文山州是云南省辣椒的主产地之一,辣椒已成为当地发展经济的重要支柱产业,常年种植面积139.95万亩。由于农民缺乏科学有效的施肥技术指导,辣椒生产上的施肥多凭经验盲目用肥,滥施、偏施或过量施用化肥等现象突出,造成耕地土壤氮、磷、钾养分比例失衡,肥料利用率低,土壤退化,严重影响了辣椒的产量和质量。2005年国家测土施肥项目实施以来,采用“3414”试验研究作物丰缺指标的方法得到广泛应用,但利用“3414”试验构建辣椒的
Wenshan Prefecture is one of the main producing areas of pepper in Yunnan Province. Pepper has become an important pillar industry for local economic development with annual planting area of 1,389,500 mu. Due to the lack of scientific and effective fertilization guidance, the fertilizers in pepper production blindly use the experience of fertilizer, excessive use, partial application of excessive fertilizer or other phenomena prominently, resulting in arable land soil nitrogen, phosphorus and potassium imbalance in the proportion of nutrients, fertilizer utilization Low, soil degradation, seriously affected the yield and quality of pepper. Since the implementation of the national soil testing and fertilization project in 2005, “3414” experiment has been widely used to study the index of crop abundance and deficiency, but the method of “3414”
