本文从土壤洪肥性和依存率分析了冀东潮褐土,以小麦、玉米为主栽作物,实现吨粮田的土壤条件.作物产最水平与依存率大小呈正相关,小麦亩产400kg,玉米亩产600kg,依存率分别为>65%和>55%.提出有机质制约值为1.2%,有机质培肥范围为1.2～1.5%,土壤C/N为8.7～9.9.吨粮田要求土壤供氮17.3～20.4kg/亩,其中麦季供氮7.8～9.6kg/亩,玉米季供氮9.5～10.8kg/亩.供磷6.1～7.7kg/亩,其中麦季3.3～4.1kg/亩,玉米季2.8～3.6kg/亩.供钾16.0～20.1kg/亩,其中麦季6.8～6.0kg/亩,玉米季9.2～11.1kg/亩.
In this paper, we analyzed the soil moisture and fertility and the interdependent rate of the Jidong Cinnamon soil, wheat, corn-based crops, soil conditions to achieve tons of grain.The crop production level and the size of the dependency was positively correlated wheat yield of 400kg, corn acres The yield of organic matter was 1.2%, the range of organic fertilizer cultivation was 1.2-1.5%, and the soil C / N was 8.7-9.9. ~ 20.4kg / mu, of which 7.8 ~ 9.6kg / mu for wheat and 9.5 ~ 10.8kg / mu for corn, and 6.1 ~ 7.7kg / mu for phosphorus, of which 3.3 ~ 4.1kg / 2.8 ~ 3.6kg / mu for potassium 16.0 ~ 20.1kg / mu, of which wheat season 6.8 ~ 6.0kg / mu, corn season 9.2 ~ 11.1kg / mu.
