稻草还田是有机肥建设的一项重要内容,有改善土壤理化性状、提高土壤有机质含量、增加钾素养分、减轻病虫危害、促进晚稻高产和冬种作物生长的作用。鲜稻草还田的技术要点:一是稻草还田应与碳铵深施相结合。在稻草还田时每667平方米深施15～20公斤碳铵,以增加土壤中的氮素,避免发生土壤脱氮现象而影响晚稻生长,促进晚稻早回青分蘖。但施用碳铵时应
Rice straw returning is an important part of the organic fertilizer construction. It has the functions of improving soil physical and chemical properties, increasing soil organic matter content, increasing potassium nutrient, reducing pests and diseases, and promoting high yield of late rice and winter crop growth. Fresh straw back to the technical points: First, straw should be combined with ammonium bicarbonate deep application. Straw in the straw every 667 square meters deep application of 15 to 20 kg of ammonium bicarbonate to increase nitrogen in the soil to avoid the phenomenon of soil denitrification affect the growth of late rice and promote early maturing late rice tillering. However, the application of ammonium bicarbonate should be
