Earthen bowl of nutrition of the compression that 1 experiment process suits grafting watermelon grow seedlings to use matrix has 6cm × 2.5cm or 5cm × 2.2cm, what this we choose is 6cm × 2.5cm, smooth squeezing ramming should make seedbed copy first when grow seedlings, seedbed upper berth lies between water to use deep plastic film, in order to prevent moisture leakage and root system next plunging into, make sure nutrient earthen bowl is even and bibulous, filmy all around left and right sides of tall 6cm of bed a low bank of earth between fields, avoid prediction of a person's luck in a given year of moisture side direction.

为了培育嫁接西瓜壮苗，2005年宁海县农技推广总站和宁波市农技推广总站共同在宁海县长街镇娘娘宫村邵兴永的育苗棚内进行了"中慈"牌压缩型基质营养钵(慈溪市中慈生态肥料有限公司生产)和常规塑料钵育苗对嫁接西瓜秧苗素质影响的对比试验，现将试验结果总结如下。1试验过程适合嫁接西瓜育苗用的压缩型基质营养钵有6cm×2.5cm或5cm×2.2cm，这次我们选用的是6cm×2.5cm，育苗时要先将苗床底整平压实，苗床上铺隔水用厚塑料薄膜，以防止水分渗漏和根系下扎，保证营养钵均匀吸水，薄膜四面床埂高6cm左右，防止水分侧向流失。
