若使草坪提早返青,延长绿色期,可以达到更佳绿化效果。笔者经过多年实践,总结得出采取以下几点措施,可使草坪提早返青。烧荒早春(3月25日左右),草坪中的冰雪融化不久,选有微风天气趁地冻烧草。草坪烧荒后地面裸露,可接受更多的阳光,而且可以积累部分草木灰于土壤中,增加土壤中的矿物质养分,促使草坪提早返青,出苗生长旺盛。烧草要注意:①不能把草耧成堆烧。②不能使用助燃剂。③不能顺风烧,要顶风烧。松土早春草坪返青前,可用打孔叉进行松土。松土可破除土壤 If the lawn early green, extend the green period, you can achieve better greening effect. After years of practice, the author concluded that the following measures should be taken to make the lawn return to green earlier.

Lawn burned after the ground bare exposed to more sunlight, but also can be part of the accumulation of ash in the soil, increase soil mineral nutrients, prompting the lawn early green, emergence and vigorous growth. Burning grass should pay attention to: ① can not burn grass piles. ② can not use oxidizer. ③ can not wind breeze, to the wind burning. Loose soil lawn before turning green, available perforated fork for loosening. Loosening soil can be broken
