播种果树砧木种子用地膜覆盖具有保湿省水、提高地温、提高出苗率的良好效果,采用地膜覆盖必须注意以下几点。 一、做畦不可太长。畦长了地膜易兜风破裂使畦内失墒。一般整成7—8米长,1米左右宽的畦为宜。覆膜前必须把畦面整平,畦土细碎无坷垃再覆膜。覆膜时应当将地膜拉紧、铺平,四边开好沟将地膜埋入压实,使地膜与畦面紧贴。
Seeds of fruit trees stocking rootstocks covered with plastic film with moisturizing water, raise ground temperature, improve the germination rate of the good results, the use of plastic film coverage must pay attention to the following points. First, do not be too long.畦 long easy to ride a plastic film to break the wind 畦 within the loss of moisture. Normally integrated into a 7-8 meters long, about 1 meter wide 畦 appropriate. Laminate must be flattened before the surface, fine soil crushed without rubbish and then covered with film. Lamination membrane should be tightened, paved, open a good ditch on both sides of the film will be buried in the compaction, so close to the surface film and noodles.
