Synergistic agents: The main agents for enhancing fertilizer efficiency include new high fat film and photosynthetic nutrient film fertilizer. The new high fat film can automatically form an invisible polymer protective film, optimizing the water absorption, breathability, and light transmission quality of plants. Block the feeding signals of pests and diseases, weaken the transmission medium, and resist and defend against natural environmental disasters. Reduce pesticide toxins and improve the effectiveness of pesticide or fertilizer applications. Photosynthetic nutrient film fertilizer (photo fertilizer): It is a composite drug film that enhances the photosynthetic capacity of nutrients and chlorophyll, enhances the fertility, yield, color, leaves are thick, and stems are strong for advanced environmentally friendly plants. It can assist plants in absorbing a large amount of light fertilizer, light energy, light, compatible with conventional fertilizers, and provide nutrients for plant growth and development to the limit. One application benefits the whole year.Summary of fertilization scientific experiments: The entire process of fertilization for scallions is divided into two parts: base fertilizer and topdressing. 1. At present, it is important to pay attention to the areas where green onions are planted. The base fertilizer is mainly decomposed and high-quality organic fertilizer, which is sprayed during land preparation and plowed into the soil; Fertilizer base fertilizer should be applied with all phosphorus fertilizer, 40% nitrogen fertilizer, and 60% potassium sulfate fertilizer, and the variety can be compound fertilizer or elemental fertilizer. When selecting composite fertilizers, sulfur based universal or specialized fertilizers can be selected, and high nitrogen type composite fertilizers are not suitable. After the application of base fertilizer, a new high fat film can be sprayed 600 times overnight, automatically forming a layer of invisible polymer protective film, optimizing water absorption, breathability, and light transmission quality. Block the feeding signals of pests and diseases, weaken the transmission medium, and resist and defend against natural environmental disasters. Reduce pesticide toxins and improve the effectiveness of pesticide or fertilizer applications. 2. The top dressing of scallions can be carried out in 2-3 times, with the remaining 60% nitrogen fertilizer and 40% potassium fertilizer applied as top dressing during the full leaf stage and the early and middle stages of scallion white formation, respectively. Top dressing must be used in conjunction with photosynthetic nutrient film fertilizer, which can assist plants in absorbing a large amount of light fertilizer, light energy, light, compatibility with conventional fertilizers, and nutrient supply for plant growth and development to the limit. One application can benefit plants throughout the year.
