What should be noted when planting eucalyptus? Netizens, please help introduceThe following points should be noted when planting eucalyptus:
1. Selection and leveling of the planting site:
Choose well-drained terraces, hills, gentle slopes, and sites with deep, loose soil for afforestation. First cut down weeds and clear the land, then burn the cleared vegetation, prepare the land 3 months before afforestation, and refill the pits.
For afforestation sites with a slope below 6°, full ploughing by machine can be used, with a depth of 30 cm; for hilly land with a slope between 7 and 10°, strip ploughing by machine can be used;
For hilly forest land with a slope between 10 and 15°, trenching along the contour direction or digging large pits can be used for land preparation; after planting and afforestation, strip loosening of the soil along the planting rows should be carried out for tending;
For mountainous land with a slope above 15°, digging large pits along the contour direction is suitable for land preparation. The better specification is 60 cm (top width) × 40 cm (depth) × 40 cm (bottom width). After planting and afforestation, strip loosening of the soil along the planting rows should be carried out for tending.
2. Eucalyptus planting] density:
For the purpose of cultivating pulpwood, a row spacing of 3 m × 2 m or 4 m × 2 m is suitable, with a planting density of 83 to 111 trees per mu. If the purpose is to cultivate medium- and large-diameter timber, the row spacing should be 5 m × 2 m or 4 m × 3 m, with a density of 56 to 67 trees per mu.
3. Fertilization methods for eucalyptus:
Apply sufficient base fertilizer before afforestation, mainly phosphate fertilizer. Apply 0.25 kg of phosphate fertilizer (content 18%) and 0.15 kg of compound fertilizer (content N15%P15%K15%) per pit, plus 8.1 g of borax, 4.1 g of copper sulfate, and 4.5 g of zinc sulfate. First put the fertilizer into the pit and mix it evenly with the topsoil, then refill until it is about 5 cm higher than the ground surface.
4. Selection of eucalyptus seedlings:
Use excellent clonal tissue-cultured seedlings or cutting seedlings in nutritional cups. The seedlings should be placed in a cool place, and attention should be paid to watering to maintain moisture.
5. Suitable planting time for eucalyptus:
Planting from March to May is suitable, and it should be carried out on cloudy and rainy days or when the soil is moist. Dig a planting hole in the center of the pit, completely remove the plastic bag outside the seedling's nutritional cup, place the seedling into the hole, straighten the seedling, then fill in fine soil and compact it (be careful not to damage the roots), then cover with another layer of fine soil up to 2 cm at the seedling's root collar. If the weather is dry with no rain, it is necessary to water thoroughly to settle the roots.
Daily management methods for eucalyptus:
1. Replanting: Check the survival rate one week after afforestation, and immediately replant any that have not survived.
2. Tending: In March to April of the first and second years after afforestation, carry out weeding, soil loosening, and expansion of the pits along the tree rows once each.
3. Topdressing: Generally topdress 2 to 3 times. Dig small pits or apply fertilizer in strips 50 cm to 80 cm away from the tree roots. It is best to use compound fertilizer (content N15%P15%K15%), and the fertilizer must be covered well.
The first topdressing (one month after planting): 0.3 kg per plant; the second topdressing (March to April of the second year): 0.4 kg per plant; the third topdressing (March to April of the third year): 0.3 kg per plant.
