Firstly, placing a cuttage box body into a liquid storage container, and placing the cuttage box body through an outer edge, wherein a height difference exists between the bottom of the cuttage box body and the inner bottom surface of the liquid storage container, then, pouring broad-spectrum bactericide into each cuttage grid chamber, performing primary sterilization treatment on a cuttage matrix, and preventing a trunk incision from being infected by bacteria or fungi by the bactericide remained in the cuttage matrix, so that the infection and rot risk of pathogenic matters of the incision is reduced; the residual broad-spectrum disinfectant solution enters a liquid storage container and is then poured out. Then, the grassiness cutting is inserted into each cutting cell, cutting liquid is poured after the grassiness cutting cell is inserted for the first time, the liquid level is observed after the cutting liquid enters the liquid storage container, so that the liquid level in the liquid storage container is higher than the bottom surface in the cutting cell, namely, the liquid level is required to be higher than the bottom surface in the cutting cell, the cutting matrix at the bottom is ensured to be immersed in the cutting liquid, then the grassiness batch cutting device can be placed at a ventilation and light scattering position, the liquid level in the liquid storage container is always higher than the bottom surface in the cutting cell, and the cutting liquid can always wet the cutting matrix above and directly contacted with the cutting notch through the wetting effect.
In addition, the inventor finds that in the process of research, some of the elephant grass cuttings which fail cutting are actually successfully rooted, but the root systems of the elephant grass cuttings directly wither without extending downwards, which has great relation with the too extensive management mode of the traditional cutting technology. In order to overcome the problem, the scheme eliminates rotten or blackened or withered cuttings after 25-35 days, and the liquid in the liquid storage container is poured out to replace the liquid into the plant nutrient solution. After 25-35 days, under the temperature suitable for grassiness cuttage, normally healed tissues are generated and rooted in a small amount, at the moment, a small number of cuttings which can be certainly failed in cuttage are removed, rot, blacken and withered are visible by naked eyes, then the height of a cuttage box body is raised until the height of the bottom surface inside a cuttage compartment is higher than the height of the liquid level inside a liquid storage container, at the moment, the cuttage matrix inside the cuttage compartment is not directly contacted with plant nutrient solution, the temporary planting environment is simulated through the high humidity below, and further the capillary root system which is grown is induced to be quickly pricked into the depth of the cuttage matrix. And then, continuing maintenance, in the maintenance process, periodically reducing the height of the cutting box body, enabling the bottom surface inside the cutting chamber to be in contact with plant nutrient solution in the liquid storage container for a specified period of time, further enabling the cutting matrix to realize dry-wet circulation, being more beneficial to rapid root induction growth and reducing the blackening risk of the cut.
Wherein, the 'regular' in the height of the cutting box body is reduced regularly, and the cutting matrix on the surface layer is preferable to start dehydration according to specific conditions such as local temperature, air humidity and the like; the "specified duration" depends on the water absorption of the specific cutting medium, and the cutting medium that can be surface layer is infiltrated as a reference standard.
Those skilled in the art will appreciate that: the 'thoroughly watering' in the method means that all cutting matrixes in the cutting grid fully absorb water; the term "ventilation diffusion" in the present method means an area having good ventilation performance and no direct sunlight but scattered light.
In addition, the cutting matrix, broad-spectrum bactericide, cutting fluid, plant nutrient solution and the like in the method can all use the prior art.
Further, step S1 further includes: plugging a first air hole on the side wall of the liquid storage container, so that cutting liquid can rise to a higher height in the early stage of cutting of the elephant grass, and the cutting liquid is ensured to be immersed into the bottom surface of the interior of the cutting grid chamber;
further, step S5 further includes: the liquid level in the liquid storage container is lower than the first air holes, and the blocking of the first air holes is removed, so that the first air holes on two opposite sides can form convection, and the ventilation performance of the cuttage matrix is improved.
Further, step S6 further includes: the second air holes and the air flow channels on the side wall of the cuttage box body are all lifted to be above the liquid storage container, so that ventilation and air permeability of cuttage substrates are improved, fungus propagation rate is reduced, probability of rot of callus and blackening of incisions is reduced, and the cuttage survival rate of grassiness is improved.
Compared with the prior art, the invention has the following advantages and beneficial effects:
1. according to the device and the method for batch cutting of the grasses, the integral height of the cutting box body can be adjusted through the height adjusting component at different stages of cutting propagation of the grasses, so that the height of each cutting cell immersed below the liquid level in the liquid storage container is adjusted in batches, the liquid content and the liquid type of the matrix are flexibly adjusted at different stages of cutting growth of the grasses, and further the rapid acceleration of callus at the cut of the grasses stalks, the induction of rooting of cuttings and the rapid growth of root systems are facilitated until the condition of transferring the roots to the ground is met.
2. According to the grassiness batch cutting device and the grassiness batch cutting method, the whole height of the cutting box body can be flexibly adjusted through the gaskets with different numbers and thicknesses, so that the height of the cutting cells can be adjusted, the long-term stability is kept after the cutting cells are adjusted in place, and a lifting device driven by electric power or hydraulic power is not needed, so that the grassiness batch cutting device is beneficial to keeping low-cost production and maintenance, and is particularly suitable for popularization of farmers and pastures for planting grassiness on a small scale.
3. The device and the method for mass cutting of the grasses can obviously improve the ventilation performance of the cutting matrix, reduce the propagation rate of fungi, reduce the probability of rot of callus and blacking cut, and improve the cutting survival rate of the grasses.
4.
