Description

Technical Field

[0001] The present invention relates to the technical field of daffodil cultivation, and in particular to a method and system for accurately controlling the flowering period of daffodils throughout the year based on environmental factor control. Background Art

[0002] Narcissus is a triennial herbaceous plant of the genus Narcissus in the Amaryllis family. It prefers a warm, humid environment, is relatively cold-resistant, and is best grown in sunny areas. It is often cultivated hydroponically or in soil.

[0003] Daffodils naturally bloom in winter and spring, making traditional cultivation methods inadequate for year-round viewing. Existing daffodil cultivation techniques suffer from issues such as crude bulb handling and limited environmental control, resulting in low flowering accuracy and uncontrollable cycles, making it difficult to meet year-round viewing needs. Summary of the Invention

[0004] To solve the problems in the background technology, the present invention is implemented through the following technical solutions: a method for accurately controlling the flowering period of daffodils throughout the year based on environmental factors, including the following specific methods:

[0005] Treatment before dormancy of daffodils: select daffodil bulbs and wrap them;

[0006] Storage of daffodils during dormancy: Store the wrapped daffodil bulbs in a frozen warehouse and ventilate them regularly;

[0007] Narcissus awakening treatment and cultivation: Take the dormant narcissus bulbs and transfer them to a sun glass room, cultivate them using culture medium, control the temperature, light intensity, and humidity of the sun room, and cultivate them for a set period.

[0008] Furthermore, the daffodil dormancy pre-treatment is specifically as follows:

[0009] Narcissus bulb selection: Choose mature narcissus bulbs that have been cultivated for three years, with a bulb diameter of ≥5cm and no pests, diseases or mechanical damage;

[0010] Packing process: Wrap the daffodil bulbs with exposed flower buds with paper and pack them in boxes, leaving ventilation holes in the boxes.

[0011] Furthermore, the storage of daffodils during dormancy period is specifically as follows:

[0012] Store the boxed daffodil bulbs in a freezer with the temperature controlled at 0-5℃, the air humidity at 60%-85%, and ventilate regularly.

[0013] Furthermore, the daffodil awakening is a conventional awakening, specifically:

[0014] From April of the Gregorian calendar, take out the daffodil bulbs from the frozen storage, transfer them to the sun room, and cultivate them using culture medium;

[0015] Environmental control: The temperature of the sunroom is 15-20℃, the illumination is 65%, the air humidity is ≥95%, and the cultivation period is 15 days.

[0016] Furthermore, in the environmental control, the temperature control is specifically as follows:

[0017] When the daytime temperature is ≥30℃, adjust the temperature to 15-18℃. When the daytime temperature is <30℃, adjust the temperature to 18-20℃.

[0018] Furthermore, the narcissus awakening is an early catalysis, specifically:

[0019] In July of the Gregorian calendar, bulbs are selected and stored in a constant temperature warehouse at a controlled temperature of 17-19°C to promote germination of daffodil bulbs.

[0020] In September of the Gregorian calendar, transfer the daffodil bulbs to a sunroom and cultivate them using a culture medium.

[0021] Environmental control: The temperature of the sun room is 12-16℃, the illumination is 65%, the humidity is ≥95%, the cultivation period is 45 days, and the starting time of the cultivation period is when the plants are transferred to the sun room.

[0022] Furthermore, the culture medium is: 70% river sand + 30% wood ash, wherein the particle size of the wood ash does not exceed 2 mm.

[0023] Furthermore, when the daffodils are cultivated after being awakened, the daily light exposure time is 8 hours.

[0024] The year-round precise flowering control system for daffodils based on environmental factors includes:

[0025] Environmental monitoring module, used to monitor the temperature, humidity and light intensity in the sun room;

[0026] The intelligent control module includes a temperature control submodule, a lighting submodule and a humidity submodule. The temperature control submodule is used to control the temperature in the sun glass room, the lighting submodule is used to control the illuminance in the sun glass room, and the humidity submodule is used to control the humidity in the sun glass room.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] This method and system for controlling the precise flowering period of daffodils throughout the year based on environmental factor control selects daffodil bulbs and puts them into dormancy. When the daffodils are needed to bloom at a specific period, the dormant daffodil bulbs are awakened. By integrating multi-dimensional environmental control such as temperature, light, and humidity, the flowering period of daffodils can be precisely controlled, thereby meeting the needs of different flowering periods of daffodils. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Figure 1 This is a flow chart of the method for accurately controlling the flowering period of daffodils throughout the year according to the present invention. DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] The embodiments of the method and system for controlling the precise flowering period of narcissus flowers throughout the year based on environmental factors are as follows:

[0032] Example 1:

[0033] See also Figure 1 The method of controlling the flowering period of daffodils throughout the year based on environmental factors includes the following specific methods:

[0034] Treatment before dormancy period of daffodils:

[0035] Choose mature daffodil bulbs that have been cultivated for three years. They should be firm, have full bulbs, be 5cm or larger in diameter, and be free of pests, diseases, and mechanical damage.

