上黄试区草地资源与评价
- Title:
- Study on Productivity of Shrubberies in Loess Hilly Region of South Ningxia
- 摘要:
- 本文通过对上黄试区草地植被群落特征特性的分析比较，研究其自然特点和生产性能.以求有效地利用和进一步合理地培育草地，为在本区畜牧业发展和综合治理中充分发挥其作用.研究结果表明，本区天然草地可划分为2类（干草原、灌丛草原），6组，36型.主要植物167种，分属41科，85属.其中饲用植物132种，占植物总数的79.0%，有毒有害植物35种，占21.0%.现有天然草地年可提供鲜草32.22×104kg，人工草地可提供8.95×104kg，秸秆可提供78.52×104kg，乔灌木树叶可提供9.3×104kg，全年本区可提供鲜草、秸秆、树叶共128.99×104kg，载畜1842.6个饲养量，就目前1858个饲养量，略有超载.如何解决这一问题，本文主要从改良天然草地和发展人工草地方面进行了分析讨论.
- Abstract:
- Through analysing and contrasting the characters of grassland vegetation and aiming at efficient use and rational cultivation of grassland, the author study its natrual features and produetive forces.The study results shown: The natural grlassland could be divided into two sorts (arid grassland, shrub grassland), six groups which included 36 styles.There are 167 species of main plants which belong to 41 family, also 85 generas in the field.Among those, 132 species were used as forge which counted for 79.0% of total, and other 35 species were toxicty or harmful.At present, the natural grassland could produle fresh grass yearly 32.22×104kg, and artificial grassland provide 8.95×104kg a year.Straw of crops give yearly 78.52×104kg of forge.The leaves of forests and shrubs are 9.3×104kg a year.The total forge of the region reach at 128.99×104kg/a.which could bring up 1 842.6 sheep.Now, there are a large shortage of forge for 1858 sheep.To solve the problem, the author analysed and discussed in two aspects: one is to improve natural grassland, the other is to develop artificial grassland.
