人工草地的轮作即饲料轮作,在草原地区最好有林网防风保护,因此也称林网草田轮作。它与大田轮作不同,主要目的是为牲畜提供高产、优质的饲草、饲料,而改良土壤结构、恢复与提高土壤肥力是次要的目的。因此,牧草种植的年限较长,面积较大,而粮食及经济作物栽培年限较短,面积也较小。一、轮作的概念及作用在牧草及作物栽培过程中,人们有意识地将计划种植的不同牧草、作物,按它们的特性和对土壤与后茬的影响,排成一定的顺序,在一定的田块上依次地周而复始地轮换种植,即称为轮作。
The rotation of artificial turf that feed rotation, the best grassland in the forest network wind protection, it is also known as forest network grass field rotation. It is different from the field rotation, the main purpose is to provide livestock with high yield, high quality forage, feed, and improve the soil structure, restore and improve soil fertility is a secondary objective. As a result, pasture cultivation has a longer duration and a larger area, while food and cash crops have a shorter cultivation period and a smaller area. First, the concept of rotation and the role of In the forage and crop cultivation process, people consciously planned planted different forage, crop, according to their characteristics and the impact of soil and the stubble, arranged in a certain order, in a certain field In turn, the block rotation planted in turn, known as the rotation.
