Moreover, the soil components are complex, and the growth of various harmful components and the large-area generation of soil-borne diseases and pests are caused due to the growth of the planting years, and the soil-borne diseases and pests can also become the generation places of the pests and the weeds. In order to control all factors in the whole planting process, various water culture technologies based on inorganic chemical nutrient solution are developed, the technology does not need to repeatedly turn over soil, the planting efficiency is greatly improved, the planting environment is uniform, and the quality of planted products is relatively standardized.
But also brings new problems, such as high cost of the nutrient solution itself, and if the nutrient solution is recycled, the pH environment, EC environment, microbial environment and nutrient change of the absorbed nutrient solution bring unpredictable adverse effects to planting. If the waste water is not recycled, the waste water is directly discharged into an environmental water area, and pollution pressure is brought to the environment. And the hydroponic planting is characterized in that the inorganic nutrient solution does not contain buffer components, factors including pH and the like easily change greatly, so that the water body generates diseases, the whole disease is easily enlarged, and the planting risk is extremely high, so that the requirements on the environmental control and the technical level of planting facilities are extremely high, the cost and the operation cost of the stably-produced hydroponic system and facilities are usually high, and the large-area popularization is difficult.
