Problems solved by technology

[0003] The preservation and breeding of germplasm resources is an important part of vegetable breeding. The existing preservation and breeding methods are mainly field preservation and breeding and southern breeding. However, both methods are greatly affected by climate, labor-intensive, high cost and poor confidentiality. and other issues, and the number of additional generations of breeding in conventional methods is 2 to 3 generations per year

Embodiment 1

[0034] In this example, ox horn pepper is cultivated in nutrient solution under the conditions of artificial light plant factory. The seeds of ox horn pepper are soaked in warm water at 52°C for 8 minutes, and then placed in the dark condition of 24°C for accelerated germination to obtain germinated seeds. The LED light quality ratio is White: red: blue = 3:2:1, the color temperature of white light is 4500K, the wavelength of red light is 670nm, the wavelength of blue light is 460nm, and the light intensity is 320μmol·m -2 ·s -1 As a light source, the light source is provided by LEDs. The light time is 12 hours, the temperature is controlled at 25°C, and the air humidity is 70%, and the germinated seeds are treated. The nutrient solution formula is: 56.0mg / L N, 22.8mg / L P, 184.7mg / L K, 80.0mg / LCa, 24.0mg / L Mg, 64.0mg / L S, 5.6mg / L Fe, 0.5mg / L B, 0.5mg / L L Mn, 0.05mg / L Zn, 0.02mg / L Cu, 0.01mg / L Mo. During the growth period of ox horn pepper, the consumed nutrient solution was...

Embodiment 2

[0036] In this example, under the condition of artificial light plant factory, the nutrient solution is used to cultivate Chaotian pepper. The seeds of Chaotian pepper are soaked in warm water at 55°C for 12 minutes, and then placed in a dark condition of 28°C for accelerated germination to obtain germinated seeds. The LED light quality ratio is White: red: blue = 4:3:2, the color temperature of white light is 5000K, the wavelength of red light is 660nm, the wavelength of blue light is 465nm, and the light intensity is 340μmol·m -2 ·s -1 As a light source, the light source is provided by LEDs. The light time is 15 hours, the temperature is controlled at 28°C, and the air humidity is 65%, and the germinated seeds are treated. The nutrient solution formula is: 52.0mg / L N, 21.0mg / L P, 189.0mg / L K, 65.0mg / LCa, 29.0mg / L Mg, 62.0mg / L S, 3.2mg / L Fe, 0.8mg / L B, 0.2mg / L L Mn, 0.07mg / L Zn, 0.03mg / L Cu, 0.02mg / L Mo. During the growth period of Chaotian pepper, the consumed nutrient so...

Abstract

The invention relates to the technical field of plant breeding methods, and provides a method for accelerating pepper germplasm breeding generation adding in a plant factory. The method comprises the following steps: germinated pepper seeds are transferred to an LED artificial light plant factory condition for nutrient solution cultivation; light source conditions of the artificial light plant factory are as follows: the LED mass-luminosity ratio of white to red to blue is (1-5):(1-4):(1-3), the light intensity is 300-360 [mu]mol.m<-2>.S<-1>, and the illumination time is 10-15 h / d; the color temperature of the white light is 4000-6000 K, the wavelength of the red light is 640-680 nm, and the wavelength of the blue light is 455-470 nm. The breeding method provided by the invention gets rid of the constraint of natural conditions and the limitation of regionality, can control the growth cycle of the plants and promote the rapid development of the plants, and with adoption of a completely closed cultivation environment, a good growth environment for the breeding of germplasm resources is created.

Description

technical field [0001] The invention relates to the technical field of plant breeding methods, in particular to a method for accelerating germplasm breeding and adding of capsicum in a plant factory. Background technique [0002] Capsicum (Capsicum annuum L.) is a cross-pollinated crop with a natural hybridization rate of about 10%, strong heterosis, and high yield, good quality, and strong stress resistance. Pepper is an important vegetable and condiment, the seed oil is edible, and the fruit also has the medicinal effect of repelling insects and sweating. It also has pharmacological functions, such as antibacterial and insecticidal, improving the digestive system, and promoting local blood circulation. [0003] The preservation and breeding of germplasm resources is an important part of vegetable breeding. The existing preservation and breeding methods are mainly field preservation and breeding and southern breeding. However, both methods are greatly affected by climate, ...
