Description

Technical Field

[0001] The present invention belongs to the technical field of rose cultivation in facilities, and in particular relates to a rose intelligent breeding accelerator and a method for improving rose breeding efficiency. Background Art

[0002] Cut roses occupy a pivotal position in the global flower market. Their beautiful flowers, rich colors and long flowering period are deeply loved by consumers. With the rapid development of the flower market, consumers are increasingly pursuing novel varieties, and expect to see more rose varieties with unique colors, such as blue; novel flower shapes, such as double petals, single petals, and other forms and different fragrances.

[0003] However, traditional cut rose breeding faces many challenges. On the one hand, the constant changes in light and temperature in the natural environment and the cultivation environment, such as changes in light duration and light intensity caused by the alternation of seasons, large changes in temperature in extreme weather, and the lack of precision and systematicity in nutrient supply during the growth process, lead to low fertilizer utilization, slow plant growth, and difficulty in accurately controlling the growth cycle. These problems greatly limit the breeding efficiency. On the other hand, the traditional breeding cycle is long, and only 1-2 breeding operations can be carried out each year. It generally takes 4-6 years or even longer from hybrid pollination to obtain new varieties with stable genetics, which is far from meeting the market's demand for rapid renewal of novel cut rose varieties. Therefore, it is of great practical significance to develop a cut rose breeding accelerator that can overcome the above problems and a method to improve rose breeding efficiency.

[0048] The technical solutions provided by the present invention are described in detail below in conjunction with the embodiments, but they should not be construed as limiting the protection scope of the present invention.

[0049] The present invention is implemented in a cut rose greenhouse of the International Flower Technology Innovation Center in Chenggong District, Kunming City, Yunnan Province, and the varieties of the cut roses are 'Norma Jenny', 'Wushuang', and 'Borabora'.

[0050] Example 1

[0051] A cut rose intelligent breeding accelerator is built in the greenhouse to cultivate cut roses. The workflow diagram of the cut rose intelligent breeding accelerator is as follows: Figure 1 shown.

[0052] Cut rose varieties: 'Norma Jeanne';

[0053] The specific breeding methods are as follows:

[0054] (1) Intelligent light control system

[0055] The greenhouse is equipped with LED light source arrays and sunshade nets to provide lighting conditions with adjustable light intensity and light cycle, and to accurately adjust the light intensity, light duration and spectral distribution according to the different growth and development stages of cut roses.

[0056] During the seedling stage, a higher proportion of blue light is provided, with a red-to-blue light ratio of 2-2.5:1, a lighting duration of 12-14 hours / day, and a light intensity of 20,000-30,000 lux to promote leaf photosynthesis and chlorophyll synthesis, so that the seedlings grow strong; during the vegetative growth period, the red-to-blue light ratio is 3-4:1, the light intensity is increased to 40,000-60,000 lux, and the lighting duration is 14-16 hours / day to promote leaf photosynthesis and accumulation of photosynthetic products, laying a good material foundation for subsequent flowering; entering the flowering period, the red-to-blue light ratio is 3-4:1, the light intensity is adjusted to 40,000-50,000 lux, providing full-spectrum balanced lighting, with a lighting duration of 10-12 hours / day to ensure that the flowers are bright in color and full in shape.

[0057] When the light sensor detects that the light intensity is too strong and exceeds the preset range value of each growth and development stage, the shading device can automatically adjust the shading degree to the preset range value of each growth and development stage according to the light intensity to prevent the plants from being damaged by excessive light. When the light intensity on a cloudy day is less than the preset range value of each growth and development stage, the light intensity can be adjusted to the preset range value of each growth and development stage.

[0058] (2) Precision temperature and humidity control system

[0059] By using high-precision temperature sensors and intelligent heating and cooling equipment (such as boilers, air-energy heat pumps, hot air blowers, air conditioners, fans, wet curtains, etc.), the temperature in the breeding greenhouse is accurately controlled within the range of 15-28°C, and fine-tuned according to different growth stages.

[0060] Seedling stage: The daytime temperature is stable at 18-22℃, and the night temperature is stable at 16-18℃, which is conducive to the growth of stems and leaves and the development of the root system of the seedlings, and promotes the healthy growth of the seedlings;

[0061] Vegetative growth period: The daytime temperature is stabilized at 20-25℃, and the nighttime temperature is stabilized at 18-20℃, simulating the natural temperature difference between day and night, promoting the normal photosynthesis and respiration of the plants, and improving the accumulation and utilization efficiency of nutrients;

[0062] Flowering period: The daytime temperature is stable at 20-22℃, and the night temperature is stable at 15-18℃, which is conducive to the opening of flowers and prolongs the opening time and shelf life of flowers.

[0063] When the temperature sensor detects that the temperature exceeds the set upper limit, the data analysis and decision-making software will immediately issue a command to start the ventilation equipment (fan) or shading system in the intelligent refrigeration equipment to lower the temperature;

[0064] Use humidity sensors and humidification / dehumidification equipment (such as ultrasonic humidifiers, high-pressure spray humidifiers, fans, wet curtains, etc.) to accurately maintain air humidity between 50-70%. The humidity sensor monitors humidity changes in real time. When the humidity is higher than the set value, the ventilation equipment is automatically turned on to discharge excess moisture. When the humidity is lower than the set value, the humidification equipment is automatically started to increase the humidity and maintain humidity balance.

