需肥规律每生产1 000kg大蒜,需吸收氮5.1kg、磷1.3kg、钾1.8kg,其养分吸收比例为3.92:1:1.38。基肥大蒜根系浅,根毛少,吸收养分能力弱,对基肥质量要求较高。施用前,要使有机肥充分腐熟,并将其捣碎拌匀,以防止未腐熟的生粪导致蒜蛆为害。常用的农家肥有人粪尿、猪粪尿,鸡、鸭粪和饼肥等。一般每667m2施用猪粪尿2 500~3 000kg。用化肥做基肥的,每667m2施硫酸铵30~35kg,或尿素10~15kg,将肥料施 Need to fertilizer law Each production of 1 000 kg garlic, need to absorb nitrogen 5.1kg, phosphorus 1.3kg, potassium 1.8kg, the nutrient absorption ratio of 3.92: 1: 1.38. Basal garlic root shallow, less root hair, nutrient absorption capacity is weak, the higher the quality of the base fertilizer. Before application, make full maturity of organic fertilizer, and mashed and mix well, in order to prevent unhealthy raw manure lead to garlic maggot damage. Manure commonly used manure, pig manure, chicken, duck manure and cake and so on. General pig manure per 667m2 2 500 ~ 3 000kg. Fertilizers do basal fertilizer, ammonium sulfate 30 ~ 35kg per 667m2, or urea 10 ~ 15kg, fertilizer application
