Firstly, preparing a seedbed by a worker, wherein the seedbed is required to be limited in specification and size, so that the growth of the eucalyptus seedlings at the later stage is facilitated, and the seedbed is of the following size: the width of the bed bottom is 1.3m, the length is less than 5m, the width of the pavement is 5cm, three seedbeds can be prepared because three different seedlings are needed, then the beds are ridged, weeds on the surface of the beds and soil on the surface are shoveled, the seedbeds are subjected to insecticidal treatment by using insecticide, the insecticide is trichlorfon, the insecticide can enter the digestive system of the trichlorfon through an insect inlet to play a role in poisoning, and the proportion of the insecticide to water is 1:25, uniformly mixing water and insecticide, spraying in a spraying mode, preparing a seedling raising matrix, paving a layer of yellow soil core soil and coconut husk on a seedling bed sprayed with the insecticide, wherein the ratio of the yellow soil core soil to the coconut husk is 1:1, paving the yellow soil core soil, paving the coconut husk, and the thickness of the yellow soil core soil and the coconut husk is 4-7cm, wherein the coconut husk can increase the air permeability of the seedling raising matrix, facilitate the production of the seedlings of the eucalyptus oil at the later stage, flattening the seedling bed, carrying out sun screening and ventilation on the sterilized and insecticidal seedling bed for 1-2 days, then carrying out strickling on the bed surface, uniformly paving a layer of fire-burned soil on the seedling bed after strickling, strickling again, and compacting by using a wood board;
preparing seedlings, namely selecting seed seedlings, breeding seedlings cultivated by fruits of eucalyptus, adding pesticides such as carbendazim and the like into the seed seedlings for seed dressing and disinfection when the seed seedlings are adopted for breeding, adding sieved clean fire-burned soil or coconut husk, uniformly stirring and sowing, uniformly covering the seeds after sowing by the fire-burned soil or the coconut husk, spraying water on the sowed seed seedlings, finally covering a film, wherein the film vault is 35-45cm away from a seedbed so as to be convenient for ventilation and ventilation, detecting the growth environment of the seedlings by adopting a temperature and humidity monitor during the growth of the seedlings, opening films at two ends if the temperature is higher so as to ensure ventilation, controlling the growth temperature of the seedlings to be 25-35 ℃ and the relative humidity to be 85-95%, if the humidity is insufficient, watering can be carried out, a spraying mode is adopted for watering, if the illumination is strong, a layer of sunshade net can be covered for protecting seedlings, then seedling management can be carried out, the seedling management can be divided into small seedling management and large seedling management, in the small seedling management, urea diluted for 1-2 times can be sprayed to avoid tender leaves being burnt by fertilizers, in the large seedling management, watering is carried out regularly, the watering interval is 3-5d, and fertilizer is required to be applied weekly, the concentration of the fertilizers is 2% -5% of urea, classification can occur along with the growth of seedlings, at this time, staff can carry out classification treatment according to the growth condition of the seedlings so as to better manage and transplant the later stage, and then the classified seedlings are transplanted into corresponding environments;
therefore, the staff can adopt different seedlings to carry out breeding on the same substrate, and lighting time, temperature and humidity and fertilizing amount are controlled in the same range, so that seedling raising time can be effectively shortened, different seedling breeding time is compared, and effective reference is provided for the later eucalyptus citriodora planting.
Although the present invention has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present invention.
