一、整地与施肥胡萝卜入土深,吸收根的分布也较深,又因种子小,发芽困难,所以整地要求深耕20—25厘米,使土壤疏松、细碎、平整。结合深耕施入腐熟细碎的有机肥,施未腐熟的基肥或施肥不均匀都会形成畸形。化肥底肥施用二铵10公斤、硫酸钾每亩10公斤。胡萝卜需氮、钾肥较多,磷肥次之。钾肥能促进根部形成层的分生活动,增产效果显著;磷肥有利于养分运转,增进品质;氮肥是构成植物体和产品的基本物质。二、播种 1.播种期:选用日本新黑田五寸参品种生育期为100天,播种
First, soil preparation and fertilization carrot deep into the soil, the absorption of root distribution is also deeper, because of the small seeds, germination difficulties, so the preparation of deep plowing 20-25 cm, so that the soil loose, crushed, smooth. Combined with deep plowing into the rotten fine organic fertilizer, Shi Fu maturity of the base fertilizer or fertilizer will form a deformity. Fertilizer fertilizer diammonium 10 kg, potassium sulfate 10 kg per mu. Carrot nitrogen, potassium more, followed by phosphate. Potassium can promote the formation of the root formation of the meristematic activity, yield significant effect; phosphate fertilizer is conducive to nutrient operation, improve quality; nitrogen fertilizer is the basic material constituting plants and products. Second, sowing 1. Sowing period: Selection of Japan’s New Kurotian five inch varieties of growth period of 100 days, sowing
