1 建立苗床选择排灌条件好,肥沃的壤土或砂壤土作为育苗场地。苗床面积根据定植面积确定,一般1hm~2需苗床450m~2,宜采用2m×8m育苗畦。首先将表土层10～15cm起出备用,再将下层土(15～30cm)挖出叠塄埂,然后把起出的表土层回填摊平。施腐熟有机肥2.5～3.0kg/m~2,尿素15.0g/m~2,磷酸二铵30.0g/m~2,将这些肥料均匀地渗入土中,拌匀、耙平、整细后浇透水。
1 to establish seedbed selection Drainage conditions are good, fertile loam or sandy loam as a nursery grounds. Seedbed area is determined according to the planting area, generally 1hm ~ 2 need seedbed 450m ~ 2, should adopt 2m × 8m nursery 畦. First, topsoil 10 ~ 15cm off reserve, and then the lower soil (15 ~ 30cm) dredged stacked 塄 埂, and then out of the top soil leveling backfill. Apply organic fertilizers 2.5 ~ 3.0kg / m ~ 2, urea 15.0g / m ~ 2, DAP 30.0g / m ~ 2, evenly infiltrating these fertilizers into the soil, mix well, rake flat, permeable.