[0036] Narcissus bulb packaging process:

[0037] From the end of November to the beginning of December, when the flower buds just emerge from the bulbs, wrap the daffodil bulbs with paper and pack them in boxes. The boxes should have ventilation holes with a diameter of 2-3 cm. The loading capacity of each box should be ≤ 20 kg.

[0038] Storage of daffodils during dormancy:

[0039] Store the packed daffodil bulbs in a frozen warehouse with a temperature controlled at 0-5°C and an air humidity of 60%-85%. Use the daily movement of goods in and out of the frozen warehouse to achieve natural ventilation, which can ensure the circulation of fresh air and thus meet the oxygen needs of the plants. If it is a non-frozen warehouse, the whole box of daffodil bulbs must be moved out of the frozen warehouse every 10 days and ventilated for 30 minutes before being put back into the warehouse (regular ventilation). At this point, they can be stored for a long time, and the storage period is valid until November of the following year.

[0040] Narcissus awakening treatment and cultivation: Take the dormant narcissus bulbs and transfer them to a sun glass room, cultivate them using culture medium, control the temperature, light intensity, and humidity of the sun room, and cultivate them for a set period.

[0041] Narcissus awakening is a regular awakening (flowering needs from April to October), specifically:

[0042] From April of the Gregorian calendar (because daffodil bulbs before April can be cultivated and bloomed in a natural environment without technical intervention), take out the daffodil bulbs from the frozen storage and transfer them to a sun room. Use 70% river sand + 30% plant ash as the culture medium for cultivation. The plant ash needs to be sieved and the particle size is ≤2mm. The plant ash mainly kills bacteria and provides potassium, phosphorus, calcium and other trace elements.

[0043] Environmental control: The temperature of the sunroom is 15-20℃. When the temperature is ≥30℃ during the day, adjust the temperature to 15-18℃. When the temperature is <30℃ during the day, adjust the temperature to 18-20℃. The illumination is 65%, the daily illumination time is 8 hours, the air humidity is ≥95%, and the cultivation period is 15 days.

[0044] Example 2:

[0045] The difference between this embodiment and the first embodiment is that:

[0046] The awakening of daffodils is an early catalyst (flowering demand in November and December), specifically:

[0047] In July of the Gregorian calendar, high-quality daffodil bulbs are selected and stored in a constant temperature warehouse with a temperature control of 17-19°C. This is to keep the daffodil bulbs in a state of continued growth and development through temperature control, and promote germination of the daffodil bulbs;

[0048] In September of the Gregorian calendar, transfer the daffodil bulbs to a sun room and use 70% river sand + 30% wood ash as the culture medium for cultivation.

[0049] Environmental control: The temperature of the sun room is 12-16℃, the illumination is 65%, the daily illumination time is 8 hours, the humidity is ≥95%, the cultivation period is 45 days, and the starting time of the cultivation period is when the plants are transferred to the sun room.

[0050] The year-round precise flowering control system for daffodils based on environmental factors includes:

[0051] The environmental monitoring module includes a temperature sensor, a humidity sensor, and a light intensity sensor, which are used to monitor the temperature, humidity, and light intensity in the sun room. The accuracy of the temperature sensor is ±0.5°C, the accuracy of the humidity sensor is ±5%RH, and the accuracy of the light intensity sensor is ±100 lux.

[0052] The intelligent control module includes a temperature control submodule, a lighting submodule and a humidity submodule. The temperature control submodule is a heating and cooling air conditioner + soil heating tube, which is used to regulate the temperature in the sun glass room and automatically switches to a 15-20°C control mode according to the daytime temperature; the lighting submodule is a sunshade (shading rate 35%-65% adjustable) + LED fill light (power 0-100% adjustable), which is used to regulate the light intensity in the sun glass room and automatically match the 8-10 hours of lighting requirements; the humidity submodule is an ultrasonic humidifier + exhaust fan, which maintains the air humidity ≥95% (error ±5%) and is used to regulate the humidity in the sun glass room.

[0053] The narcissus year-round precise flowering control system also includes a central control module. The central control module is an intelligent controller based on the Internet of Things. It supports the automatic generation of a full-cycle control plan after the target flowering date is input, including the awakening method of the narcissus bulbs and the cultivation parameters after awakening, and links the execution of each sub-module. Users can monitor the data in real time through the terminal.

[0054] While the embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions, and alterations can be made to the embodiments without departing from the principles and spirit of the invention.
