Description
Technical Field
The invention relates to the technical field of forestry seed cultivation, in particular to a special seedling raising device and a special seedling raising method for tree seeds in a forest zone.
Background
Seeding and seedling raising are common technology in large-scale forest planting activities at present, and the root systems of forestry seedlings are stronger through the cultivation of a seedling raising stage, so that the capability of adapting to field environments is stronger, and the survival rate of the seedlings can be improved. In the process of seedling cultivation, the humidity of the soil has great influence on seedling cultivation quality, and the proper humidity of the soil is one of key factors for successful seedling cultivation of the tree seeds.
At present, the watering mode is mainly used for watering soil periodically by people, because the seedling raising barrel or the seedling raising tray is smaller, the accumulation of water is limited, the situation of too much or too little water is easily caused by the artificial watering, the air gap of the soil capillary is filled with water due to the too much water, the oxygen supply in the soil is insufficient, the root system of the seedling is choked to die, the root system development is inhibited when the water quantity is too small, and the growth of the seedling is slow.
With the continuous development of the seedling raising technology, researchers have proposed a way of replacing manual watering by using an automatic watering system, taking patent CN202022024709.9 as an example, which uses a sensor to monitor soil humidity and plant water demand, so as to avoid the problems of excessive watering or insufficient watering possibly existing in the traditional manual watering. In addition, some techniques utilizing capillary principle also bring new possibility for water regulation in tree seed seedling, take patent CN201821356852.4 as an example, its non-woven cotton core installed in seedling substrate is connected to the liquid storage tank through the aperture, utilize capillary principle, when the seed needs water, can automatically absorb water through non-woven cotton core, save artifical daily supply.
However, while the introduction of these forms of regulation brings numerous advantages to the regulation of moisture in the raising of tree species, there are also problems and disadvantages. Firstly, the automatic watering system needs to regularly maintain and replace components such as a sensor, has higher cost, also needs certain professional knowledge and skill for the maintenance and management of technical equipment, and has higher requirements on the professional quality of operators. Secondly, by utilizing the mode of cotton core water absorption, moisture can enter the seedling raising matrix contacted with the cotton core firstly, taking the patent CN201821356852.4 as an example, the moisture in the cotton core is transmitted from bottom to top, the moisture can be firstly transmitted to the seedling raising matrix at the bottom and then is transmitted upwards, and the moisture is more inclined to spread downwards under the action of gravitational potential energy, so that a moisture gradient is formed between the seedling raising matrix at the bottom and the seedling raising matrix at the upper part, the humidity in the seedling raising box is uneven, when the moisture gradient exists in the seedling raising matrix, the root system of seedlings is easy to cause excessive growth to the bottom, the root system of seedlings is relatively poor in growth, the root system of seedlings is unbalanced, a series of problems of insufficient grip of seedlings to soil palm, poor wind resistance and fall resistance and the like can be caused for the seedlings in a forest region needing to transplant the field, and the field transplanting of tree species is unfavorable. Although forestry workers can prune the root system of the seedling before transplanting to promote the root system to develop more evenly and healthily, the growth vigor of the seedling sapling influences the growth of the seedling and the ability of adapting to new environment, and open wounds or cuts are brought to the seedling, so that the risk of seedling infection diseases is increased, and challenges are brought to management and nursing of the forestry workers.
Disclosure of Invention
The invention aims to solve the problems of the current seedling raising device based on the cotton core water absorption mode: the humidity in the seedling box is uneven, and the moisture gradient in the seedling matrix causes that the seedling root system is easy to excessively grow downwards, so that the seedling root system is unbalanced in development, and the seedling root system has insufficient grip strength to soil, poor wind resistance and fall resistance and reduced stress resistance after being transplanted outdoors.
