摘要
油菜在我县种植面积达3.2×104hm2,是我县第一大支柱产业,也是农民经济收入的最主要来源之一。为了建立互助县油菜测土配方施肥指标体系,为农民合理施肥提供依据,2007—2015年,在大量的"3414"田间肥效试验、校正试验、氮磷钾不同用量试验和基追肥不同比例试验基础上,探索出互助县油菜土壤养分丰缺指标与施肥指标体系,并通过实践运用,取得了良好的经济效益、社会效益和生态效益。
Rapeseed in our county planting area of 3.2 × 10^4hm2, is the first pillar industries, is the main source of economic income of farmers Huzhu County. In order to establish rapeseed soil testing and formula fertilization index system for farmers to provide basis for rational fertilization,2007 -2015, on a large number of＂ 3414＂ applied in the filed test, calibration test, different dosage test and base fertilizer NPK ratio test, based on the exploration of Huzhu County rape soil nutrient abundance index and index system of fertilizer application, and through the practice, has obtained the good economic benefit, social benefit and ecological benefit.
