目前,黄瓜嫁接栽培已成为发展深冬黄瓜生产的重要措施。为了提高嫁接成活率,我们在临淄区葛庄村进行了实验,改营养土为沙子育苗。结果表明,因沙子通风透气好,有利于幼苗根系的生长发育,并可避免嫁接提苗时伤幼根,增强了嫁接后根系的生活能力,比一般育苗法育出的苗高5%,生长健壮,成活率达到95%以上。一、育苗方法10月中下旬,在大棚内,挖深6～7厘米的坑(宽和长视育苗多少而定),坑底部和四周铺好塑料薄膜,把沙子均匀放入坑内,使沙面离地面1～1.5厘米。然后将浸种催芽的黄瓜和南瓜种子分别播入坑内,再均匀覆沙1～1.5厘米,喷透水,盖上小拱棚。棚内夜间温度保持16
At present, cucumber cultivation has become an important measure for the development of winter cucumber production. In order to improve the survival rate of grafting, we conducted an experiment in Gezhuang Village, Linzi District, and changed the soil for sand nursery. The results showed that the good aeration and ventilation of sand could promote the growth and development of seedling roots and avoid the injury of rootlets during grafting, which enhanced the viability of root system after grafting, which was 5% Robust, survival rate of 95% or more. First, nursery methods In late mid-October, in the greenhouse, dug deep 6 ~ 7 cm pit (width and length depending on nursery), the bottom of the pit and the surrounding paved plastic film, the sand evenly into the pit, the sand Face 1 to 1.5 cm away from the ground. Then soaked seed germination of cucumber and pumpkin seeds were sown into the pit, and then evenly covered with sand 1 ~ 1.5 cm, spray water, covered with small shed. Night temperature in the shed to maintain 16
