Step S5: centralized cultivation: after the camellia oleifera plants are cultivated to a certain degree, transplanting the camellia oleifera plants into camellia oleifera woodland for cultivation.
Step S6: fertilization and cold resistance: decomposed organic fertilizers and compound fertilizers, particularly cake fertilizers and chemical fertilizers, are applied to the tea-oil tree inter-row spaces, and the fertilizing treatment can improve the soil temperature, protect the roots and promote the growth of the roots.
More specifically: through key technical measures such as applying organic fertilizer and compound fertilizer, the physicochemical properties of soil can be improved by applying the organic fertilizer, so that the growth condition of the oil tea is well improved, indexes such as the land diameter, the spring tip weight, the fresh fruit weight per mu yield of the oil tea and the like are superior to those of contrast treatment, and from the point of the indexes such as the leaf sponge tissue thickness, the relative water content, the relative conductivity and the like which can reflect the cold resistance of the oil tea, the oil tea treated by applying the organic fertilizer is most cold-resistant, and the compound fertilizer treatment is secondly applied.
Step S7: ridging and antifreezing: the method is characterized in that the earth is earthed around the roots or among rows of the camellia oleifera, the earth thickness is 5cm, 15 cm and 25cm, the earth area is 1 square meter, the earth is earthed up and prevented from freezing, direct attack of wind and frost can be resisted, ground radiation at night can be prevented, the ground temperature rise of the camellia oleifera forest is promoted, and the cold resistance of the tree body is improved.
More specifically: the soil ridging of 25cm can obviously improve the soil water content and the soil temperature of the camellia oleifera woodland, reduce the soil volume weight and facilitate the camellia oleifera to better adapt to natural low temperature. When the camellia oleifera forest with the thickness of 15-25cm is earthed up and encounters natural low temperature, the camellia oleifera forest can better reduce the water content through regulation, improve the concentration of in vivo cell sap, reduce the possibility of cell icing, and has small damage degree of camellia oleifera cell membranes and less electrolyte extravasation, thereby improving the cold resistance of the camellia oleifera forest.
Step S8: trimming: pruning is carried out on the camellia oleifera trees, so that the trees are moderately dwarfed, the included angle between the main branches and the trunk is larger, the ventilation and light transmission in the crowns and the up-down penetrability are stronger (namely, more snow flakes can penetrate the crowns to land on the ground), the lignification degree of the young shoots is enhanced, the accumulation amount of the snow flakes on the crowns is reduced, and the stress resistance is enhanced.
More specifically: through key technical measures such as dwarfing the height of the oil-tea camellia tree body, evacuating the internal chamber and the like, the growth condition of the oil-tea camellia is well improved, indexes such as the height of the tree, the crown width, the land diameter, the length of spring tips, the fresh fruit weight per mu yield of the oil-tea camellia and the like are superior to those of contrast treatment, and the evacuating internal chamber is most cold-resistant to the oil-tea camellia from the indexes such as leaf sponge tissue thickness, relative water content, relative conductivity and the like which can reflect the cold resistance of the oil-tea camellia. .
In conclusion, in the cultivation method for improving the cold resistance of the camellia oleifera, the thickness of the sponge tissue of the leaf, the relative water content and the relative conductivity are key index factors influencing the cold resistance of the camellia oleifera, and are negatively related to the cold resistance. By applying organic fertilizer, ridging for 15-25cm, evacuating internal space of the camellia oleifera and other key cultivation technical measures, the physical and chemical properties of the soil can be improved, the light transmittance of the camellia oleifera can be increased, the growth conditions of the camellia oleifera can be well improved, the yield is obviously improved, and the cold resistance is obviously enhanced. Therefore, in the subsequent tea-oil tree forestation process, a plurality of organic fertilizers are applied, the rhizosphere is earthed up by 15-25cm, and the tea-oil tree body is subjected to a composite cultivation measure of evacuating the interior, so that the yield of the tea-oil trees can be improved and the stress resistance of the tea-oil trees can be enhanced.

Secondly, the method comprises the following steps: the sponge sleeve 1 is sleeved on the plant surface, so that each area on the surface of the plant can be uniformly soaked, the anti-freezing effect is good, the mode is different from the existing mode of injecting anti-freezing solution into the plant, the mode is poor in safety, the anti-freezing solution injected into the plant can cause certain damage to a human body due to certain toxicity of the anti-freezing solution, the safety is poor, and the mode has good safety and good anti-freezing effect.