[0065] During the seedling stage, maintain a high humidity of 60-70% to ensure rapid growth of seedlings;

[0066] During the vegetative growth period, humidity should be controlled between 50-60% to promote growth; at this stage, the plants grow vigorously and require a large amount of water, but care should also be taken to prevent excessive humidity from causing disease growth. When the air humidity is higher than 60%, use ventilation equipment to increase ventilation and reduce humidity;

[0067] During the flowering period, gradually reduce the humidity to 55-65% to allow the flowers to bloom well and reduce the risk of disease. At this stage, the humidity should not be too high, and be careful to prevent water droplets from staying on the petals for a long time and causing diseases. At the same time, strengthen ventilation to prevent excessive humidity from causing diseases such as gray mold and ensure the ornamental quality of the flowers.

[0068] (3) Gas composition control system

[0069] The carbon dioxide concentration is controlled between 600-800ppm by using the carbon dioxide supply system (gaseous carbon dioxide supply system) and monitoring device, which meets the demand of cut roses for photosynthesis substrate carbon dioxide at different growth stages, ensures sufficient supply of raw materials for photosynthesis reaction, and promotes vigorous growth of plants.

[0070] Seedling stage: rapid growth stage, photosynthetic capacity continues to increase, the carbon dioxide concentration is maintained between 600-700ppm during the seedling stage to promote rapid growth of seedlings.

[0071] Vegetative growth period: Due to the vigorous photosynthesis, the carbon dioxide concentration is maintained between 700-800ppm during the vegetative growth period, which can promote the synthesis and accumulation of photosynthetic products and promote growth

[0072] Flowering period: Due to vigorous photosynthesis, maintaining the carbon dioxide concentration between 700-800ppm during the flowering period can prolong the flowering period.

[0073] (4) Integrated water and fertilizer precision nutrition supply system

[0074] The supply of nutrient solution is carried out by using a water-fertilizer integrated circulation irrigation system, which monitors the substrate moisture, EC value and nutrient composition data analysis results to irrigate the nutrient solution, ensuring a uniform supply of nutrient elements and avoiding nutrient solution waste and salt accumulation.

[0075] (a) Fertilizer storage and preparation

[0076] Two fertilizer storage tanks (A fertilizer storage tank and B fertilizer storage tank) are set up. The storage tanks are used to store fertilizer mother liquor A and fertilizer mother liquor B respectively. Each tank has moisture-proof, anti-caking and precise metering devices. Each cubic meter of fertilizer mother liquor A contains 10kg of calcium nitrate, 5kg of potassium nitrate, and 20kg of chelated iron; each cubic meter of fertilizer mother liquor B contains 35kg of potassium nitrate, 6kg of ammonium sulfate, 25kg of magnesium sulfate, 25kg of magnesium nitrate, 6kg of potassium sulfate, 24kg of potassium dihydrogen phosphate, 2kg of manganese sulfate, 450g of borax, 150g of zinc sulfate, 120g of copper sulfate, and 350g of sodium molybdate. The solvent of the fertilizer mother liquor is water. Dissolve the fertilizer components required for the above mother liquor configuration into the A and B fertilizer storage tanks respectively to make fertilizer mother liquor A and fertilizer mother liquor B. The precise metering device and valve installed in the fertilizer storage tank can accurately control the flow of fertilizer mother liquid A and fertilizer mother liquid B to ensure that fertilizer mother liquid A and fertilizer mother liquid B are accurately allocated to the water-fertilizer mixing tank according to the required volume ratio.

[0077] (b) Water and fertilizer mixing and transportation

[0078] A water-fertilizer mixing tank is used to stir and mix fertilizer mother solution A and fertilizer mother solution B to obtain a mixture of fertilizer mother solution A and fertilizer mother solution B, wherein the volume ratio of the fertilizer mother solution A to the fertilizer mother solution B is 1:1. The EC value of the nutrient solution is adjusted according to the requirements of the different growth stages of cut roses: seedling stage, vegetative growth stage, and flowering stage. Using the efficient stirring device in the mixing tank, the fertilizer mother solution A and fertilizer mother solution B that are accurately measured according to the EC value requirements of the different growth and development stages of the rose are fully mixed with water to obtain a nutrient solution; when the fertilizer mother solution A and the fertilizer mother solution B are fully mixed with water for fertilization, it is carried out according to the EC value requirements of the different growth and development stages of the rose.

[0079] The reference EC values ​​of cut roses at different growth stages are as follows:

[0080] The EC value of the nutrient solution during the seedling stage is controlled at 1.0-1.3mS / cm;

[0081] During the vegetative growth period, the EC value of the nutrient solution is controlled at 1.4-1.6mS / cm;

[0082] During the flowering period, the EC value of the nutrient solution is controlled at 1.6-1.8mS / cm.

[0083] The pH of the nutrient solution is generally controlled between 5.0-6.0, with 5.5 being optimal.

[0084] The delivery system consists of corrosion-resistant pipes and intelligent water pumps. According to the real-time water and fertilizer needs of the plants, the intelligent water pump adjusts the delivery pressure and flow rate, and accurately delivers the nutrient solution to the root of each cut rose through the drip irrigation pipe.
