Fast-growing tree species ultra-short cutting rotation cuttage forestation cultivation method

Abstract

The invention discloses a fast-growing tree species ultra-short cutting rotation cuttage forestation cultivation method. By means of combined application of means such as improved species selection, making and treating of cuttings, planted land selection and management, cuttage forestation, final singling management, growing period management, pest control and prevention, second-year management and cutting, update nurturing after third-year cutting and fourth-year management and cutting, not only is the cutting rotation shortened to be two years, but also the yield is greatly increased, the production cost is effectively reduced, and the economic benefit is increased. By means of the method, the yield is increased to range from 1800 kilograms to 2400 kilograms per mu per year, the cost is reduced by 50 percent, and the method is specially suitable for cultivating industrial timber production forests with ultra-short cutting rotation.

Description

technical field [0001] The invention relates to the cultivation technology of fast-growing tree species, in particular to a cutting and afforestation cultivation method for fast-growing tree species with an ultra-short rotation period. Background technique [0002] At present, fossil fuels are increasingly scarce. Forestry biomass energy, as an important part of renewable energy, will become an important source of energy security due to its characteristics of non-food, environmental friendliness, carbon sequestration and emission reduction, renewable, large growth, and large resource potential. Important Guarantee. The short-rotation period cultivation mode can produce biomass quickly and in large quantities, and has great advantages in providing biomass energy raw materials such as biomass pellet fuel and cellulosic ethanol, so it has received extensive attention. At the same time, short-rotation period seedling cultivation It plays a positive role in inventions such as pr...

Problems solved by technology

[0007] Although fast-growing tree species such as poplar, willow, and eucalyptus are widely used in the cultivation of short-rotation period industrial timber forests, they generally use 1-2-year-old seedlings for afforestation, and the rotation period is 3-5 years. Generally, it is 1000-1500 kg per mu, and the biomass of ultra-short rotation period (1-3 years) is often low, so there are problems such as long rotation period, short rotation period, low yield and high cost.
