Background
Camellia oleifera (Camellia oleifera Abel) belongs to the genus Camellia (Camellia) in the family Theaceae, is a high-quality woody edible oil plant peculiar to China, and belongs to evergreen small trees. The oil squeezed from the seeds of the camellia oleifera is called tea oil, is rich in various unsaturated fatty acids such as oleic acid, linoleic acid and the like, has the components of more than 90 percent, is high-quality woody edible oil, and has the effect of enhancing the immunity after being eaten for a long time.
The container seedling raising refers to a seedling raising mode for raising crops, fruit trees, flowers and forest seedlings by using a specific container. The container is filled with nutrient-rich culture soil and other matrixes, and the seedlings are usually cultured in protective facilities such as plastic greenhouses, greenhouses and the like, so that the seedlings can grow and develop under better nutrient and environmental conditions. The seedlings are planted along with rhizosphere soil mass, the root system is less damaged in the seedling lifting and planting process, the survival rate is high, the seedling reviving period is short, the emergence is fast, the growth is vigorous, and the method is particularly suitable for crops or trees which are not resistant to transplantation. At present, the camellia oleifera seedling raising technology is mainly container seedling raising, the seedling raising matrix is the basis of the container seedling raising technology, and the traditional seedling raising matrix is generally formed by adding biomass fertilizer or chemical fertilizer into inorganic substances and mixing.

Comparative example 1 is a commercially available substrate for growing seedlings of camellia oleifera.
Comparative example 2 differs from example 1 in that only woody peat is used.
Comparative example 3 differs from example 1 in that only herbaceous peat is used.
Comparative example 4 differs from example 1 in that no plant extract was added.
Comparative example 5 differs from example 1 in that no bacterial manure was added.
The physical and chemical properties of the seedling raising substrates of examples 1 to 4 and comparative examples 1 to 5 were measured in the same amounts, respectively, and the results are shown in the following tables.
TABLE 1 measurement results of physical and chemical properties of different seedling substrates
As can be seen from the data in Table 1, compared with the commercially available oil tea seedling substrate in the comparative example 1, the seedling substrate prepared by the method disclosed by the invention has the advantages that the contents of organic matters, total nitrogen, available phosphorus and quick-acting potassium are obviously improved, the pH is within the range of 5.5-6.0, the volume weight is reduced, the total porosity is obviously improved, and the oil tea seedling substrate is more suitable for the growth of oil tea. The seedling substrate prepared in example 3 in which the mass ratio of the woody peat to the herbaceous peat is 7:3 and example 4 in which the mass ratio of the woody peat to the herbaceous peat is 8:2 is superior in comprehensive physicochemical properties.
Comparative example 2 only used woody peat, which had a high organic content but also a high bulk density and a low total porosity; comparative example 3 only used herbaceous peat, which had a lower organic content but a higher total porosity and a slightly poorer water retention; comparative example 4 no plant extract was added, and the physicochemical properties of the seedling substrate prepared therefrom were not significantly different from those of example 1; comparative example 5, which did not include bacterial manure, did not further promote the release of fixed nutrients from the matrix, and therefore had lower organic matter, total nitrogen, available phosphorus, and available potassium content than in example 1.
The camellia oleifera seedlings were cultivated using the seedling raising substrates of examples 1 to 4 and comparative examples 1 to 5, respectively, and the storage rate, young shoot rate, seedling height, ground diameter, main root length, and occurrence of diseases and insect pests of each treatment were investigated, and the results are shown in the following table.
TABLE 2 determination of Camellia oleifera seedling growth status under different seedling raising substrate treatments
As can be seen from the data in Table 2, compared with a certain camellia oleifera seedling substrate sold in the market of the comparative example 1, the camellia oleifera seedling cultured by using the seedling substrate prepared by the method disclosed by the invention has higher preservation rate and young sprout treetop rate, and better botanical properties such as seedling height, ground diameter, main root length and the like, wherein the preservation rate is 95.45% on average, the young sprout treetop rate is 98.5% on average, the seedling height is improved by 22.95% on average, the ground diameter is increased by 23.96% on average, and the main root length is increased by 38.16% on average, which indicates that the seedling substrate disclosed by the invention can obviously promote the growth of the overground part and the underground part of the camellia. Comparative examples 2 to 5 also promoted the growth of camellia oleifera seedlings to some extent, compared to comparative example 1, but the effect was inferior to that of example 1.
Table 3 common pest and disease occurrence condition of camellia oleifera in seedling stage under different seedling raising substrate treatment
As can be seen from the data in Table 3, the incidence rates of diseases and insect pests of the camellia oleifera seedlings cultivated by the seedling substrate prepared by the method are low, wherein the average incidence rate of the camellia oleifera damping off is 0.26%, the average incidence rate of the camellia oleifera southern blight is 0.80%, the average incidence rate of the camellia oleifera moths is 1.13%, and the average incidence rate of the camellia oleifera loopers is 0.76%. Comparative examples 2 to 5 each had a certain effect of controlling the occurrence of pests, and comparative example 4, in which no plant extract was added, and comparative example 5, in which no bacterial manure was added, had relatively poor control effects.
