琼海市位于海南岛的东部,地处热带北缘,属于热带季风及海洋湿润气候区,长夏无冬,光温充足,雨量充沛,光合潜力大,是海南比较适宜反季节辣椒种植的主要市县之一。在反季节辣椒生产中,普遍存在施用氮、磷、钾肥不合理以及施肥时期、施肥方法不当等问题,导致种植成本偏高、土壤养分失衡、土壤酸化和沙化、生物多样化衰退等,严重制约了高产、优质、高效反季节辣椒生产及其产业的可持续发展。因此,根据当地土壤肥力
Qionghai City is located in the eastern part of Hainan Island, located in the northern margin of the tropical, belongs to the tropical monsoon and marine humid climate zone, no summer long, light and temperature sufficient, abundant rainfall, photosynthetic potential, Hainan is more suitable for off-season pepper cultivation One of the county. In the production of off-season peppers, problems such as unreasonable application of nitrogen, phosphorus and potassium fertilizers and improper fertilization methods have led to serious restrictions on high planting costs, soil nutrient imbalance, soil acidification and desertification, and the decline of biodiversity The production of high-yield, high quality, efficient off-season pepper production and sustainable development of its industry. So, according to the local soil fertility
