Angola corn yield was at an average of 4000kg/km2 record at the highest level in 1973, and the yield at present is less than 600kg/hm2, there is a lot of space to increase production. In Angola, some private farmers are sowing hybrid corn seeds and fertilizer, new irrigation and water conservancy facilities are also being in constructed. With the promotion of hybrid seeds, the improvement of irrigation conditions and the increased amount of chemical fertilizer, corn yields will be greatly improved. Calculated as yield production increased 1 ton per hectare, total corn production will increase 1.122 million ton, the total production will be 164.8 ton.,then Angola will be self-sufficiency on maize.The main materials in this research screening in Camacupa province in Angola are new varieties breeding from China, This article mainly research from the screening of new varieties, the screening of fresh corn, the Core species density test,and the fertilizer experiment and sowing test, to select new varieties of maize that suitable for local cultivation in Camacupa province. The research results show that----------the varieties of Quan yu 1, Quan yu29 and Quan yu 39 are suitable for planting in Camacupa province.The Core species density tests showes that the best planting density of Quan yu 1 is 67500 plants/hm2, PAN53, PAN12 and Quan yu 39 are 60000 plants/hm2.The fresh corn test shows that the jade 103 in camacupa farm, when planting density is 52500 plants/hm2, the agronomic traits and the uniform of grain are better than other seven fresh corn combinations, suitable for cultivation in this region.The sowing test shows that light energy utilization rate of broadcasting corn is low, plant diseases and insect pests are heavier because of the poor Ventilation and translucent, and advantages of mechanized operations is not available, so the main way of sowing maize seed is mechanical sowing in the future.fertilizer test shows that nitrogen should be applied at about 450 kg/hm2 with the aiming yield at 7500kg/hm2,Varieties screening test shows that according to each factor, Quanyu29, Quanyu39 and Quanyul are the best varieties to plant in camacupa farm in the same ecoclimate fromOctober2013 to April 2014.
