Problems solved by technology

Although container-grown saplings can avoid the main root damage caused by bare-ground seedlings, they will have a coiled root system. Once the coiled root system becomes lignified, this root system will continue to maintain, making the roots of container seedlings move. After planting, it can only grow in the direction of coiling, and it is difficult to penetrate deep into the soil
[0004] Use bare-root seedlings or container seedlings to transplant afforestation on flat land or places with thick soil layers. Because the soil conditions are relatively good, even if the main r

Embodiment 1

[0058] 1. Preparation of soil pillar blocks and cultivation of soil pillar seedlings

[0059] Fully mix the soil and compost at a volume ratio of 6:4, add fertilizer at a rate of 50 grams of diammonium phosphate (64%) per 70 liters of mixed material, and then gradually add water to the material. The amount of water should be based on the clay and The water content of the straw compost increases or decreases. The reference standard is: hold the mixed material tightly with your hand and then loosen it, and the material can disperse automatically. Use a special mold to press the material into a cylindrical hollow soil block 1, the soil column block 1 has an outer diameter of 9 cm, an inner diameter of 3 cm, and a height of 11 cm, and then the soil column block 1 is placed in a shaded place for 2-3 days. After the block is slightly dry, fill the hollow of the soil column with nutrient soil 2 (mixed with clay, straw compost and peat at a volume ratio of 5:3:2). Sow the forest tree...

Embodiment 2

[0064] Embodiment 2: Coniferous tree seedlings are prepared and seedling-raising with soil column block

[0065] After mixing clay, straw compost, diammonium phosphate (64%), and water, molds are used to form a soil column block 5 for coniferous tree seedlings. The volume ratio of clay to compost is 6:4, and the addition ratio of diammonium phosphate (64%) is 0.7 grams of DAP (64%) was added to 1 liter of clay and compost mixture. The amount of water should be increased or decreased according to the moisture content of the clay and straw compost. The reference standard is: hold the mixed material tightly with your hand and then loosen it, and the material can disperse automatically.

[0066] Coniferous tree seedling is 12 centimeters with the external diameter of soil column block 5, and the internal diameter of soil column block is 5 centimetres, and the height of soil column block is 20 centimetres. Coniferous saplings will be wrapped with barbed wire 6 with the appearance ...

Abstract

The invention relates to a method for soil-column seedling culture and transplanting afforestation, wherein the transplanting afforestation method comprises the following steps of preparing soil-column blocks, using the soil-column blocks to cultivate tree/shrub seedlings and transplanting soil-column-block seedlings on site. The method can avoid the damage of bare-rooted seedling transplantation to tree root systems, as well as the problem of root-system coiling problem caused by container seedling transplantation, can enable transplanted seedlings to form root-system forms similar to self-generated trees so as to improve the survival rate of the seedlings and the adaptability of the seedlings to new environments, can avoid the destruction of fish-scale pits and other traditional afforestation methods to ground surface, and can reduce soil wind erosion. The method can be used for general flat-land afforestation, as well as slope-land, sandy-land and wasteland afforestation, and has obvious social, economic and ecological benefits.

Description

technical field [0001] The invention relates to a method for growing seedlings and a method for transplanting and afforestation, in particular to a method for afforestation of soil pillar blocks and soil pillar seedlings suitable for raising tree seedlings under harsh site conditions. Background technique [0002] Traditional tree seedling raising methods for transplanting can be divided into bare ground seedling raising (bare root seedlings, soil ball seedlings) and container seedling raising (container seedlings) two categories. [0003] Generally speaking, the root system of naturally growing trees is characterized by well-developed main roots, few but relatively thick lateral roots, and the overall shape of the root system is thick, long, sparse, and networked. This kind of root system can penetrate deep into the soil and has a wide distribution. It not only plays a major role in supporting the weight of trees, but also holds the soil and reduces soil erosion. However, ...
