玉米一般用高氮中磷低钾氯基复合肥80-100斤做底肥，或者三个15的氯基复合肥做底肥的。玉米追肥的最佳时期在拔节至穗分化期，此时玉米已经 7-12 片叶，正是雌穗生长伸长至雌小花分化期，是决定玉米穗长穗粗的关键时，此时追肥能满足拔节孕穗对养分的需要，促进穗分化，使玉米穗大粒多。每亩追施尿素30-40斤。绛旓細3. 鎱庣敤姘７閽惧钩琛＄殑澶嶅悎鑲ユ枡銆傜敱浜庝换浣曚綔鐗╁姘佺７銆侀捑鐨勯渶姹傞噺閮戒笉鏄潎琛＄殑锛屼娇鐢ㄥ钩琛″瀷澶嶅悎鑲ュ彲鑳藉鑷存煇浜涘吇鍒嗚繃鍓╋紝閫犳垚娴垂锛屽苟鍙兘鎶戝埗浣滅墿瀵瑰叾浠栧吇鍒嗙殑鍚告敹锛屽奖鍝嶆柦鑲ユ晥鏋溿4. 閬垮厤鍗曠嫭浣跨敤纾烽吀浜岄摰浣滀负搴曡偉銆鐜夌背搴曡偉搴旈夋嫨涓夊厓澶嶅悎鑲ワ紝鍚湁姘佺７銆侀捑鍙婂井閲忓厓绱狅紝鑰岀７閰镐簩閾典粎鍚爱銆佺７銆傜帀绫...
