一、精选地块花生每667平方米(1亩)产量650千克高产田应选择土层深厚(1米以上),耕作层肥沃,多年没种过花生的沙壤土。0～30厘米耕作层内有机质含量1.1%以上、全氮0.08%以上、全磷0.1%以上、碱解氮100毫克/千克以上、速效钾150毫克/千克以上。地势平坦,排灌方便。二、选用高质量增产潜力大的优良品种 First, the selection of land Peanut per 667 square meters (1 acre) yield 650 kilograms High yield field should choose a deep soil (1 m), fertile farming layer, perennials not planted sandy loam. The content of organic matter in 0-30 cm tillage layer is more than 1.1%, the total nitrogen is more than 0.08%, the total phosphorus is more than 0.1%, the alkaline hydrolysis nitrogen is more than 100 mg / kg and the quick-acting potassium is more than 150 mg / kg. Flat terrain, irrigation and drainage convenience. Second, the selection of high quality yield potential of the fine varieties
