matter in the soil into nutrients that can be absorbed by plants. In the process of reproduction, beneficial bacteria can also release bacteriostatic substances such as antimicrobial peptides and lactic acid, which can significantly control a variety of soil-borne diseases, improve plant disease resistance, and improve quality and yield. In addition, the application of microbial agents in strawberry cultivation can also degrade the residual pesticides and heavy metals in the soil, making the strawberries more safe and healthy.
