The invention discloses a grass planting method under a grazing-light complementary grassland slope photovoltaic module, relates to the technical field of photovoltaic power generation and ecological restoration, and aims to solve the problem that in the prior art, normal growth of grass seeds in the area is difficult to guarantee by common spray-seeding density. The method comprises the following steps: S1, pretreating a side slope, cleaning sundries on the side slope below a photovoltaic module mounting area, and digging steps in an area with the gradient being greater than 30 degrees, so that the distance between the step layout and a photovoltaic module array is kept at a safe distance of 0.5-1m; s2, soil improvement: soil shielded by the photovoltaic module is detected, lime is added into the detected acid soil to adjust the PH value to 6.5-7.5, and when 10-15 kg of decomposed cattle and sheep manure is mixed in each square meter, the range of 50 cm of a module foundation embedded part needs to be avoided; s3, grass seed selection and treatment, wherein grass seeds with the proper shade-tolerant adaptation degree are selected. The method has the advantages that the problem that the germination rate of grass seeds is low in a weak light environment is solved, and the slope vegetation coverage rate is effectively guaranteed.

The invention discloses application of GmPHYB in regulation and control of shade tolerance of soybeans, the GmPHYB comprises GmPHYB1 and GmPHYB2 genes, and the sequences of the GmPHYB1 and GmPHYB2 genes are highly homologous, so that the GmPHYB is collectively called as GmPHYB. The invention also discloses application of a GmPHYB-related biological material, such as a GmPHYB-coded protein, a GmPHYB-containing recombinant expression vector, a recombinant bacterium or a transgenic cell line, to regulation and control of the shade tolerance of soybeans. The recombinant plant expression vector containing the GmPHYB gene is transferred into the soybean, and the soybean plant has stronger shade tolerance and density tolerance; the high shade-tolerant soybeans obtained by the method have important application value, and are particularly suitable for cultivating soybean varieties suitable for strip-shaped compound planting and close planting.

The present invention relates to a novel Korean velvet grass variety 'KVX' of the genus Zoysia, and a specific marker for identifying 'KVX', and more specifically, relates to 'KVX' (Accession No: KCTC16100BP), which is a novel Korean velvet grass variety having resistance to high temperature-high humidity stress, low-mowing and shade tolerance, longer green color retention, and ultra-fine leaves.

The present application relates to the technical field of corn breeding, in particular to a medium-high altitude corn shade-tolerant and disease-resistant nutrient variety breeding device and method, which comprises a material placing plate and a multispectral imaging module suspended above the material placing plate. The top surface of the material placing plate is provided with a plurality of material grooves in a dot matrix pattern for separately placing corn kernels. The multispectral imaging module is composed of a ring array of LED lamps, a visible light camera, a near-infrared sensor, and an ultraviolet excitation light source. The multispectral imaging module synchronously acquires RGB, NIR, and UV three-channel images of the kernels. Through the morphological analysis algorithm built in the image processing unit, the distribution coordinates of unqualified corn kernels are obtained. Then, the image processing unit activates the electromagnetic iron to make the connecting pipe, air hole, and air tube correspondingly communicate. At the same time, the air pump is started to supply air to each air tube, and then the identified corn kernels in the material grooves are blown out, thereby improving the accuracy and efficiency of screening shade-tolerant and disease-resistant nutrient variety kernels.

The application discloses a treatment method for improving shade tolerance of Nymphaea tetragona Georgi, and the treatment method is used for treating Nymphaea tetragona Georgi seedlings under 45% shade through an exogenous substance, and after 30 days of shade treatment, diluted GA3 and ALA are directly applied in water, the water capacity in the pot is kept at about 50 L, after 15 days of chemical substance treatment, morphological indexes and photosynthetic characteristic indexes of the Nymphaea tetragona Georgi are determined, fresh, complete and disease-free Nymphaea tetragona Georgi leaves are taken, and physiological and biochemical indexes of the Nymphaea tetragona Georgi leaves are measured. The application can improve the flowering amount and the leaf number of the Nymphaea tetragona Georgi under shade, and can improve the net photosynthetic rate of the Nymphaea tetragona Georgi leaves, so that the shade tolerance of the Nymphaea tetragona Georgi is improved. The application is simple in operation, convenient to use, and can be widely applied to Nymphaea tetragona Georgi planting in dark environments, and lays a foundation for realizing shade-tolerant Nymphaea tetragona Georgi pot flower production suitable for family horticulture.

This invention discloses a rapid identification method for soybean shade tolerance and its application, belonging to the field of plant breeding technology. The method includes: planting soybean materials under continuous shading at a shading rate of 30% ± 2%; measuring plant height, average internode length, stem diameter at the fifth internode, and petiole length of the largest leaf on the main stem in both the shaded and control groups at 50 ± 3 days after emergence; calculating PHS, ILS, STS, and PLS; calculating a comprehensive evaluation value using the D-value calculation formula; and classifying the materials into three shade tolerance levels—strong, medium, and weak—based on D values ​​≥ 0.65, 0.45 ≤ D value < 0.65, and D value < 0.45. This invention, by optimizing the measurement period and shading rate, combined with a multi-index comprehensive evaluation model, shortens the identification cycle to within 50 days, achieving a consistency rate of over 90% with actual field performance. It can be widely applied to soybean shade tolerance breeding, germplasm resource screening, and variety evaluation.
