Problems solved by technology

These two methods have the following problems. One is that the soil ball will destroy the cultivation layer of the cultivated land, and the cultivation cost of the container seedling is high; the other is that the weight of the soil ball or the container substrate accounts for 30-50% of the weight of the whole sapling, and the volume increases by 5-15%. , the transportation cost is 30-50% higher than that of bare-root seedlings. In southern mountain fields, the mountains are generally high and the roads are steep, and the cost of short-calling is high, especially for saplings with a diameter of 6 cm. The third is that the soil ball seedlings are easily damaged during the transportation process. After the soil ball is damaged, it loses its protective effect on the root system, causing root damage and tree dehydration.

Embodiment 1

[0026] Example 1: Afforestation test tree species: hackberry

[0027] The selected 240 hackberry trees with a ground diameter of 6-8cm are centered on the tree stem and 6 times the diameter of the seedling ground, and the saplings are dug out in a spherical shape. All the saplings are cut off the pole at a height of 3.5m and pruned, of which 30 are Pick up the soil balls and wrap them with cloth tapes; after the other 210 plants are taken out, use a high-pressure water pump to flush out the soil at the roots, 180 plants are soaked in the creek for 3-5 hours, and the other 30 plants go directly to the mountains for afforestation. The methods and survival rate survey results are shown in Table 1. The size of the planting hole is 80 × 80 × 50 cm. When planting, first backfill the topsoil in the center of the hole 15 cm to the shape of a steamed bun, insert the taproot of the sapling into the topsoil of the steamed bun, and continue to backfill the soil to 25 cm. Use a wooden stic...

Embodiment 2

[0031] Embodiment 2: Afforestation test tree species: Zhejiang camphor

[0032] The selected 300 zhejiang camphor trees with a ground diameter of 4-5cm are taken as the diameter of 7 times the ground diameter of the seedlings, and the saplings are dug in a spherical shape. All the saplings are cut off and trimmed at a height of 2.8m, and 30 of them are in the way of soil balls. It is good to use cloth tape to wrap it up; after the other 270 plants are lifted out, use a high-pressure water pump to wash away the soil at the roots, 240 plants are soaked in the creek for 1.5-3 hours respectively, and the remaining 30 plants go directly to the mountains for afforestation. For specific treatment methods and results, see Table 2. The size of the planting hole is 50 × 50 × 40 cm. When planting, first fill the topsoil in the center of the hole 15 cm to the shape of a steamed bun, insert the main root of the sapling into the top soil of the steamed bun, and continue to backfill the soil...

Embodiment 3

[0036] Example 3: Afforestation Test Tree Species: Huadong Nan

[0037] Selected 300 selected saplings with a ground diameter of 2-3cm and a tree height of 1.5-1.8m. The diameter is 7 times the ground diameter of the seedlings. The saplings are dug in a spherical shape and pruned. Among them, 30 plants are made of cloth with soil balls. Bandage; after the other 270 plants were taken out, the soil at the roots was washed away with a high-pressure water pump, 240 plants were soaked in the creek for 1.5-3 hours, and the remaining 30 plants were directly planted in the mountains. The specific treatment methods and results are shown in Table 3. The size of the planting hole is 40 × 40 × 30 cm. When planting, first fill the topsoil in the center of the hole to the shape of a steamed bun, insert the main root of the sapling into the topsoil of the steamed bun, and continue to backfill the soil to 20 cm. Push the soil into the gap of the tree root with a wooden stick, and press it. If...

Abstract

The invention provides a fleshy root sapling bare root afforestation method which is characterized by comprising the following steps: (1) nursery stock selection: selecting robust nursery stocks without plant diseases and insect pests in a nursery field according to tree species and specifications designed for afforestation, and marking the nursery stocks; compared with seedlings with soil balls and container seedlings, the bare-root afforestation method for the fleshy-root seedlings has the advantages that a bare-root seedling afforestation mode is adopted for the fleshy-root seedlings, on one hand, a plough layer of a nursery field can be protected, later crop cultivation cannot be affected, on the other hand, the carrying labor intensity of the seedlings is reduced, the problem of difficult labor is solved, and the economic benefit is increased. And 3, the transportation and shifting cost is reduced by 30-50%.

Description

technical field [0001] The invention relates to the technical field of bare-root afforestation of saplings, in particular to a method for bare-root afforestation of saplings with fleshy roots. Background technique [0002] In the barren mountains of key road sections in the south, in order to quickly achieve greening and ecological restoration, it is necessary to use saplings of 3-8 years old and 3-8cm in diameter for afforestation. Barren hillside afforestation sites usually lack irrigation conditions, and natural rainfall should be used to achieve watering goals. Therefore, in order to improve the survival rate of afforestation when using saplings with a diameter of more than 3 cm, it is usually required to use soil-bearing seedlings or container seedlings. These two methods have the following problems. One is that the soil ball will destroy the cultivated layer of the cultivated land, and the cost of container seedling cultivation is high; the second is that the weight o...
