Problems solved by technology

More and more advanced technologies and equipment have been widely used in plant science laboratories, greatly improving research efficiency, but the growth cycle of crops has gradually become one of the most important limiting factors restricting the progress of scientific research
[0003] Traditional breeding often requires multiple generations of creation and selection of variations and stable offspring to obtain excellent varieties, which will take a long time

Embodiment 1

[0026] In this example, Zhongshuang 11 (ZS11) rapeseed was used as a test material to verify the effect of the light formula of the present invention on promoting flowering and maturation of rapeseed. The ZS11 is a conventional rapeseed variety bred by the Institute of Oil Crops, Chinese Academy of Agricultural Sciences, and the operation process is as follows:

[0027] According to the LED light formula: within the range of 400-700nm, in the vertical space between the soil surface and the LED light source, the photon flux density is 350-1100μmolm -2 the s -1 ; In the range of 701-780nm, in the vertical space between the soil surface and the LED light source, the photon flux density is 120-550μmolm -2 the s -1 , wherein the ratio of the number of photons in the range of 600-700nm to that in the range of 400-500nm is 1.50-1.75, and the peak wavelength in the range of 400-500nm is at 450±5nm, the peak wavelength in the range of 600-700nm is at 660±5nm, 701- The peak wavelengt...

Embodiment 2

[0032] In this example, the 616R rapeseed variety was used as the test material to verify the promoting effect of the light formula of the present invention on the flowering and maturation of rapeseed. 616R is a restorer line of multiple high-yield and high-quality hybrid rapeseed varieties selected by the Huazhong Agricultural University Rapeseed Research Group. Its flowering is earlier than ZS11 in the field environment. Its growth cultivation process is identical with embodiment 1.

[0033] The growth of each test material 616R in the test group and the control group was observed and counted respectively. The growth of the whole growth period of the two groups is as follows: Figure 4 , where CK is the control group and F64 is the test group. The results showed that the test group was the first to mature, and from germination, buds appeared on the 29th day, flowered on the 34th day, ended on the 43rd day, and finally matured on the 67th day; Buds, flowering on the 41st d...

Embodiment 3

[0036] In this example, the 621R rapeseed variety was used as a test material to verify the promoting effect of the light formula of the present invention on the flowering and maturation of rapeseed. 621R is a restorer line of multiple high-yield and high-quality hybrid rapeseed varieties selected by the rape research group of Huazhong Agricultural University. Its flowering is earlier than ZS11 but later than 616R in the field environment. Its growth cultivation process is identical with embodiment 1.

[0037] The growth of each test material 621R in the test group and the control group was observed and counted respectively. The growth of the whole growth period of the two groups is as follows: Figure 6 shown. The results showed that the material in the test group matured first, budding on the 38th day from germination, flowering on the 45th day, final flowering on the 56th day, and finally ripening on the 77th day; Buds appear in the first day, bloom on the 53rd day, end ...

Abstract

The invention discloses an LED light formula for promoting flowering and ripening of rape and application of the LED light formula. An LED spectrum is characterized in that in a range of 400-700 nm, in a vertical space between a soil surface layer and an LED light source, the photon flux density is 350-1100 [mu] mol m <-2 > s <-1 >; in the range of 701-780 nm, in the vertical space between the soil surface layer and the LED light source, the photon flux density is 120-550 [mu] mol m <-2 > s <-1 >, and the ratio of the number of photons in the range of 600-700 nm to the number of photons in the range of 400-500 nm is 1.50-1.75. According to the LED light formula, the LED light formula is explored from the aspects of the distribution range of the LED spectrum, the photon flux density, the photon number and the like, the flowering time and the maturing time of the rape are effectively shortened, the bred rape offspring seeds are sufficient in number and reliable in quality, breeding of a new rape variety is accelerated, and the LED light formula has wide application prospects in the fields of mutant screening, tissue culture seedling growth acceleration, light source design of plant factories and the like.

Description

technical field [0001] The invention belongs to the technical field of rapeseed planting, and in particular relates to an LED light formula for promoting flowering and maturation of rapeseed and its application. Background technique [0002] Rapeseed is an important source of edible vegetable oil and feed protein, and it is also one of the most widely planted oil crops in my country. Since the establishment of classical genetics theory, breeding theory has developed extremely rapidly, and major achievements have emerged, such as hybrid breeding, utilization of heterosis, backcross breeding, and mutation breeding. On the basis of these theories and technologies, and thanks to the continuous progress of cultivation technology and biotechnology, the total output of my country's rapeseed has increased from 887,000 tons in the early days of the founding of the People's Republic of China to the current 12 million tons. Traditional breeding methods have made great contributions to...
