稻套小麦撒播较好地解决了水稻晚熟,小麦推迟播期的矛盾。但是对稻套麦撒播也存在以下错误的认识和做法: 一、播期过早,播量过大 有些农民错认为稻套麦撒播出苗慢,麦籽损失多,出苗少。所以播期提早再提早,播量也相应加大,有的“秋分”甚至“白露”刚过就撒播,每667平方米播量加大到17.5公斤以上。由于此时气温高,湿度大,小麦出苗生长发育快,稻麦争水、争肥、争阳光。又由于稻高麦低,小麦根浅而少,不分蘖,麦苗呈现细、弱、高、黄、瘦,
Rice sowing wheat broadcast sowing a better solution to the late maturity of rice, wheat delayed sowing contradictions.
