为筛选适合我国国情的芒草产业化的低成本繁殖技术,根据国外相对成熟的种植措施,利用我国的农业生产数据,对5种可行繁殖技术的后代种植成本进行估算。结果表明:5种繁殖系统的后代材料在种植密度、除草剂类型及施用量、施肥量存在差异最大;估算种植成本变异幅度为3 072.0~12 225.3元/hm2,其中种子直播法成本最低,而微繁育苗移栽法最高;在各项投入要素中种植材料与化肥的成本最高,合计约占总体生产成本的70%。此外,还利用SWOT法对5种繁殖技术的利用潜力予以评价。结果表明:在芒草产业化的初期,根茎直播法将被广泛采用;随着技术的进步,根茎与茎秆育苗移栽法将会逐步取代根茎直播法;最后,种子直播法与微繁育苗移栽法将会主导芒草的商业化生产市场。 In order to screen low-cost breeding technology for the industrialization of misc grass in our country, according to the relatively mature planting measures in foreign countries and using the data of agricultural production in our country, the cost of planting offspring of 5 feasible breeding techniques was estimated. The results showed that there were significant differences in the planting densities, herbicide types, application rates and fertilization rates among the five breeding systems. The estimated variation in planting cost ranged from 3 072.0 to 12 225.3 Yuan / hm2, of which the seed direct seeding method had the lowest cost Micropropagation seedling transplanting method is the highest; the highest cost of planting materials and fertilizers among various input elements, accounting for about 70% of the total production cost. In addition, the potential of five breeding techniques was evaluated using the SWOT method. The results showed that in the initial stage of Momi industrialization, the method of direct seeding of rhizomes would be widely adopted. With the advancement of technology, the transplanting of rhizomes and stems would gradually replace the direct seeding of rhizomes. Finally, Cultivation method will dominate the Maucao commercial production market.
