Bare root afforestation method for fleshy root saplings

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...

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.
