Yard Work: When People Choose Sod Over Seed

This is the VOA Special English Agriculture Report.
For some people, the road to immediate satisfaction is laid with sod. A piece of sod has grass on the top and soil on the bottom. It can provide thick green grass without the work or wait required to grow a lawn from seed.
A worker lays sod in Wrigley Field in Chicago during improvements made in 2007
Some property owners are replacing grass with ground covers that require less care and water. But others want a traditional grass lawn. Sod, or turf, might not seem like a farm crop. But farmers grow it around the world for everything from homes to sports fields.
Sod farmers often grow different grasses for different conditions. Farmers must cut, fertilize and water the sod often. The crop may not be ready for up to two years. Farmers harvest it in pieces of various lengths and up to one meter wide.
Making the best of sod takes work. Preparing the ground to lay sod is important and may require soil amendments.
David Robson from the University of Illinois Extension says the best results come from moist, richly organic black soil. He says that is because the farmer used rich soil to produce the sod, so it might not do well in clay soils.
Some gardeners prepare an area by removing the existing top soil and grass. This can be done with a shovel, hoe or sod-cutter machine. But live roots or weeds might remain below the surface.
Another preparation method is to till the ground completely. Still another involves using an herbicide chemical to kill the existing grass. Sod can also be placed over existing grass. The grass will die and become fertilizer for the sod.
After sod is in place, it needs to be pressed down firmly. This will remove air pockets and help the sod make contact with the ground and take root. A water-filled drum called a sod roller can be used.
Sod can grow at times and in places where growing grass from seed is difficult. But sod can also have problems, especially if it was not very fresh. Newly laid sod needs water -- lots of water. It can quickly become dry. It will need water two times a day for at least three months. Sod should also be fertilized. And it should be treated with limestone if the soil is acidic.
Sod can be cut to fit a space. But small pieces should not be placed along the edges of an area as they can dry out more quickly.
You can find other advice online. For example, we learned that sod should not be placed so that the ends of the pieces are all in a line. Instead it should look like a brick pattern on a building.
And that's the VOA Special English Agriculture Report, written by Jerilyn Watson. I'm Bob Doughty.

这里是VOA 特别英语农业报道。
铺草皮可以直接满足有些人的需求,草皮的上面是草,底部是沙土。有了它,无需劳作,也不用等着种子长成草坪,就可以收获一片浓浓的绿意。
有的业主用地面覆盖物取代草地,这样就不用照看和浇水了。但是有的人还是喜欢传统的草坪。草皮和草坪或许不像传统的农场作物,而全世界的农场主们都在种它,无论是用在家庭园艺,还是用于运动场地。
草坪种植者通常在不同的场地种植不同的草,他们必须经常对草皮进行修剪、施肥、浇水。草皮在两年内是长不成形的,农场主们收割草皮时,把它们割成长度不一、宽度一米的草块。
种好草皮很费力气,准备好田地很重要,还要施以肥料。
伊利诺斯州推广大学的David Robson说,湿润、富含有机肥的黑土可以培养出最好的草皮。他说,这是因为农场主们用肥沃的土壤培育草皮,所以粘土可能不行。
有的园艺者开辟田地时,移去表层的土壤和杂草,这个可用铲子、锄头或草皮收割机,但是活的根和草籽可能会在地下保留着。
另一个开辟的办法是把土壤彻底翻一遍,还可以用除草剂去除活着的杂草。也可以在杂草上种植草皮,杂草便会死亡,成为草皮的养料。
草皮种好后,要用力压压。这可以把草皮与土壤之间的空气驱走,使草皮与土壤充分接触并生根。可用一种叫草皮滚轮的充水锤子来压草皮。
当您发现在有的时机和地点,要想把种子培育成草坪很难,这时您可以种草皮。但是草皮也有它的麻烦,特别是,如果草皮不够新鲜。刚种下的草坪需要浇水--大量的水。草皮很容易变干。在最初至少三个月里,每天要浇两次水。还要对草皮进行施肥,如果土壤酸度过大,还要施以石灰。
可用草皮来弥补空缺,但是小片的草皮不能放在空地的边缘,因为它们会很快干枯。
你可以在网上找到其他的建议,比如,我们了解到,不能这样种草皮,即:使草皮块的末端排成一条线,而应像建筑物上的砖头那样交错排列。

【参考译文】有的业主用地面覆盖物取代草地,这样就不用照看和浇水了。
【难句解析】replace A with B, 意思是“用B来取代A”,“that require less care and water”是定语从句修饰“ground covers ”。
2.After sod is in place, it needs to be pressed down firmly. This will remove air pockets and help the sod make contact with the ground and take root. A water-filled drum called a sod roller can be used.
【参考译文】草皮种好后,要用力压压。这可以把草皮与土壤之间的空气驱走,使草皮与土壤充分接触并生根。可用一种叫草皮滚轮的充水锤子来压草皮。
【难句解析】"in place"的意思是“在适当的位置”,“air pocket”意思是“ 气包”,"make contact with"的意思是“与...接触”。
