向菲律宾推广中国高产木薯品种及栽培技术，在东达沃省进行了“良种＋良法”配套栽培技术的应用试验研究，引入6个中国高产木薯品种和当地主栽品种GY进行品种对比试验。结果分析表明，6个木薯新品种与GY品种之间产量差异性显著（Duncan=0．05），GR4、SC205、SC5、GR5、NZ199、SC8品种产量均优于GY，平均增产51．4％；5个新品种淀粉含量较对照提高1．2％～2．4％。同时，对所有参试品种就不同施肥水平效果进行试验，结果分析（Duncan=0．05）表明，品种问产量差异性不显著，而不同施肥水平间产量差异性显著；在相同的参试品种间，施肥水平2、3产量均优于水平1，建议生产中使用施肥水平2（N：P205：K20=2：1：3），施用氮肥、复合肥、钾肥各45．7kg／hm2、150kg／hm2、70kg／hm2。为加快木薯“良种＋良法”配套栽培技术集成研究和应用提供理论依据，为新品种和新技术在菲律宾的示范与推广打下前期基础。

6 Chinese high-yield cassava varieties and the corresponding cultivation technique were introduced to Davao Oriental, Philippines, and the comparative experiment was done with the local main cultivar GY. The experiment results （Duncan=0.05） showed that there were significant yield differences between the 6 Chinese cassava varieties and the local variety GY, all the yield of the 6 varieties were better than that orGY, and had an average increase of 51.4 %; The starch content of the 5 Chinese varieties increased by 1.2 % -2.4 % than that of the control. Meanwhile, the effects of the different fertilization levels on all tested varieties were tested, and the results （Duncan=0.05） indicated that the yield differences among the varieties were not obvious, but between the different fertilization levels were significant; in the same variety, fertilization levels of 2 and 3 were better than that of 1, and fertilization level 2 （ N：P205 ：K20=2：1：3 ） should be recommended for the production. The best fertilization level was Nitrogen fertilizer 45.7kg/hm2, Compound fertilizer150 kg/hm2 and Potash fertilizer 70 kg/hm2. The study results could provide a theoretical basis for accelerating the integration research and application of the corresponding cultivation techniques of ＂improved variety ＋ good method ＂ of cassava, and lay a foundation for demonstration and extension of new variety and technology in Philippines.
