Method for mixing eucalyptuses in cupressus funebris forests in karst rocky desertification regions

Abstract

The invention discloses a method for mixing eucalyptuses in cupressus funebris forests in karst rocky desertification regions. The method includes the steps of 1, rocky desertification grade dividing,wherein the karst rocky desertification regions are divided into slight rocky desertification regions, medium rocky desertification regions and high rocky desertification regions; 2, cupressus funebris forest land selecting, wherein mature cupressus funebris forest land with the slope smaller than 70 degrees and the canopy density being 0.7 or above is selected in the karst rocky desertificationregions; 3, forest land selecting, wherein miscellaneous shrubs and weeds under the forests are fully hacked at the time one year before the eucalyptuses are planted; 4, mixing mode determining; 6, planting, wherein planting is carried out in the cloudy and rainy weather or after raining enough in spring, and one-year-old eucalyptus seedlings are used for manual seedling planting; 7, fertilizationmanaging; 8, young-interplanted-tree tending managing. The general problems that in the karst rocky desertification regions, the cupressus funebris forests are too large in density, low in wood productivity, low in cover degree of shrubs and weeds under the forests and poor in natural regeneration are solved.

Description

technical field [0001] The invention belongs to a karst vegetation planting method, in particular to a method for mixing eucalyptus in a cypress forest in a karst rocky desertification area. Background technique [0002] Southwest karst is a typical area with the largest contiguous area of ​​the three major karsts in the world and the most intense karst development. With the intensification of human disturbance, rocky desertification has become a serious ecological problem in the southwest karst region. The forest ecosystem gradually deviates from the natural state due to natural or human disturbance. The growth and succession progress of plants are restricted, and secondary forests and "little old man trees" with lack of structure, low function and poor adaptability are formed, which is not conducive to the development of regional social economy and the full play of ecological functions. The configuration and thinning of vegetation are particularly important. [0003] Cy...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a method for mixing eucalyptus in cypress forests in karst rocky desertification areas, so as to solve the problem of planting cypress trees in large areas in vegetation restoration projects in karst rocky desertification areas. Forests generally have problems of excessive density, low wood productivity, low coverage of understory shrubs and grasses, and poor natural regeneration.