Thirdly, the method comprises the following steps: under special or severe conditions, when the temperature detector 36 detects that the temperature of the plant is too low, if the plant is not subjected to rapid anti-freezing treatment at this time, the situation that the plant is frozen and frozen is very easy to occur, the signal is transmitted to the controller through the temperature detector 36, and then the controller controls the motor II 14 to operate, so that the first state of the method is switched to the second state, the liquid spraying component is in a mode of reciprocating and vertically moving while swinging, so that the liquid spraying component is in reciprocating and vertically moving while reciprocating and rotating, the contact area between the sprayed anti-freezing liquid and the sponge sleeve 1 is increased, the speed of the anti-freezing liquid absorbed by the sponge sleeve 1 is faster, and during fixed spraying, more time is probably needed for the sponge sleeve 1 to uniformly absorb the anti-freezing liquid, but under the swinging spraying of the method, the absorption speed of the sponge sleeve 1 is increased, and further the surface of the sponge sleeve is rapidly wetted, therefore, the plant is well protected, and meanwhile, the anti-freezing liquid is uniformly sprayed, so that when the anti-freezing liquid is transmitted to the plant through the sponge sleeve 1, the spraying uniformity can be embodied, and the anti-freezing uniformity is improved.
Fourthly: according to the mode, automatic temperature detection is carried out in a mode of the temperature detector 36, the mode is different from a mode of manually spraying anti-freezing solution, the situations that the anti-freezing solution cannot be sprayed in time, the spraying is excessive and the spraying is too low can occur, the mode can adaptively drive the liquid spraying assembly to spray the anti-freezing solution through the temperature change detected by the temperature detector 36, the spraying range is adjustable, and then plants can be in faster contact with the anti-freezing solution, so that the effect of efficient protection is achieved, and the high automation and integration effects are achieved.

Secondly, the method comprises the following steps: because the antifreeze is prepared by mixing ethylene glycol and distilled water according to a ratio, in the actual use process, the antifreeze can be evaporated under the condition of temperature change, and further loss of the antifreeze is caused.
Thirdly, the method comprises the following steps: when the anti-freezing liquid is sprayed on the sponge sleeve 1, the anti-freezing liquid is injected into the liquid outlet ring 11 through the communication port 28 and the water inlet 13, which is a fixed spraying state, but when the anti-freezing liquid is switched to a swing spraying state, the liquid outlet ring 11 rotates in a reciprocating manner, so that the water inlet 13 is intermittently aligned with the communication port 28, the anti-freezing liquid flows into the liquid outlet ring 11 when the anti-freezing liquid is aligned with the liquid outlet ring 11, the liquid outlet ring 27 is not communicated with the liquid outlet ring 11 when the anti-freezing liquid is not aligned with the liquid outlet ring, at the moment, the water entering the liquid outlet ring 27 can be quickly filled in the liquid outlet ring 27, so that the anti-freezing liquid can be uniformly conveyed towards the liquid outlet ring 11 at different angles and directions when the liquid outlet ring 27 is aligned with the liquid outlet ring 11 next time, and the uniform degree of the anti-freezing liquid in multiple directions can be kept consistent when the anti-freezing liquid is sprayed on the sponge sleeve 1, and the spraying uniformity degree is improved.
Fourthly: when the water outlet ring 27 is not communicated with the liquid outlet ring 11 and the antifreeze in the water outlet ring 27 is filled, but at the same time, the piston mechanism is still pressing water in continuous operation, so that the return spring one 20 of the piston head 19 shown in fig. 6 does not deform during normal piston operation and transportation, but after the antifreeze in the water outlet ring 27 is filled, the piston head 19 cannot move upwards any more, the return spring one 20 is squeezed, but the piston rod 22 drives the connecting block 18 to operate continuously, so that the distance from the connecting block 18 to the piston head 19 changes, and the return spring one 20 forms elastic potential energy, when the water outlet ring 27 is communicated with the liquid outlet ring 11, the return spring one 20 releases the elastic potential energy immediately, so that the piston head 19 is reset quickly, the antifreeze in the water outlet ring 27 is transported into the liquid outlet ring 11 by further pressurization, and the pressurized antifreeze is sprayed out more quickly and further, when avoiding spraying pressure not enough, probably appearing not spraying sponge cover 1 and spraying the condition on the 2 inner walls of shell, this mode is when adapting to out the swing of liquid ring 11, can also give out liquid ring 11 and carry out the transport antifreeze that lasts, simultaneously at the in-process of carrying, still can give antifreeze with pressure, and then makes out liquid speed faster, and the hydrojet distance extension, therefore this mode has the better effect of practicality.
