【Abstract】 Yumitou 102, a new single cross maize variety developed by Guangxi Maize Research Institute in recent years, showed the advantage of high yielding, fine quality, resistance to disease and to lodging in regional trial, and then has been authorized by the Committee of Crop Variety Authority. Adapted techniques in planting density were 51,000~55,500 plants/hm2 for fields with mid and higher fertility, 45,000~49,500 plants/hm2 for fields with lower fertility. For high yielding, production amount of fertilizer application should be about nitrogen 187.5~225 kg, P 2O 5 75~112.5kg and K 2O 187.5~225 kg in 1 hm2 during the whole growth period.更多还原
