一、化肥秋施好处 1、结合秋翻、打垄或破垄夹肥,能够把化肥施入15厘米深的土层、减少氮肥挥发损失,有利于作物根系吸收利用,达到增产目的。试验表明,亩秋施尿素30公斤,比春施增产16.2%;亩秋施尿素10公斤做底肥的玉米,比夏季追肥的增产16%,高粱增产22%;亩秋施碳铵30公斤做底肥的玉米,比苗期追肥的增产10%,小麦增产11%。 First, the benefits of chemical fertilizer autumn 1, combined with the autumn turn, ridge or broken ridge clip fertilizer, fertilizers can be applied to 15 cm deep soil, reduce nitrogen loss of volatile, is conducive to crop root absorption and utilization, to achieve the purpose of increasing production. Tests show that 30 acres of autumn urea urea, spring yield increase than 16.2%; mu fall urea 10 kg of corn to make base fertilizer, than the summer topdressing 16% yield, sorghum yield 22%; mu autumn ammonium bicarbonate 30 kg to make base fertilizer Of corn, 10% more yield than the top seedling, wheat yield 11%.
