1. an earth pillar transplantation of seedlings method of forestation, the method comprises cultivates Qiao, shrub seedling and earth pillar seedling is transplanted on the spot by the method that the forest tree seed of earth pillar piece is grown seedlings;

  • The forest tree seed seedling-cultivating method of described earth pillar piece comprises the steps;

    Step 1;

    seedling nutritious soil inserted in earth pillar piece hollow under greenhouse and sowed earthing;

    Step 2;

    water and ensure that seedling nutritious soil is all the time in moisture state;

    Step 3;

    after seed sprouting, form earth pillar seedling, by liftoff earth pillar seedling built on stilts placement, terrain clearance 10-15cm, earth pillar piece bottom is in drying regime;

    Step 4;

    in the time that seedling height reaches 5-10 centimetre, seedling is outdoor by moving in greenhouse or plastic tunnel, outdoor daily mean temperature will be 15 DEG C of left and right;

    Wherein, described earth pillar piece is cylinder type hollow soil block, earth pillar piece is to adopt mould compacting to form after being mixed by clay, straw compost, 64% diammonium phosphate, water, the volume ratio 5-7;

    3-5 of clay and compost, the adding proportion of 64% diammonium phosphate is to add 0.6-0.9 gram of 64% diammonium phosphate in the clay of 1 liter and compost mixture;

    Described earth pillar seedling on the spot transplanting method comprises the steps;

    Step 1;

    place is transplanted in cleaning, removes weeds and rubble;

    Step 2;

    get downward vertically diameter 18-20 centimetre, the heatable adobe sleeping platform of degree of depth 40-50 centimetre, broad-leaved tree earth pillar seedling use, the heatable adobe sleeping platform diameter 22-25 centimetre that coniferous tree earth pillar seedling is used, degree of depth 50-60 centimetre at transplanting point;

    Step 3;

    sprinkle 1-2 gram of 64% diammonium phosphate in heatable adobe sleeping platform bottom, then fill water in hole;

    Step 4;

    sprinkle water-loss reducer and compoiste fertilizer along heatable adobe sleeping platform surface, water-loss reducer consumption is 0.1-0.2 liter, compoiste fertilizer consumption 20-30 gram;

    Step 5;

    after underground water has oozed, the water-loss reducer on heatable adobe sleeping platform surface, compoiste fertilizer are shoveled into heatable adobe sleeping platform together with table soil, the degree of depth of banketing, for the near coal-mine 10 centimetres of left and right of distance, then stirs table soil, water-loss reducer, compoiste fertilizer in heatable adobe sleeping platform;

    Step 6;

    pour appropriate water into, the table earth mixtures in hole is stirred into mud;

    Earth pillar seedling is inserted among the interior mud in hole, and mud will not just be entered at the top of earth pillar piece;

    Step 7;

    at mud surface coverage Material of preserving soil moisture, then at the dry ground of 2-3 centimetre of thickness of Material of preserving soil moisture surface coverage;

    Step 8;

    finishing heatable adobe sleeping platform periphery physical features makes it to become gradually skewed to heatable adobe sleeping platform mouth, has then repaiied at heatable adobe sleeping platform periphery the earth cofferdam that diameter is 1 meter of left and right, high 10 centimetres of left and right, and cofferdam opening is towards the higher part of physical features;

    Step 9;

    cofferdam is fixed and filled water in cofferdam afterwards, after water infiltrates completely, the soil of loose earth pillar shoot root portion.
