饲料林,是以生产枝叶供性畜采食为主要目的的林种。由于木本植物寿命长,植丛大,对当年降水依赖性低,残留时间长,因此,在提供枝叶量方面的年、季度变幅小。这对解决干旱年份和枯草期供草量不平衡的问题,有重大的实用价值。营造饲料林,首先要有一个合理的规划,应把荒漠、荒漠草原和部分干旱草原列为发展饲料林的重点地区。这些地区,又应把饲料林作为扩大草场、改良草场的重要内容。其他地区,也要适当营造一些饲料林。但这种饲料林,主要是作为备荒草
Feed forest, is based on the production of foliage for animal feed for the main purpose of forest species. Due to the long life of woody plants, large vegetation, low dependence on the current precipitation, the residual long time, therefore, in terms of the amount of foliage provided in the small quarter amplitude. This is of great practical value to solve the problem of imbalance of grazing in dry years and hay. First of all, to create a feed forest, there should be a reasonable plan. Deserts, desert steppes and some dry grasslands should be listed as key areas for the development of feed forests. In these areas, feed forests should also be used as an important part of expanding grasslands and improving grasslands. In other areas, some feed forests should also be properly constructed. However, this feed forest, mainly as a waste grass
