Construction technology of the eucalyptus plantation

High-wire loop stitch trench, trench width 1m, depth 6O ~ 80cm, using trenches to intercept the rainy season soil r West industry 2OO7.3 · Forestry Division received 40 Table runoff,[link widoczny dla zalogowanych], thereby increasing soil moisture, and promote rapid growth and canopy of eucalyptus, and improve the ability of water conservation forest in order to play a greater ecological benefits, and once and for all. This method can also be applied to other tree species plantation. Fight pits should be used for artificial slopes greater than 15. Woodland. Although the ratio of tractor behind this method, growth was significantly worse job than some of cultivated, but also to achieve the requirements of fast growing eucalyptus. Artificial playing pit site preparation specifications different from region to region and different, with a clear hole in the form Bobai forest, pit Specifications: Deep X, X on the bottom end of the 50X30X40cm more appropriate. Spacing is a spacing of plants growing eucalyptus important factor in the effectiveness of growth, according to different planting designs for different purposes. Such as cultivating small diameter wood used 2X2m,[link widoczny dla zalogowanych],. Diameter wood 2X3m or 1.5X4m,[link widoczny dla zalogowanych], excellent large-diameter timber 2X4m or 1.8X4m. Spacing should be selected from north to south as far as possible, make full use of light, to promote the photosynthesis of Eucalyptus. Select the appropriate release basal temperature and humidity, preferably 1 to March every year operation, in the original soil was full of anti-Pits slope back like a long face after the re-opening deep 18X15cm pits X, and then dedicated the main cast of Eucalyptus containing N, P,[link widoczny dla zalogowanych], Ca phosphate fertilizer 0.4kg, inspection and approval after the reunification of cast covered with soil, be careful not to reveal fat. Best before and after planting the Ching Ming Festival, adequate soil moisture, soil pit soft, easily dissolved fertilizer after planting eucalyptus seedlings are easy to absorb nutrients moisture, root sprouting quickly, the survival rate can reach # J96% or more. Seedlings to bear when the first dip in the anti-termite agents (ie, heap next to the seedling length X width X to dig deep 1.5X1X0.8m pit, filled with water and pour termite drug 5 ~ 8ml / times, you can mix .) 2cm too Cup Baptist appropriate elbow, not dipped seedlings leaves, dip of about 1 to 3 minutes, drip dry to dry, and then up the hill planting. Attention must be removed when planting nutrition Cup lost pit, the soil should not Nongsan Cup. Colonization of the direct use of dedicated open pit planting hoe, seed and asked the nursery to keep upright, dirt overshadowed Cup appropriate 2-3cm of soil, compacted fill to make some. Check the survival time after planting, replanting and timely conduct of Simiao pit. 3. Fertilization tending tending the year, that planting 1 to 21 months, tending to bring Ken (Artificial play pit for some). Specific plants for the center line is, on the bottom of the reclamation of wide 75cm, depth 15-20cm, mud pie, and flip the ribbon connected with the shrub head, Mount excavation out to stump other band, so neither causes soil erosion, but also greatly enhance the absorption of nutrients, more conducive to the rapid growth of eucalyptus. Two or three years has been bringing up this point the basic canopy of eucalyptus, and the height is between the 6-12m. Tending determined based dressing, if cultivated with the mixed shrub health, have difficulty with dressing a certain repairs, the Pits below 0.3 meters, 0.7 meters above the cut complex irrigation repair, and even into the band, leaving the wood grass head at 0.1 meters. Fertilizer pit open position to the lawn surface 50X50cm, to speed up the fertilization rate and improve the efficiency of Eucalyptus absorb fertilizer nutrients. Topdressing fertilizer the first year of the development of eucalyptus leaves and roots of the long-based, should focus on fertilizer containing N, P-based fertilizers, especially N. Bobai forest with their own R & D base fertilizer (calcium and magnesium phosphate), the basal release in the form of 0.4Kg / pit. After planting 3O ~ 4J. Select cloudy days, temperature, humidity, weather cast a more appropriate to N, P, K-based compound fertilizer. Specific operation on both sides in the plant under the drip line of open pits, pit size for the long 18cmX deep 15cm, cast fertilizer 0.25Kg / pit, covered with earth pressed flat a week after fertilization was tall eucalyptus, green leaves, roots change thick, is a clear sign of fertilization in place. The next year is the rapid growth of thousands of materials of the physical transformation and fertilization should be based on D, avoiding excessive, resulting in leggy branches. Time of the spring election on the basis of bringing in the cast of urea fertilizer 0.05kg + O. 5kg g / plant. The third year is the fastest accumulation of stem biomass at most of the time, suggested a large number of fertilization, is still the main PK, Shi 2kg / plant fertilizer to extend the peak production of thousands of materials, materials in order to achieve higher rates of high purpose. 4. Prevention and control of pests and diseases of Eucalyptus based mainly on diseases, including bacterial wilt, shoot blight and leaf spot. Forest production should be done in the early detection, early prediction, early prevention,[link widoczny dla zalogowanych], in a timely manner to clean up diseased plants, with forest defense, sight personnel to effectively control virus and prevent disease spread. Patient's condition is well controlled, can guarantee the eucalyptus plantation to minimize loss, and is able to effectively vacant Pits replanting, greatly promoting the growth of Eucalyptus forests with high survival.
