In the production of non-polluting broccoli, the fertilizers allowed for broccoli are basically divided into four categories: organic fertilizers including human and animal waste, urine, compost, manure, biogas fertilizer, green manure, crop straw, mud fertilizer, cake fertilizer, grass ash, and slag. Except for grass ash and slag, the rest should be thoroughly cooked before application. After high temperature drunk, organic manure can be used to kill E. coli and other pathogenic microorganisms, which can reduce the volume and weight by 1/2 to 1/3, which is convenient for field transportation. In addition, unfermented organic fertilizers are fermented after being applied to the field, which can easily burn the roots.
Biological bacterial fertilizers include humic acid fertilizers, rhizobia fertilizers, phosphorus bacteria fertilizers, compound microbial fertilizers, and the like. Inorganic fertilizers such as sulfuric acid, urea, calcium superphosphate, and potassium sulfate are nitrogen-free potash fertilizers that contain neither atmospheric nor nitrate nitrogen, and broccoli-specific fertilizers are produced locally. The emblem element fertilizer is a fertilizer formulated mainly of copper, iron, osmium, zinc, elements of the same emblem, and beneficial elements.
The soil analyzer analyzes the nutrients that are needed for broccoli to grow nutrients. This will not only harmonize the nutrients of the soil and crops, but also reduce the waste caused by blind nitrogen fertilizers. The excessive consumption of potassium and potassium helps to maintain the nutrient balance in the soil slope, thereby increasing the soil fertility and providing a basis for the sustainable development of broccoli production.
