短轮伐期集约经营是目前国内外解决木材短缺的有效方法。其特点是选用较好的立地,利用良种壮苗、密植,实行农林间作,采用配套的农业技术措施,在短轮伐期内获得高产的生物量。国外近年正在探索一种超短轮伐期集约栽培方法,密植的杨树1—5年即可获得高产,其产品用于生产各种人造板、造纸、燃料和饲料。 Short-cycle intensive management is an effective way to solve the shortage of wood at home and abroad. Its characteristics are the selection of a better site, the use of seedling strong seedlings, close planting, the implementation of intercropping with agriculture, supporting the use of agricultural technology measures to obtain high-yield biomass in the short-rotation period. In recent years, foreign countries are exploring an intensive cultivation method for ultra-short rotations. Poplar trees with dense planting can obtain high yields in 1-5 years, and their products are used in the production of various kinds of wood-based panels, papermaking, fuel and feed.
