聚合草又称爱国草。近年来,在市郊种植结果表明,它确实具有产量高、适口性好,适应性强、容易繁殖、管理方便、病虫害少、鲜用期长、可以青贮等优点,深受群众欢迎。目前,立春已过,应该抓紧聚合草的春繁工作。田间自然越冬的聚合草根,于3月上、中旬就会陆续萌芽,长出新叶。因此,2月上、中旬即可进行聚合草的人工繁殖工作,将老根从土中掘起,按切根繁殖法和根颈部纵切繁殖法育苗,做到早种植,早收获、早利用。现将这两种繁殖方法介绍如下: 一、切根繁殖法。聚合草的肉质根发 Polymerization grass, also known as patriotic grass. In recent years, planting results in the suburbs have shown that it does have the advantages of high yield, good palatability, adaptability, easy breeding, convenient management, less pests and diseases, long fresh life, and can be silaged. At present, the beginning of spring has passed, should pay close attention to the polymerization of grass spring work. In the field of winter, the aggregate grassy roots naturally begin to sprout in mid-March and grow new leaves. Therefore, in February, the artificial grass can be carried out polymerization breeding work, the old root from the soil to dig up, according to the root-cut propagation method and vertical propagation of law nursery stock, early planting, early harvest, early use. Now these two breeding methods are as follows: First, the root-cutting propagation method. Aggregation of grass fleshy root hair
