摘　　要：为提高配方肥在云南植胶区的覆盖率和到位率,打破技术推广"最后一公里"的"坚冰",在云垦江城橡胶公司建立橡胶树配方施肥示范区7 220 hm2,通过3年的示范,干胶净增产率达22.5%,单位面积净增产干胶326.6 kg/hm^2,示范区增产干胶2 133.8 t,产生经济效益2 546.0万元。在云南主要植胶区的11个橡胶农场推广施用橡胶树配方肥8.61万hm^2,橡胶干胶产量平均提高9.74%,增产干胶9 756.07 t,共新增产值1.46亿元,提高了橡胶树对症施肥的效果。A field experiment was conducted to improve the rate of formula fertilizer and break the ice of technical promotion. Rubber fertilizer demonstration area of 7 220 hm2 was established in Jiangcheng rubber company. Through three years of demonstration, the dry rubber as net production rate was 22.5%,and the net production of dry rubber was 326.6 kg/hm2. Dry rubber yield was 2133.8 tons, and the economic benefit was 25.46 million Yuan in Demonstration area. Rubber formula fertilizer was promoted the application of 1.291 3 million mu in 11 farms of Yunnan rubber plantation. The results also indicated that the production rate of dry rubber yield was increased averagely 9.74%, dry rubber yield was 9 756.07 tons, and the economic benefit was 146 million Yuan in Demonstration area. Rubber formula fertilizer improved fertilization effect, provided the technical support to achieve the efficient use of the rubber plantation nutrient. We will not only research new efficient environmental protection fertilizer through the combination of formula fertilizer and controlled release technology in future, but also innovate its promotion mode in order to realize rapid spread and promotion of new fertilization technology.
