薪炭林平茬的目的,一是通过平茬促进其分蘖和生长;二是解决缺柴地区的烧柴问题。有些地区过度平茬,影响了薪炭林的正常生长。为此,应根据各树种生物学特性,有节制、讲科学,一般在种植后三年进行第一次平茬,以后每隔2—3年平茬一次。如果劳力充足,也可一年四季进行修枝,以促进薪炭林高生长。在牧区,半农半牧区及沙荒严重的农村,应采取条状轮换平茬,每次平茬的面积不得超过总面积的三分之一。平茬时间,最好是在结冻以后和解冻以前进行,以免损伤根系和薪炭林的正常生长。
The purpose of firewood stubble is to promote its tillering and growth by stubble. The second is to solve the problem of firewood burning in the area lacking firewood. Over-cropping in some areas has affected the normal growth of firewood forests. To this end, should be based on the biological characteristics of species, temperate, science, usually three years after planting for the first stubble, after every 2-3 years of stubble once. If labor is sufficient, pruning can also be carried out all year round to promote the growth of fuelwood. In pastoral areas, semi-agricultural and semi-pastoral areas and heavily deserted villages, strip rotation should be adopted. The area of each stubble should not exceed one third of the total area. Stubble time, it is best to freeze after thawing and thawing before, so as not to damage the root system and firewood normal growth.
